What does it mean when the doctor says someone has positive symptoms of schizophrenia?

The positive symptoms of schizophrenia usually reflect an excess of altered normal behaviors. These  signs of schizophrenia include 1) delusions which are not based on reality but are usually false perceptions- seeing things that are not physically present 2) auditory hallucinations involve hearing things that no one else can hear, and in most cases the voices are persecutory or religious 3) thought disorder which creates difficulty in speaking or organizing thoughts in a lucid form and 4) disorganized behavior which may present as unpredictable childish behavior, anger or irritability.
