Schizophrenia Different from DID- in schizophrenia, you don’t have 2 or more distinct personalities, rather, the split is a split from reality- the person lives in his or her own world/ reality First called dementia praecox (precocious dementia) by Emil Kraepelin, because of his belief that it results from premature deterioration of the brain. Eugen Bleuler later called it schizophrenia- from Greek schizein (to split) and phren (mind). Criteria 1. Symptoms: two or more of the following much of the time for a month (or less if treated)- Delusions: beliefs with little grounding in reality; ideas that an individual be- lieves are try but are highly unlikely and often impossible Hallucinations: unreal perceptual or sensory experiences. Disorganized speech and thought: grossly disorganized patterns of speech; fre- quent derailment or incoherence Derailment (loosening of associations): tendency to switch from one topic to a seemingly unrelated topic with little coherent transition Word salad: disorganized speech that seems totally incoherent Could be related to deficits in eye movement or working memory Grossly disorganized behavior or catatonic behavior: behavior that is highly un- predictable, is bizarre, and/or shows a complete lack of responsiveness to the outside world Catatonic excitement: person becomes wildly agitated for no apparent reas- on and is difficult to subdue Negative symptoms: no energy to do anything 2.
