A newly published study reveals a significant link between vascular health and dementia risk, finding that protein buildup in brain blood vessels may quadruple the likelihood of developing the condition in older adults. Affecting an estimated 30% of those over 80, cerebral amyloid angiopathy (CAA) – the underlying cause of this protein accumulation – is increasingly recognized as a critical, and often overlooked, component of neurodegenerative disease [[1]]. This research underscores the growing understanding that dementia isn’t solely linked to neuronal damage, but also to the health of the brain’s circulatory system [[2]], [[3]].
A buildup of proteins in the walls of blood vessels in the brain may increase the risk of dementia by as much as four times in older adults, a new study has found. This research highlights the importance of understanding vascular health as a key factor in cognitive decline.
Scientists explain that cerebral amyloid angiopathy (CAA) is a common disorder affecting blood vessels in aging individuals. It involves the accumulation of protein “waste” in the walls of capillaries and medium-sized arteries. This buildup weakens the vessels and raises the risk of stroke and brain hemorrhage, researchers said.
