Schizophrenia

Schizophrenia was a severe mental illness characterized by delusions and hallucinations. The hallucinations were often auditory, manifesting as voices in the head. Some schizophrenics would have visual hallucinations, as exemplified by the Aleena Jedi Kazdan Paratus who believed that his junk constructs of the Jedi Council were actual living individuals.

Schizophrenics would sometimes exhibit violent behavior. Victor Jun, an Alliance recruiter, would often act on the orders given to him by the voices in his head, which sometimes involved murder.

The Gand findsman Zuckuss also suffered from this condition.
