How obesity and type 2 diabetes that start in youth affect the brain's blood vessels and thinking

Understanding the Impact of Youth Onset Obesity and Type 2 Diabetes on the Neurovascular Unit

NIH-funded research Cincinnati Childrens Hosp Med Ctr · NIH-11264837

Doctors will compare brain scans, blood flow, and thinking skills in teens with early-onset type 2 diabetes, teens with obesity but no diabetes, and lean peers to learn how diabetes affects the brain.

What this research studies

You would join one of three groups: adolescents with type 2 diabetes that began in youth, age-matched adolescents with obesity but no diabetes, or lean peers. You would receive MRI scans to measure brain structure and cerebral blood flow, blood tests, and tests of memory and other thinking skills. The team will look at gray matter volume, blood flow, and markers related to the brain's blood–brain barrier and vascular health to distinguish effects of diabetes from obesity. Results will be compared across groups to see whether early diabetes is linked to changes in brain blood vessels and cognitive function.

Who could benefit from this research

Good fit: Ideal participants are adolescents and young adults diagnosed with type 2 diabetes during their youth, plus age-matched obese and lean peers for comparison.

Not a fit: Older adults with typical adult-onset type 2 diabetes, people without a history of obesity or diabetes, and children younger than the adolescent range are unlikely to match the study groups or benefit directly.

Why it matters

Potential benefit: If successful, this work could reveal early brain changes tied to youth-onset type 2 diabetes and lead to earlier monitoring or treatments to protect thinking and brain health.

How similar studies have performed: Prior smaller studies, including the investigators' own work, have shown reduced gray matter volume and lower cerebral blood flow in youth-onset type 2 diabetes, but larger focused comparisons separating diabetes from obesity are relatively new.
