The patients who happen to have insomnia symptoms, but still, the cause is not so clear, and then the doctors do the overnight sleep study to determine the actual cause and type of insomnia. The people are having symptoms from another sleeping disorder like restless legs syndrome or sleep apnea then the doctors perform a detailed examination of this kind of patient. The patients spend the whole night at a sleep clinic or the sleep center. The doctors perform a series of tests for recording and monitoring the various body activities.
The doctors use a device known as Polysomnogram to measure body activity during the sleeping time of the patient. The recording and monitoring of body activities happen when the person is sleeping. The devices attached to the person records brain waves, heartbeat, breathing, body movements, and eye movements. Then the neuroscience specialist compares these recordings with the different patients to check what the condition of the patient is and what the possible cause of insomnia in the patient is.
