Abstract
Childhood epilepsy can be frequently associated with impaired cognitive functioning. Previous research has suggested an increased risk of cognitive impairment that may be related to the etiology, the electro-clinical pattern and the load of anti-seizure medications (ASMs). The aim of this study was to evaluate the impact of different clinical features on the global intellectual functioning in a cohort of children and adolescents with epilepsy. We studied eighty patients diagnosed and followed in a tertiary care center. These factors were examined: 1. Etiology of epileptic syndrome; 2. Type of seizure; 3. Number of ASMs; 4. Seizure frequency; 5. Age at seizure onset; 6. Total duration of epilepsy; and 7. Active duration of epilepsy. Multiple regression analysis showed that the etiology and the total duration of epilepsy were the best indicators of intellectual functioning. The present data indicate that children with symptomatic epilepsy (SE) have lower IQ scores (M = 63.5), while children with self-limited focal epilepsy and generalized idiopathic epilepsy, i.e. age-related epileptic syndromes (ARES), have a higher IQ (M = 100.0; p < 0.01). Children with epilepsy of unknown etiology (UEE) (M = 75.1; p < 0.05) are positioned at an intermediate level between the SE and the ARES group (p < 0.01). Increased duration of epilepsy was associated with decreased intellectual functioning. In conclusion, knowledge about the risks associated with etiologic factors and the duration of the disease may guide the definition of optimal neuropsychological rehabilitation strategies.
