How may antidepressants worsen the long-term outcome of depression?

Robert Whitaker in his latest posting on his Mad in America blog (to which I have referred before) elaborates on the work of Giovanna Fava about the vulnerability to relapse created by taking antidepressants. Fava has produced a recent review in which he builds on his hypothesis that the neurobiological mechanism underlying the increased vulnerability is due to oppositional tolerance. By this he means that the effects of the drug are opposed or counteracted by homeostatic changes in the brain, and when drug treatment ends, these processes may operate unopposed.

I am cautious about calling the effect 'tolerance'. Unlike, for example, alcohol, there is no evidence of the need to increase the dose or concentration of antidepressants to produce the desired effect. Maybe what Fava means is a tolerance-like effect.

More fundamentally, I'm not convinced that looking for an underlying neurobiological explanation is the real way to look at the issue. Surely the problem is psychological dependence. As I've said in a previous post, doctors concentrate too much on the physiological explanation of drug effects. People form attachments to their medication more because of what they mean to them than what they do. It's an identity-altering experience taking antidepressants. Discontinuing them is going to cause all sorts of problems which take time to make sense of.

The official view about mental illness

I was not intending to be personal about the bloggers on Healthy Minds. Heathy Lives. in two of my previous postings (see link to the first and to the second). The reason I've focussed on this blog is because it's published under the auspices of the American Psychiatric Association (APA). It therefore has the official backing of American psychiatry.

I've expressed concern before about the biomedical bias which has developed within the APA (see article). It's not so long ago that the APA was more pluralistic. Although I stand to be corrected, I think the Royal College of Psychiatrists in the UK would be more cautious about tying its ideological understanding of mental illness, at least in official statements, to a biomedical model.

Loren Mosher resigned from the APA in 1998 saying it had become the American Psychopharmacological Association rather than the American Psychiatric Association (see his resignation letter). Will the Healthy Minds. Healthy Lives. blog allow a debate about this situation? I doubt it, which I think is a cause for concern.

More on stigma of mental illness

The psychiatrist, Gariane Phillips Gunter's, MD, latest blog on Healthy Minds. Healthy Lives. has a video of her in which she argues that mental illnesses are "not your fault" because they are “biological illnesses, just like having high blood pressure, diabetes or cancer". She believes her crown as Mrs United States 2008 gave "her a greater opportunity to be a voice across this great nation for patients with mental illness and their families".

Reducing stigma is welcome but should not be based on a speculative biological theory of mental illness. As mentioned in the previous post, such a theory could actually increase stigma, as it doesn't really promote understanding of mental illness. As I keep saying, please do not misunderstand me. Of course, our thoughts, behaviour and emotions have their origins in the brain, but if that's all that Dr Gunter's saying, it's merely tautologous. However, she's making a statement about how we understand the world and it's not right.

Genetic theory not cure for stigma of ADHD

Ben Goldacre, in an article in his Guardian Bad Science column, comments on the Lancet ADHD study (as have I in a previous post). What he emphasises is that in fact a genetic theory of ADHD may actually potentially increase, not decrease, the stigma of the condition by encouraging a social distance from people identified as genetically damaged.

Can there be an open debate about biomedical psychiatry?

Robert Whitaker, in a posting on his Mad in America blog, writes about how he sometimes loses the hope that "our society will ever be able to have a thoughtful, honest discussion about what is truly known about mental disorders, and about the merits of psychiatric medications". I understand the sentiment. However, we do need to remind ourselves that biomedical psychiatry is a cultural system. Like a religion, it expresses a view about the nature of the world that provides what Clifford Geertz called an 'aura of factuality'. This feeling of realness is not easy to upset. People don't want to have their worldview turned upside down.

Whitaker's books The Anatomy of an Epidemic and Mad in America are well worth reading. One of their main themes is the vulnerability created by taking psychotropic medication. Relapse rates when people stop medication are very high. There is also evidence of a loss of benefit emerging with long-term treatment and also on retreatment after discontinuation of treatment. People may actually do better over the long-term if they work through their problems without medication. This is a legitimate scientific hypothesis (eg. Can long-term treatment with antidepressant drugs worsen the course of depression?).

Psychosocial theory of ADHD does not blame parents

Sarah Boseley's report in the Guardian about the Lancet genetic study of ADHD, which concludes in the paper that ADHD is not purely a social construct, quotes Professor Anita Thapar, the senior author of the study, as saying that she hopes "that these findings will help overcome the stigma associated with ADHD". She's confident that ADHD is a genetic condition, which, to her mind, shows she was right that ADHD should not be dismissed as being due to bad parenting or poor diet.

Avoiding blaming the parents is commonly used as an argument for a biomedical view of ADHD and other mental disorders, such as schizophrenia. However, it's a misunderstanding of the psychosocial perspective to take this as its implication. Trying to understand why a child becomes hyperactive is several steps away from blaming anyone. There's no suggestion that there's any conscious intention to cause harm and there is no one-to-one causal connection. Understanding reasons is not the same as causal connections.

