Researchers studied nearly 2,800 older adults to see if problems with feeling vibrations in their legs and feet (a sign of PN) were linked to thinking and memory skills. They found that people with worse vibration sensation had lower scores on tests for overall thinking and executive function, and a weaker link with visual memory. These results were the same for people with and without diabetes. This means that trouble feeling vibrations in the legs may be connected to problems with thinking and memory in older adults.
