Diabetes linked to Alzheimer's development

High blood sugar could be linked to Alzheimer's disease, according to a study published in the Journal of Clinical Investigation.

The results of the study suggest diabetes can have harmful effects on brain function and may exacerbate neurological conditions such as Alzheimer's disease.

The research was carried out at Washington University School of Medicine, using mice, and it showed that high levels of the sugar glucose, a symptom of diabetes, can increase the levels of a toxic protein called amyloid that is associated with Alzheimer's disease.

Dr Clare Walton, Research Manager at Alzheimer's Society said: 'This study adds to a growing body of evidence that suggests there is a link between poorly managed diabetes and dementia.”

The Alzheimer's Society said they don't want people living with diabetes to worry that they will develop dementia, but they advise people who are concerned to contact their GP.

The charity is currently funding a clinical trial to test whether a common diabetes drug that lowers blood glucose can also be beneficial to people with early stage Alzheimer's disease.
