Weight loss improves memory in type II diabetes

25 May

A thesis from Umeå University titled “Brain function and glucocorticoids in obesity and type 2 diabetes including effects of lifestyle interventions.”  From the conclusion:

” Cortisol levels are linked to prefrontal brain structure and, at least in type 2 diabetes, lower memory performance. Furthermore, the dysregulated GC metabolism in obesity can be reversed by long-term diet- induced weight loss. Finally, dietary interventions with associated metabolic improvements alter functional brain responses during memory testing, including increased activation of the hippocampus. Whether these changes are linked to alterations in GC exposure and mediate improved cognition requires further study. “

Fish consumption may increase diabetes risk

6 May

I have blogged a number of times about the relationship between diabetes and dementia. Now there is evidence that fish consumption may increase your risk of type 2 diabetes.

Is Alzheimer’s disease type III diabetes?

19 Dec

I have come across a number of blog posts recently suggesting that Alzheimer’s disease might be a kind of diabetes. This is an interesting conjecture because it might help explain the connection between life-style and dementia.

Here is a review article published in 2008 that examines the evidence. The authors state:

“We conclude that the term “type 3 diabetes” accurately reflects the fact that AD represents a form of diabetes that selectively involves the brain and has molecular and biochemical features that overlap with both type 1 diabetes mellitus and T2DM.”

Risk of dementia is definitely higher for people with diabetes. Thus, it would be prudent to take steps that reduce our risk of diabetes.

High blood sugar level linked to dementia

10 Aug

For several decades, there has been speculation that blood sugar dysregulation might play a role in Alzheimer’s disease and other forms of dementia. This is because people with type II, adult on set, diabetes, have been shown to have a higher risk of dementia.

Now a study published in The New England Journal of Medicine, has provided additional support for this hypothesis. The most surprising finding was that a higher blood sugar level was associated with a higher risk of dementia even for people who did not have diabetes.  The New York Times has a good summary.

While these findings are still tentative, the prudent course of action is to take steps to reduce your risk of high blood sugar and diabetes. This includes exercise and a plant based diet.
