The aim of this study was to document the frequency and types of aura symptoms, to define the relationship between aura symptoms and to define the aura frequency in different migraine types. In 952 migraine patients, aura frequency, duration, time to headache, characteristics and percentage of headaches with aura were analysed. Thirty-eight percent of IHS 1.1-1.5 patients reported aura, 38.1% of females and 33.0% of males. Average percentage of aura occurrence with headache was 19.7% of headaches, average aura duration 27.3 min and aura was followed by headache in 10.4 min on average. Visual disturbances occurred in 92.1% and aura without visual aura was rare. Aura frequency was headache-type dependent. The highest frequency of aura was seen in the more 'full-blown' migraine attack. Visual aura is the overwhelming aura symptom. Even in patients with aura the percentage of aura with migraine attacks is limited.
本研究的目的是记录先兆症状的频率和类型，确定先兆症状之间的关系，并确定不同偏头痛类型中的先兆频率。对952例偏头痛患者的先兆频率、持续时间、头痛发作时间、特征以及伴有先兆的头痛百分比进行了分析。国际头痛协会（IHS）1.1 - 1.5型患者中38%报告有先兆，女性为38.1%，男性为33.0%。伴有头痛的先兆发作平均百分比为头痛的19.7%，先兆平均持续时间为27.3分钟，先兆发作后平均10.4分钟出现头痛。92.1%的患者出现视觉障碍，无视觉先兆的先兆情况罕见。先兆频率取决于头痛类型。在更“典型”的偏头痛发作中先兆频率最高。视觉先兆是最主要的先兆症状。即使在有先兆的患者中，伴有偏头痛发作时的先兆百分比也有限。
