Physiogenesis and psychogenesis in the 'post-concussional syndrome'

Abstract

The aetiological factors relevant to the development of post-concussional symptoms are reviewed. From the numerous studies carried out to date, it would appear that both physiogenic and psychogenic influences are important in their genesis. However, where mild-to-moderate injuries are concerned, organic factors are chiefly relevant in the earlier stages, whereas long-continued symptoms are perpetuated by secondary neurotic developments, often of a complex nature.
