Migraine aura symptom8/4/2023 Migraine with aura duration headache symptoms temporal features time. We provide data to suggest that symptoms may last longer than one hour in a relevant proportion of auras or migraine with aura patients, and that there is a high variability of scenarios in terms of time relationship among aura symptoms and between aura and headache. The headache phase started before the aura (9%), simultaneously with the onset of aura (14%), during the aura (26%), simultaneously with the end of aura (15%) or after the end of aura (36%). In aura with multiple symptoms the subsequent symptom, second versus first one or third versus second, might either start simultaneously (34 and 18%), during (37 and 55%), with the end (5 and 9%), or after (24 and 18%) the previous aura symptom. Twenty-six percent of patients had at least one aura out of three with one symptom lasting for more than one hour. Visual symptoms lasted for more than one hour in 14% of auras ( ITALIC! n = 158), sensory symptoms in 21% of auras ( ITALIC! n = 52), and dysphasic symptoms in 17% of auras ( ITALIC! n = 18). The median duration of visual, sensory and dysphasic symptoms were 30, 20 and 20 minutes, respectively. We conducted a prospective diary-aided study of the duration and the succession of aura symptoms and their temporal relationship with headache.įifty-four patients completed the study recording in a diary the characteristics of three consecutive auras ( ITALIC! n = 162 auras). Hitherto these temporal aspects have not been studied in detail. All rights reserved.As there are no biological markers, a detailed description of symptoms, particularly temporal characteristics, is crucial when diagnosing migraine aura. The prophylactic treatments for migraine with aura are those used in migraine without aura based on very few randomized clinical trials specifically dedicated to migraine with aura.Īura Cortical spreading depression Migraine.Ĭopyright © 2021 Elsevier Masson SAS. In case of failure of NSAIDs or aspirin it is recommended to use a triptan when the headache begins. It is recommended to start non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin as soon as possible during the aura phase, not to treat the aura, but to avoid or to diminish the headache phase. Combined hormonal contraception with estrogens significantly increases the risk of stroke in women with migraine with aura. The relative risk of ischemic stroke is significantly increased in migraine with aura. Some symptoms of migraine aura can look like a seizure, including vision problems, nausea, and uncontrolled movements. Long duration (greater than one hour) of what may or may not be an aura phase, late onset of aura, or a dramatic increase in aura attacks should also be explored. Epilepsy.You may get a bad headache before or after an epileptic seizure. If the patient has no visual aura symptoms or simultaneous neurological symptoms, or presents neurological symptoms corresponding to a cerebral vascular territory, emergency exploration of a possible transient ischemic attack is necessary. One or more of the following fully reversible aura symptoms: 1. When a patient experiences for the first time a possible aura phase it's sometimes difficult to know if there was gradual or brutal onset of the symptoms. At least two attacks fulfilling criteria B and C B. The accepted duration for most aura symptoms is one hour, but motor symptoms, which are rare, are often longer lasting. Some people experience tinnitus, dizziness or even the inability to speak clearly. Migraine aura refers to any number of sensory disturbances, including dots, sparks or zigzags in your vision. When aura symptoms are multiple, they usually follow one another in succession, beginning with visual, then sensory, then aphasic but the reverse and other orders have been noted. Overview What is a migraine aura Migraine aura is considered a warning stage that sometimes occurs before the onset of a migraine headache. Visual aura is the most common type of aura, occurring in over 90% of patients. Aura is characterized by gradual development, duration of each symptom no longer than one hour, a mix of positive and negative features, and complete reversibility. The diagnosis is based on the International Headache Classification Disorders III edition criteria. The pivotal role of cortical spreading depression (CSD) as a mechanism underlying aura has been widely supported by a large body of studies. Aura is a fully reversible focal neurological phenomenon involving visual, sensory, speech, and/or motor symptoms that develops gradually and usually precedes the headache phase. Examples are hallucinations, numbness, changes in speech, visual. Around 15% to one-third of migraineurs experience aura. The aura phase includes visual, sensory, or motor symptoms that occur just before the headache.
