A new study presented at the American Academy of Neurology annual meet has linked dementia with the strength of hand grip and walking speed and said that those who walked slowly were 1.5 times more likely to suffer from the mental condition.
The study was conducted by researchers from the Boston Medical Centre in United States who observed more than 2,400 men and women with an average age of 62 years. All of the participants underwent tests for hand grip strength and walking speed along with a number of mental tests.
AdvertisementAfter a follow-up period of 11 years, the researchers found that 34 people had suffered from dementia while around 70 had suffered from a stroke. The researchers found that those who scored lower in hand grip strength test and walking speeds were more likely to develop dementia.
"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", lead researcher Dr Erica Camargo said before adding that more research is needed to know exactly why the risk of dementia increases with slow walking speeds.
