Study Notes
- Schizophrenia involves various kinds of delusions, including persecution, grandeur, and thought control, as well as hallucinations with varying severities
- Hallucinations can affect any sense and range from strong, perception-absent experiences to milder distortions of reality
- Disorganized speech and behavior are common symptoms, with speech sometimes resembling word salad and behavior exhibiting strange, purposeless actions
- Negative symptoms include diminished emotional expression, low motivation, and disorganized behavior
- Schizophrenia is highly heritable, with concordance rates of approximately 48% for identical twins and 13-15% for fraternal twins
- Schizophrenia is influenced by both genetic and environmental factors
- Inherited genetic risk factors for schizophrenia include cellular signaling changes and structural brain changes
- Chlorpromazine was the first modern treatment for schizophrenia, discovered by chance
- Dopamine is a neurotransmitter implicated in schizophrenia, and antipsychotics work by blocking D2 dopamine receptors in the striatum
- The Dopamine Hypothesis suggests that blocking dopamine in the striatum leads to antipsychotic effects, but it doesn't fully explain the complexity of the disorder.
- Among the 1/3 of schizophrenia patients who respond to antipsychotics, negative symptoms are not always improved
- A therapeutic lag of 2-3 months is observed between schizophrenia patients receiving antipsychotic treatment and experiencing symptoms improvement
- Early antipsychotics worsened negative cognitive symptoms, suggesting a potential role for reduced dopamine in the prefrontal cortex.
- The best dopaminergic drugs only help some symptoms in some patients.
