Abstract
We report results of clinical examinations, computed tomography, quantitative electroencepha‐lography (QEEG), and cerebral blood flow measurements performed on a series of 56 consecutive brain injury patients including 15 alcohol abusers and 41 non‐alcoholic subjects. Greater volumes of intra‐cranial haemorrhage were noted in the alcoholics for a similar severity of injury and local brain atrophy became more pronounced in them during a follow‐up of 1 year. After this time, the third ventricle width, distance between frontal horns, the sum of lateral ventricle dimensions and cortical sulci were all markedly larger in the alcoholics. The QEEG results also indicated a weaker improvement in the alcoholics. The cerebral blood flow at the site of the injury was initially slow in the alcoholics when compared to the contrala‐teral region of the other hemisphere, although these differences disappeared during the follow‐up. Permanent occupational disability was also found to be associated with pretraumatic alcohol abuse.The findings indicate that ethanol abuse is not only commonly associated with cerebral trauma but is also a risk factor for a more severe brain damage following the injury.
