Knowledge gaps surrounding the definition, diagnosis, and management of sarcopenia
While it was initially characterised by a loss of muscle mass, sarcopenia has been defined by several international panels as a decline in muscle function, with a focus on muscle strength and physical performance. Despite the existence of algorithms and research into screening tools for its diagnosis, sarcopenia has not yet been appropriately recognised by the World Health Organisation’s latest version of the ICD (ICD-11), which is used by most countries. Definitions of sarcopenia are growing more precise, yet this does not translate into improved patient care and outcomes.
This article aims to summarise the knowledge gaps surrounding sarcopenia’s definition, diagnosis, and treatment in current clinical practice. It also highlights the next steps in achieving worldwide sarcopenia recognition.
