Middle-aged people who walk slowly and have a poor grip could be at greater risk of dementia or stroke in later life, researchers have warned. <\/p>\n
Simple tests of physical ability may give clues as to who is most likely to go on to develop disorders such as Alzheimer\u2019s and, to a lesser extent, suffer a stroke, they say. <\/p>\n
Their study involved monitoring more than 2,400 participants with an average age of 62 over 11 years. <\/p>\n
Tight grip: Research has found that simple tests on things like how fast a person walks may help doctors determine how likely that person might suffer dementia or a stroke <\/p>\n
Those with a slower walking speed were found to be one and a half times more likely to develop dementia over the age of 65 compared with those who were more speedy. <\/p>\n
People with a stronger grip had a 42 per cent lower risk of stroke or a mini-stroke \u2013 known as a transient ischemic attack (TIA) \u2013 over the age of 65, although the risk was not cut at younger ages. <\/p>\n
<\/p>\n
Lead researcher Dr Erica Camargo said this level of testing could be routinely carried out by primary care physicians and GPs. \u2018These are basic office tests which can provide insight into risk of dementia and stroke and can be easily performed by a neurologist or general practitioner,\u2019 she added. <\/p>\n
Participants in the U.S. study were tested for walking speed, hand grip strength and cognitive function, and had brain scans. <\/p>\n
During the follow-up period, 34 people developed dementia and 70 people had a stroke. <\/p>\n

Dr Camargo, of Boston Medical Centre, said: \u2018While frailty and lower physical performance in elderly people have been associated with an increased risk of dementia, we weren\u2019t sure how it impacted people of middle age.\u2019 <\/p>\n
Researchers also found that slower walking speed was associated with lower total cerebral brain volume \u2013 fewer \u2018grey\u2019 cells and poorer performance on memory, language and decision-making tests. Stronger grip strength was associated with larger total cerebral brain volume as well as better performance on cognitive tests asking people to identify similarities among objects. <\/p>\n
\u2018Further research is needed to understand why this is happening and whether preclinical disease could cause slow walking and decreased strength,\u2019 added Dr Camargo. <\/p>\n
Dr Anne Corbett, of the Alzheimer\u2019s Society, said: \u2018Before people take stock in the strength of a handshake or the speed you cross the road, more research is needed to understand why and what other factors are involved. <\/p>\n
\u2018The good news is that there are many things to reduce your risk of developing dementia. <\/p>\n
\u2018We recommend you eat a healthy balanced diet, don\u2019t smoke, maintain a healthy weight, take regular exercise, and get your blood pressure and cholesterol checked regularly.\u2019 <\/p>\n
The research was presented yesterday at the American Academy of Neurology\u2019s 64th annual meeting in New Orleans. Some 820,000 people are affected by dementia in the UK. <\/p>\n
