At one year followup, four (2.9%) patients had a severe disability, 35 (25.5%) had a moderate disability and 95 (69.3%) had no disability according to the Glasgow outcome scale. A slightly higher proportion (33.3%, n=45) showed disability according to the Edinburgh rehabilitation status scale. Thirty-one patients (23.1%) scored < 24 in the mini mental state examination. These were mostly patients over the age of 65. Twenty-three patients (17.2%) were diagnosed as psychiatric patients according to the clinical interview schedule-revised scale. Seventy-four (55.2%) patients showed one of the symptoms of postconcussional syndrome. The most commonly shown neurobehavioral problems were irritability (30%), sleep disturbance (29%), and impatience (27%). One year after a minor head injury, a substantial proportion of patients showed neuropsychiatric sequelae. |