Oh no, not another neurobiological theory of depression

When I initially read Scicurious' posting on the Guardian Science blog, I wondered whether it was a spoof. But no, there are some references in the literature to antidepressants increasing neurogenesis in animals. Scicurious wonders whether this may be the mechanism of action of antidepressants, as she's given up on the low serotonin theory of depression.

Scicurious blogs at Neurotic Physiology. She makes clear her view on her About Scicurious page that "we have [now] discovered that all “neuroses” and psychiatric disorders have a physiological basis". I don't want to undermine her faith, but she should make it clear she's just promoting her belief and not call it science.

She notes that "antidepressants do work in some patients". As I've said in a previous post, the way in which they work may be merely as amplified placebos.

Adult executive brain dysfunction

Felicia Wong, in a posting on the Healthy Minds. Healthy Lives. blog (the American Psychiatric Association’s online resource for mental health issues), refers favourably to a Wall Street Journal article on adult ADHD. As the article says, ADHD is "thought to be an imbalance in neurotransmitters, the chemical messengers that relay signals in the brain, particularly in the frontal cortex that governs planning and impulse control." Ivan K. Goldberg, a psychiatrist in New York City, who co-developed a commonly used screening test, is quoted as saying "What it really is is a disturbance of the executive functions of the brain".

Dr Wong recommends that those who suspect they have ADHD should have a thorough evaluation with a psychologist or psychiatrist. How do psychologists or psychiatrists know if there is an executive brain dysfunction? It's an hypothesis but how do we know whether it's true? Using the screening test co-developed by Dr Goldberg is not a diagnostic test, although there are rating scales used for diagnosing ADHD. But they're not measuring executive brain dysfunction. So what is being diagnosed when a diagnosis of adult ADHD is made and why link it to speculation about executive brain dysfunction? It's just a convenient way of viewing the world, isn't it?.

Does it matter whether biomedical psychiatry is true or not?

Lesson 5 of the NIMH course curriculum on mental illness, mentioned in a previous post, looks at the problem from the diagnosed children's perspective. Like any other kid is a video in three parts.

Regarding their problem as caused by a brain disorder has helped to make sense of their situation for these young people. Biomedical psychiatry can provide a genuine order to the world. Does it matter whether it's true or not?

Mental illness as faulty circuits in the brain

Research in mental health has moved on from chemical imbalances as the cause of mental illness to circuitry dysfunction in the prefrontal cortex, at least according to Thomas Insel, Director of NIMH. For example, in his article Disruptive insights in psychiatry: Transforming a clinical discipline, he says aspects of schizophrenia can be mapped onto dysfunction of dorsolateral prefrontal circuits that mediate executive function; depression appears to involve dysfunction in a region of the midline infragenual prefrontal cortex important for regulation of mood; OCD (obsessive-compulsive disorder) involves dysfunction in the orbitofrontal prefrontal cortex via its role in perseverative behaviours; and posttraumatic stress disorder (PTSD) can now be mapped to dysfunction in prefrontal circuits required for the extinction of fear.

There is of course some localisation of function in the brain but dynamic interactions between multiple regions produce thought, emotion and behaviour. It's a long step to mapping specific mental illnesses to dysfunction of brain circuits. Insel himself concedes that more research is needed.

Moreover, Insel clearly juxtaposes his concept of mental illness as brain disorder with psychological disorders caused by psychic trauma or conflict. He says we need to rethink our approaches to diagnosis, treatment, and professional training. So he's happy for his approach to encourage psychosurgery and intracranial brain stimulation.

He got an airing of his views in an article, Faulty circuits, for the popular Scientic American. His claim that neuroscience will revolutionise psychiatry is no different from the one made by modern psychiatry since its origins with the asylums. How many more blind alleys will psychiatric research lead us down? Faulty brain circuits in mental illness are as much of a myth as biochemical imbalances.

Psychiatrists rarely think about the impact of medication on anything other than brain chemicals

David Karp in his book Is it me or my meds?: Living with antidepressants talks about how one's view of oneself is at stake in taking antidepressants. In an earlier paper, he described the initial resistance to drug taking; negotiating the terms of treatment; adopting new rhetorics about the cause of depression, such as "chemical imbalance"; experiencing a conversion to medical realities; and becoming disenchanted with the value of medication for solving personal problems. Adopting the view that one suffers from a biochemically based emotional illness can be an identity-altering view of reality.

The obvious effects of antidepressants

Edward Shorter, in his book, Before Prozac, rues the fact that there has been no progress in the pharmacological treatment of mood disorders, since imipramine was introduced in the 1950s. He quotes from Roland Kuhn, who discovered imipramine, and who "never used 'controlled double-blind studies' with 'placebo', 'standardised rating scales' or the statistical treatment of large numbers of patients". Instead, what Kuhn noticed was an "obvious effect" in improving vital depression in psychiatric patients that he tried it on. To use a quote, again from Kuhn in Shorter (2009), "The patients become generally livelier, their depressive whisper voices become louder, the patients appear more social, the yammering and crying come to an end."

As I pointed out in a previous post, how do we know that antidepressants aren't just placebos with side effects? What Kuhn may have "discovered" was merely the placebo effect.

