Once again, diabetes and Alzheimer’s are sharing headlines. A study conducted by researchers from Lancaster University in the U.K. has shown that a commonly used diabetes drug, liraglutide, may reverse memory loss in the late stages of Alzheimer's.
The drug, from a class known as GLP-1 (Glucagon-like peptide-1) analogue, is prescribed to diabetes patients because it stimulates insulin production. The new study found that liraglutide passes through the blood-brain barrier where it could prevent the build-up of toxic plaques in the brain that contribute to Alzheimer’s disease. Liraglutide may also improve memory function that was previously lost.
In the study, liraglutide was injected into mice that had late stage Alzheimer’s disease. During the two-month trial period, the mice performed significantly better on object recognition tests than before, and their brains showed a 30 percent reduction in the build-up of toxic plaques.

What's better than a sale at Walmart? I'll tell you-a well done research project on learning and memory which has promising results for diabetics! Having vascular dementia, I am forever struggling with my short term memory. I am also diabetic , which doesn't help. So, when I found this research report, I was elated. There is hope for diabetics and dementia. It may not occur in my lifetime, but at least the National Institute on Aging is on the right path. Nature Neuroscience , Feb. 17, 2008, reported on a study performed by the National Institute on Aging. The researchers tested the cognitive abilities and examined the brain tissue in animal models of rats with Type 1 diabetes and mice with Type 2 diabetes. They discovered that elevated cortisol levels caused learning and memory deficits in both models. When the cortisol levels (low due to impaired elasticity and declining new cell growth) were restored to normal levels, learning and memory was restored. Mention wa...
A mild decline in memory and the rate of information processing occurs normally with age, but does not affect daily function and does not generally progress. Like the body's muscles, bones, and other vital organs, the brain feels the effect of aging. Through years of constant use and biological wear and tear, the brain gradually loses some of its sharpness in processing information and in relaying the multitude of signals essential to day-to-day functioning. As people begin to age, they may begin to have problems with memory. One of the most noticeable problem areas involves the transient forgetting of names. Virtually everyone has this problem in older age. It is important to note that normal age-related memory loss does not indicate diminished intelligence or ability to learn. The brain may simply need more time to recall information from memory or to learn new information. Simple forgetfulness is not a disease. Studies on learning and memory constitute an active area of research f...
