Document Summary
Paranoid schizophrenia is dominated by delusions of persecution, along with delusions of grandeur. People come to believe that they have many enemies who want to harass them. To make sense of their persecution, they often develop delusions of grandeur that make themselves think they are important people that the world is after. Catatonic schizophrenia is marked by striking motor disturbances, ranging from muscular rigidity to random motor activity. Not very common and its prevalence seems to be declining. In disorganized schizophrenia, a particularly severe deterioration of adaptive behavior is seen. People that cannot be placed into any of the 3 previous categories are said to have undifferentiated schizophrenia, which is marked by idiosyncratic mixtures of schizophrenic symptoms. The new scheme of sub-dividing schizophrenia categories is based on the predominance of negative versus positive symptoms. Negative symptoms involves behavioral deficits, such as flattened emotions, social withdrawal, apathy, impaired attention, and poverty of speech.
