A comparison of the randomized subjects receiving therapy over the first three-week period did not result in a statistically significant improvement in cognition, although all measures changed in the expected directions.
However, after the placebo group was switched to therapeutic CPAP treatment, the group as a whole showed a significant improvement in cognition after three weeks of treatment.
"The change in scores for individual tests suggested improvements in verbal learning and memory as well as some aspects of executive function such as cognitive flexibility and mental processing speed," said Ancoli-Israel.
The study was published in the Journal of the American Geriatric Society.
