Slow walking predicts dementia risk

An 11-year follow-up of 2,410 people showed that slower walking speed was associated with a 50 percent higher risk of dementia.

Slow walkers also tend to have significantly lower brain volume and performance on cognitive function tests compared to peers who walked faster, says the report that will be presented at the American Academy of Neurology meeting in April.

The findings also disclosed that although grip strength was not generally associated with stroke risk, those who aged 65 and older had a 42 percent higher risk of stroke if they had higher baseline grip strength.

“These are basic office tests [that] can provide insight into the risk of dementia and stroke and can be easily performed by a neurologist or general practitioner,” said lead researcher Dr. Erica C. Camargo of Boston Medical Center.

“While frailty and lower physical performance in elderly people have been associated with an increased risk of dementia, we weren’t sure until now how it impacted people of middle age,” she added.

The two basic tests can be easily performed by doctors in their office and provide them a better insight into patients’ risk of dementia and stroke, researchers concluded.

They suggested that further investigations may provide a better understanding of how early risks of dementia and stroke may affect younger people’s walking speed and hand grip strength.
