Why Do a Sleep Study?

Left untreated, sleep disorders can lead to other conditions such as high blood pressure, heart disease and depression. Sleep studies enable doctors to diagnose and identify treatments for sleep disorders.

A sleep study, or Polysomnography (PSG), is an overnight exam that provides insights into a patient’s brain and bodily functions while they sleep.
