This is a description of the psychodynamics of a posttraumatic syndrome—following a head injury which apparently left no permanent organic sequelæ—gleaned from the first seven weeks of psychoanalysis. This analysis revealed that the patient had been suffering from an underlying obsessional neurosis since childhood, due in part to a regression following an operation on his mother's genital. The trauma itself brought about a temporary organic frontal lobe

impairment, and the analytic findings seemed to indicate that this impairment acted as does leucotomy: it resulted in a disinhibition allowing a 'temporary advance from pregenital to genital activity'—a reversal of the original regression. When this genital activity led the patient into a personal relationship with a woman which he could not maintain, his neurosis burst forth. Rosenberg has set down an excellent description of the psychodynamics—which included powerful paranoid trends—as they appeared in the transference.
