Schizophrenia is classified as a mental disorder which can be described by abnormal behavior and a decreased ability to understand the reality which can also lead to difficulty with speech. With many different cases, other symptoms can include hallucinations, confused thinking, and even hearing voices that do not exist. The symptoms usually reduce social engagement and proper emotional expressions, and a lack of motivation to do normal daily activities.
Over a long period of research, the main causes of schizophrenia include environmental and genetic factors. Environmental factors can include living too close to the city or factories, drug use during adolescence, and possibly poor nutrition during pregnancy. Genetic factors can also play a role in causing a variety of common and rare genetic variants.
Treatment includes proper medication and counseling.
