EEG in ulcerative colitis.

Electroencephalographic tracings of 50 patients with ulcerative colitis (UC) were compared with those of 75 controls. In the UC patients a 24 % incidence of abnormal tracings was found as compared with an 8 % incidence in the controls. A higher incidence of abnormal electroencephalograms was found among active cases of UC than among those in remission. The meaning of these results is not yet clear.
