In 53 patients, consulting for headache of different types, a pathological EEG had been observed several years ago; at this time, a neurological or medical origin of the bioelectric abnormalities could not be found. These patients (average age: 32.4 y.) were reexamined systematically after an average delay of 3 years. Generally, one observes a clear improvement or a normalization of the EEG and the clinical state. In 1/9 only of the population the EEG-abnormalities persisted. All these patients belonged to a subgroup, where certain complicating factors (cerebral-organic or general) could be specified. No brain tumour had developed meanwhile. The authors conclude: a pathological EEG in the context of headache does not obligatory indicate bad prognosis.
在53例因不同类型头痛前来咨询的患者中，数年前曾观察到病理性脑电图；当时，未发现生物电异常的神经学或医学根源。这些患者（平均年龄：32.4岁）在平均3年的间隔后接受了系统复查。一般来说，脑电图和临床状态有明显改善或恢复正常。仅在1/9的人群中脑电图异常持续存在。所有这些患者都属于一个亚组，在该亚组中可以明确某些复杂因素（脑器质性或全身性）。在此期间未发生脑肿瘤。作者得出结论：头痛情况下的病理性脑电图不一定预示预后不良。
