The researchers, three of whom have affiliations with UT Dallas’ Center for BrainHealth, also found that a dental device to reduce snoring improves cognitive function in individuals who suffer from mild cognitive impairment. The team’s pilot study included 18 individuals ages 55 to 85 with a history of snoring. Another third had mild cognitive impairment, and another third had Alzheimer’s disease. After the intervention period, cognitive function — especially in the domain of memory — improved in the mild cognitive impairment group and no longer differed from cognitively normal individuals. Alternatives to medicine for treating snoring could help individuals sleep better while also improving their cognitive function.
