Migraines do not cause a decline in cognitive performance. Magnetic resonance imaging (MRI) has increased the number of so-called bright spots in the brain of migraine patients, but this has no effect on mental abilities, according to a study by US and Dutch researchers.
In the current study, scientists from the University of Leiden (Netherlands), Haga Hospital in The Hague (Netherlands), Slingeland Hospital in Doetinchem (Netherlands), Academic Hospital Maastricht (Netherlands) and the National Institute on Aging in Bethesda (Maryland) worked , USA) to analyze the possible effects of chronic migraines on the brain. The researchers published their results in the journal "Journal of the American Medical Association".
Almost 300 migraine patients examined The scientists evaluated the data of "295 well-characterized patients with migraines and 140 age- and gender-specific controls of the same age" as part of their study. The brains of the study participants were examined in 2000 and in 2009 using an MRI scan. At the first survey in 2000, the average age of the sample was 48 years and 71 percent were women. Earlier studies had shown that chronic migraines can lead to ischemic lesions (tissue damage due to insufficient blood flow) in the brain, but after nine years of testing, the Dutch and US researchers found no evidence of loss of the migraine patients determine mental faculties.
Bright spots in the brain of the migraine patients The examination in magnetic resonance tomographs showed so-called bright spots in the brain of the chronic migraine patients, but there was no increased progression of the other brain damage detectable on MRI, the researchers write. For those affected, this is definitely good news, especially since they are often already significantly restricted in their everyday lives due to the migraine symptoms. The massive headache, which can often go hand in hand with so-called aura symptoms such as dizziness, numbness in the extremities, visual disturbances, increased sensitivity to light and noise, often put the affected person completely out of action during the migraine attacks. An additional loss of mental performance would have been tantamount to bad news. However, the current study gives the all-clear at this point. Mark Kruti from the Institute of Radiology at the Leiden University Medical Center emphasized that her study showed no loss of memory, concentration and attention from chronic migraines and that preventive "aggressive treatment methods" can therefore be dispensed with.
