Identification of neuropsychological deficits in epilepsy using the Luria-Nebraska Neuropsychological Battery: a replication attempt.

Using the Luria-Nebraska Neuropsychological Battery (LNNB), Berg and Golden (1981) assessed 40 patients with epilepsy and reported a hit rate of 77.3% for idiopathic epilepsy and 88.9% for symptomatic epilepsy (82.5% overall). The purpose of this investigation was to attempt to replicate their important findings. A consecutive series of 31 patients with epilepsy was administered the LNNB and we obtained a hit rate of 47% for idiopathic epilepsy and 30% for symptomatic epilepsy (41% overall). Four possible methodological reasons for these disparate findings were offered.
