一名 49 岁的女性报告了与单侧头痛相关的短暂性神经功能障碍发作。光环的一个显着特征是一段完全色盲的时期，因此视觉场景是单色的。在完全缓解之前，该发作发展为包括面部失认症和空间失认症的特征。其他暂时性神经功能障碍的发作定期发生，直至开始预防性抗偏头痛治疗。四血管脑血管造影和脑MRI均正常。参考当前的大脑定位概念讨论了这种不寻常的偏头痛先兆的可能原因。
A 49 year old woman reported an attack of transient neurological dysfunction associated with unilateral headache. A prominent feature of the aura was a period of complete achromatopsia, so that the visual scene was experienced in monochrome. The episode developed to include features of prosopagnosia and spatial agnosia before resolving completely. Other episodes of transient neurological dysfunction followed at regular intervals until prophylactic antimigrainous therapy was initiated. Four vessel cerebral angiography and MRI of the brain were normal. Possible causes of this unusual migrainous aura are discussed with reference to current concepts of cerebral localisation.
