Difficulty walking up the stairs , thanks to the onset of a “shuffling” gait, has been linked to increased dementia risk.

And a decline in gait speed alongside cognitive changes has been associated with increased likelihood of developing the condition, too.

Those with Parkinson’s might notice multiple changes to their walking patterns, too, including smaller steps, slower speed, difficulty turning, and feet that land flat rather than on the heel, increasing a person’s risk of falls.

Scientists think that a change to the upper body while walking could reveal early Parkinson’s, too.
