Connection between dementia and migraines, and examined
Migraine is a widespread complaint image whose causes are not clarified until today, finally. However, it is known that migraine can in certain cases an increased risk of stroke and lead to changes in the brain tissue. In a recent study, it has now been investigated for the first time, whether also been linked with dementia risk. The result is quite reassuring.
In view of the vascular and neural changes in migraine in the professional world for some time now the suspicion that there was a connection with dementia could be at risk. A US research team led by Kristen M. George from the University of California, Davis Medical Center, has examined whether migraine can actually have an impact on the risk of Dementia. Their results were published in the journal “Headache”.
Connection with the loss of cognitive abilities?
“Whether migraine increases the risk of Dementia, has now been investigated for the first time in a large cohort of prospectively,” says the German society for neurology (DGN) from the current study. Due to the involvement of the brain will be discussed for a long time, whether there is a correlation between migraine and the loss of cognitive abilities or dementia vessels of the migraine symptoms.
Increased risk of stroke and changes in the brain
In particular, migraine headache disorders with Aura (i.e., with preceding visual disturbances such as Flickering or flashes of light, or neurological symptoms) are associated with a slightly increased risk of stroke, explains the DGN. Furthermore, it was shown in the ARIC study, an Association between migraine history and changes in the cerebral white matter, stroke-like lesions (“silent infarcts”), as well as brain volume changes.
More than 12,000 persons were examined
Such abnormalities in brain tissue associated according to the DGN, in turn, with an increased risk of cognitive disorders, which is why the question I put, whether migraine is a risk factor for the development of a dementia disease. On the basis of the data of 12.495 Participating (including 1.397 Migraine patients and in -patients) between the ages of 51 and 70 years, with a median follow-up time of 21 years, the U.S. research team possible looked to hang between the two Complaints.
No connection detected
A total of 18.5 percent of the individuals developed without migraine and 16.7 percent of persons with migraine, dementia, reported the research team of the results of the data analysis. “There was no connection between migraine and dementia and there was also no statistically significant interaction between gender and migraine Status with the risk of Dementia,” write the researchers.
Changes in the brain without clinical significance?
“Despite the fact that migraine patients have, in rare cases, changes in the brain tissue, the person Concerned has not at higher risk to develop a dementia”, almost the DGN press speaker Professor Dr. med. Hans-Christoph Diener of the results. At the present time, there is no evidence to suggest that in migraine occurring changes in the white matter have a clinical significance or a disease value.
However, the persons involved, especially women, suffer from migraine with Aura should be, according to Prof. servants in terms of their stroke risk is monitored and additional vascular Smoking risks, such as, for example, and hormone treatments to avoid. (fp)
