Different types of SCHIZ0PHRENIA

There are five types of schizophrenia, each based on the kind of symptoms the person has at the time of assessment.

• Paranoid schizophrenia: The individual is preoccupied with one or more delusions or many auditory hallucinations but does not have symptoms of disorganized schizophrenia.
• Disorganized schizophrenia: Prominent symptoms are disorganized speech and behavior, as well as flat or inappropriate affect. The person does not have enough symptoms to be characterized as suffering from catatonic schizophrenia. 
• Catatonic schizophrenia: The person with this type of schizophrenia primarily has at least two of the following symptoms: difficulty moving, resistance to moving, excessive movement, abnormal movements, and/or repeating what others say or do.
• Undifferentiated schizophrenia: This is characterized by episodes of two or more of the following symptoms: delusions, hallucinations, disorganized speech or behavior, catatonic behavior or negative symptoms, but the individual does not qualify for a diagnosis of paranoid, disorganized, or catatonic type of schizophrenia.
• Residual schizophrenia: While the full-blown characteristic positive symptoms of schizophrenia (those that involve an excess of normal behavior, such as delusions, paranoia, or heightened sensitivity) are absent, the sufferer has a less severe form of the disorder or has only negative symptoms (symptoms characterized by a decrease in function, such as withdrawal, disinterest, and not speaking).
