Alzheimer's Society responds to research linking insulin resistance and cognitive decline

A study by the University of Tel Aviv has found that resistance to insulin may be linked to an increase in cognitive decline.

Published in the Journal of Alzheimer's Disease, the research finds that insulin resistance, caused in part by obesity and physical inactivity, is also linked to a more rapid decline in cognitive performance. The researchers say that both the diabetic and non-diabetic participants in the 20 year trial, all of whom have insulin resistance, experienced accelerated cognitive decline in executive function and memory.

Responding to this, Dr James Pickett, Head of Research, at Alzheimer’s Society, said:

'There is strong evidence that poorly-managed diabetes can increase your risk of dementia. This research highlights that insulin resistance – which is related to diabetes – could have a negative impact on a person’s memory or thinking abilities.

'The study also adds to existing evidence that keeping our hearts and brains healthy as we age by eating well, exercising and not smoking are the best things we can do to reduce our risk of memory problems in later life.'
