  • Benign Familial Infantile Epilepsy Type 4

    Ictal EEG may be normal but more commonly shows bifrontal, high-voltage sharp and slow waves or low-ampli tude, fast frontal activity with the clinical seizure.[neupsykey.com] The EEG examination showed diffuse abnormal background activity, with sporadic isolated bilateral sharp waves over the occipital regions (a).[onlinelibrary.wiley.com] The abnormal EEG findings that are most likely to correlate with clinical seizures include spikes or sharp waves, with or without concomitant slow waves, that are generalized[aafp.org]