Shorter thinks we may have "lost something" because today "Kuhn would be kicked out of the door at the FDA", by which he means imipramine would never have come onto the market without controlled trials to support it. As he says, what we've got at the moment is a "mesh of patent-protected remedies". I agree this isn't progress, but Kuhn may have merely sent us down the route of the wish-fullfilling phantasy of the chemical cure of depression.

Academic freedom for critical psychiatry

As a follow-up to my post on Why haven't professors of psychiatry used their tenure to go up against the system that we’re in?, I suppose Thomas Szasz is the exception that makes the rule. There's a tweet that agrees with me. I guess Szasz has been lucky to have tenure.

The best article that explained what happened to Szasz when his tenure was threatened is by Ronald Leifer. Perhaps I'm just jealous that I've had to carry on in the real world of psychiatric practice and not had the freedom of tenure like Szasz, still going aged 90.

Am I a bromide?

Now Nassir Ghaemi has called me a "bromidic anti-biological critic". I have reviewed his book The rise and fall of the biopsychosocial model, which I mentioned in a previous post. He has replied to my review and I have responded to his comments. I can understand him being upset about my views about his book. But I have gone on at length about the misunderstanding of saying that critical psychiatry is anti-biological (eg. see another previous post).

By the way, bromides were used as sedatives in psychiatric hospitals in the past. And I don't think critical psychiatry is bromidic in the sense of being conformist to majority opinion. Maybe I should be happy to be bromidic in the adapted words of the song from South Pacific:-

Wonderful critical psychiatry 

I expect everyone of my crowd to make fun of my proud protestations for critical psychiatry. 

And they'll say I'm naive as a babe to believe that the fables of psychiatry will be exposed. 

Fearlessly, I'll face them and argue their doubts away. 

Loudly, I'll sing about flowers in spring. 

Flatly, I'll stand on my little flat feet and say.... Critical psychiatry... is a grand and a beautiful thing. 

I'm not ashamed to reveal, the world famous feeling I feel. 

I'm as corny as Kansas in August, 

I'm as normal as blueberry pie, 

no more a smart little guy with no heart, I have found me a wonderful cause. 

I am in a conventional dither, with a conventional star in my eye. 

And you will note there's a lump in my throat, when I speak of that wonderful cause. 

I'm as trite and as gay as a daisy in May a cliché coming true, 

I'm bromidic and bright as a moon happy night pouring light on the dew. 

I'm as corny as Kansas in August, high as the flag on the 4th of July. 

If you'll excuse an expression I use... 

I'm committed, I'm committed, I'm committed, I'm committed, I'm committed, I'm committed to a wonderful cause! 

(interlude) 

I'm as trite and gay as a daisy in May a cliche' coming true. 

I'm bromidic and bright as a moon happy night pouring light on the dew. 

I'm as corny as Kansas in August, high as the flag on the 4th of July. 

If you'll excuse an expression I use... I'm committed (13x) to a wonderful cause! 

 (To the music of "A wonderful guy" from South Pacific)

Why haven't professors of psychiatry used their tenure to go up against the system that we’re in?

Profile of Leon Eisenberg who died last year. I've always found some of his articles seminal eg. The social construction of the human brain.

Arthur Kleinman's obituary comments are pertinent. Eisenberg "follows in the great footsteps of ... William James, because James argued powerfully for the broad range of normal experience, for our tolerance of multiple ways of being human." (WPA obituary). “He was a major voice in American medicine." (Boston Globe obituary)

Why have I been called a postmodernist?

Nassir Ghaemi in his book The rise and fall of the biopsychosocial model says I am an "explicit proponent of applying postmodernism to psychiatry". His evidence for this is said to be my 2002 BMJ article.

In the article, I say that "Psychiatry needs to return to a biopsychological view to limit its excesses". True, I do go on to say that "Such an approach conforms to the new direction that has been called "postpsychiatry" and there is a box summarising the central tenets of postpsychiatry.

What I meant by this is that postpsychiatry is one form of critical psychiatry, which, as far as I am concerned is about 'returning to a biopsychological view'. Ghaemi has got it right that I am trying to rehabilitate the ideas of Adolf Meyer (whose perspective was called Psychobiology) (eg. see my article Adolf Meyer's psychobiology and the challenge for biomedicine).

I see postpsychiatry as one form of critical psychiatry (see my letter to Psychiatric Bulletin). Personally I take a more pragmatic view than postmodernism. In fact some would juxtapose critical psychiatry and postpsychiatry even more than I would eg. see entry for Critical Psychiatry on Wikipedia.

How do I get confused with Digby Tantam?

Tom Szasz in his new book Antipsychiatry: Quackery squared quotes my critical psychiatry website page on 'What was antipsychiatry?' but attributes it to Digby Tantam, not me. What I wrote was, "A key understanding of 'anti-psychiatry' is that mental illness is a myth (Szasz 1972)." Szasz objects to this because he is not an anti-psychiatrist. However, unfortunately for him, it is true that he has been identified with anti-psychiatry, and the myth of mental illness is a key idea that is associated with it.

I don't feel too bad about Szasz's criticism as he calls RD Laing an anti-psychiatrist, and Laing disowned the term, like Szasz.

