NEGATIVE SYMPTOMS – AVOLITION: No Initiative – ALOGIA: Speech is Vacant – ANHEDONIA: No Pleasure – FLAT AFFECT: The Mask – ASOCIALITY: No Social Interest
Paranoid Delusions & Hallucinations Intact Cognition and Affect No Disorganized Speech Best Prognosis
Disorganized Disorganized Speech Disorganized Behavior Flat or Inappropriate Affect Delusions & Hallucinations ~Fragmented or lacking a theme Often Chronic
Catatonic Disorganized Speech Disorganized Behavior Waxy Flexibility, Rigidity, Odd Mannerisms, Mimicry Flat or Inappropriate Affect Delusions & Hallucinations Fragmented or lacking a theme Often Chronic
Undifferentiated Beginnings of Breakdown Major symptoms of Schizophrenia Do NOT meet other criteria Waste Basket philosophy
Residual Have had one episode Now mostly symptom-free >Q: Once a schizophrenic always a schizophrenic?
Causes of Schizophrenia Genetic Predisposition – Twin study evidence Neurotransmitters – Dopamine hypothesis Brain Structure & Function Family & Interactions – Double-bind theory – Schizophrenogenic mother
MAPPING THE BRAIN
Map reveals the 3-dimensional profile of gray matter loss in the brains of teenagers with early-onset schizophrenia ~with a region of greatest loss in the temporal and frontal brain regions that control memory, hearing, motor functions, and attention.
Approximate number of people in the United States suffering from: Schizophrenia: Over 2.2 million Multiple Sclerosis: 400,000 Insulin-dependent Diabetes: 350,000 Muscular Dystrophy: 35,000
FACTS & FIGURES
After 10 years, of the people diagnosed with schizophrenia: 25% Completely Recover 25% Much Improved, relatively independent 25% Improved, but require extensive support 15% Hospitalized, unimproved 10% Dead (Mostly Suicide) After 30 years, of the people diagnosed with schizophrenia: 25% Completely Recover 35% Much Improved, relatively independent 15% Improved, but require extensive support 10% Hospitalized, unimproved 15% Dead (Mostly Suicide)
Where are the People with Schizophrenia? …Approximately: 6% are homeless or live in shelters 6% live in jails or prisons 5-6% live in Hospitals 10% live in Nursing homes 25% live with a family member 28% are living independently 20% live in Supervised Housing (e.g. group homes, etc.) Approximately 200,000 individuals with schizophrenia or manic-depressive illness are homeless, constituting 1/3 of the approximately 600,000 homeless population (total homeless population statistic based on data from Department of Health and Human Services).
The 45 percent who acknowledged that they needed treatment ~(and thus had awareness of their illness) ~but still were not receiving treatment cited many reasons for this. These included (respondent could check several reasons): 32% "wanted to solve problem on own" 27% "thought the problem would get better by itself" 20% "too expensive" 18% "unsure about where to go for help" 17% "help probably would not do any good" 16% "health insurance would not cover treatment
