Medical indications of polysommnography in clinical practice

While combining specific brain activities, sleep actively interacts with many central and peripheral systems and body functions. Hence, sleep disorders often present as chronic and comorbid conditions. Given the ubiquity of sleep-related complaints in clinical practice, it appears that sleep disorders can be suspected by a wide range of medical practitioners. This is particularly true for specialists treating patients with chronic and/or comorbid clinical conditions (i.e. internistic disciplines, neurology, psychiatry, physical medicine, ENT and general practitioners). In addition, given that our patients are sometimes unnecessarily conveyed between care providers, it seems appropriate to remind the practical interests and clinical indications of polysomnography.
