Study Notes
Understanding Schizophrenia and Antipsychotic Drugs
- Avolition refers to a reduction or absence of motivation, hindering the ability to start or finish tasks.
- Catatonia involves remaining motionless in awkward positions for extended periods, often seen in individuals with schizophrenia.
- Diagnosis of schizophrenia spectrum disorder requires the recurrence of any two symptoms for over a month, with one being delusions, hallucinations, or disorganized thought.
- Antipsychotic drugs are used to treat schizophrenia and other psychotic symptoms in various disorders, aiding in the reduction of psychosis.
- The accidental discovery of chlorpromazine in the 1950s marked the first major breakthrough in antipsychotic drugs.
- Chlorpromazine alleviates symptoms of schizophrenia, calming agitated patients and activating emotionally blunted ones.
- Reserpine, derived from the Indian snake root plant, was initially used to treat schizophrenia but is no longer in use due to its adverse effects on blood pressure.
- The dopamine hypothesis suggests that an imbalance in dopamine levels contributes to symptoms of schizophrenia, including delusions and hallucinations.
- Antipsychotic drugs affect dopamine levels and have a high affinity for dopamine receptors, particularly the D2 receptor.
- Atypical antipsychotics, such as clozapine, are effective against schizophrenia without binding strongly to D2 receptors.
- Research on hallucinogenic drugs focuses on their effects in modeling schizophrenia symptoms and their potential use in treating psychiatric disorders.
- The two lines of study for psychedelic drugs involve modeling schizophrenia symptoms and exploring their potential for treating psychiatric disorders.