He also complains that I put the date of his The myth of mental illness book as 1972, because of course it was first published in 1961. I did this because I was referring to the Paladin edition, which was first published in 1972.

Antidepressants are placebos with side-effects

Irving Kirsch's new book The Emperor's new drugs: Exploding the antidepressant myth makes the strongest case yet for antidepressants being merely amplified placebos. Irving does not make reference to a paper by Thomson (1982), which I think was the first to suggest this specific hypothesis. There were also previous references to the importance of the breaking of the blind in clinical trials.

I have always been sceptical about the value of antidepressants and psychotropic medication in general (eg. Limitations of double-blind trials) and share this lack of evidence with patients in my clinical practice. However, I have always felt it has been very difficult to get away from the notion that, however small the difference is between active and placebo groups in clinical trials, there is still a statistically significant difference. If patients have wanted an antidepressant I have felt I have had no choice but to prescribe.

Irving is more confident in his presentation of the case than I have been that this statistical difference is an artefact. Perhaps he has been more definitive because he started from a belief in antidepressants, which he no longer has, whereas, having always been sceptical, I have tended to qualify my position eg. Why is the effect size so small?.

Irving's evidence is summarised on page 21 of his book:-

The final piece of evidence to which he makes reference ie. a paper by Barbui et al is still to appear in print entitled 'Is the paroxetine-placebo efficacy separation mediated by adverse events?' As Irving says, the evidence "may not be conclusive proof, but it is strong". It'll be interesting to see the impact of this more confident case.

Critical psychiatry is not neurophobic

An article by Bullmore et al entitled Why psychiatry can't afford to be neurophobic followed up Craddock et al's article mentioned in my last post. It suggested that "there seems to be a deep-seated reluctance to embrace the theoretical and therapeutic potential of neuroscience for psychiatry".

I don't think this reluctance comes from critical psychiatry as such. It has always emphasised the integration of mind and brain. It's a mistake to think that mental symptoms are not based on a neural substrate. Critical psychiatrists can understand the wish, as much as anyone else, that neuroscience could solve the theoretical and therapeutic problems of psychiatry.

The problem is that fulfilling that wish is "intellectually bold" in Bullmore et al's own words. They are fearful that psychiatry will be cast "adrift from the core principles of medicine". They can't understand why anyone would want to prescribe psychotropic medication without thinking that symptoms were "somehow related to abnormal synaptic signalling between nerve cells".

Correspondence in reply (eg. by Andrew Blewett) sees through this argument. Neurohawkishness seems to be on the defensive.

Is there a debate about the future of psychiatry?

All in the Mind broadcast a programme that included a debate between Nick Craddock and Pat Bracken. It suggested there was a fierce debate within psychiatry about the very future of the profession.

I think the origin of this so-called debate is supposed to be an article by Craddock et al entitled "A wake-up call for British psychiatry". It has been portrayed as a biomedical reaction to the policy of New Ways of Working.

I think the issues are more complex (see my e-letter). There has been a deprofessionalisation of services in the sense of an undermining of professional expertise. New Ways of Working encouraged a fragmentation of services and, in fact, Department of Health policy now seems to have moved on to focusing on the "creative, capable workforce" and not so much about the structure of services.

The question is whether there is really a debate about the conceptual basis of psychiatry. Pat has always tended to argue that postpsychiatry is not another model (eg. see Openmind article). I may have misunderstood the implication of Pat's point but I do think there should be a debate about whether psychiatry has a biomedical or truly biopsychosocial foundation. "Biopsychosocial" may not be the best term as it has been used to mean an eclectic, atheoretical position. But I think critical psychiatry is clear that psychiatry can be practiced without postulating brain pathology as the basis for mental illness. That is a debate worth having but I haven't seen much engagement in it.

It may be illegal to discriminate against critical psychiatrists

It may now be illegal to discrimate against critical psychiatrists following a ruling that environmentalism is a belief system (see Guardian report). If green beliefs can come under employment regulations on discrimination (although not in the sense of merely belonging to the Green party), then it may well be illegal to discriminate against a critical psychiatrist (although not just because they are a member of the Critical Psychiatry Network or some other group).

Critical psychiatry seems to fit the 5 tests set by Mr Justice Burton:-

 The belief must be genuinely held
 It must be a belief and not an opinion or view based on the present state of information available
 It must be a belief as to a weighty and substantial aspect of life
 It must attain a certain level of cogency, seriousness, cohesion and importance
 It must be worthy of respect in a democratic society, not incompatible with human dignity and not conflict with the fundamental right of others.

Critical psychiatrists have been discriminated against. Trainees are worried that if they express an interest in critical psychiatry, their careers will be affected. Somehow this perception has got to change. A few legal challenges may help.

More advice on long-term prescribing of antidepressants needed

Study in the BMJ looking at why antidepressant prescribing has increased suggests it may well be due to people staying on antidepressants long-term. It only needs a small number to stay on them long-term to increase the total number of prescriptions dramatically.

The problem is that doctors get guidance about starting people on antidepressants but not much about when and how to take them off.

What's wrong with the pharmaceutical industry going bust?

