Sarcopenia in Patients During the Acute Phase of Ischemic Stroke: Multimodal Assessment and Three-Month Functional Outcomes

The objective of this observational study is to determine the prevalence of sarcopenia in patients aged 50 years and older with acute ischemic stroke, to characterize its trajectory during the acute phase using instrumental verification and functional-cognitive assessments, and to evaluate its impact on functional outcome at three months. The main research question is: Is the presence of sarcopenia at admission associated with less favorable stroke outcomes, including higher rates of complications and mortality? Participants receiving standard medical care for acute ischemic stroke will undergo extended functional assessment for sarcopenia, and a subset will additionally undergo cognitive evaluation.
