Traumatic basal ganglia hemorrhage (TBGH) is probably secondary to rupture of lenticulostriate or anterior choroidal arteries. We evaluated 6 consecutive cases of this entity to define its clinical and pathologic dimensions. Relative frequency of TBGH was 3% (3 left, 3 right) in this acute rehabilitation population. Lesion size and associated pathology varied. Contralateral hemiparesis, present in all, recovered to varying extents, apparently related to lesion location (posterior limb, internal capsule, or midperiventricular white matter), not size. Prolonged muteness occurred in 4 of 6; these 4 patients also had severe diffuse axonal injury. Clinical findings corresponded with previously recognized subcortical hemisphere profiles. All achieved a moderate disability or good recovery rating on the Glasgow Outcome Scale. Rather than any features of the TBGH itself, duration of coma and/or associated temporal herniation predicted slower recovery and worse outcome. In conclusion, TBGH is a rare entity compatible with a favorable recovery, especially when occurring in isolation. The hemorrhage itself determines clinical signs related to particular subcortical structures involved and the side of the lesion. Overall cognitive impairment and speed and quality of recovery are more related to associated cerebral damage.

The data suggest that the presence of the lipoprotein APOE epsilon4 adversely affects rehabilitation outcome for traumatic brain injury survivors.

Emotional incontinence is a behavioural syndrome characterized by involuntary weeping, grimacing, and/or laughter. We investigated the efficacy of fluoxetine in 13 patients with emotional incontinence. All 13 patients demonstrated dramatic improvement in emotional lability within 3 to 14 days.

A chart review of dextroamphetamine treatment in 27 traumatic brain injury patients during rehabilitation therapy suggests that amphetamine treatment enhanced the recovery and functional status of 15 patients.
