The Claim

Cumulative impaired fasting glucose is associated with a higher risk of dementia, and this association is stronger in non-obese individuals compared to obese individuals.

In plain English

People with consistently elevated fasting blood glucose levels have a higher risk of developing dementia, and this risk is greater in those who are not obese than in those who are obese.

See the scientific wording

The association between cumulative impaired fasting glucose and increased dementia risk is significantly stronger in non-obese individuals than in obese individuals, suggesting that mild hyperglycemia may be a more relevant risk factor for neurodegeneration in metabolically healthier populations.

Why this might work

When blood sugar stays slightly high over time, the brain becomes less able to use insulin properly, which causes brain cells to get less energy and triggers inflammation that damages neurons, leading to memory loss and dementia.

  1. Study: Cumulative effect of impaired fasting glucose on the risk of dementia in middle-aged and elderly people: a nationwide cohort study

    In people who aren’t overweight, having slightly high blood sugar over time is more strongly linked to dementia than in people who are overweight. This suggests that even small glucose problems matter more when the body isn’t already struggling with obesity.
