Study Notes

Understanding Schizophrenia: Key Factors and Cultural Considerations

People with schizophrenia have less brain tissue and cerebrospinal fluid, indicating a potential failure in development or subsequent tissue loss.
Computed tomography scans show enlarged ventricles and cortical atrophy in the brains of individuals with schizophrenia.
Positron emission tomography studies suggest diminished glucose metabolism and oxygen in the frontal cortical structures of the brain in individuals with schizophrenia.
Research consistently shows decreased brain volume and abnormal brain function in the frontal and temporal areas of individuals with schizophrenia, correlating with positive and negative signs of the disorder.
It is unknown whether frontal and temporal lobe changes in schizophrenia result from developmental failure or external factors like viruses, trauma, or immune responses.
Intrauterine influences such as poor nutrition, tobacco, alcohol, drugs, and stress are being studied as possible causes of brain pathology in schizophrenia.
Neurochemical studies consistently demonstrate alterations in neurotransmitter systems, implicating dopamine, serotonin, norepinephrine, acetylcholine, and glutamate.
Excess dopamine is a prominent theory, supported by the effect of dopamine-increasing drugs inducing psychotic reactions similar to schizophrenia and dopamine receptor-blocking drugs reducing symptoms.
Serotonin has also been identified as a leading neurochemical factor affecting schizophrenia, modulating dopamine and potentially contributing to the disorder's development.
Immunovirologic factors suggest that exposure to a virus or the body’s immune response to a virus could alter the brain physiology of individuals with schizophrenia, although few findings have validated this.
Infections in pregnant women have been considered as a possible origin of schizophrenia, with waves of the disorder occurring after influenza epidemics and higher rates of schizophrenia among children born in crowded areas in cold weather.
Cultural considerations are crucial in assessing schizophrenia symptoms, as delusional ideas and hallucinations may be accepted in some cultures, and psychotic behavior may be identified as a "culture-bound" syndrome in specific ethnic groups and countries.
