The Wechsler Adult Intelligence Scale--Revised (WAIS-R), the newest version of the Wechsler Scales, has had several factor analytic studies, but none have been done in a sample of seizure-disorder patients. The factor structure of the WAIS-R was examined in this study in a sample of 107 patients with various seizure disorders. The results of this study revealed the 3-factor solution, as has been reported in many previous studies. The most notable difference was the relatively greater prominence of the Freedom from Distractibility factor. These results are consistent with studies of the factor structure of previous editions of the Wechsler Scales in samples of epileptic patients. The relative prominence of the Distractibility factor could suggest that attentional factors are a more important influence on performance than in other patient groups. Further studies are needed to clarify the effect of various seizure-related variables on patterns of intelligence.

UI	MeSH Term	Description	Entries

D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D004827	Epilepsy	A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).