Sarah Boseley has written a Guardian article about a Compass report "A bitter pill to swallow". The subtitle of the report is "Drugs for people, not just for profit".

The report tends to blame the neo-liberal market economics of Thatcher and Reagan for "why the drug companies are getting away with it". There are political changes that could be made, such as that all phase 3 trials be carried out independent from the industry. As the report says, this could be funded through an industry levy as initially put forward by John Abraham and Helen Lawton Smith in their book Regulation of the Pharmaceutical Industry. Doctors' education needs to be through public funding rather than relying on the pharmaceutical industry.

However, things won't really change until it's recognised how much doctors are merely agents of the pharmaceutical industry, rather than independent practitioners in the interests of patients.

More on disparaging postpsychiatry

Nice to have an oldfashioned radical like Rob Poole wading into the debate about postpsychiatry (see the e-letter from Robert Higgo and him in response to Pat Bracken and Phil Thomas's article in Psychiatric Bulletin - see also my previous post). And congratulations on his appointment as professor of psychiatry at Glyndwr University, Wrexham, which is a university that's obviously going somewhere.

I think what Rob and Robert are saying is that their books, Clinical skills in psychiatric treatment and Psychiatric interviewing and assessment are better than Pat and Phil's Postpsychiatry, but there's no need surely to be quite so rude about Pat and Phil's book. I will look at Rob and Robert's books and I'm sure there's something good in them, although I doubt whether they have the same "attitude of provisional scepticism" as Pat and Phil. Still, it's important to recognise the psychosocial emphasis of psychiatrists like Rob and Robert - they at least emphasise the link between mental health problems and poverty.

Let's try and elucidate the similarities and differences amongst psychiatrists that can look beyond a narrow biomedical model rather than get into a slanging match about postmodernism.

International Critical Mental Health Movement

Following the last Critical Psychiatry Network conference held in Norwich (conference website) there has been talk about setting up an International Critical Mental Health Movement. This is not an initiative of the Critical Psychiatry Network, which is a group of psychiatrists, mostly from the UK. It is important that the International Movement is widely based and inclusive.

Please post your comments. Expressions of interest and ideas about how to develop the movement would be welcome. It is envisaged that the International Movement would be open both to individuals and groups, so comments on behalf of organisations will be particularly welcome.

Please circulate interested people and organisations about this posting, so that they can also add their comments.

Critical psychiatry should not be dismissed as anti-psychiatry

At least Pat Bracken and Phil Thomas, advocates of postpsychiatry, have managed to get some response from mainstream psychiatry. They have an editorial in the Psychiatric Bulletin this month, which has an invited commentary from Frank Holloway to which they write an authors' response.

The problem is the way in which critical psychiatry/postpsychiatry gets dismissed as anti-psychiatry. It's not really clear what Frank Holloway means when he says the postpsychiatry project is strikingly similar to the anti-psychiatry of the 1970s. What he implies is that it doesn't really need to be considered. It'll end up in the same dead-end as anti-psychiatry, which was over the top anyway.

It is true there were excesses in anti-psychiatry (see my Historical perspectives on anti-psychiatry). However, the rotten reputation of anti-psychiatry should not be used to hide mainstream's psychiatry's defensiveness about the challenge of critical psychiatry, with which it does need to engage.

Pharmaceutical industry sponsorship of psychiatry conferences

The prospectus for industry sponsorship and exhibition at the 18th European Congress of Psychiatry in Munich in 2010 invites applications for different levels of benefits ranging from platinum to just an ordinary contributor. To obtain platinum, more than 75,000 euros (+VAT) needs to be paid out to be allowed to set up events such as official satellite symposia and "Meet the Professor" sessions. I doubt that the Congress Scientific Committee fails to approve many of these applications, perhaps particularly because the conference would lose the sponsorship money if it did. Full page colour adverts in the conference final programme are allowed by the best sponsors and there are other opportunities for advertising in the conference material. Educational grants in support of particular sessions can be acknowledged in the final programme.

Other options include buying congress bags and the notepads and pens and umbrellas to go in them, sponsoring the presidential dinner and contributing to the Young Psychiatrists' fund. Companies can advertise their logo on computer equipment in the cyber centre, in the facilities for young psychiatrists to review their presentations, in the Speakers' Ready Rooms, on the Congress webcast, and have their name attached to research prizes and scholarship programme winners awards. Just doing a straightforward exhibition also costs money.

I suppose the conference would not run without this sponsorship. Perhaps it's not really an educational event - more a marketing event.

Educational links between drug companies and medical education should cease, as several reports have suggested (eg. recent Royal College of Physicians report Innovating for health: Patients, physicians, the pharmaceutical industry and the NHS see BMJ news report). This means governments being prepared to meet their responsibilities by proper funding for medical education - it should be an element of Barack Obama's healthcare reforms, giving a lead to the rest of the world.

Pseudoneurobiology of addiction

According to an article in Journal of the American Medical Association (JAMA), "During the past 20 years, fundamental advances in the neurobiology of addiction have been made. Molecular and imaging studies have revealed addiction as a brain disorder with a strong genetic component, and this has galvanized research on new pharmacological treatments." This is said without reference.

