Scientists from Vail Cornella Medical College found that intracranial hemorrhages caused by the breaks of brain vessels could increase the risk of dementia in old age. The results of the work published Magazine stroke.
During the study, scientists analyzed the medical history of approximately 15,000 people who had various types of intracranial bleeding from 2008 to 2018. Scientists focused on cases of spontaneously, not as a result of head injuries. The results showed that the risk of dementia was doubled after an average of 5.6 years after the bleeding in the brain.
These data are consistent with the data of other studies showing that intracranial hemorrhages are associated with the risk of cognitive disorder. For example, the work of Danish scientists showed that 11.5% of people who have spent brain vessels in a gap developed dementia. This indicator is 2.5 times higher than the general population.
The causes of the connection between intracranial bleeding and dementia may be different.
“One of the possible reasons is the accumulation of a beta-amiloid protein in the brain after a violation of ships. There is also a hypothesis that general factors, such as chronic damage to the vessels of the brain, can increase both bleeding and the risk of dementia, ”he added.
