Schizophrenia is a mental disorder that reduces the ability to understand unusual behavior, weird speech, and reality. Other symptoms do not include false beliefs, obscure or confused thinking, voices that reduce social engagement and emotional expression, and there is a lack of motivation. People suffering from schizophrenia often have mental health problems such as anxiety, depression, or substance use disorders. Symptoms usually come gradually, young people start in adulthood, and, in many cases, are never solved.
The major causes of schizophrenia positively include environmental and genetic factors. Potential environmental factors include being raised in a highly crowded city, use of cannabis during adolescence, some infections, age of a person's parents and poor nutrition during pregnancy. Genetic factors include various types of normal and rare genetic forms. The diagnosis is based on observed behavior, during the diagnosis of the person's experience and the report of people familiar with others, a person's culture should also be taken into account. According to 2013, there is no objective examination. Schizophrenia does not have a "split personality" or dissociation identity disorder, with situations in which it is often confused with public perception.
The mainstay of treatment is antisycotic medicine, with counseling, job training, and social rehabilitation. It is unclear whether typical or atypical antipsychotics are better or not. In those people who do not improve with other antipsychotics, cloepapinem is tried. In more serious situations where there is a risk for self or other people, recruitment to the involuntary hospital may be necessary, although the people living in the hospital are now fewer and less often than those.
Approximately 0.3% to 0.7% of people are affected by schizophrenia during their lifetime. In 2015, there were an estimated of 23.6 million cases recorded globally. Males are affected more often and experience more severe symptoms than average. Approximately 20% of people eventually do good, and some are completely cured. About 50% of life losses occur. Social problems, such as long-term unemployment, poverty, and homelessness are common. Compared to the general population, the average life expectancy of people with disorders is 10-25 years short. This is the result of increased physical health problems and high suicide rates (about 5%). In 2015, around 17,000 people worldwide died due to schizophrenia behavior.
