Cerebral atrophy. An immunological disorder?

Abstract

Patients with cerebral atrophy of unknown origin, patients with nuclear forms of schizophrenia or neurosis, and normal subjects were skin-tested with human brain and liver proteins. The frequency of positive delayed skin-sensitivity reactions to brain proteins was significantly higher in the cerebral-atrophy group than in other groups, thus suggesting a correlation between cerebral atrophy and cell-mediated immunity.
