Brain 'Drain' Clog May Signal Early Dementia
23 Nov
Summary
- Enlarged perivascular spaces indicate potential dementia.
- MRI scans can now detect these 'clogged drains'.
- Early detection may improve treatment for Alzheimer's.

Scientists have identified enlarged perivascular spaces (EPVS), described as 'clogged drains' in the brain, as a potential early warning sign for dementia. This condition, where fluid-filled cavities around small blood vessels enlarge, is visible on standard MRI scans. Research indicates that individuals with mild cognitive impairment tend to show more EPVS, suggesting a link to Alzheimer's disease, the most common form of dementia.
The findings, stemming from a study involving nearly 1,000 participants at Nanyang Technological University, offer a promising avenue for earlier diagnosis. Detecting EPVS could complement existing methods for identifying Alzheimer's, allowing for timely interventions. This could potentially slow the progression of the disease and improve patient outcomes before irreversible brain damage takes hold.
While white matter damage is currently a common indicator for dementia assessment on MRI, these new findings highlight the unique value of EPVS. Early detection through these scans could enhance clinical treatment strategies and eventually become a key tool in predicting Alzheimer's development, offering new hope for millions affected by the condition worldwide.
