This is a report of first hand observations on soldiers during intensive and severe combat. Fabing finds that blast injuries produce a retrograde amnesia for the sound of the explosion and an anterograde unconsciousness of variable length. The unconsciousness is seldom characterized by coma but is marked by dissociated, aimless behavior. Upon the return of consciousness there is tinnitus, headache, and diffuse anxiety symptoms. Organic neurological findings are negative. When the amnesia is overcome there is usually a dramatic relief of all symptoms. Hypnosis and intravenous pentothal were used very efficaciously. Fabing presents an abundance of case histories and a very clear description of the techniques employed.
