Charles Whitfield has written book about his findings that environmental traumas cause most psychiatric disorders. Perhaps because I went into medicine from postgrad science I always looked into patients personal histories for the cause of their emotional disorders, and found that this was so successful that drugs were seldom needed. I had several courageous psychotic patients who trusted me enough to work with me to discover the trauma that had caused their condition: it was in infancy, when our right cerebral hemispheres are learning and developing, and our left brains haven’t yet developed their linguistic abilities. Recovery required not only insight, but often nurturing to replace what we mammals require. Darwin had to remind us that we are animals who’ve evolved, and I sometimes wonder if we forget that we are mammals who are born very prematurely in order to get our big heads through the birth canal.
