The Relevance of Tissue Characterization in Brain C.A.T. Scans to Psychosomatic Diagnosis

  • K. I. Pearce
Conference paper


Many other papers in this symposium have addressed more directly the manner in which the term psychosomatic diagnosis has changed over the years, and seems likely to change further in the future. In this paper I shall use the general concept of psychosomatic diagnosis to include those diagnoses where the symptomatology is essentially psychological or behavioural, and the cause is thought to lie within some sort of dysfunction of the brain. It was in the past convenient to separate functional disorders of the brain from structural disorders of the brain. This division no longer has any meaning since disorders like schizophrenia which were previously seen as being “functional” have (at least in a significant proportion of cases) been associated with abnormalities of structure in the brain, detected by Computer Assisted Tomography (C.A.T.) scanning (Weinberger, 1983)1. Since this is equally true of the affective psychoses (Pearlson et al., 1981)2 it would not be unfair to comment that the advent of brain C.A.T. scanning has turned our ideas about etiology upside down.
