title: Recovery of communicative functions after prolonged traumatic coma.
abstract: Fifteen patients with prolonged coma after craniocerebral injury were observed for a year or more, and their communicative functions were evaluated. Nine of them showed a considerable degree of recovery, while 6 remained in a vegative state. Of the 9 with recovery, 6 showed complete recovery of semantic functions, while 3 remained with aphasic deficits. Eight out of these 9 remained dysarthric. Communicative recovery began as late as 5.7 months after injury, and it roughly paralleled recovery in locomotion and A.D.L. Restlessness and sweating were favorable prognostic factors. Excessive salivation, snout reflex, corneomandibular reflex, retractory nystagmus and stereotypic movements were unfavorable. The 8 patients who remained dysarthric showed marked diminution of their expiratory and inspiratory reserves, and of their forced vital capacity.
