Schizophrenia is a long-term mental disorder of involving a breakdown in the relation between thought, emotion, and behavior, leading to faulty perception, inappropriate actions and feelings, withdrawal from reality and personal relationships into fantasy and delusion, and a sense of mental fragmentation. Schizophrenia is not a split or multiple-personality disorder, but a type of psychosis where a person cannot tell what is real from what is imagined.

Causes and SymptomsEdit

The exact known cause for schizophrenia is not known, but developing this illness is very likely for individuals who have a long family history of schizophrenia and have increased immune system activity, such as from inflammation or autoimmune diseases. Symptoms can include disorganized along with thought disorder, delusion, amnesia, hallucination, paranoia, incoherent speech, rapid and frenzied speaking, fatigue, impaired motor coordination, and lack of emotional response.

On Criminal MindsEdit


  • Spencer Reid's mother, Diana, is known to be suffering from schizophrenia--to a point where her husband left her to raise their son alone (among other reasons) until she would later be committed for her increasing condition.
  • Bill Robbins, the father of twin killers Wallace Hines and Jesse Gentry, had increasing schizophrenia that would later strain his relationship with their mother Carla and limit his ability to father the son he had left. He would later play a small but important role in identifying one of his sons.


  • Like Diana Reid, Ted Bryar was a smart and educated person but suffered from schizophrenia. His mental illness would later cause him to snap and suffer from a psychotic episode inside a moving train. He would later kill a security guard and held five people hostage, including SSA Elle Greenaway, all while being advised by his imaginary friend Leo.
  • Marvin Doyle's delusions that stemmed from his schizophrenia would leave him to believe that the criminals he's seen that were acquitted of their crimes were guilty, leaving him to have to punish them. This motivated his killing spree.
  • After the death of his mother (possibly at his hands), Rhett Walden's schizophrenia would have him believe his mother was still alive in a hallucination. His "mother" would later help him abduct young women to help re-enact scenes from his mother's movie to satisfy his delusions.
  • Ben Foster's schizophrenia would lead him to have hallucinations, which would leave his mother to order an exorcism as she believed he was possessed. His increasing delusional nature will lead him to drive his kills.
  • After the murder of his mother, who helped with his medication, schizophrenic killer Danny Lee Stokes abducted the ex-wife and daughter of the criminal he held responsible and killed them. Later suffering from hallucinations of the two victims, he would start a killing spree in search of his mother's murderer while killing those who performed immoral acts in his search.


  • Sylvia Seegrist is a woman suffering from paranoid schizophrenia who, on the Halloween of 1985, killed three people and wounded an additional seven in a shooting rampage at the Springfield Mall in Springfield, PA.
  • Ralph Tortorici was a paranoid schizophrenic who took 35+ hostages and injured one at the State University of New York at Albany on December 14, 1994.
  • Peter Sutcliffe's schizophrenia would have him claim that God was telling him to find and kill the prostitutes he murdered.
