对正常儿童的脑电图研究,已有许多报告.由于检查人数、年龄和方法学的不一致,故关于正常儿童中癫癎样脑电图型的发生率,他们的结论不同.本文研究采用以前从未有过的人数,神经正常并无癫癎发作史的儿童3,726人,男性1,988人,女性1,738人,年龄6至13岁,并按年龄分组进行纵向追踪观察.在清醒安静和过度换气中描记脑电图.其中131人(3.54%)发现癫癎样脑电图型,包括每秒三次棘慢波放电(4例),多棘慢波综合(37例)中颞棘波(50例),中央区或顶叶棘波(27例),枕叶的棘波(2例)和多灶棘波(11例).男性异常发生率较高.这些异常的家族发生也有些迹象.脑电图异常的一半人有行为问题和/或轻度精神运动能力障碍.进行纵向追踪8-9年,这些脑电异常表现自发性消失,通常在学龄期,最迟到青春期.仅7例发生临床癫癎发作(1例失神发作、1例双侧肌阵挛发作,3例
There have been many reports of EEG studies in normal children, and their conclusions are different with regard to the incidence of epileptiform EEG in normal children due to inconsistencies in the number of examinations, age, and methodology. In this study, 3,726 children with normal history of absence of epilepsy, 1,988 males and 1,738 females, aged 6 to 13 years old, and followed longitudinally by age grouping In consciously quiet and hyperventilation EEGs were found in 131 (3.54%) patients, including epileptiform EEG patterns including three spikes and four waves per second (n = 4), multiple spikes and waves (n = 37) (27 cases) in the central region or the parietal lobe, 2 cases of spine waves in the occipital lobe, and 11 cases of multi-focal spikes (11 cases) .There was a high incidence of abnormalities in men.These abnormal families also showed some signs. Half of EEG abnormalities have behavioral problems and / or mild mental dysfunction. These longitudinal abnormalities disappear spontaneously during the 8 to 9 years of longitudinal follow-up, usually in school age and late in adolescence. Clinical epileptic seizures (1 case of absence seizures, 1 case of bilateral myoclonus seizures, 3 cases
