Abstract
Stroke is one of the most common causes of disability in adults. Sarcopenia is a syndrome characterized by progressive systemic muscle loss and functional decline. The decrease in skeletal muscle mass and muscle function throughout the body after stroke cannot be explained by neurological motor disorders due to brain injury alone, it is considered to be a secondary sarcopenia known as stroke-related sarcopenia. Mounting evidences showed that stroke-related sarcopenia might promote the occurrence and development of sarcopenia through various pathogenesis such as muscle atrophy, dysphagia, inflammation, and malnutrition, etc. At present, the main indicators used to assess malnutrition in patients with stroke-related sarcopenia include temporalis muscle thickness, calf circumference, phase angle, geriatric nutritional risk index and mini-nutritional assessment short-form, etc. Currently, there is no particularly effective method to curb its progression, but supplementation with essential amino acids, whey protein combined with vitamin D, high energy diet, avoiding Polypharmacy, as well as increasing physical activity level and reducing sedentary lifestyle may improve the malnutrition status of stroke patients, and increase the muscle mass and skeletal muscle index, further delay or even prevent the development of stroke-related sarcopenia. This article reviews the latest research progress on the characteristics, epidemiology, pathogenesis and the role of nutrition in stroke-related sarcopenia, so as to provide reference for the clinical treatment and rehabilitation of stroke-related sarcopenia.
