New study finds link with high blood sugar and Alzheimer’s disease


Monday 4th May a study was published in the Journal of Clinical Investigation that highlights scientists uncovering a mechanism that links high blood sugar with Alzheimer’s disease.

The research by Washington University School of Medicine was carried out in mice; with results suggesting diabetes to have harmful effects on brain function and may exaggerate neurological disorders such as Alzheimer’s disease.

This is due to having high levels of sugar glucose increasing the levels of a toxic protein called amyloid associated with Alzheimer’s.

Dr Clare Walton, Research Manager at Alzheimer’s Society said;

‘This study in mice adds to a growing body of evidence that suggests there is a link between poorly managed diabetes and dementia.

This latest research provides a potential insight into why this link exists and indicates that keeping levels of blood glucose within the normal range may help to reduce the production of the toxic amyloid protein, a known contributor to Alzheimer’s disease.

Alzheimer’s Society 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.

Whilst we don’t want people living with diabetes to worry that they will develop dementia, we would advise people who are concerned to contact their GP.

The best way to reduce the risk of developing dementia is to eat a healthy balanced diet, take plenty of exercise and not smoke.’
