I often read these articles where they say that so and so differences have been found in the brains of schizophrenics, bipolars, OCDers etc., or that certain brain differences have been found in people who have certain behavioral traits or intelligence levels, using imaging and other techniques.
If these brain differences are conclusive and reproducible, why are they not used in making a diagnosis of these illnesses/behaviors in people? Is it because it is simply not necessary?
Let's say I took 20 people. Among these 20 people, one person is bipolar, one is schizophrenic, one has OCD, one is a psychopath and one has a very high IQ. Apart from this, let's assume that all of them are sane in the sense that they have decent lives and jobs and none of them give the appearance of being "insane" (ever heard of high functioning schizophrenics who are professors etc.?). Can you brain scan these people and say which person has which illness/behavioral trait?
Apart from this, what about genetic testing? Can you do genetic testing and find out which person has what traits?
