These patients are characterized by reduced levels of S-adenosylmethionine (SAMe) due to a depression of mitochondrial methylation capacity, and its implementation may improve cognitive performance. Based on the above, it is likely a beneficial effect in the treatment with SAMe also on the quality of the sleep. We report the case of an adult male with DS who received benefit of SAMe administration during OSA treatment with CPAP. We observed a significant improvement of apnea/hypopnea index (AHI), which has never been previously reported in Down individuals. AHI dropped from 51.2 to 17.2 from 0 to 49 months.Keywords: S-adenosylmethionine, Down syndrome, sleep apnea, obstructive, oxidative stress, polysomnography
