Thanks for the article @CannonSalt.
I agree to a certain point however at the same time there are people with "mental" or cognitive symptoms that have no psycho-social issues (Ie:their external life and family is free of drama,their thinking style is good etc) and likewise there probably are also people those mental illness is purely caused by psych-social.
At any case,i think theres too much focus placed on trying to find a one size fits all illness model for each mental illness instead of an individualised approach.
Take psychosis or whats termed Schizophrenia for example-one persons symptoms may be caused by a traumatic resonse to sexual abuse as a child,anothers caused (or affected by smoking marijuana,anothers caused by a brain neurodegenerative process,a different persons caused by NMDAR antibodies due to an Ovarian tumor and so on....
