title: [Transdisciplinary approach for sarcopenia. Sarcopenic Dysphagia].
abstract: Sarcopenic dysphagia is difficulty swallowing due to sarcopenia of generalized skeletal muscles and swallowing muscles. Presbyphagia refers to age-related changes in the swallowing mechanism in the elderly associated with a frailty in swallowing. Presbyphagia is different from dysphagia. The most common cause of dysphagia is stroke. However, sarcopenic dysphagia may be common in the elderly with sarcopenia and dysphagia. Frail elderly with aspiration pneumonia can simultaneously experience activity-, disease-, and nutrition-related sarcopenia of generalized skeletal muscles and swallowing muscles, resulting in the development of sarcopenic dysphagia. Consensus diagnostic criteria for sarcopenic dysphagia were proposed at the 19th Annual Meeting of the Japanese Society of Dysphagia Rehabilitation. The concept of rehabilitation nutrition as a combination of both rehabilitation and nutrition care management is useful for treatment of sarcopenic dysphagia. Therapy for sarcopenic dysphagia includes dysphagia rehabilitation, nutrition improvement and sarcopenia treatment. The core components of dysphagia rehabilitation are oral health care, rehabilitative techniques, and food modification. Nutrition improvement is important, because malnutrition contributes to the etiology of secondary sarcopenia and sarcopenic dysphagia. Assessment of the multi-factorial causes of primary and secondary sarcopenia is important because rehabilitation nutrition for sarcopenia differs depending on its etiology. Treatment of age-related sarcopenia should include resistance training and dietary supplements of amino acids. Therapy for activity-related sarcopenia includes reduced bed rest time and early mobilization and physical activity. Treatment for disease-related sarcopenia requires therapies for advanced organ failure, inflammatory disease, or malignancy, while therapy for nutrition-related sarcopenia involves appropriate nutrition management to increase muscle mass.
