Uncontrolled diabetes raises dementia risk
Uncontrolled diabetes increases the risk of Alzheimer's disease and other types of dementia, according to research by a Swedish team.
Researchers analysed blood glucose data in a cohort of 1,250 Swedish patients who were aged 75 at the start of the study, giving them cognitive tests and clinical examinations every three years for a median of nine years.
Uncontrolled diabetes was associated with a 10-fold increased risk of vascular dementia and a three-fold increased risk of Alzheimer's disease compared with patients with normal glucose levels.
