The Meaning of Dopaminergic Pathway in Sleep Breathing Disorders.

Enrolling by invitation

Conditions studied: Sleep Apnea, Sleep-Disordered Breathing

In brief

The participants in the study will be adult patients with suspected sleep-disordered breathing. A one-night polysomnography will be performed using the NOXA1 device (NOX Medical, Reykjavík, Iceland). During the polysomnographic examination, sleep, breathing, heart rate and activity of the masticatory muscles will be recorded. Blood sample will be taken from each of the participants qualified to the study and control group to determine the level of dopamine and used to perform genetic tests of selected single nucleotide polymorphisms occurring within the genes regulating the concentration of dopamine and genes encoding dopamine receptors.
