Zusammenfassung:Study Objectives: Obstructive sleep apnea (OSA) increases the risk of developing dementia. Home sleep apnea testing (HSAT) is a convenient and validated method to screen for OSA among cognitively well individuals; however, it is unknown if it is a clinically feasible and practical approach in clinic patients with cognitive impairment. We evaluated if HSAT was a feasible and practical approach to screen for OSA in clinic patients with cognitive impairment. Methods: Patients with cognitive impairment due to neurodegenerative and/or vascular etiologies completed OSA screening using HSAT. HSATwas considered a feasible technique if >= 80% of those who attempted HSAT obtained analyzable data (ie, >= 4 hours of flow, effort, and oxygen evaluation), and a practical technique if = 50% of all patients approached for study inclusion obtained analyzable data. Results: Of the 119 patients who were approached for participation, 83 were enrolled and offered HSAT; 5 did not complete HSATscreening, and the remaining 78 patients attempted HSAT; mean age (+/- standard deviation) of 72.86 (+/- 9.89) years and 46% were male. In those that attempted HSAT, 85.9% (67/78) obtained analyzable data and 56.3% ( 67/119) of eligible patients approached for study inclusion obtained analyzable data. Conclusions: HSAT is a feasible and practical technique in a clinic population with cognitive impairment. As OSA is a modifiable risk factor for patients with dementia, HSAT has the potential to lead to expedited treatment for OSA, which may potentially improve health-related outcomes such as cognition.
