Schizophrenia is a mental disorder characterized by abnormal social behavior and failure to understand reality.[2] Common symptoms include false beliefs, unclear or confused thinking, hearing voices that others do not, reduced social engagement and emotional expression, and a lack of motivation.[2][3] People with schizophrenia often have additional mental health problems such as anxiety, depressive, or substance-use disorders.[11] Symptoms typically come on gradually, begin in young adulthood, and last a long time.[3][5]
