Evolution of psychological disorders following head injury including memory and other cognitive disorders are common. The best known are psychiatric disturbances of various kinds after lesions of the frontal lobes. Cognitive, behavioural and emotional disorders are not usually seen in patients with bilateral temporal lesions. In our Department of Neurotraumatology we have observed 4 patients with posttraumatic lesions localized bitemporally. They developed Kluver-Bucy syndrome-rarity in human pathology-combined with three or more of the following symptoms and signs: increased oral activity, hypersexuality, hypermetamorphosis, memory disorders, placidity, loss of people recognition, bulimia. Several symptoms responded dramatically to carbamazepine. We conclude that it may be a useful agent in the treatment of this unusual syndrome.

Nine cases of posttraumatic primary brain stem haematoma are described. All cases presented ocular and vegetative symptoms. Hyperextension was regarded as the most likely mechanism of injury. All patients were treated conservatively; half of them with a good outcome.