In a follow-up letter, the authors clarify that they used the term addiction instead of dependence to avoid confusion with physical dependence. "Physical dependence results in withdrawal symptoms when drugs such as alcohol and heroin are discontinued, but the neuroadaptations responsible for these effects are different from those that underlie addiction (compulsive drug-taking condition with loss of control over the intense urges to take the drug even at the expense of adverse consequences)."

Brain mechanisms associated with reward are presumed to be disrupted. Of course, addiction or dependence, whatever you call it, is something to do with the brain. And it's also a habit that may be difficult to break, not least if it's associated with physical withdrawal symptoms. But it's sheer neurologising tautology (as Adolf Meyer used to call it) to think that anything has been explained by calling psychological dependence a brain disorder/disease. It doesn't make sense to say that psychological addiction is caused by a structural brain abnormality, rather than being a functional problem. If specific brain abnormalites have been found in addiction, we'd know what they are.

"I wanted to do something as important as the discovery of penicillin"

A New York Times interview with Nancy Andreasen, author of books, such as The broken brain. She reports what she calls the "big finding" that people with schizophrenia are losing brain tissue at a more rapid rate than healthy people of comparable age. Some are said to be losing as much as 1% per year. This data comes from an unpublished study following up schizophrenics. Andreasen seems to suggest the finding may be due to prefrontal cortical atrophy caused by antipsychotic drugs.

Andreasen says she "sat on" the findings because she didn't want people who need the drugs to stop taking them. Actually, there may be other non-specific reasons why people given antipsychotics have less brain tissue. Any drug effect on brain tissue also may not be of much consequence. But, the problem is the lack of debate. Andreasen is so wedded to the biomedical hypothesis that any potential negative repercussions of her views are suppressed.

How many people need to die each day for it to be an indictment of mental health services?

The Observer, the Liberal Democrats and Rethink argue that four people dying each day in contact with mental health services (Front page news story) shows that psychiatric help is inadequate. The data comes from incidents reported to the National Reporting and Learning Service (Quarterly data summary Feb 2009) resulting in death in mental health settings (most of which will have been suicides).

Actually this data isn't new. The National Confidential Inquiry into Suicide and Homicide by People with Mental Illness found 1367 cases of suicide (including open verdicts) of people in 2005 who had been in touch with mental health services within the last year, which is more than the number of NPSA incidents leading to death.

About 27% of people in England and Wales who commit suicide have been in touch with mental health services in the last year before their death. Suicide rates vary by country (see WHO data). Suicide is quite common, certainly in terms defined by the politics of mental health that it reaches the front page of a Sunday newspaper. What suicide rate is it reasonable for a country to have without blaming its mental health services?

Jonathan Leo's not a nobody and a nothing

Jammed by JAMA. Jonathan Leo used to be co-editor of the Ethical Human Psychology and Psychiatry journal. Even if the JAMA editor thinks he's a nobody and a nothing, he isn't. Even a Washington Post editorial talks about JAMA's hush-up. (With thanks to Vince)

Eating disorders 2009

Dr Ian Frampton has got a busy week coming up at the 9th London International Eating Disorders conference 2009, which explains how he's quoted in a story in the Observer Anorexia risk 'could be prevented'. He reckons children could be screened aged 8 to detect a brain problem in the insular cortex that makes them liable to develop an eating disorder. He apparently comes to this conclusion from neuropsychological testing of people aged 12-25 with anorexia nervosa. 70% of these people are supposed to have neurotransmitter damage or subtle brain structure changes or both.

We'll have to see if the papers he's presenting live up to the hype. Looking at the programme for the conference, he's the lead in 4 sessions. The first's called an accessible introduction to the clinical implications of advances in the neuroscience of eating disorders All in the mind? I guess the point he's going to make is that it isn't all in the mind, and that there must be some brain vulnerability in the insular cortex that makes some people more liable to anorexia than others. We then have his presentation of a global neuropsychological assessment in eating disorders. These are the first findings from the Ravello Profile collaboration. In the same short papers sessions, he's also got to present the first findings on testing the insular hypothesis. He rounds up on the last day convening the neuroscience special interest group.

Frampton is one of the authors of a paper from last September The fault is not in her parents but in her insula--a neurobiological hypothesis of anorexia nervosa. This is the element that is picked up by the chief executive of beat, the working name of the charity Eating Disorders Association, based in Norwich where I am. She is quoted in the Observer article as saying "It could pave the way for the first drugs to be developed to treat eating disorders, similar to the way that anti-depressants help rebalance the brain of people with depression. And it will help parents understand that they aren't to blame. Parents always blame themselves when their child develops an eating disorder. But what we are learning more and more from research in this area is that some people are very vulnerable to anorexia and that is down to genetic factors and brain chemistry, and not them trying to look like celebrity models or suffering a major traumatic event early in their lives. This research is a key missing part of the jigsaw of our understanding of anorexia."

This argument has been used to justify biological explanations of other psychiatric disorders, such as schizophrenia or ADHD. It's a misunderstanding of the psychosocial paradigm to suggest that understanding the reasons for something happening is necessarily anything to do with cause, in the sense of a proof of direct one-to-one correspondence.

