At baseline, all patients were found equally impaired in verbal memory, with the average verbal memory score being approximately 2 SD below the mean for all participants. Following 3 months of CPAP treatment, 21 percent of poor users, 44 percent of moderate users, and 68 percent of optimal users demonstrated normal memory performance. Compared with poor users, optimal users of CPAP were nearly eight times as likely to demonstrate normal memory abilities. Overall, the average verbal memory score for all patients improved approximately 1 SD.
“Moderate use of CPAP may help, but it might not allow patients to reach their full potential recovery where memory is concerned, especially if memory is impaired at baseline,” said Dr. Aloia. “For patients with OSA, the more regularly and consistently they use CPAP, the better off they will be.” Dr. Aloia believes that getting patients to use CPAP at least 6 hours a night could be a challenge for physicians.
“Our findings also suggest that this optimal level of CPAP adherence is uncommon following 3 months of treatment,” said Dr. Aloia. “We need to find ways of encouraging patients to use their treatment all night, every night in order to optimize treatment response.”
“CPAP has proven to be an effective treatment for patients with OSA, yet adherence to treatment remains poor,” said Mark J. Rosen, MD, FCCP, President of the American College of Chest Physicians. “Physicians should educate their patients with OSA about the importance of using CPAP consistently and discuss ways to overcome obstacles to adherence.”
