Schizophrenia
A psychotic disorder that must include the presence of delusional thoughts and hallucinations. These delusional thoughts often manifest themselves as delusions of grandeur (the belief that you are a figure of much greater stature than you really are). The hallucinations may be auditory, visual, olfactory, or tactile. The most commonly experienced hallucination by individuals who have schizophrenia is auditory.
Catatonic Schizophrenia
Involves a severe disturbance in movement. This may include moments of dramatic movement, which is often repetitive (catatonic excitement). More often, the person experiences a severe limitation of movement, often to the point of a kind of waxy flexibility (catalepsy).
Disorganized Schizophrenia
Includes a disorganization of thought process, which illustrates itself through disorganized behaviour and speech. Often, hallucinations are much less predominant with this sub-type.
Paranoid Schizophrenia
Cognitive function usually remains intact, while delusions and hallucinations regarding persecution and conspiracy are very prevalent.
Residual Schizophrenia
This diagnosis is offered when a person no longer displays prominent symptoms. They may continue to experience the symptoms, but to a much lesser degree.
