Insulin Spray Could Potentially Prevent Alzheimer's

Last updated on Tuesday, September 20, 2011

(INDIANAPOLIS) - A study published in neurology suggests a new insulin spray could potentially prevent Alzheimer’s.

The study further adds to evidence that people with type 2 diabetes are at an increased risk for Alzheimer's.

Researchers looked at over 1,000 people aged 60 or older, with some diagnosed with diabetes. The participants were monitored for 11 years and then tested for dementia, which found 27-percent with diabetes developed dementia, compared to 20-percent of those without diabetes who developed dementia.

I.U. Medical School Associate Professor of Neurology, Ann Hake, says she's not surprised about the link of an insulin spray possibly preventing Alzheimer's.

Hake says people with diabetes, or just insulin resistance, in middle age have about twice the risk of having Alzheimer's later in life. Hake says some even call Alzheimer's "type 3 diabetes".

She says one major factor about the link is some of the areas of the brain with the highest amount of insulin receptors also happen to be some of the memory receptors in the brain.

She says walking for 30 minutes lowers insulin resistance for 24 hours, so increased activity helps increase odds of not getting Alzheimer's later in life.
