Subclaims¶

q2 i? Among 40 ADHD children, 15 (37.5%) had abnormal non-epileptiform EEG activity and 5 (15%) had epileptiform activity, with the inattentive subtype showing the highest proportion of epileptiform activity (4 of 9, 44.4%). → Mohamed A. Ahmed 2014

q2 · i? · associational · r1

Descriptive EEG classification (normal, abnormal non-epileptiform, epileptiform) by a professor of neurology in two sessions. By subtype, epileptiform activity occurred in 44.4% of inattentive, 3.6% of combined and 33.3% of hyperactive-impulsive children (Fig. 2).

"Nineteen (47.5%) of the studied children had normal EEG, 15 (37.5%) children with abnormal non-epileptiform activity and five (15%) children with epileptiform activity."
