The study was conducted by researchers in Australia and published in the journal 'JAMA Network Open'.
It found a connection between slower walking as a person ages and the possibility of developing dementia.
The large study assessed the gait of close to 17,000 people over the age of 65.
For people who walked at least 5 percent slower from year to year the study found that they also seemed to experience slower cognitive processing.
Researchers refer to the combination of symptoms as "dual decliners."
In addition, these people who exhibited dual decliners were the ones in the study most likely to develop dementia.

"Dual decliners had a higher risk of dementia than those with either gait or cognitive decline alone." Dr. Joe Verghese, Albert Einstein College of Medicine, via CNN
Despite the findings of this study and related studies published in the past five years, gait is usually excluded from cognitive assessments.

Some experts say that signs of mild cognitive impairment (MCI) do not necessarily equate to the onset of dementia.
In many cases, the symptoms of MCI may stay the same or even improve, National Institute on Aging, via CNN.
These health experts say that exercise could reverse the trend toward dementia.