And should Dr Frampton be allowed to have this publicity before he's even presented his findings? He's gone to the press even before his papers have been put to peer review in a journal.

Oh, and the conference is supported by the Huntercombe group, who have three hospitals for adolescent and young adult eating disorders. One of the convenors of the conference, retired psychiatrist, Bryan Lask, is Medical Advisor and Research Director for the Group.

Is UK improving dementia care?

I still haven't got round to reading the National Dementia Strategy as I said I would. Still the BMJ editorial about it is a good read. It agrees that the evidence for "a memory clinic in every town" is questionable. The French national plan for dementia sounds good.

Time for another hunger strike

NIMH are still getting away with saying that depressive illnesses are disorders of the brain without quoting any evidence. So they're agreeing with the American Psychiatric Association (APA) as I pointed out in my article from a few years ago.

There are massive research interests in psychiatry. If depression is not a disorder of the brain, it would potentially undermine what is called research and development, but despite saying that there have been improved treatments over the last 5 years the APA did not make any effort to explain what these improvements have been in response to a hunger strike in 2003. Would NIMH respond to a hunger stike?

Don't get an orgasm by pulling a rat out of your mouth

How can a cinema advert by Pfizer, the makers of Viagra, not mention the drug they make? By saying the real danger is counterfeit medicines. The European Alliance for Access to Safe Medicines, which has three out of seven Board Executives who are pharmaceutical representatives, has called the internet the Counterfeiting Superhighway.

And believe it or not, Pfizer has got support from the Medicines and Healthcare products Regulatory Agency (MHRA). But why should the Pfizer campaign focus on the UK which does not allow direct to consumer advertising (except through such campaigns?)?

Pfizer have produced a report Cracking Counterfeit which even pretends they are focusing on men because they're far less likely than women to visit or even be registered with a GP. Actually, as the company information says, Viagra is intended for use only by men. The senior chemist at Pfizer Counterfeit Lab is quoted as saying that rat poison has been found in a counterfeit blood pressure lowering treatment, but doesn't say which drug and doesn't say it's Viagra. By the way, Viagra does reduce blood pressure.

The MRHA makes reference to a brochure Counterfeit drugs kill produced by IMPACT. WHO says it has responded to the challenge of counterfeit medical products by creating a global coalition of stakeholders called IMPACT (International Medical Products Anti-Counterfeiting Taskforce), a partnership comprised of all the major anti-counterfeiting players, including: international organizations, non-governmental organizations, enforcement agencies, pharmaceutical manufacturers associations and drug and regulatory authorities. Why do they need pharmaceutical manufacturers organisations? Do they want them to run for them?

The IMPACT brochure says fake medicines led to a trail of death in Argentina in 2004. A woman was given 7 out of a course of 10 of what the Argentinian medicines authority called "highly toxic counterfeit injections" of an iron-based compound for anaemia, before she died of liver failure. Four people were prosecuted. A second woman injected with the same counterfeit drug gave birth to a 26 week premature baby. No other examples are given of counterfeit drugs causing a "trail of death".

The IMPACT report does point out that some internet pharmacies are completely legal operations. Pfizer uses the IMPACT brochure to say that substandard and counterfeit medicines can lead to death, as well as therapeutic failure and drug resistance.

Survey data found that 67% of men purchasing prescription erectile dysfunction medicine without prescription use the internet. Pfizer helpfully tell you that the legitimate sites that sell precriptions can be found listed at the Royal Pharmaceutical Society of Great Britain (RPSGB) www.rpsgb.org. They presumably get their cut from this site but not from the illegal ones.

Pfizer estimate that over £10 million pounds is potentially being poured into the counterfeit market in the UK. They quote the Centre for Medicine in the Public Interest as predicting that counterfeit medicine sales will reach approx 55.5 billion euros globally by 2010. The Wikipedia entry on this centre says it is "a non-profit medical issues research group which is partially funded by the pharmaceutical industry". Where's the public interest?

The suggestion is that men buy Viagra on the internet because it's cheaper and less embarassing. And they think it is like an over-the-counter drug. Could Pfizer make Viagra more cheaply? Is it too dangerous (watch out for the lowering of blood pressure and Pfizer give warning for cardiac risk of sexual activity in patients with preexisting cardiovascular disease) to be over-the-counter? Does it work?

By the way Pfizer is the world's largest pharmaceutical company. Who are the counterfeiters? Are the regulators doing their job?

And finally, Pfizer have even got Dr Mark Porter supporting them in the campaign. Is there a conflict of interest with his BBC job, presenting Case Notes on radio 4 amongst other activities?

Improving NHS dementia care

Emma Dent from HSJ's version of dementia strategy. Good to point out that programme of support and counselling at diagnosis can be helpful, although have to be a bit careful about using reduction in institutional care as outcome. The point of the strategy shouldn't just be about reducing number of beds. Relatives may well need respite and even permanent residential and nursing care for demented person considering the burden of care.

How much do care homes make? Are there any figures on this? The government had a choice years ago whether to develop its own provision and chose instead using the profit motive to get enough provision. There's no going back here, but some care owners seem to do quite well out of it. Perhaps they should, but elderly care is not about exploitation.

