New criteria for defining electroencephalogram interictal epileptiform discharges enhance diagnosis

Takeaway

  • Diagnostic accuracy for epilepsy can be improved by assessing electroencephalogram features corresponding to key International Federation of Clinical Neurophysiology criteria.

Why this matters

    These findings provide Class III evidence that International Federation of Clinical Neurophysiology criteria in sensor space and analysis in source space have high specificity and sensitivity for identification of interictal epileptiform discharges. Their implementation in clinical practice could lead to a reduction in overinterpretation of electroencephalography and misdiagnosis of epilepsy.
