This case report describes a 68-year-old woman with severe sleep apnea (a condition where breathing repeatedly stops during sleep) who also had symptoms of chronic fatigue, daytime sleepiness, and morning headaches. Because she couldn't tolerate the standard breathing mask treatment due to anxiety, she had surgery to widen her airway. After surgery, her sleep apnea improved significantly and her fatigue and other symptoms improved.
For ME/CFS patients, this case is relevant because fatigue is a cardinal symptom, and untreated sleep apnea can severely worsen daytime function and fatigue. Some patients diagnosed with ME/CFS may actually have sleep-disordered breathing as a contributory or primary cause, making surgical evaluation important. Identifying and treating sleep apnea in fatigued patients could potentially improve outcomes in a subset previously labeled as having ME/CFS.
This case report does not prove that sleep apnea causes ME/CFS, nor does it demonstrate that genioglossal advancement is effective for ME/CFS patients generally. The patient's fatigue may have been solely secondary to untreated sleep apnea rather than representing primary ME/CFS. Single case reports cannot establish causation or generalize findings to larger populations.
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 →
The first block is for the primary paper and is the citation you should use in research work. The atlas-snapshot line only applies if you are specifically referring to this atlas’s reading of the paper on the date shown.
