Accuracy of self-reported neuropsychological functioning in individuals with epileptic or psychogenic nonepileptic seizures

The aim of this study was to determine the degree to which subjective ratings of neurocognitive ability accurately reflect objectively measured neuropsychological functioning in patients diagnosed with epileptic (ES, n = 45) or psychogenic nonepileptic (PNES; n = 37) seizures. Patients received a battery of neuropsychological tests, measures of current mood state, and the Quality of Life In Epilepsy - 89 questionnaire. Results indicated that subjective ratings of neuropsychological functioning were only partially accurate within each group. Patients with ES accurately rated their memory function, but overestimated language and attention abilities. Patients with PNES accurately rated attention, but underestimated memory and overestimated language. In both groups, poorer self-reported neurocognitive functioning was strongly related to poorer mood state; however, mood state did not predict objectively measured neurocognitive abilities. Given the inaccuracies that exist in patient self-report, results highlight the importance of a comprehensive neuropsychological assessment when evaluating the neurocognitive status of individuals with seizures.
