Common symptoms of sleep disorders include loud and/or irregular snoring, excessive daytime sleepiness, depressed or anxious mood, interruptions in breathing during sleep and/or complaints of inability to fall asleep or maintain sleep.
The most common sleep disorders are:

These apneic episodes last from 10 to 120 seconds and may occur as often as several hundred times a night. Symptoms include heavy snoring, fitful and restless sleep, excessive daytime sleepiness, morning headaches, obesity, high blood pressure, and depression.
