Description
Psychotic Disorders - Chapter 11 (Lect. 8) November 17, 2009 - [s] History of Schizophrenia - Kraeplin dementia praecox He first described symptoms associated with schizophrenia, but didnt label it as such Intellectual deterioration with early onset - Bleuler schizophrenia First coined this term in 1908 Means fragmented thoughts or split head (which may be why people use schizophrenia synonymously with dissociative identity disorder but theyre different; dissociative personalities vs. hallucinations) - Bleuler again - Group of schizophrenias We now know that there are a number of different subtypes of schizophrenia which can be extremely different (like catatonic vs. disorganized?) Probably one of the most researched disorders, but the reasons behind the causes and multiple symptoms are still a mystery Schizophrenia Diagnosis Two or more of the following must be present for a significant portion of the time during a 1 month period - Delusions - Hallucinations - Disorganized speech - Grossly disorganized or catatonic behaviour - Negative symptoms (lack of motivation, for example) Only one symptom is required in certain circumstances (bizarre delusions so bizarre that they cant possibly be true or hallucinations; multiple voices different from normal internal thought processes; conversing; running commentary one voice and commenting on what ones doing) Must cause significant dysfunction Must last more than 6 months (acute symptoms + residual symptoms) Though not necessarily active throughout that period of time; just needs to add up to 6 months Stuff about Schizophrenia Affects about 1% of the population (Twice as common anorexia, less common than bipolar) Happens at age 15-24 in males, and 25-34 in females Women seem to have a slightly better of a prognosis (maybe because it develops later, so they have more skills to work through the symptoms, or women experience fewer cognitive dysfunctions as a result of schizophrenia) Very high suicide rate (~10%) strongly correlated to (negative) auditory hallucinations Very common; ~8% of all hospital beds in Canada are for schizophrenic patients www.notesolution.com
