Reviewing the possible connection between cerebral amyloid angiopathy and blood–brain barrier integrity in Down syndrome

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract Individuals with Down syndrome (DS) have a higher risk of developing cerebral amyloid angiopathy (CAA), primarily because of the excessive production of amyloid beta (Aβ). However, the consequences of CAA on blood–brain barrier (BBB) integrity and the neurovascular unit (NVU) are still not well understood.
