ABSTRACT

INTRODUCTION Multiple factors underlie the cognitive changes associated with epilepsy, including the effect of antiepileptic drug (AED) therapy itself. The use of AEDs in the management of epilepsy requires an ongoing risk-benefit analysis that attempts to maximize seizure control while minimizing adverse cognitive side-effects.

AIM This review focuses on the global and specific cognitive effects of the classic and the new AEDs. DEVELOPMENT. All of the established AEDs can produce cognitive side effects, which are increased with polypharmacy and with increasing dosage and anticonvulsant blood levels. The main disorders are a diminished reaction and information processing time with alterations affecting memory, attention and language. Further, there is much debate concerning the existence and clinical importance of differential AED cognitive side effects and a large portion of the literature examining the comparative cognitive effects of AEDs is limited by inadequate study designs.

CONCLUSIONS Cognitive side effects of antiepileptic drugs are common and can negatively affect tolerability, compliance, and long-term retention of the treatment. The role of cognitive side effects should be kept in proper perspective when choosing AED therapy. It is important to be able to recognize early these effects and to put them into perspective as to how they affect our patients KeywordsAntiepileptic drugs Child neuropsychology Cognitive Epilepsy Learning disorder Side effects CategoriesEpilepsias y síndromes epilépticos Neuropsicología
