Sleep-disordered breathing is a frequent disorder that affects approximately one quarter of the common population of adults. Numerous studies suggest a tight link between sleep apnea and ischemic stroke as well as between sleep apnea and cognitive impairment. Cerebral hypoperfusion and hemodynamic changes during apneic events could be a key mechanism involved in both processes. In a current paper, we present an overview of dia­gnostic methods that could be potentially used for a blood flow monitoring in obstructive sleep apnea patients. We also report our experience with the use of US tagged near-infrared spectroscopy during overnight polysomnography which was not previously reported in the literature.

The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.

The Editorial Board declares that the manuscript met the ICMJE “uniform requirements” for biomedical papers.
