ISLAMABAD: A diabetes drug may be used to treat Alzheimer’s disease after significantly reversing memory loss in mice, said scientists.

The research could bring substantial improvements in the treatment of Alzheimer’s disease through the use of a drug originally created to treat type 2 diabetes,  Health news reported.

Lead researcher Professor Christian Holscher of Lancaster University in the UK said the novel treatment “holds clear promise of being developed into a new treatment for chronic neurodegenerative disorders such as Alzheimer’s disease.”

Dr Doug Brown, Director of Research and Development at Alzheimer’s Society, said: “With no new treatments in nearly 15 years, we need to find new ways of tackling Alzheimer’s. It’s imperative that we explore whether drugs developed to treat other conditions can benefit people with Alzheimer’s and other forms of dementia. This approach to research could make it much quicker to get promising new drugs to the people who need them.”

This is the first time that a triple receptor drug has been used which acts in multiple ways to protect the brain from degeneration. It combines GLP-1, GIP and Glucagon which are all growth factors. Problems with growth factor signalling have been shown to be impaired in the brains of Alzheimer’s patients.

The study used APP/PS1 mice, which are transgenic mice that express human mutated genes that cause Alzheimer’s. Those genes have been found in people who have a form of Alzheimer’s that can be inherited. Aged transgenic mice in the advanced stages of neurodegeneration were treated.

In a maze test, learning and memory formation were much improved by the drug which also:-enhanced levels of a brain growth factor which protects nerve cell functioninga and reduced the amount of amyloid plaques in the brain linked with Alzheimer’s, Reduced both chronic inflammation and oxidative stress,slowed down the rate of nerve cell loss.

Professor Holscher said: “These very promising outcomes demonstrate the efficacy of these novel multiple receptor drugs that originally were developed to treat type 2 diabetes but have shown consistent neuro- protective effects in several studies.”

“Clinical studies with an older version of this drug type already showed very promising results in people with Alzheimer’s disease or with mood disorders” –APP
