Sarcopenia is associated with incident Alzheimer's dementia, mild cognitive impairment, and cognitive decline.

Objective: We examined whether sarcopenia is associated with the occurrence of late-life cognitive impairment.

Methods: Nondemented older adults (N = 1175) underwent annual testing with 17 cognitive tests summarized as a global cognitive score. A composite sarcopenia score was constructed based on muscle mass measured with bioelectrical impedance and muscle function based on grip strength.
