Migraining Women Likely To Develop Dementia: Study

Dementia Risk For Migraineurs

 

Migraineurs With Aura Are 48% More Likely To Develop Dementia In Later Life (1)

As if the sustained pounding, debilitating pain, the flurry of traumatic symptoms and ineffective medicines were not enough for migraineurs, studies are now showing that persons who suffer migraines with visual and other aura are 48% more likely to develop dementia as they begin to age than their healthier counterparts! (2)

In part this could be explained by the presence of white matter lesions that the brains of migraineurs are often seemed to have when scanned using an MRI (Magnetic Resonance Imaging).

We know that white matter of the brain consists of nerve fibres (axons) and are surrounded by fat called myelin (3). The main function of the white matter is to transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centres. Lesions in the white matter interfere with signal transmissions. Damage to this white matter is a common significant factor observed in all those suffering from dementia.

Earlier control tests and those conducted at the Changhua Christian Hospital, Taiwan has already shown that migraineurs are at an exponential risk of diabetes and of developing hypertension, depression and cardiovascular diseases.

However, other studies have shown that the mental status of women with a history of migraine was no different from other women’s, so more research is needed.

Migraine With Aura Pegs Risk For All Stroke Types In Women

mIGRAINE sTROKE

Women Migraineurs Experiencing Aura Are At An Increased Risk Of Suffering All Stroke Types (1)

A research that studied 28,000 women has found that such women as those who experience migraines with aura – either visual or sensational and non-visual are at a significantly increased risk of suffering from all types of strokes (ischemic or hemorrhagic ) as those compared to women who do not experience migraines. The findings of the study are to be presented at the International Headache Congress 2013 at Boston. (2)

Ischemic strokes occur when there is a blockage causing reduced blood supply to any part of the brain leading to brain cell and tissue death. Hemorrhagic stroke occurs when an artery in the brain ruptures and causes bleeding in the brain.

Visual aura in migraineurs is a neurological phenomenon typified by visual aberrations or distortions such as perceiving an image as partly broken or with zigzag lines, experiencing blind spots, having a vision festered with sparks or flashing and shimmering lights, inability to gauge distance or margin between two objects. It could involve seeing of wavy lines and experiencing hallucinations. (3)

Aura a migraineur may suffer from may be non-visual in nature such as experiencing vertigo, numbness of tongue, feeling pins and needles on the palms and face or even experiencing of motor debility.

According to Dr. Tobias Kurth, of Brigham and Women’s Hospital in Boston , “Migraine with aura has been consistently linked with increased risk of ischemic stroke and there is also some evidence that it increases risk of hemorrhagic stroke. In this study we sought to determine the importance of migraine with aura in stroke occurrence relative to other stroke risk factors” (4)

The following observations were made during the study:

Period

Migraineurs With Aura

Cardiovascular Patients

Base Year or Year 0 1435 0
Year 15 1435 528 strokes:

  • 430 Ischemic
  • 96 Hemorrhagic
  • 02 Unknown strokes

It was concluded in the news release that for total, ischemic and hemorrhagic stroke, migraine with aura was a strong relative contributor.

Caution: The data and conclusions of research presented at medical meetings are typically considered preliminary until published in a peer-reviewed medical journal.
