Washington: How a person walks can be a clue to whether he has Alzheimer`s, after researchers found a link between the disease and a person`s gait. Subtle changes in the way a person walks can be an early warning sign of cognitive decline and a signal for advanced testing, according to research released at the Alzheimer`s Association International Conference in Vancouver, Canada. The findings are the first to link a physical symptom to the disease, which up until now, required doctors to begin a diagnosis by focusing on cognition and administering lengthy neurological exams, `USA Today` reported. They observed that walking changes can occur even before cognition decline surfaces. "Monitoring deterioration and other changes in a person`s gait is ideal because it doesn`t require any expensive technology or take a lot of time to assess," Bill Thies, chief medical and scientific officer for the Alzheimer`s Association was quoted as saying by the paper. "Walking and movements require a perfect and simultaneous integration of multiple areas of the brain," Rodolfo Savica, author of a study done at the Mayo Clinic, said.
