The pathomechanism of the migraine aura remains unclear. The most probable cause of the aura is cortical spreading depression with associated hypoperfusion. Both the cortical spreading depression and hypoperfusion begin in the occipital lobes and spread forward slowly (2-3 mm/min) in a wave-like mode along the brain convolutions and cross territories of brain arteries. We present a 24-year-old female patient with a combination of aura symptoms. Each migraine attack began with a bright scintillating zig-zag, which crossed the visual field. It was followed by left sided hemiparesthesiae marching from the face to the hand. The last symptom of aura was motor aphasia. Later a unilateral, pulsating headache developed with associated photo- and phonophobia. The stable pattern and duration of aura symptoms in the presented case suggest that the cortical spreading depression plays an important role in the pathomechanism of migraine with aura.
偏头痛先兆的发病机制尚不清楚。先兆最可能的原因是伴有相关灌注不足的皮质扩散性抑制。皮质扩散性抑制和灌注不足均始于枕叶,并以波浪状模式沿脑回缓慢向前扩散(2-3毫米/分钟),跨越脑动脉的供血区域。我们报告一名24岁女性患者,有先兆症状组合。每次偏头痛发作开始时都有明亮的闪烁之字形,穿过视野。随后是从面部到手的左侧半身感觉异常。先兆的最后一个症状是运动性失语。后来出现了单侧搏动性头痛,并伴有畏光和畏声。该病例中先兆症状的稳定模式和持续时间表明,皮质扩散性抑制在有先兆偏头痛的发病机制中起重要作用。
