Current Concepts of Memory Disorder in Epilepsy: Edging Towards a Network Account.

Abstract

A paradigm shift in contemporary epileptology has been the reframing of both epilepsy and its comorbid memory disorders as the product of diseased brain networks. The current review discusses some of the clinical and theoretical implications that stem from this shift. Some implications of a network conceptualisation of epilepsy include a need for more widespread cognitive phenotyping in epilepsy; recognition that memory disorders in epilepsy can be multi-determined, including by non-structural factors; deeper consideration given to the neurodevelopmental context in which memory problems emerge; the utility of new methods to characterise memory impairments in epilepsy; and a call for greater recognition of the close interrelationships between memory comorbidities and psychiatric symptoms in epilepsy. Memory disorder significantly worsens the quality of life of people with epilepsy, underscoring the importance to patient wellbeing of giving due consideration to the up-to-date neuropsychological practises outlined in this review.
