This review article helps doctors understand fatigue in older adults by explaining three types: fatigue that comes on recently, fatigue that lasts a long time, and chronic fatigue syndrome. The article discusses how doctors can evaluate fatigue and offers both medication and non-medication treatments like exercise, vitamins, diet changes, and behavioral strategies.
Understanding how fatigue is classified and managed in older adults provides context for ME/CFS diagnosis and treatment, particularly since ME/CFS patients often experience age-related complications. The review's inclusion of CDC diagnostic criteria and comprehensive treatment approaches helps distinguish ME/CFS from other fatigue conditions that are common in aging populations.
This review does not establish efficacy through controlled trials—it synthesizes existing knowledge rather than presenting original research data. The article does not differentiate between post-exertional malaise (a hallmark of ME/CFS) and general fatigue in older adults, nor does it prove that the same treatments are equally effective across different fatigue categories.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