And I wouldn't like people just to concentrate on information. Looking after someone with dementia has a physical side which must not be ignored. Input is not just about information but also practical help if it's asked for. Dementia care isn't just about advice. Calling people advisors means they may say that's all they can do. What's wrong with calling them consultants? - oh, that's monopolised by the doctors.

Sube Banerjee is right that people do worry they are becoming demented, if that's what he is saying. But it's not just because they really are becoming demented. Information can increase as well as decrease fear, particularly if the problem is incorrectly assessed.

I'm not totally convinced about the resources argument. We have seen a pretty dramatic increase in provision. OK, but so has the rest of medicine as well. As with any mental health care, so much depends on how well it is organised and how good the staff are at understanding what's going on.

I'm not against drop in services. We're supposed to be having them in every local NHS anyway. Are the memory clinics supposed to be part of that set-up? This is getting a bit muddled. I will get to the actual strategy publication soon.

Dementia strategy published

Health Service Journal version. Are clinics the best way forward? Shouldn't people with dementia be seen at home? Isn't this the history of the development of old age psychiatry in this country? Perhaps history is being reversed.

Good that there's a clinical lead. Problem is that it must remain clinical, not some manager or governance person. There's too much of a divide between managers and professionals in the NHS in general, but maybe having a clinical lead for dementia will help resolve this conflict. But then why just for dementia?

As mentioned previously people with dementia, as opposed to people worrying they have dementia, may not be very good at self-refering. Where's the evidence that early intervention makes any difference? As for psychosis, just because people do worse the later you pick it up, does not necessarily mean that intervening earlier would really make any difference.

I'm not convinced by the strong leadership from the Department of Health idea. They're bureaucrats, aren't they? When did they last see a demented patient? Listen to the professionals.

Maybe the drug companies really are in trouble

GlaxoSmithKline to slash 6,000 jobs. Competition from generic manufacturers and doubts about company pipelines are posing a serious threat to the sector and ING analysts warned of an "intellectual property meltdown" as top-selling products come off patent and sales slow dramatically.

I wasn't so sure about this in my book review of Marcia Angell's The truth about drug companies: How they deceive us and what to do about it but maybe she was right.

Don't forget to look at the national dementia strategy this week

Health secretary Alan Johnson will unveil the national dementia strategy this week. The government's aim is to raise the profile of dementia, increase early diagnosis and improve the quality of treatment.

There may be a problem with encouraging people to seek early diagnosis. People are not very good at recognising they are dementing. This means dementia may be misdiagnosed when it is really benign forgetfullness or depression.

The drug companies must be laughing about the encouragement of mind-enhancing drugs. These are the same drugs which when I was training were said to be ineffective. Academic old age psychiatrists opposed their introduction then, but now seem to be encouraging the government strategy. Check out any conflict of interest.

Nor do I think there are any intervention studies for changes to diet and lifestyle. Just because there may be associations does not mean they are causal.

Thank goodness for better support for carers but what does it mean?

Campaign for animals treated with antidepressants

An offshoot blog has been created.

Where did depressed, unpredictable dog bite Jacques Chirac?

Another story about an animal (this time a dog) being treated for depression. This time the problem is unpredictable depression that caused the dog to bite Jacques Chirac, the ex-French president. As I said in the last post, the only licensed indication is for use in separation anxiety associated with behavioural training. It's not clear that the Chirac's dog has separation anxiety - he's living with them, not separated from them, as far as I know. Nor is there any mention of any other loss in the story. No-one seems to have asked why the dog bit Jacques. Nor does anyone seem very interested in where it bit him. The incident does seem serious though as the story describes it as a mauling and the ex-President was rushed to hospital. Should the depression be allowed to excuse the dog's behaviour?

Dogs are being given pills without the evidence. The story doesn't say what antidepressant Chirac's dog has been given. Presumably it's Clomicalm. This blog is prepared to start a campaign for animals being treated with antidepressants. Maybe it will be listened to more than one about humans.

Maybe as a first step someone needs to ask Novartis, the manufacturers of Clomicalm, how much they are making out of the drug. Help please. Join the campaign.

Number of tropical birds that require antidepressants is growing

Telegraph story - Parrot is taking Prozac for depression following the death of its owner. Actually it's not Prozac (fluoxetine), probably the most well-known of the newer antidepressants - well, newer in the sense it first went on the UK market in 1989 - but Clomicalm (clomipramine), a traditional tricyclic antidepressant. Most prescribing of psychotropic medication in veterinary medicine is outside licensed indications. According to a recent veterinary psychopharmacology textbook the only label uses in the US for the treatment of behaviour problems are Clomicalm for separation anxiety in dogs and deprenyl for cognitive dysfunction in elderly dogs. So Clomicalm for parrots is unlicensed.

The company product information says Clomicalm was tested in clinical trials involving client-owned dogs. When used in conjunction with behavioural training, Clomicalm accelerated both the time to improvement and the final result of separation anxiety therapy compared to behavioural training alone. So behaviour training is a necessary component of therapy with Clomicalm. Perhaps it doesn't work on its own. The Telegraph story doesn't say whether it worked for the parrot.
