Brief Summary
The goal of this prospective cohort study is to study patients referred for sleep study by in-lab polysomnography in the Jordan University Hospital and the Jordan Hospital or with an at-home sleep study kit. The main aims are:
- To prospectively obtain demographic and clinical information of patients referred for a sleep study.
- To determine the diagnostic value of facial discoloration as potential marker for obstructive sleep apnea to increase detection rate for the condition.
- To establish a correlation between obstructive sleep apnea and vasovagal symptoms with resulting increased smoking tendency and study the effect of treatment on the disorders.
- To determine the association between timing of appearance of obstructive sleep apnea symptoms and initiation of smoking.

Study Arms (1)
Patients
Patients referred for sleep study by in-lab polysomnography to enrolled hospitals and those provided with an at-home sleep study kit.
Interventions
Patient's brainwaves are recorded overnight to diagnose sleep disorder.
A machine that uses air pressure to keep breathing airways open while patients sleep.
Patient's brainwaves are recorded overnight to diagnose sleep disorder.

You may qualify if:
- Patients within age limit who agree to participate and sign the consent form.
You may not qualify if:
- Patients with prior diagnosis of obstructive sleep apnea by sleep study.
