People with Cerebral Amyloid Angiopathy More Likely to Develop Dementia

People with cerebral amyloid angiopathy more likely to develop dementia

Cerebral amyloid angiopathy (CAA) is a condition where protein (called amyloid) builds up in the brain, making blood vessels weak.

Protein buildup in brain blood vessels linked with increased 5-year risk of dementia

Cerebral amyloid angiopathy (CAA) is a condition where protein (called amyloid) builds up in the brain, making blood vessels weak. People with CAA are four times more likely to develop dementia within five years, regardless of whether they have had a stroke, according to a preliminary study presented at the American Stroke Association's International Stroke Conference 2026, held in New Orleans, Feb. 4–6, 2026.

This Brain Condition Quadruples Dementia Risk And Most People Have Never Heard of It

Research Highlights A large U.S. study of nearly 2 million older adults found that cerebral amyloid angiopathy, a condition in which amyloid proteins build up in brain blood vessels, is linked to a much higher risk of developing dementia within five years. The increased dementia risk appeared consistently in people with cerebral amyloid angiopathy whether [...]

Study Links Cerebral Amyloid Angiopathy to Fourfold Increase in Dementia Risk Within Five Years

A preliminary study analyzing health data from nearly 2 million U.S. adults covered by Medicare has found that cerebral amyloid angiopathy (CAA) significantly increases the risk of developing dementia within five years. The research, to be presented at the American Stroke Association’s International Stroke Conference 2026, indicates that individuals with CAA are approximately four times more likely to receive a dementia diagnosis compared to tho…
