Men who develop diabetes in middle age may have significantly higher odds of developing Alzheimer’s disease, research suggests.
A study of more than 2,000 men found that low insulin secretion capacity at age 50 was linked to a one and times increased risk of developing Alzheimer’s disease.
This risk remained significant regardless of changes in blood pressure, cholesterol and body mass index.
Study author Elina Ronnemaa said: “Our results have important public health implications given the increasing numbers of people developing diabetes and the need for more powerful interventions.”
She suggests that low insulin secretion may damage blood vessels in the brain, leading to memory problems and Alzheimer’s disease.
The Alzheimer’s Society suggests that eating a balanced diet and exercising regularly in middle age are the best ways of reducing risk of dementia, heart disease and diabetes.
They believe that further research is now needed to determine how diabetes increases risk of Alzheimer’s disease and other forms of dementia. Alzheimer's Society
