Study Notes

Introduction to Schizophrenia

Originates from Greek terms meaning "split mind."
Likely involves genetic predisposition, biochemical dysfunction, physiological factors, and psychosocial stress.
No single cure; requires multidisciplinary treatment approach.
Inflicts significant hospitalizations, family chaos, high costs, and increases in fear.
Approximately one-third of individuals attempt suicide; about 10% of those die by suicide.

Nature of the Disorder

Psychosis entails disorganized personality, diminished social functioning, and reality distortion with possible hallucinations and delusions.
Affects thought processes, perception, and emotional state, leading to severe functional deterioration.
Lifetime prevalence in the U.S. is about 1%.

Phases of Schizophrenia

Premorbid Phase: Indicators include shyness, poor relationships, school performance, and antisocial behavior; focuses on identifying biomarkers for early intervention.
Prodromal Phase: Characterized by significant functional decline, depressive symptoms in 50%, social withdrawal, cognitive impairment, and obsessive-compulsive behavior.
Active Psychotic Phase: Prominent psychotic symptoms like delusions and hallucinations, along with disorganized speech and decreased functioning in various life areas.
Residual Phase: Reduced prominence of active symptoms, flat affect, and worsened role functioning overtime.

Prognosis

Full return to premorbid functioning is uncommon.
Positive prognosis factors: good premorbid functioning, later onset, female gender, abrupt stressful onset, identified mood disturbances, brief active symptom duration, and minimal residual symptoms.
Normal neurological function and absence of structural brain abnormalities enhance prognosis.

Predisposing Factors

Biological Influences:
- Genetic role identified with lifetime risk at 1%, sibling risk at 10%, and child risk at 5-6%.
- Biochemical influences suggest excess dopamine plays a role; neurotransmitter abnormalities noted.
- Physiological factors potentially include viral infections and anatomical changes.
Psychological Factors: Earlier theories now deemed less credible; current emphasis on biological aspects.
Environmental Influences: Factors such as poverty and stressful life events can exacerbate symptoms and increase relapse rates; genetic vulnerability linked to psychosis, especially in adolescents using cannabinoids.

Other Schizophrenia Spectrum and Psychotic Disorders

Delusional Disorder: Includes specific types such as erotomanic, grandiose, jealous, persecutory, somatic, and mixed.
Brief Psychotic Disorder: Sudden onset without requiring a significant psychosocial stressor; lasts less than one month.
Substance-Induced Psychotic Disorder: Prominent hallucinations and delusions linked to substance intoxication or withdrawal.
Psychotic Disorder Associated with Medical Condition: Hallucinations and delusions directly related to a general medical issue.
