The Claim

The risk of Alzheimer’s disease increases in a dose-dependent manner with the duration of impaired fasting glucose exposure, with four consecutive years of exposure associated with approximately a 14% higher risk compared to no exposure, indicating a cumulative biological effect of mild hyperglycemia.

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.

Cause and effect
1 study reviewed
In plain English

People with impaired fasting glucose for four consecutive years have a 14% higher risk of developing Alzheimer’s disease than those with no exposure, and longer exposure is linked to greater risk.

See the scientific wording

The risk of Alzheimer’s disease increases in a dose-dependent manner with the number of years of impaired fasting glucose exposure, with individuals exposed for four consecutive years showing approximately 14% higher risk than those with no exposure, indicating a cumulative biological effect of mild hyperglycemia.

Why this might work

Long-term slightly high blood sugar stops the brain from using insulin properly, which causes toxic proteins to build up in brain cells and damages blood vessels, leading to memory loss over time.

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

    People who had slightly high blood sugar for four years in a row were about 14% more likely to get Alzheimer’s than those who never had it, showing that even small, long-term sugar spikes can hurt the brain over time.
