An aura usually lasts 20 to 30 minutes but can remain for as long as an hour.

Aura usually takes place 5 to 60 minutes before the migraine sets in and may include flashing lights or visuals resembling TV static or zigzag lines. Most migraine sufferers appear to be sensitive to various triggers, such as the menstrual cycle, weather changes, skipped meals, disturbed sleep, bright lights, odors, stress, or certain foods and beverages.Īn estimated 25 percent to 30 percent of migraine victims experience what's called "aura" prior to an attack. Specific, abnormal genes have been identified for some migraine forms. People with migraine are predisposed to attacks triggered by a range of factors. They now believe migraine results from inherited abnormalities in certain brain cells. Its symptoms result from changes in the brain, not inadequate coping mechanisms.įor many years, scientists believed migraines were linked to the dilation and constriction of blood vessels in the head. Gender aside, nearly half of migraine sufferers could benefit from preventive therapies, according to the American Migraine Prevalence and Prevention (AMPP) Study.Īlthough some people equate them with a person's stress level, a migraine is a biological disorder.

Researchers have found that migraines affect women more profoundly than they do men, interfering with professional development and family and social life. Women experience migraines three times more frequently than men. In the United States, about 12 percent to 16 percent of the population suffers from migraine headaches. They can eventually lead to lower self-confidence and a feeling of losing control. As anyone who's suffered a migraine can tell you, these headaches can disrupt every aspect of a person's life, from the ability to work to day-to-day activities to relationships. Migraines differ from other types of headaches in that they are brutally painful and are often accompanied by nausea or sensitivity to light and sound. But unfortunately, up to one in five women deal with migraine headaches on a regular basis. Let alone while juggling the crippling pain of a migraine.
Its symptoms are the result of changes in the brain, not a weakness in character or an inappropriate reaction to stress.Īs busy women, we can barely fit in everything we have to do as it is. Patients with episodes similar in characteristics to the ones described in this survey appear to have a benign neurologic prognosis, and do not require further neurodiagnostic studies.Migraine is a biologically based disorder. No neurologic disorder was identified after neurodiagnostic testing, clinical evaluation, and natural history observation.Ĭonclusions: The syndrome of idiopathic episodic unilateral mydriasis probably comprises a heterogeneous group of conditions that result in parasympathetic insufficiency of the iris sphincter in some patients, and sympathetic hyperactivity of the iris dilator in others. Five other patients examined during an attack had normal vision and unimpaired direct light reactivity of their large pupil. None of these patients had a tonic pupil or cholinergic agonist-induced pharmacologic mydriasis. Three patients who were examined had impaired near vision, four had impaired accommodative function, and six had an anisocoria that increased with added ambient light. Eleven patients were examined during an attack. The most common associated symptoms during an episode included visual blur in 15 patients, headache in 9, and orbital pain in 5. Most patients did not identify any factor that could precipitate an occurrence. The median duration and frequency of events were 12 hours and two to three per month, respectively. The median interval between onset of events and evaluation was 6 months.
Methods: Information was obtained by reviewing the case records of 24 patients evaluated by the author and collected by polling other neuro-ophthalmologists. Purpose: To describe the clinical features of the syndrome of neurologically isolated episodic unilateral mydriasis.
