In this type of schizophrenia, the individual has feelings of being persecuted or plotted against. Affected individuals may have grandiose (over-the-top) delusions associated with protecting themselves from the perceived plot.

The key symptoms are delusions and auditory hallucinations. Paranoid schizophrenia usually does not involve the disorganized speech and behavior that is seen in other types of schizophrenia. Patients with paranoid schizophrenia typically are tense, suspicious, guarded, and reserved.
