1% prevalence rate; starts in late teens and early 20s; evidence that schizophrenics have higher iqs. Not a mind split in two (multiple personalities), but a mind from reality. Positive symptoms: comes first; things that are there that should not be. Delusions: false belief; most common is paranoid delusion (often concerns technology) Hallucinations: false perception (through senses); most common is auditory. Inappropriate affect: emotion that is not appropriate for the situation. Negative symptoms: common during ages 40-50s; things that are missing that should be there; thought to be the result of morphological brain damage. Flat affect: no emotional response at all.
