USA: Results from a systematic review published in the journal Neurology showed that in adults with obstructive sleep apnea (OSA), positive airway pressure (PAP) therapy may delay cognitive decline, however, further research is needed.
Alzheimer's disease (AD) and other dementia forms represent a rising global public health crisis. Owing to the unavailability of treatments to prevent, cure, or slow dementia progression, promising means to modify dementia occurrence or severity could be the identification of treatable risk factors that increase dementia risk, such as OSA.
Against the above background, Monica Moon Shieu, University of Michigan, Department of Neurology, Division of Sleep Medicine, and colleagues systematically reviewed the impact of PAP therapy on the incidence of cognitive disorders and cognitive decline among middle-aged and older adults with OSA.
Based on the findings, the researchers found the following:
· Eleven studies (three clinical trials and eight observational studies) were identified.
· In these studies, 96% participants had OSA (n= 60,840) and n=5,826 had baseline cognitive impairment (mild cognitive impairment [MCI] or AD).
· Of all study participants, n=43,973 obtained PAP therapy, and n=16,397 were untreated or in a placebo group.
· Most studies reported a protective effect of PAP therapy on MCI and AD incidence, e.g., delayed age at MCI onset, reduced MCI or AD incidence, slower cognitive decline, or progression to AD.
"These findings suggest the role of OSA as a modifiable risk factor for cognitive decline. The burden of cognitive disorders on aging adults and their families calls for modifiable risk factors to reduce their impact among adults and their families."
"Future researcher that focuses on PAP interventions as a potential means to alleviate the incidence of cognitive disorders and cognitive decline is needed, particularly among ethnoracial minority groups who have been underrepresented and under-investigated in the extant literature," they concluded.
