There are several reasons which may lead to the necessity for Sleep Disorder Tests to be conducted. There are many sleep disorder conditions that can only be identified by the appropriate analysis of your sleep pattern by a qualified professional. Many time patients can abruptly wake up as if in a terror or other symptoms such as seizures and periods of gaps in breathing can occur. All these can require Sleep Disorder Tests such as a sleep hygiene test, sleep apnea study, multiple sleep latency test or polysomnogram or sleep study. Most of these tests are behavioral in nature.
