Schizophrenia is a serious mental illness characterized by incoherent or illogical thoughts, bizarre behavior and speech, and delusions or hallucinations, such as hearing voices. Schizophrenia typically begins in early adulthood.

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), Schizophrenia spectrum and other psychotic disorders include schizophrenia, other psychotic disorders, and schizotypal (personality) disorder. They are defined by abnormalities in one or more of the following five domains:

  • Delusions
  • Hallucinations
  • Disorganized thinking (speech)
  • Grossly disorganized or abnormal motor behavior (including catatonia)
  • Negative symptoms

While no one knows the exact cause of schizophrenia, many researchers believe a combination of genetic, neurobiological, psychological and environmental factors contribute into the development of schizophrenia.
