A polysomnogram is an overnight sleep study that records brain
activity, eye movements, heart rate,blood pressure, oxygen levels, body
movement, and more.
Polysomnograms are used to help diagnose a wide variety of sleep
disorders including: breathing disorders such as obstructive sleep
apnea, sleep related seizure disorders, movement disorders, etc.
Tests usually begin around 9 p.m. and concludes the following

lying in bed awake or asleep shows no noticeable difference in a
For those of us that are conscious of the cost of an in-lab sleep
study, almost all insurances cover sleep studies. According to our
research, insurance providers may require a home sleep test
before conducting a more accurate in-lab test.
