ABSTRACT

INTRODUCTION Rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes is called benign because its seizures are usually favourable and due to the spontaneous normalisation of the electroencephalogram on reaching puberty. Nevertheless, evidence has been found of the impact on cognitive development with the presence of heterogeneous cognitive deficits, especially related to persistent intercritical discharges during non-REM sleep. The aim of this study is to examine the epileptogenic networks involved in the neuropsychological disorders of this pathology. DEVELOPMENT. A common feature of the atypical developments is persistent epileptic activity during slow sleep, which plays an important role in the development of the neurocognitive deficits that are associated to this pathology. Factors such as the age at onset of the epilepsy, the onset of the atypical development, the location of the interictal discharges and the continuous epileptic activity during sleep that persists for more than two years can trigger changes in the functioning of the neurocognitive networks. This may result in deficits in the neuropsychological functions, which may even be irreversible.

CONCLUSIONS A close clinical and electroencephalographic follow-up is necessary. Moreover, formal neuropsychological studies must be conducted as of the onset of benign childhood epilepsy with centrotemporal spikes. This is even more necessary in cases in which there is an obvious atypical development in order to detect and prevent the neuropsychological deficits before they establish themselves on a definitive basis.
