Frontal accentuated intermittent rhythmic delta activity (FIRDA, left) and generalized 3 Hz polyspike wave complexes (middle) in the bipolar longitudinal rows (7 microV/mm, 0.3 s, 70 Hz). The findings of the independent component analysis are presented in the right picture [the following four relevant components were found, left: activity traces, with examples of atypical activity cut from the clinical electroencephalography and appended at the dotted lines. Right: topographies, nose upward, negative (direction opposite of activity trace) blue, positive (direction same as activity trace) red. Right (component 3) and left (component 5) frontal activity show most prominent ~2.6 Hz bursts. Higher frequency activity frontocentral (component 2) and occipital (alpha component 7) are partially related].

Taken together, the immunological alterations were compatible with the previously known ulcerative colitis. The electrophysiological findings (Figure 1) would be compatible with primary (idiopathic) generalized epilepsy; however, the history for epileptic seizures including absences and myoclonic jerks was negative.
