Types of Sleep Disorders

Sleep Apnea, Periodic Limb Movements (PLMs), Narcolepsy


Sleep Apnea - Loud snoring, stops breathing, gasping for breath, morning headaches, daytime sleepiness

Periodic Limb Movements - Trouble getting to sleep, legs feel like the skin is tingling when trying to get to sleep, restless sleep, awakenings at night, daytime sleepiness.

Narcolepsy - Receive a normal overnight sleep but still have daytime sleepiness

Risk Factors

Sleep apnea - If the condition is severe, you are three times more likely to have a heart attack or stroke. People with sleep apnea are more likely to have car accidents and work-related accidents due to drowsiness. You can develop other medical conditions.

Periodic Limb Movements - You can have car accidents and work-related accidents due to drowsiness


A diagnostic sleep test will be performed called a Polysomnogram (PSG). This test records your normal sleep. We are looking to see what quality of sleep you are experiencing and if there is anything interfering with your sleep.

A CPAP Titration Test is performed on people who have sleep apnea. In sleep apnea, the patient's throat closes up and air cannot get into their lungs. The brain then arouses the patient from sleep to get the body to start breathing again. This is a test where we give the patient air to help them breathe continuously throughout the night.

A Multiple Sleep Latency Test (MSLT) is used to test how sleepy a patient is during the day and to test for narcolepsy. The patient takes five naps during the day; we are testing to see how long it takes the patient to fall asleep and how deep their sleep is.

Maintenance of Wakefulness Test (MWT) is the opposite of an MSLT. The patient is tested five times during the a dark, quiet room and we are testing to see how long they can stay awake.
