Long-term outcome following head injury.

In a perspective study of follow-up of 141 head-injured patients, neurological, behavioural, neuropsychological and psychosocial parameters of outcome were used to measure the patient's functional status for 18 months. Neurophysical sequelae including seizure disorders were seen in 29 patients. Cortical functional disturbances observed were nominal difficulties in 5 patients, perseveration in 5 patients, disturbed kinetic melodies in 9 patients, frontal acalculia in 4 patients, constructional apraxia in one patient and left side neglect in one patient. These deficits were reversed except in 13 cases. Only 32 patients (22.7%) did not suffer from any behavioural changes. The role of compensation as an aetiologic factor was found in 5 patients. Out of 94 patients in whom scores in memory test was done, 11 patients performed better than their age and education-related norms. Scores in Raven's matrices for level of intellectual performance were done in 71 patients. The score was below 25th percentile in majority (58 cases). Among 130 patients with some jobs, 56 patients (43%) were fully restored. Out of 105 married patients, 45 patients (43%) had disturbed relations after head injury. Seven patients had separation of marriage. Compared to neurological deficits, behavioural and neuropsychological impairments were more prevalent and disabling. Psychosocial outcome, particularly vocational restoration was adversely affected by behavioural changes and cognitive deficits. Need for a multidisciplinary intervention to minimise the avoidable morbidity is emphasised.
