Dissertation: Title: Sleep and Mild Cognitive Impairment Mild cognitive impairment (MCI) is a transitional stage between normal aging and Alzheimer’s disease (AD). Progression from MCI to AD often results in severe decline in everyday function and can lead to institutionalization. Interventions that effectively delay or stabilize cognitive decline and improve everyday function in MCI are critically important. A promising opportunity for stabilizing cognitive decline and improving everyday function in MCI is treatment of comorbid conditions that may accelerate their decline. One such condition is obstructive sleep apnea (OSA). OSA is effectively treated with continuous positive airway pressure (CPAP) therapy. However, many people have difficulty adhering to CPAP therapy at a therapeutic level (at least 4hr/night). There are multiple factors that may contribute to successful adherence of CPAP therapy in persons with MCI. Current dissertation research aims to explore personal, environmental, and social contributors to CPAP adherence in individuals who participated in a larger interventional study aimed at evaluating the impact of CPAP therapy on the progression of neurocognitive impairment over the course of a year in persons presenting with comorbid MCI and OSA.
