Q&A

• What are the effective treatments for schizophrenia?

  Effective treatments for psychosis include medication, cognitive-behavioral therapy, and electroconvulsive therapy. Early intervention is crucial, as untreated psychosis can become ingrained. Stigma hinders help-seeking, but education can reduce stigma and improve access to treatment.

• What are the side effects of antipsychotic drugs?

  Newer antipsychotic drugs can have side effects like weight gain, and uncertainty exists regarding whether neural tissue loss in schizophrenia is due to the disease itself or drug-induced suppression of signaling.

• How do antipsychotic drugs work?

  Antipsychotic drugs target dopamine receptors to relieve symptoms of schizophrenia and may also target other neurotransmitters like serotonin.

• What are the causes of schizophrenia?

  The cause of schizophrenia is likely a combination of genetic and environmental risk factors. It has strong genetic links, and exposure to certain viruses in early infancy is cited as an environmental factor.

• At what age does schizophrenia typically onset?

  Schizophrenia typically onsets in the late teens or early twenties, featuring the onset of psychosis. For women, it may onset in the late twenties or early thirties.

• What is schizophrenia?

  Schizophrenia is a complex and stigmatized illness that is considered a syndrome with varied symptoms and causes. It typically features positive symptoms like delusions and hallucinations, negative symptoms like reduced motivation and emotion expression, and cognitive symptoms.

• 00:06 Schizophrenia is a complex and often misunderstood illness with varied symptoms and causes. Diagnosis typically occurs after the onset of psychosis in late teens or early twenties.
• 00:55 Schizophrenia typically onsets in the late twenties or early thirties for women, featuring positive symptoms like delusions and hallucinations, negative symptoms like reduced motivation and emotion expression, and cognitive symptoms. It is a disruption of thought processes rather than the manifestation of multiple personalities.
• 01:48 Schizophrenia is likely caused by a combination of genetic and environmental factors. Genetic predisposition is strong, with close relatives having a higher likelihood of developing the illness.
• 02:37 Genetic risk and environmental factors can impact the development of schizophrenia. Antipsychotic drugs target dopamine receptors to alleviate symptoms.
• 03:28 Newer antipsychotic drugs target multiple neurotransmitters to address negative symptoms of schizophrenia, but can have side effects like weight gain.
• 04:18 Effective treatments for psychosis include medication, cognitive-behavioral therapy, and electroconvulsive therapy. Early intervention is crucial, as untreated psychosis can become ingrained. Stigma hinders help-seeking, but education can reduce stigma and improve access to treatment.
