Validation of SARC-F-Proxy for the Screening of Sarcopenia in Older Patients with Cognitive Impairment.

Objectives: The SARC-F is a validated questionnaire for the screening of sarcopenia in an older population. However, the clinical relevance of this self-reported questionnaire in patients with cognitive problems is questionable. This study aims to validate the SARC-F-Proxy as an alternative screening tool for sarcopenia in patients with cognitive impairment.
