These are some common sleep disorders, as well as signs that these conditions may be present:

Snoring - loud noises made at night when sleeping that can be caused by obstruction in the nasal passages or narrowing in the back of the throat.

Obstructive Sleep Apnea - a condition that is associated with snoring and difficulty exchanging air while sleeping. Symptoms include excessive sleepiness during the day, memory problems, and early morning headaches. Obstructive sleep apnea is also associated with high blood pressure, heart attacks, and strokes.

Restless Leg Syndrome - this disorder is associated with an irresistable urge to move one's legs while resting or when going to sleep. People also describe aching, ant crawling, and cramping in the legs. These symptoms can be alleviated with walking.


Insomnia - difficulty falling asleep or staying asleep at bedtime. There are many causes of insomnia such as depression, anxiety, pain, drug effects or metabolic disorders (thyroid, heart or lung problems, for example).

Sleep Walking - this is a disorder seen mostly in children and young adults in which one walks about or performs complex acts during a deep stage of sleep. The individual has no recollection of performing these types of behaviors.
