Neuropsychological changes after callosotomy in XXXX : a study of the short-term evolution.

@entity1 @entity5761 @entity302
With the increasing interest in callosotomy as treatment for intractable @entity302 , it seems to be important to define the neuropsychological consequences of the related surgical operation. 8 @entity1 suffering from drug-resistant seizures underwent section of the corpus callosum, 6 in the anterior part only and 2 undergoing complete two-stage commissurotomy including the posterior part. Before the callosotomy the @entity1 were studied using a cognitive, affective and behavioural battery which was repeated 15 and 90-100 days after the operation. The @entity1 with sufficient I.Q. were described in more detail using the cognitive parameters; the social and motor behaviour of @entity5761 subjects are accurately reported. No disconnection syndrome was ever observed after the partial commissurotomy while it occurred in one of the two complete callosotomies. The @entity1 showed longer reaction times and a mild impairment of linguistic, praxic, memory and motor functions in the former evaluation (15 days), but there was consistent improvement in the latter check up. At the 90-100 day follow-up the @entity5761 @entity1 responded more readily to the environmental stimulations and their postural, motor and behavioural functions were unchanged or improved, with respect to presurgical performances. The social and emotional behaviour of all the @entity1 had always improved by the time the long-term evaluation (90 days) was performed. Finally, by limiting the callosotomy to the anterior part only, the neurological and psychological consequences seem to be limited.(ABSTRACT TRUNCATED AT 250 WORDS)
