Images: A disorder-specific CPAP adherence pattern.

UNLABELLED: A patient previously diagnosed with moderate obstructive sleep apnea and treated with continuous positive airway pressure was seen for her yearly routine follow-up. A continuous positive airway pressure adherence report of the previous year revealed periodic usage with almost stable monthly fluctuation between proper and poor adherence. The patient declared consistent usage when sleeping. The patient's sleep habits, such as usual bedtime and start of continuous positive airway pressure treatment, had not changed during the monthly variations. What disorder can explain this continuous positive airway pressure adherence pattern?
