Investigating the contribution of tongue strength measurement in determining pre‐clinical Alzheimer's disease pathology in older adults

Abstract

Background: Alzheimer's disease (AD) accounts for 60‐70% of dementia cases. Pathological changes begin 15‐20 years before symptoms appear. Identifying non‐invasive biomarkers to detect these changes are required. Gait speed, hand movements and grip strength have been associated with cognitive decline.
