Sleep disorders have many different causes and symptoms. Some people have a hard time sleeping, while others sleep at inappropriate times. Some problems are temporary, while others are chronic.
- Daytime sleepiness even after seven to nine hours of sleep
- Been observed to stop breathing during sleep
Periodic limb movements
- Trouble falling or staying asleep
- Sudden muscle weakness when angry or excited
- Paralysis upon awakening or when falling asleep
- Nightmares or bad dreams
- Acting out dreams
The first step in treating a sleep disorder may require an overnight sleep study known as a polysomnogram. This evaluation includes:
Other types of testing:
- EEG: Monitors brain wave activity to determine sleep stages and awakenings.
- EKG: Records heart activity to monitor for abnormalities.
- EOG: Electrooculography monitors eye movement activity.
- EMG: Electromyography to monitor abnormal limb movements and sleep behaviors.
- MSLT: Monitors sleep onset and sleep stages during four to five naps. A sleep study is done before this test for accurate diagnosis.
- MWT: Monitors ability to stay awake in extreme circumstances.
- CPAP: Oxygen levels and breathing are assessed to determine abnormalities that may indicate a sleep disorder.
