BACKGROUND: Obstructive sleep apnea (OSA) and Alzheimer’s disease (AD) areassociated. OSA doubles the risk of AD. Patients with AD and OSA who receive continuous positive airway pressure (CPAP) therapy experience slower dementia progression. However, patients with AD might be unwilling to undergo OSA assessment and treatment because of their dementia symptoms, poor personal motivation, or insufficient family support. Therefore, we investigated the willingness of patients with AD to undergo OSA examination and treatment.
METHODS: This prospective study collected data from consecutive patients with new diagnoses of AD at Chiayi Chang Gung Hospital from January to March 2021. Sex, age, Mini–Mental State Examination (MMSE) score, STOP-Bang questionnaire score, and willingness to undergo OSA evaluation and treatment were analyzed.
RESULTS: In total, 68 patients (27 male, 41 female) with AD were included. Their mean age was 78.9 (56–93) years, and their mean MMSE score was 17.9 (3–23) points. Their mean STOP-Bang score was 3.49 (range, 1–7), and 75% of the patients scored .3 (representing a high risk of OSA). Among the 51 patients who scored .3 on the STOP Bang questionnaire, only 16 (31.4%) were willing to visit the otolaryngology clinic, and only 3 (5.88%) of them were willing to undergo polysomnography. These three patients had moderate or severe OSA; they were all treated with CPAP for more than 1 month, but only one continued CPAP through 6 months of follow-up.
CONCLUSIONS: Patients with AD dementia exhibit low willingness to undergo OSA evaluation and treatment. Therefore, early detection and treatment of OSA before dementia develops may be a better strategy. Further in-depth research remains to be done. (J Taiwan Otolaryngol Head Neck Surg 2022; 57:167-174)
