Relationship of Schizophrenia to the Environment

Abstract

Attention was first drawn to the importance of this topic by Schneider (1957) when he proposed that some of his first-rank symptoms could be grouped together under the concept of ‘permeability’ of the barrier between the individual and his/her environment — the ‘loss of ego boundaries’. Similarly, in a recent series of papers (Strauss et al, 1987), the essence of schizophrenia was conceptualised in the processes of interaction between biology, behaviour, and environment. The two main syndromes — acute and chronic — can each be precipitated or made worse by environmental factors, and although most patients with the negative syndrome appear to show some irreducible impairment, poverty of the social environment has been found to worsen their condition, while on the other hand, a moderate degree of social stimulation promotes relative improvement (Wing, 1987).
