This chapter presents a narrative review of studies examining the effects of regional brain abnormalities on memory function in epilepsy. Studies were selected for review if pre-operative epilepsy patients were included, and if quantitative neuroimaging or neuropathological variables were correlated with memory test scores; thirty-three studies are described. The literature is heavily biased towards studies of long-term episodic memory in mesial temporal lobe epilepsy. Only modest and limited conclusions can be reached: the hippocampus is involved in long-term episodic memory processes, and the left hippocampus may be specialized for verbal memory processes. Further insight from this literature is limited by a number of weaknesses and confounds, such as drawing inference on the basis of qualitative associations only, failing to recognize the widespread nature of pathology, and failing to take into account the brain's adaptive processes. Improvements in study design will likely improve this field in the near future.
Keywords: regional brain abnormalities, memory function, mesial temporal lobe epilepsy, hippocampus
