Catatonic Schizophrenia: This subtype is characterized by motor abnormalities, including muscle rigidity, mutism, or extreme excitement, odd or repetitive movements, and echolalia.
Undifferentiated Schizophrenia: This subtype is used when a person's symptoms do not fit neatly into one of the other subtypes. Symptoms may be present from multiple subtypes, leading to a diagnosis of undifferentiated schizophrenia.
Residual Schizophrenia: This subtype is used for individuals who have had at least one episode of schizophrenia, but currently exhibit few or no symptoms, yet still show signs of cognitive or behavioral impairment.
"Symptoms typically develop gradually, begin during young adulthood, and in many cases never become resolved."
"To be diagnosed with schizophrenia, the described symptoms need to have been present for at least six months (according to the DSM-5) or one month (according to the ICD-11)."
"About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime."
"The causes of schizophrenia may include genetic and environmental factors. Possible environmental factors include being raised in a city, childhood adversity, cannabis use during adolescence, infections, the ages of a person's mother or father, and poor nutrition during pregnancy."
"Many people with schizophrenia have other mental disorders, especially substance use disorders, depressive disorders, anxiety disorders, and obsessive–compulsive disorder."
"About half of those diagnosed with schizophrenia will have a significant improvement over the long term with no further relapses, and a small proportion of these will recover completely. The other half will have a lifelong impairment."
"Social problems such as long-term unemployment, poverty, homelessness, exploitation, and victimization are commonly correlated with schizophrenia."
"People with schizophrenia have a higher suicide rate (about 5% overall) and more physical health problems, leading to an average decrease in life expectancy by 20 to 28 years."
"The mainstay of treatment is antipsychotic medication, along with counseling, job training, and social rehabilitation."
"In situations where doctors judge that there is a risk of harm to self or others, they may impose short involuntary hospitalization. Long-term hospitalization is used on a small number of people with severe schizophrenia."
"In a network comparative meta-analysis of 15 antipsychotic drugs, clozapine was significantly more effective than all other drugs, although clozapine's heavily multimodal action may cause more side effects."
"In some countries where supportive services are limited or unavailable, long-term hospital stays are more common." Please note that the remaining questions do not have direct quotes in the given paragraph and may require additional knowledge or research:
