Schizophrenia is generally associated with lower IQ scores, even before symptoms appear, but the relationship isn't simple; while high IQ doesn't prevent the illness, some people with high intelligence develop it, sometimes presenting as a distinct subtype with manic symptoms and fewer negative symptoms, and there's no strong evidence linking high IQ to a greater risk, though genetic factors overlap. The strongest risk comes from a deviation below expected IQ, suggesting environmental or genetic factors impacting cognition can increase vulnerability, not genius itself.
