There are more than 84 different types of sleep disorders. Following are a few of the most common:

Restless Legs Syndrome (RLS)

Neurological movement disorder characterized by abnormal, uncomfortable stinging in the legs that typically occurs or worsens when a person is at rest; a near-constant “pins and needles” feeling that results in constant moving of the legs and prevents a restful sleep.

Obstructive Sleep Apnea (OSA)

A disorder that occurs when air cannot flow in or out of a person’s nose or mouth although efforts to breathe continue; caused by mechanical and structural problems in the airway that cause interruptions in breathing (i.e., throat muscles and tongue relax, excessive amount of tissue in the airway); results in choking sensations during sleep and is almost always accompanied by snoring between apnea episodes.


The most common sleep disorder; described as the inability to initiate or maintain sleep and is associated with daytime fatigue and sleepiness; often the result of stress, illness, environmental factors, or other conditions that throw off a normal sleep schedule. It is important to establish Good Sleep Habits as part of your insomnia treatment.


A disorder that manifests itself through excessive daytime sleepiness, uncontrollable sleep attacks and muscle weakness triggered by sudden emotional reactions such as laughter or fear; sometimes accompanied by vivid dreamlike scenes or paralysis upon falling asleep or waking.

Sleep/Wake Cycle Disorders

A disorder accompanied by symptoms of insomnia or sleepiness at inappropriate times; associated with patients who work rotating schedules, suffer from jet lag, or have insufficient sleep syndrome; can become progressive and chronic, but can be treated with medication and therapy.

Chronic fatigue

A disorder that produces an ongoing feeling of tiredness, malaise, sleepiness, boredom, or depression; has various causes and is sometimes associated with a sleep disorder.


A disorder that may include nightmares, chest pain, night terrors, sleepwalking and sleep talking; most common in childhood and sometimes worsens during adolescence and adulthood.
