[Intelligence of hemiplegic children: an association with epilepsy and the laterality of the lesion].

We studied thirty-one children with hemiplegia to elucidate the relationship of intelligence, the laterality of a lesion, and epilepsy, in these children. We investigated the influences of the age at the onset of the seizures, the number of anti-convulsants, and the duration of medication, on the DQ/FIQ. The results indicated a significantly higher DQ/FIQ and VIQ for right hemiplegic children than for left hemiplegic children. But the PIQ of the patients with either a left or right hemiplegia was not significantly different. A significantly higher DQ/FIQ, VIQ, and PIQ was also revealed for the children without epilepsy. In addition, there was also a tendency that the DQ/FIQ of children who suffered from epilepsy before the age of one year was lower than that of children who suffered from epilepsy after the age of one year. The present results provide evidence which supports the crowding hypothesis.
