How to Tell If You Have a Sleep Disorder

There are many people that have an undiagnosed sleep disorder. They may feel very sleepy during the day. They may have trouble falling to sleep or staying asleep. Friends or relatives may tell them they look very tired. They may experience mood changes, irritability or become overly emotional. Often they have difficulty paying attention, concentrating, or remembering things that are important.  These are all symptoms of sleep deprivation, and possibly of a sleep disorder.

A person that has an undiagnosed sleep disorder will usually answer the question, “What is the problem with your sleep,” with one of five answers. Those answers will be; “I have trouble falling asleep,” ” I have trouble staying awake,” “I can’t get up in the morning,” “I seem to do strange things in my sleep” or  “I can’t sleep because of my partner.” The particular answer chosen helps to narrow down the possibility of a specific type of sleep disorder.

When someone says “I can’t fall asleep” it can mean several things. There could be a problem when first going to bed, after waking up in the middle of the night, or in the early morning hours.
Many people have the problem of not being able to fall asleep when they go to bed. This is called sleep latency. Sleep latency can be a very serious symptom of certain sleep disorders, including sleep onset insomnia, delayed sleep phase disorder, shift work, restless leg syndrome or paradoxical insomnia. Many times the problem is not being able to stay asleep, which is sleep fragmentation.  Often a person with this complaint can fall to sleep easily when they go to bed, but wake up often throughout the night. Sleep disorders may include sleep maintenance insomnia,  shift work. If a person wakes up very early in the morning and cannot get back to sleep, it could be a sign of advanced sleep phase disorder or sleep maintenance insomnia.

If the answer to the question is “I can’t stay awake” and the person is falling asleep at inappropriate times there may be a  sleep disorder such as narcolepsy , obstructive or central sleep apnea, periodic limb movement disorder, restless leg syndrome, shift work or advanced sleep phase disorder.

Those that say “I can’t get up in the morning” and take an hour or more to fully wake from their sleep may suffer from excessive sleep inertia. They are having difficulty making the transition from sleep to being awake. Sleep disorders that could be responsible for excessive sleep inertia  are sleep apnea and delayed sleep phase disorder.

A person that answers the question with “I do strange things in my sleep” may find that their sleep is full of surprises. Sleepwalking, Sleep terrors, confusional arousals, REM sleep behavior disorder, nightmares, sleep-related eating disorder and bruxism are all types of sleep disorders known as parasomnias.

If a person answers “I can’t sleep because of my partner” snoring, sleep apnea, bruxism, restless leg syndrome, or periodic limb movement disorder may be the sleep disorder to blame.

How would you answer the question of “What is the problem with your sleep?”

A Sleep Disorder That Affects the Legs – Restless Sleep Syndrome

Restless leg syndrome, known as RLS, is a sleep disorder that afflicts more than 15 percent of adults.
It affects more women than men and the incidence of restless leg syndrome increases with age. Certain medical conditions, such as diabetes, arthritis and varicose veins,  also increase the risk of developing restless leg syndrome.

This sleep disorder is characterized by an uncontrollable  urge to move the lower legs, knees and occasionally the arms. Sometimes painful sensations accompany the urge to move. People that suffer from this sleep disorder describe the feelings and sensations in different ways.  Many describe a tingling, itching or pulling sensation. Still others say it feels prickly or burns. Some feel as if they have worms crawling under their skin.

The sensations which are typical of this sleep disorder can occur anytime during the day or night.
Restless leg syndrome occurring at night has a devastating effect on sleep. The symptoms can cause the sufferer to get in and out of bed repeatedly which can delay or disrupt sleep. Since sleep in repeatedly interrupted, extreme daytime sleepiness is common.

The combination of always feeling  tired and the symptoms themselves can cause a person with restless leg syndrome to alter their lifestyle. Long trips, movies, concerts and eating in restaurants are some of the activities they usually avoid. Attending a long meeting at work can become very painful and uncomfortable. People that have this sleep disorder often suffer from depression.

Researchers believe that restless leg syndrome may be caused by malfunctions of the pathways in the brain that controls movement reflexes and sensations. Often this sleep disorder has a genetic base.

Restless leg syndrome cannot be diagnosed by one single test. Often standard neurological examinations show no signs of an abnormality.  In many cases, a doctor makes the diagnosis of restless leg syndrome based on the description of the symptoms. They also take into account family history, and the results of a routine medical examination and blood tests.

Many times the treatment for restless leg syndrome is aimed at controlling the debilitating sensations that accompany this sleep disorder. Often iron supplements are prescribed because severe anemia has been linked to this disorder. Relaxation techniques, diet changes and the elimination of caffeine and alcohol help some sufferers of restless leg syndrome.

In most cases, this sleep disorder is treated with drugs. These drugs could include dopamine agents, benzodiazepines, opioids or anticonvulsants. Medications do not cure restless leg syndrome, but they manage the symptoms. People that suffer from this sleep disorder usually have to stay on their medications for the rest of their lives.

Another sleep disorder similar to restless leg syndrome is periodic limb movement disorder known as PLMD.  There are  two main differences between restless leg syndrome and periodic limb movement disorder. Restless leg syndrome occurs when the sufferer is awake or asleep; periodic limb movement disorder only occurs when the sufferer is asleep.  Restless leg syndrome movements are voluntary responses to very unpleasant sensations; the movements of periodic limb movement disorder are involuntary and are  not consciously controlled. Both of these sleep disorders can be effectively  controlled with medical treatment.
