This spike complex was seen in 6.4% of 2,209 routine eeg records. The complex was viewed either in occipital and temporal leads simultaneously, or only in the temporal lead. No recurring pattern appeared, even on the same record. Both unilateral and bilateral complexes were observed. The pattern was found in 10.5% of all abnormal or borderline records. Age group 11-20 years accounted for 17.9% of the observed patterns, and 25.2% of these patterns were associated with abnormal records. More than half of the records with this pattern also showed some other type of eeg abnormality. Of patients with the pattern, 42% had a history of clinical convulsions, and 40% had histories of epileptic equivalents, migraine or behavioral disturbances. In over half of the patients, no etiologic factor could be detected. The eeg pattern seems to be most frequently encountered in children and adolescents with clinical histories suggesting autonomic or visceral manifestations, headache, or behavior disturbances. The authors consider the 14 and 6 per second positive spike complex indicative of an epileptiform disorder.
