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.
