The clinical aspects of migraine aura

Migraine aura is experienced by less than one quarter of migraine patients. Some sufferers undergo “aura”- visual symptoms example geometric patterns, flashing lights or possibly a shimmering effect (kind of like heat waves) that points out that a migraine’s about to strike. Aura is often triggered from five to 20 minutes before a migraine strikes.

A detailed assessment of migraine aura symptoms is crucial for classification issues and pathophysiological discussion. Few studies have aimed on the detailed clinical aspects of migraine aura.

A study was conducted in which migraine aura attributed encompassing presence, quality, laterality, duration of each aura symptom, their temporal succession; presence of headache and its temporal succession with aura. A total 72 patients completed the study, recording the characteristics of three consecutive auras (n = 216 auras). The visual symptoms appeared in 212 (98%), sensory symptoms in 77 (36%) and dysphasic symptoms in 22 (10%). A majority of auras had more than one visual symptom (median 2, IQR 1–3, range 1–4). The majority of patients (56%) did not describe a stereotyped aura on the three attacks with respect to visual attributes, the combination and/or temporal succession of the three aura symptoms. A 57% patients also delineated a different scenario of temporal succession between aura and headache in the three attacks. Total 5% auras were longer than four hours.

Thus, we cease to know that these findings reveal a high inter- and intravariability of migraine with aura attacks. They also render reliable data to enrich and clarify the spectrum of the aura phenotype.
