NONEPILEPTIC EVENTS IN NORMAL AND NEUROLOGICALLY HANDICAPPED-CHILDREN - A VIDEO-EEG STUDY

Nonepileptic episodic phenomena are reported in 27 of 124 children (21.8%) who had video-electroencephalographic studies performed. Mean age was 7.4 years (S.D.: 6.0; range: 0.1-19). Nineteen (70%) were neurologically impaired (Group 1) and 8 (30%) neurologically normal (Group 2). The final diagnoses included movement sequences (48%), conversion disorder (22%), behavioral staring (18%), sleep disorder (11%), behavioral episodes (8%), and central apnea (8%). In Group 1, abnormal movements (58%) and staring (26%) were most common; conversion disorder (62.5%) was most common in Group 2. Unnecessary medication therapy was prevented in many children. Video-electroencephalography is valuable in preventing over-medication and misdiagnosis.
