After all there are brain scans that prove this, aren't there? We've probably all seen pretty coloured scans that show areas of the brain lighting up when they are said to show connections to various human activities. But we’ve forgotten what our forefathers learnt in the late 19th/ early 20th centuries that human activity is not as well localised in the brain as we might have expected or hoped. They appreciated that the brain, indeed the complete human body, generally acts as a whole. It is also alive and cannot be explained in mechanistic terms.
Elliot Vallenstein's book Blaming the brain was first published in 1988. It described how theories of chemical imbalance in the brain had replaced previous ideas that early experience in the family were the cause of mental disorders. As the publishers website says (see webpage), the book sounded a “clarion call throughout our culture of quick-fix pharmacology and our increasing reliance on drugs as a cure-all for mental illness”. This situation has in fact only got worse since despite the warning. For example, over recent years, the neurodivergence movement has promoted the idea that our differences from each other are due to our brains. No wonder there is therefore a burgeoning demand for a neurodivergent diagnosis. If it’s believed that the reason why we’ve seen ourselves as different from each other all these years is because of our brain, then the sooner we get a diagnosis the better.
We need a serious rethink about the nature of mental disorder. It may have suited psychiatry to go along with the idea that mental illness is due to the brain. Of course brain abnormalities can cause mental symptoms. But most of the presentations to psychiatrists are not caused by a brain abnormality, however much psychiatrists may have misled people that they are.
