Investigating how obesity affects brain blood and lymphatic vessels and cognitive function in older adults

Official title: Dysfunction of brain microvascular and lymphatic vessels in obesity-linked cognitive impairment

Funded at Johns Hopkins University · NIH-11128893 · Data updated 2026-11-12

This study is looking at how being overweight might affect thinking and memory in older adults, especially those with Alzheimer's or dementia, and it hopes to find easy ways to spot early signs of these issues so that better treatments can be developed.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals aged 65 and older who are experiencing cognitive decline or have a history of obesity.

Less likely to help

Patients who are younger than 65 or do not have obesity-related cognitive impairment may not benefit from this research.

What this research studies

This research focuses on understanding the relationship between obesity and cognitive impairment in older adults, particularly in the context of Alzheimer's disease and dementia. It aims to identify non-invasive biomarkers for early diagnosis and treatment evaluation of cognitive decline linked to obesity. Using advanced magnetic resonance imaging (MRI) techniques, the study will assess changes in brain blood and lymphatic vessels, neuroinflammation, and the integrity of the blood-brain barrier. The findings could lead to better interventions for those affected by obesity-related cognitive issues.

Why it matters

Potential benefit: If successful, this research could lead to improved diagnostic tools and treatments for cognitive impairment associated with obesity in older adults.

How similar studies have gone: Previous research has shown promising results in using MRI techniques to study neurovascular changes in relation to cognitive impairment, suggesting that this approach could yield valuable insights.
