Does Diabetes Slow Alzheimer's?
MONDAY, Oct. 26 (HealthDay News) -- A French study finding that people with Alzheimer's disease and diabetes have less memory loss than those without diabetes should be regarded with caution, American experts say.
"It's not clear from this study and others what the relationship is," said William Thies, chief medical and scientific officer of the Alzheimer's Association.
What is clear, Thies said, is that having diabetes increases the risk of developing Alzheimer's disease -- a relationship acknowledged in the first sentence of a report on the French study in the Oct. 27 issue of Neurology.
But there haven't been too many studies looking at the effect of diabetes on the progression of Alzheimer's, said the report by researchers at INSERM, the French National Institute for Health and Medical Research in Toulouse.
So, they followed 608 people with mild to moderate Alzheimer's disease for four years, testing their memory and thinking skills twice a year.
The 63 participants with diabetes -- 10.4 percent of the total -- started with the same average score of 20 on the test of thinking ability. There was an average overall decline of 1.24 points on that test every six months.
