Possible link between ALF and sleepA number of observations suggest a relationship between ALF and sleep.There is a widely documented reciprocal relationship between sleep and epilepsy. Structural brain abnormalities have been identified in patients with ALF (e.g., Butler etal., 2009, Butler etal., 2013andMalmgren and Thom, 2012), but these have not been found to correlate with ALF severity. doi: 10.1016/j.smrv.2008.08.002. Post-learning sleep enhances consolidation of declarative, procedural and emotional memories. Ideally, therefore, a neuropsychological model of memory consolidation would exhibit normal learning performance but excessively rapid forgetting. Instead, ALF may be due to an encoding abnormality that goes undetected on behavioural assessments of learning, or by a deficit in memory consolidation processes that are not sleep-dependent.KeywordsAccelerated long-term forgetting; Transient epileptic amnesia; Memory; Consolidation; Sleep1.

Slow wave sleep (SWS) particularly enhances declarative memories whereas rapid eye movement (REM) sleep preferentially supports procedural and emotional memory aspects. Memories associated with expected reward gain preferentially access to sleep-dependent consolidation.
