Migraine with aura linked to risk of stroke only after age 50 years

Migraine with aura linked to risk of stroke only after age 50 years

In a new study it has been revealed that Migraine with aura linked to risk of stroke only after age 50 years whereas at an earlier age, onset of migraine with aura was not associated with a higher risk of ischemic stroke. This study underscores the importance of the age of onset of Migraine with Aura in assessing stroke risk in older migraineurs. The study has been published in Headache.

In an earlier study published in Atherosclerosis Risk in Communities it was revealed that Migraine with aura was associated with an increased risk of ischemic stroke without any reference of age of onset of disease.

The analysis included 447 migraineurs with aura (MA) and 1,128 migraineurs without aura (MO) among 11,592 participants (elderly men and women with a history of migraine). Over 20 years, there was a twofold increased risk of ischemic stroke when the age of MA onset was 50 years or older when compared with no headache. MA onset before 50 years old was not associated with stroke. Also, MO was not associated with increased stroke risk regardless of age of onset.

In the elderly population in this study, the absolute risk for stroke in MA was 37/447 (8.27 percent) and in MO was 48/1,128 (4.25 percent).Longer cumulative exposure to migraine with visual aura, as would be expected with early onset of migraine, was not associated with increased risk of ischemic stroke in late life.

“I think clinically this is very meaningful, as many individuals with a long history of migraine are concerned about their stroke risk, especially when they get older and when they have other cardiovascular disease risks,” said lead author Dr. X. Michelle Androulakis, Chief of Neurology at WJB Dorn VA Medical Center, in South Carolina. “Cumulative effects of migraine alone–with onset of migraine before age of 50–did not increase stroke risk in late life in this study cohort. On the contrary, the recent onset of migraine at or after age 50 is associated with increased stroke risk in late life.”
