  2. Schizophrenia spectrum and other psychotic disorders are defined by abnormalities in at least two of these and is present for a significant portion of time during a 1-month period
    • *Delusions
    • *Hallucinations
    • *Disorganized thinking/speach
    • Grossly disorganized (abnormal) motor behavior or catatonia
    • Negative symptoms (loss of function)

    *Must include at least one of these
  3. Define positive symptoms
    • sensory amplification associated with agitation; highly distressing.
    • Includes delusions, hallucinations, disorganized thinknig or grossly disorganized or abnormal motor behavior
  4. Define negative symptoms
    • loss of function
    • accounts for most of the morbidity in schizophrenia
    • less pronounced in other types of psychotic disorders
  5. Define delusions
    • altered thought processes involving beliefs that are not consistent with reality
    • not abile to be reality-tested in light of conflicting evidence (not amenable to change)
  6. Define hallucinations
    altered sensory perceptions that are not consistent with reality and that occur without an external stimulus
  7. Types of hallucinations
    • auditory: most common
    • visual: next most common
    • tactile: may indicate need for neurologic examination as it may indicate withdrawal or a tumor
  8. Schizophrenia is associated with high morbidity and premature mortality of this length
    25-35 years earlier compared to general populations
  9. In addition to the effected psychotic processes, diagnosis of schizophrenia must also include:
    • a marked change in functioning since time of onset
    • continuous signs of disturbance persist for at least 6 months
    • Schizoaffective, depressive, and bipolar disorders have been ruled out
    • not attributable to effects of a substance or another medical condition
  10. Define schizotypal personality disorder
    • eccentricity
    • lack of overt psychotic symptoms
  11. Define delusional disorder

  15. Early pattern schizophrenia
    • peak 18-25 years
    • more often male
    • poor baseline functioning and structural brain abnormalities
    • prominent negative symptoms
    • poor prognosis with earlier onset and decreased level of function
  16. Later onset schizophrenia
    • peak 25-35 years
    • more often in females
    • less structural brain abnormalities
    • better outcome with therapy and medication
  17. Phases of schizophrenia
    • Phase I: acute
    • Phase II: stabilization
    • Phase III: maintenance/recovery
