Sleep Apnea/Breathing

Sleep Disorders

Sleep Apnea
Sleep Apnea refers to brief interruptions of breath during sleep. There are two main types of sleep apnea: obstructive sleep apnea (OSA) and central sleep apnea. Obstructive sleep apnea is the most common, where a person has trouble breathing during sleep due to blockage of the airway. Central sleep apnea is where a person repeatedly stops breathing because the brain fails to signal the muscles that control this action. Sleep apnea affects over 18 million people in the United States. Unfortunately sleep apnea is a commonly undiagnosed disorder and therefore often goes untreated. The consequences of untreated sleep apnea can range from mild to severe, including high blood pressure, heart disease, stroke, brain damage, diabetes, depression, obesity, and impotency. Even though it can strike children and adults or either sex, there are certain risk factors to be aware of. Being an overweight male over 40 can significantly increase your chances of developing sleep apnea. The first step of understanding sleep apnea is to recognize any symptoms. Major symptoms include excessive lethargy and sleepiness, snoring, and headaches. Although challenging to live with, sleep apnea can easily be treated.

Insomnia occurs when a person has difficulty falling asleep and/or staying asleep for at least 30 days. There are two types of insomnia, primary and secondary. Primary insomnia means that there is no other health condition that is impacting the lack of sleep. Secondary insomnia means that there are existing health conditions, medications, or substances that are impacting their sleep pattern. An alarming statistic: 1 out of 3 people have insomnia at some point in their lives. If insomnia is left untreated, it can have serious consequences. Overall, sleepiness increases lapses in attention and slows reaction time. If a person is behind the wheel, the effects can be as deadly as one who is impaired by alcohol. Some common causes of insomnia include alcohol and caffeine consumption, anxiety, stress, and depression. Major symptoms of insomnia include difficulty falling asleep, waking often, having trouble getting back to sleep, and feeling tired upon waking up.

Narcolepsy is neurological disorder that affects a person’s ability to sleep and wake normally. People with narcolepsy experience four symptoms: excessive daytime sleepiness, uncontrollable episodes of falling asleep, a sudden loss of muscle tone (cataplexy), and hallucinations. A narcoleptic can fall asleep suddenly, anywhere or anytime, with the episode lasting minutes, or up to an hour. Narcoleptics fall immediately into REM sleep, which for normal sleep cycles, occurs after at least 30 minutes. Narcolepsy affects about 200,000 Americans, but unfortunately, fewer than 50,000 are diagnosed. To find out if you have narcolepsy, or any other sleep related illness, please take our quick and easy online sleep test.

Restless Leg Syndrome
Restless leg syndrome is a disorder where a person must move his/her legs to avoid feelings of unpleasantness. In order to be diagnosed with RLS, one must have all of the following symptoms: strong urge to move the legs which one cannot resist; uncomfortable sensations that are referred to as creeping, crawling, itching, or gnawing; symptoms start/become worse when one is resting and/or lying down; symptoms get better when one moves the legs. RLS affects as many as 10% of Americans, most often in middle-aged adults. Although the cause is unknown, stress definitely makes it worse. Overall, RLS can cause poor sleep quality. This can lead to other issues such as daytime sleepiness, confusion, anxiety, and depression.
