Abstract

Benign Epilepsy with centrotemporal spikes (BECTS) is considered a benign type of epilepsy; nevertheless a significant number of children present clear and heterogeneous cognitive deficits such as memory disturbances. Thus far, evidence about memory impairment has been less than conclusive. To clarify the quality of memory functioning in BECTS children, an analysis of existing findings has been conducted trying to identify the type of memory deficits and their underlying factors. Short- and long-term declarative memory are impaired in BECTS children, with both verbal and non-verbal material; co-occurrence of attentional, linguistic and behavioral disturbances is reported. In children with continuous spikes and waves during the slow-wave sleep pattern the normal downscaling of slow-wave activity is absent, disrupting plastic brain processes of sleep-related memory consolidation. In BECTS children, NREM sleep interictal epileptiform discharges (IED) may interfere in the dialogue between temporal and frontal cortex, causing declarative memory deficits: the role of NREM sleep IED acquires a special importance, leading to methodological guidance and suggesting aims for future researches in the field of childhood neuroscience.
