Study Notes
The Course and Outcome of Schizophrenia
- The course and outcome of schizophrenia can vary from culture to culture.
- In the United States, there are disproportionately more African Americans diagnosed with schizophrenia compared to Caucasians.
- Studies show that the severity of a parent's schizophrenia influences the likelihood of their child developing it.
- The more severe the parent's disorder, the more likely the child will inherit it.
- There is a higher incidence rate of schizophrenia in men.
Genetics Influence
- Genes play a role in making some individuals vulnerable to schizophrenia.
- Regions of chromosomes 1, 2, 3, 5, 6, 8, 10, 11, 13, 20, and 22 are implicated in schizophrenia.
- Three of the most reliable genetic influences on schizophrenia include NRG1 on chromosome 8, DTNBP1 on chromosome 6, and COMT on chromosome 22.
- Identical twins share 100% of their genes and 100% of their environment, whereas fraternal twins share only about 50% of their genes and 100% of their environment.
- Identical twins, despite sharing genes, can have different prenatal and family experiences, resulting in varying degrees of biological and environmental stress and different outcomes.
Brain Structure
- Research suggests evidence of neurological damage in people with schizophrenia.
- Many children with a parent with schizophrenia demonstrate subtle neurological problems, such as abnormal reflexes and inattentiveness.
- Adults with schizophrenia show deficits in task performance and attention during reaction time exercises.
- Enlarged ventricles are observed more frequently in men than in women.
Expressed Emotion
- Expressed Emotion (EE) refers to a communication style characterized by high levels of criticism, hostility, and emotional overinvolvement.
- Research has indicated that families with high EE view schizophrenia symptoms as controllable and attribute them to patients' lack of effort.
- High EE has been linked to an increased risk of relapse after initial symptoms are observed.
- People with schizophrenia living in families with high EE are 3.7 times more likely to relapse compared to those in families with low EE.
Treatment of Schizophrenia
- Treatment usually begins with neuroleptic drugs to reduce symptoms.
- Psychosocial treatments are combined with medication to reduce relapse, compensate for skill deficits, and improve cooperation with treatment.
- Researchers believe schizophrenia requires biological intervention due to its neurological basis.
- The disorder was initially viewed as a brain disease in the late 19th century by Kraepelin.
- There is a need for a combination of biological interventions and psychosocial therapies for optimal treatment.
