Nocturnal Polysomnogram (NPSG)

Nocturnal Polysomnogram (NPSG) is an all-night sleep study intended to document any respiratory, neurologic or physical problem that may occur during sleep. Oftentimes, these problems may cause either an inability to sleep or excessive daytime sleepiness. Although this test is not a treatment, it can help your doctor determine whether you suffer from a sleep disorder.
