Elderly’s Faltering Walking Pace Could Signal The Onset Of Mild Cognitive Impairment

Researchers found that changes in walking speed in late life may signal the early stages of mild cognitive impairment (MCI).

A new study has found that a slowing of walking speed among elderly people could be a sign of the early onset of dementia or MCI.

The study involved 93 people age 70 or older who lived alone. Of those, 54 participants had no cognitive impairment, 31 had non-memory related MCI and eight had memory-related MCI.

The study linking a slowing of walking pace to dementia was carried out by Dr. Hiroko Dodge, of Oregon Health and Science University in the United States.

Dr. Dodge, used a new technique that included installing infrared sensors in the ceilings of homes, a system designed to detect walking movement in hallways.

They were placed in groups of slow, moderate or fast based on their average weekly walking speed and how much their walking speed fluctuated at home.

They were given memory and thinking tests and had their walking speed monitored at their homes unobtrusively over a three-year period.

The study found that people with non-memory related MCI were nine times more likely to be slow walkers than moderate or fast walkers and the amount of the fluctuation in walking speed was also associated with MCI.

Dr. Dodge has suggested that ‘further studies need to be done using larger groups of participants to determine whether walking speed and its fluctuations could be a predictor of future memory and thinking problems in the elderly.’

‘If we can detect dementia at its earliest phases, then we can work to maintain people’s independence, provide treatments and ultimately develop ways to prevent the disease from developing,’ according to Dr. Dodge.
