Stress raises the risk of cognitive decline in older adults with diabetes.

New research from the University of Edinburgh has shown that stress raises the risk of memory loss and cognitive decline among older people with diabetes. 

The researchers studied more than 900 men and women aged between 60 and 75 with type-2 diabetes and evaluated their mental abilities with a range of tests, including memory function and speed of information processing. This was compared with general intelligence levels to gauge brain function over time.

Their findings showed that brain function slowed in participants who had higher levels of the stress hormone cortisol.

Dr Rebecca Reynolds, of Edinburgh University’s  Centre for Cardiovascular Science, said: “We know that type 2 diabetes is linked to problems with memory, but the reason behind this is unclear.”

This work is part of the Edinburgh Type 2 Diabetes Study. You can read more about these results here.

Aerobic exercise benefits for older adults.

Dr. Kenneth Madden, speaking at the 2009 Canadian Cardiovascular Congress, has unveiled new research that demonstrates the benefits of aerobic exercise for older adults. Dr. Madden’s work studied a group of adults  between the ages of 65-83 with controlled Type 2 diabetes, high blood pressure, and high blood cholesterol. Three months of exercise resulted in an improvement  in the elasticity of the arteries of the group that performed the activity compared to those who didn’t exercise.img_logo_ccs_bil

“The subjects were divided into two groups to either receive three months of vigorous physical activity (one hour, three times per week) or to get no aerobic exercise at all. Subjects were classified as sedentary at the beginning of the study but gradually increased their fitness levels until they were working at 70 per cent of their maximum heart rate, using treadmills and cycling machines. They were supervised by a certified exercise trainer.”

While some may worry about the high level of activity engaged in by the participants, Dr Madden says “There seems to be a knee-jerk reluctance to getting these older adults to exercise yet we used a vigorous level of activity and didn’t have any trouble keeping participants in our study. They enjoyed the activity. People always underestimate what older adults can do.”

He also notes, however, that many people need a kick start to motivate them into a regular fitness program.  In aid of this, you can visit the Nova Scotia Department of Health Promotion and Protection’s Senior section here, and find your local YMCA here.
