Sleep Apnea

Restless Leg Syndrome(RLS) and Periodic limb movement Disorder

REM sleep behavior Disorder

Sleep ApneaSleep ApneaSleep Apnea is interrupted breathing during sleep.

It usually occurs because of a mechanical problem in the windpipe.

But it also indicates a neurological disorder involving nerve cells (neurons).

Sleep Apnea is interrupted breathing during sleep.

It usually occurs because of a mechanical problem in the windpipe.

But it also indicates a neurological disorder involving nerve cells (neurons).

ProcessProcess1) As people age, muscle tone

relaxes, which may cause the windpipe to collapse.

2) This condition is called Obstructive Sleep Apnea.

3) It results in loud snoring and blocked air flow through the windpipe.

2) This condition is called Obstructive Sleep Apnea.

3) It results in loud snoring and blocked air flow through the windpipe.

4) It lasts from 10 to 60 seconds.

5) People may be gasping or snorting.

6) And then the brain quickly reacts to the sudden lack of oxygen, the muscles tighten.

Why?Why?Narrow nasal passages, enlarged

tonsils, and obesity are factors that

may contribute to obstructive sleep

tobacco, or sedatives.

ResultResultThe sleep cycle can be interrupted as many as 100 times a night.

Every time the windpipe closes, the brain is deprived of oxygen.

Every time the windpipe closes, the brain is deprived of oxygen.

This lack of oxygen eventually can cause problems morning headaches and decreased mental function.

It causes a type of temporary paralysis.

In a person with REM sleep behavior disorder, these signals translate into images that make up dreams.

If the signals are interfered with, the person may physically act out dreams during sleep. For example, if a patient with REM sleep behavior disorder dreams about running, he or she might actually get up and run.

As a result of this condition, patients may injure themselves or others.

BUT !!! REM sleep behavior disorder is rare.
