A case for changing the way schizophrenia is conceptualised, using a questionnaire to relatives

In view of dissatisfaction among philosophers and many doctors with the DSM III criteria for schizophrenia a new conceptualization is needed. Recent research results showing the complex influences on the development and functions of the brain suggest that the primary problem is a reduced capacity for information processing and not the more obvious symptoms of acute episodes. An analysis of a questionnaire to relatives (members of the National Schizophrenia Fellowship) has been used to illustrate how data from relatives can provide useful indicators of some of the factors such as possible metabolic abnormalities and immune system deficiencies which may contribute to this problem. It is suggested that a broad data-base is needed to study such contributory factors and point the way to forms of treatment which might make lower levels of maintenance neuroleptic medication possible.
