The Claim
In adults with amnestic mild cognitive impairment or mild dementia, a relative predominance of enlarged perivascular spaces in the centrum semiovale compared to the basal ganglia is associated with higher burdens of amyloid-beta and tau proteins.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults with memory problems due to early Alzheimer's or mild dementia, a higher concentration of enlarged fluid spaces around blood vessels in the brain's white matter compared to deeper brain regions is linked to greater accumulation of amyloid-beta and tau proteins.
See the scientific wording
In adults with amnestic mild cognitive impairment or mild dementia, the relative predominance of enlarged perivascular spaces in the centrum semiovale compared to the basal ganglia is associated with higher amyloid-beta and tau burden, suggesting regional EPVS distribution may help distinguish Alzheimer's-related pathology from vascular causes.
Fluid drainage channels around blood vessels in the white matter of the brain become enlarged and stop working properly, causing Alzheimer’s proteins to build up in that area instead of being cleared away, which damages brain cells and leads to memory problems.
What the research says
1 studyIn older adults with memory problems, having more fluid-filled spaces in the brain’s white matter (compared to deeper areas) is linked to higher levels of Alzheimer’s proteins, helping doctors tell it apart from brain changes caused by blood vessel problems.
