Temporal lobe epilepsies (TLE) are associated with material-specific memory deficits depending on the side of seizure origin. However, while verbal memory deficits have been consistently reported in patients with left-sided TLE, the relationship between visual memory deficits and right-sided TLE is more complex. Here, we review factors that influence the pattern of lateralization and the nature of visual memory impairments in TLE and discuss the possible relationship between these deficits and perceptual impairments in TLE patients.
