  1. Schizophrenia AP Psych CH 12

  2. Schizophrenia • A psychotic disorder involving distortions in thoughts, perceptions, and/or emotions. • “split or broken mind” • Split if from reality • Distorted perceptions • Can be experienced in different ways • World is bleak, empty • Filled with sensations, everything is confusing

  3. Symptoms Two or more of the following for at least 1 month • Hallucinations • Delusions • Disorganized bizarre speech • “clang” associations- compulsive rhyming or alliteration without apparent logical connection between words. • Word salads - confused usage of words with no apparent meaning or relationship attached to them • Disorganized or catatonic behavior • Emotions are dull, flat

  4. Word Salad Example The lion will have to change from dogs into cats until I can meet my father and mother and we dispart some rats. I live on the front of Whitton’s head. You have to work hard if you don’t get into bed…It’s all for a squab true tray and there ain’t no squabs, there ain’t no men…there ain’t no nothing besides my mother and my father who stand alone upon the Island of Capri where is no ice. Well it’s my suitcase sit. (Rogers, 1982)

  5. Symptoms (continued) Work impaired Interpersonal relationships impaired Self-care below level prior to onset Is NOT due to drugs

  6. Positive and Negative Symptoms • Positive symptoms – active processes (behaviors in addition to normal behaviors) • Hallucinations, delusions • Negative symptoms – passive processes (taking away a normal behavior) • Social withdrawal, lack of emotion, lack of thought, lack of movement (catatonic)

  7. Incidence • Onset occurs between the late teens and mid-30s • Cases of children 5-6 • Late onset (after 45) occurs more in women. • .5-1.5% of population • Account for about 40% of admissions to mental hospitals • 1/3 of patients will never recover

  8. Types of Schizophrenia Disorganized – incoherent speech, hallucinations, delusions, bizarre behavior Catatonic – motor dysfunctions – “catatonic stupor” remain motionless for hours to days, hold rigid statue-like positions

  9. Types of Schizophrenia • Paranoid – delusions and hallucinations without catatonic symptoms or disorganization of thought of speech. • Delusions or persecution or grandiosity (inflated self-importance) are common • Undifferentiated – does not clearly fit into previous three categories • Residual – suffered from schizophrenia in past, but not currently experiencing major symptoms; mildly disturbed thoughts

  10. Causes • Adopted children with no history of disorder in biological family run NO increased risk of developing if placed in home with schizophrenic parent (Gottesman, 1991) • Brain disorder • Positive symptoms linked to excess in dopamine • Antipsychotic drugs suppress dopamine • Abnormalities seen on some MRIs

  11. Causes • Nature • 10x more likely if first-degree relative • Identical twins – 48% chance of twin developing if other twin has it. • Two parents with schizophrenia -46% risk • Nurture • Being raised in a healthy family can lower a genetic predisposition

  12. Diathesis-Stress Hypothesis Speculative cause Genetic factors place an individual at risk Environmental stress factors transform the potential risk into actual schizophrenic disorder
