[Prognostic evaluation of severe head injuries in children].

In 34 children overcoming a severe head injury (coma greater than 1 d, mean: 10 d), the follow-up (mean: 25 m) has been correlated with several data. 1) The quality of life, according to a 3 grade-score, is mostly dependent upon the degree of neuropsychological sequelae. By decreasing frequency were noted disturbances of: memory, intelligence (the most significantly correlated with the quality of life), attention, rapidity of performances, behaviour, visuoconstructive activities. Most often several disturbances were associated, but without systematization. 2) Correlations between general outcome and early findings: a coma greater than 10 d, a subdural collection on the CT scan at 2-6 weeks have a pejorative meaning. Age does not appear to be relevant. 3) In a sequential study of neuropsychological functions, an early evaluation is poorly predictive, except in case of rapid normalization. Evaluation at 6 months gives a good picture of the outcome. Sectorial improvements can occur beyond the 1st year but do not appear to modify dramatically the general outcome.
