Much of the current problems of Psychiatry stem from the split of neurology and psychiatry [0]. Over the last 60+ years investigators have found many physiological considerations for the so-called "mental" disorders. The core of the resistance against psychiatry (slandered as "antipsychiatry") are the experiences of patients whose conditions deteriorate from medications that do not address the cause of their conditions.
Stress is one of the most important factors in every psychiatric diagnosis. Malnutrition is a type of stress; emotional stress and genetic mutations [1] creates a need for more of certain nutrients.

I appreciate Szasz's comment about the crucifixion of Ignaz Semmelweis, the Hungarian obstetrician who had the audacity to suggest that his fellow doctors should wash their hands between autopsies and childbirths:
"It taught me, at an early age, the lesson that it can be dangerous to be wrong, but, to be right, when society regards the majority’s falsehood as truth, could be fatal. This principle is especially true with respect to false truths that form an important part of an entire society’s belief system. In the past, such basic false truths were religious in nature. In the modern world, they are medical and political in nature." (emphasis added)
The enduring mistreatment of those labeled as "mentally ill" is one of the great tragedies of our time.
