Name a common sleep disorder associated with obstructive sleep apnea.

Snoring is a common symptom associated with obstructive sleep apnea, which is a sleep disorder characterized by repeated pauses in breathing or shallow breathing during sleep. When the throat muscles relax excessively during sleep, the airway can become blocked. This obstruction can result in loud snoring, as the airflow is forced through the narrowed passages. Although snoring alone does not indicate obstructive sleep apnea, it is often present in those who have the condition, making it a notable indicator to consider during evaluations for sleep disorders.

In contrast, conditions such as insomnia, sleepwalking, and night terrors are distinct sleep disorders that do not primarily relate to the breathing issues seen in obstructive sleep apnea. Insomnia involves difficulty in falling or staying asleep, sleepwalking occurs during non-REM sleep typically in childhood, and night terrors are episodes of extreme fear and autonomic arousal during sleep. These disorders do not share the same physiological mechanisms related to airway obstruction that characterize obstructive sleep apnea.
