Summary

This study looks at whether dopamine levels and certain genes affect the risk and severity of sleep breathing disorders like sleep apnea. Researchers will monitor 100 adults overnight and take blood samples to measure dopamine and check for genetic variations. The goal is to better understand the connection, not to test a treatment.
