A follow-up study of patients hospitalized after minor head injury

Abstract

Minor head injury accounts for 95% of all head injury. In this study 62 patients, hospitalized after minor head injury, were assessed within 48 h, and invited to attend for review and retesting 3 months later. Thirty-five patients were followed up in this way and 11 more were interviewed over the telephone. There was significant improvement on all psychometric tests between initial evaluation and follow-up. Between 51% and 86% reported troublesome late post-concussional symptoms, of which headaches and tiredness were the most frequently reported symptoms. Length of post-traumatic amnesia (PTA) was related to severity of symptoms. Clinical levels of anxiety and stress were noted in approximately one-third of the whole group; 95 % of the group had returned to work by 3 months with a mean absence rate of 9·4 days. The therapeutic implications of these results are discussed.
