Positive symptoms of schizophrenia

Schizophrenia causes two types of symptoms: negative and positive. "Positive" does not mean "good." Positive symptoms are things "added" or "new" to your personality or how you experience life because of schizophrenia. The most common positive symptoms of schizophrenia include:

  • Hallucinations , especially hearing voices. The hallucinations seem real to the person having them. Hallucinations can involve sight, hearing, taste, smell, and/or touch.
  • Delusions , which means you believe something that cannot be proven or continue to believe something that has been proven to be false or wrong. A common delusion is to believe you are an important historical or political person, or that there is poison in your food.
  • Confused and disorganized speech and behavior. These include:
    • Making no sense when talking or easily getting off the subject of the conversation.
    • Dressing oddly, such as wearing many shirts at one time or wearing winter hats and gloves during the summer. It is also possible to exhibit socially inappropriate behavior, such as urinating in public.

Positive signs of schizophrenia usually can be reduced or prevented with medicines.
