Seizures are fairly common in those with intellectual disabilities. In order to treat these seizures, antiepileptic drugs (AEDs) are often used and in many cases are effective. However, these medications often create a variety of associated side effects. In order to monitor these side effects, measures such as the SEIZES-B have been used. While many side effects have been found to occur with the use of AEDs, research has not explored if certain side effects are more likely to co-occur. For the current study, 281 people with intellectual disability were administered the SEIZES-B to monitor side effects associated with AEDs. Correlations between side effect subscales were then computed. Several subscales were found to be significantly correlated: hepatic disturbance with dermatological changes and cognitive disturbance; respiratory disturbance with dermatological changes, sedation, and electrolyte disturbance; and cognitive disturbance with sedation and dermatological disturbance. Possible implications of these findings are discussed. (Contains 2 tables.)
