Lefties Are Also Crazy

In repeat studies of schizophrenics for the purpose of determining whether those with the disorder had a prevalent lateral preference, it was discovered that upwards of 40% of the schizoaffectives were left handed or more mix-handed. That means 4 in ten irrational patients were not right-handed, far more than their usual mix in the general population. Moreover, similar research suggests that lefties constitute a greater number of people suffering from ADHD and lesdyxia, um, dyslexia. Is it possible that while having easier access to more of your brain could be causing left-brain/right-brain usage confusion, like two baseball players running to catch the same fly ball and colliding?
