Regular exercise could provide beneficial affects for dementia patients

Research published in the journal Neurology has advised that taking regular exercise may provide a small benefit for people with early signs of dementia.

A clinical trial on two groups of elderly people with early signs of vascular dementia indicated that this who followed an exercise programme saw a small improvement in overall thinking skills, compared to those who did not exercise.

The condition causes memory loss and difficulties with thinking, problem-solving and language - and occurs when there are problems with the supply of blood to the brain.

However, half the group which took part in a one-hour exercise class three times a week for a six-month period, showed 1.7 improvement rate on their overall thinking skills. While the other group, which followed a healthy diet but did not exercise showed no improvement.

Study author Teresa Liu-Ambrose, from the University of British Columbia in Vancouver, Canada, said: "This result, while modest, was similar to that seen in previous studies testing the use of drugs for people with vascular cognitive impairment.

"However, the difference was less than what is considered to be the minimal clinically important difference of three points."

Commenting on the findings, Rosa Sancho, head of research at Alzheimer's Research UK, said: "We know that regular aerobic exercise can help improve cardiovascular health, but it has also been linked with a healthy brain and a reduced risk of developing dementia.

"This new study suggests that an aerobic exercise programme may be beneficial for people who already have early memory problems.

"While many studies have found a link between physical activity and dementia risk, few have tested specific intervention programmes and it's positive to see new trials in this important area.

"This small trial suggested that benefits may only be apparent while someone is actively engaged in an exercise programme, which will need following up in longer studies.

"With limited treatment options for people with memory decline or dementia, it's important to explore a range of possible therapeutic approaches."

She added: "Physical activity does not necessarily mean running marathons, but can involve a brisk regular walk with friends as part of a normal daily routine for people of any age."
