Neuroleptic-induced deficit syndrome. Historical introduction.

Abstract

The treatment of psychotic illness has long been inextricably associated with society's view in general on social deviance. In medieval times, psychotic individuals were contained within the community, a situation which still prevails in many developing countries. Aggregation of such patients in asylums followed the increasing industrialization of communities in the nineteenth century, when the ability of the disadvantaged of all kinds to survive was greatly jeopardized. The twentieth century has seen a gradual reversal of this process, as attitudes towards mentally ill people have become a little more enlightened and liberal. However, the swing against the great lunatic asylums of the last century has proceeded at such an administrative rate that our patients are again in danger of succumbing medically and economically within our communities. It is common to see desperately poor and damaged psychotic individuals on our streets. The advent of neuroleptics was a major factor in the change from a custodial to an ostensibly rehabilitative approach in the treatment of schizophrenia. However, classic neuroleptics have a long list of well-recognized side effects such as affective and cognitive impairment that lead to poor treatment compliance, psychiatric relapse and social decompensation, the state of affairs of our street psychotics. Treatments that lessen the probability of this unfortunate process are desperately needed. The introduction of new neuroleptic drugs with favourable side effect profiles is to be welcomed as a major step in increasing the quality of life of our patients, both in hospital and functioning in the community.
