Abstract
— Three scales, assessing the degree of brain impairment after severe blunt head injury in neurophysical and neuropsychological functions as well as overall organic functioning, are described. A consecutive series of 100 severe blunt head injured patients was followed up 6 years post-trauma and the scales were used to measure the residual impairments and determine the level of recovery for 82 subjects in the series. No subject made a complete neurophysical and neuropsychological recovery, 92% of the series was classified as suffering clinically significant impairments and in half the series the moderate or severe impairments were consistent with a poor level of recovery. The impairments of a large proportion (42%) of the series, however, were classified as mild. Although most subjects demonstrated impairments in both neurophysical and neuropsychological functions, 43% of the series suffered isolated impairments in either the neurophysical or neuropsychological areas. There was strong agreement between the overall organic impairment profile and the subjects’ classifications on the Glasgow Outcome Scale.
