A common type of brain hemorrhage in the elderly, known as subdural hemorrhage, is caused by the buildup of amyloid protein in the blood vessels surrounding the organ. This conclusion was reached by researchers from New York-Presbyterian Hospital and Yale School of Medicine. results published In JAMA Neurology.
More than 600 thousand British and Americans participated in the research. Scientists collected information about the health status of the subjects and identified people with cerebral amyloid angiopathy (CAA). This is a disease of the small vessels of the brain, which manifests itself in old age. It is characterized by the progressive deposition of amyloid protein in small and medium-sized arteries and capillaries.
Researchers found that participants with this condition were five times more likely to experience subdural bleeding compared to people without CAA. Subdural bleeding occurs due to rupture of blood vessels in the dura mater. It is represented by a dense connective tissue with a fibrous structure.
The authors explained that this apparent statistical correlation does not mean that CAA causes subdural hemorrhages. More research is needed to determine the mechanisms underlying this relationship.
