Remembering to remember: prospective memory in children with epilepsy

Prospective memory, the ability to remember to perform an intended act in the future, is a complex process that involves several stages and cognitive domains. This study sought to investigate prospective memory functioning in children with idiopathic epilepsy using tasks from the Rivermead Behavioral Memory Test for Children (RBMT-C) and the Memory for Intentions Screening Test for Youth (MISTY). Performances on prospective memory task characteristics of the MISTY (i.e., cue-type, length of time delay, and response type) were also compared between and across participant groups. Healthy children (N = 26) were found to have higher overall IQ and verbal IQ scores when compared to children with epilepsy (N = 19). Group differences in prospective memory functioning were found in subtests of the RBMT-C but not on the MISTY. Lastly, while there was no significant interaction effect between the groups and MISTY task characteristics, main effects were found across participant groups; all participants performed better on event-based tasks when compared to time-based tasks and on two-minute when compared to 10-minute time delays. Overall, findings suggest potential differences in cognitive functioning, particularly in IQ and prospective memory, in children with idiopathic epilepsy, though due to differences in findings across prospective memory tasks, further research is warranted to more definitively ascertain the extent, if any, of prospective memory deficits in children with epilepsy.
