Everyday memory failures in people with epilepsy

In a series of studies, we have explored the nature of memory problems experienced by people with epilepsy. By means of a questionnaire, the first study surveyed everyday memory failures experienced by 742 people with epilepsy. Findings revealed a high level of failures that were associated with later age of onset of seizures and raised levels of anxiety and depression. A second smaller prospective study confirmed these findings and suggested that patients with epilepsy had underestimated the frequency of memory complaints when assessed retrospectively. The third study investigated the relationship between self-reported memory failures and neuropsychological test performance. A measure of verbal recall was the best predictor of reported memory failures. Again, older age of onset and mood were found to be pertinent variables in relation to memory complaints.
