ABSTRACT
This study was designed to identify the incidence of sleep complaints in 39 patients with chronic postconcussion syndrome compared to those of a control group of 27 patients with orthopedic injuries. Patients with orthopedic injuries were selected as a comparison group to control for the effects of traumatic injury or chronic pain. There were no differences in age, sex distribution, or time from injury between the patient groups. Type and frequency of sleep disturbances in a mean two-year postinjury period were evaluated. Patients with chronic postconcussion syndrome reported more difficulty in initiating and maintaining sleep at night and greater difficulty with sleepiness during the day.

A follow-up study of 265 patients treated by microsurgical techniques for ruptured intracranial aneurysms at the Department of Neurological Surgery of the Radcliffe Infirmary, Oxford from 1972 to 1977 showed that prediction of results in terms of mortality, and various measures of morbidity could be achieved by considering before operation several variables in combination. Age, systemic blood pressure on admission and before operation were the most important factors in determining outcome. Inclusion of a variable following operation-arterial spasm-was found to improve prediction somewhat. In addition, spasm was found to be the single most important factor in predicting both mortality and morbidity.
