Frailty and Primary Sarcopenia: A Review

Area of Science:

• Gerontology
• Geriatrics
• Internal Medicine

Background:

• Aging populations face increased risks of frailty and sarcopenia.
• These conditions significantly impair functional ability and quality of life in older adults.

Purpose of the Study:

• To review the definitions, assessment methods, and management strategies for frailty and sarcopenia.
• To examine the relationship between frailty and sarcopenia in the aging population.

Main Methods:

• Systematic literature search of Medline, Scopus, and Psychoinfo databases.
• Keywords used: frailty, sarcopenia, aging, functional disability.

Main Results:

• Frailty and sarcopenia are clinically assessed using methods like DXA, CT, MRI, bioelectrical impedance, and anthropometry.
• Both conditions involve reduced energy reserves and stress resistance, leading to fatigue, comorbidity, functional decline, and hospitalization.
• The prevalence of combined frailty and sarcopenia is low but requires prompt identification.

Conclusions:

• Frailty and sarcopenia present distinct but overlapping challenges for older adults.
• Early detection and tailored management are essential to mitigate negative health outcomes associated with frailty and sarcopenia.
