Five studies presented at the Alzheimer’s Association International Conference in Vancouver this month provide striking evidence that when a person’s walk gets slower or becomes more variable or less controlled, his cognitive function is also suffering.

Thinking skills like memory, planning activities or processing information decline almost in parallel with the ability to walk fluidly, these studies show.

In other words, the more trouble people have walking, the more trouble they have thinking.

“If gait begins to deteriorate, we begin to have a conversation about how is your memory.”
