Research advances on the correlation between mild cognitive impairment and sarcopenia
Mild cognitive impairment(MCI)is a transitional stage of cognitive abnormality between the normal cognitive function level and dementia,often involving impairment in one or more cognitive domains.Sarcopenia is a type of progressive and common skeletal muscle disorder and may increase the occurrence of adverse outcomes such as falls,bone fractures and frailty in older adults.Both cognitive dysfunction and sarcopenia are among common geriatric syndromes.Studies in recent years have found that the presence of sarcopenia may increase the occurrence of cognitive dysfunction.This article discussed the epidemiological characteristics and diagnosis of MCI and sarcopenia,the possible relationship between them,and potential mechanisms underlying the interaction between them.
