Interictal epileptiform discharges can help predict the risk of developing epilepsy and may also aid in diagnosing specific epilepsy types or syndromes. However, mimics of epileptiform discharges—such as benign variants, sharp transients, artifacts, or normal sleep features—must be carefully distinguished. This chapter reviews the definitions, specificity, sensitivity, and mimics of interictal epileptiform discharges in focal epilepsy.

摘要

Interictal epileptiform discharges can help predict the risk of developing epilepsy and may also aid in diagnosing specific epilepsy types or syndromes. However, mimics of epileptiform discharges—such as benign variants, sharp transients, artifacts, or normal sleep features—must be carefully distinguished. This chapter reviews the definitions, specificity, sensitivity, and mimics of interictal epileptiform discharges in focal epilepsy.
