Are You Feeling Tired? Exhausted? Run Down?

Maybe its your sleep…

Ignoring your sleep disorder can lead to worse things… serious car wrecks, increased risk of heart attack or stroke, diabetes, high blood pressure, and pregnancy complications.  Additional risk factors include symptoms of fatigue, mood swings, obesity, low sex drive, and poor concentration.

Sleep Disorders contribute to a wide range of health problems.

A visit to the sleep specialist is a new experience for most of the patients.

A sleep history is significantly different from the classic medical history that you commonly experienced with your primary care physician.

The sleep history includes detailed information about sleep habits, circadian rhythms, environmental factors (about your bedroom and bed partners), food and beverage intakes, emotional background, intrusive thought processes during the night, and recognition of daytime performance issues like hypersomnolence, fatigue, tiredness and poor concentration and decreased memory capacity, as markers of poor sleep efficacy.



Nocturnal and daytime sleep evaluations are performed with state of the art equipment. The studies are performed at our sleep center. The study is supervised and attended by a sleep technologist and the evaluation is interpreted by the physician.

POLYSOMNOGRAPHY: or sleep study, is a complex evaluation that includes collection of data during sleep. The study can be diagnostic or therapeutic.

  • This evaluation includes measurement of:
  • EMG (electromyography) "muscle tone".
  • Eye movements measurement.
  • Breathing measurement.
  • This includes measurement of snoring, nasal breathing, oral breathing and effort of breathing.
  • Continuous electrocardiogram.
  • Movement sensors and recording.
  • Continuous oximetry.
  • CPAP titration, and more.

If you are a subject for MSLT (Multiple sleep latency test) or MWT (Maintenance of wakefulness test), in between naps you will remain in the dayroom.


  • 10 to 30 % of adults have primary snoring.
  • About 5 % of the adult population suffers from obstructive sleep apnea.
  • The most common symptoms of sleep apnea are loud snoring, excessive daytime somnolence, nocturnal choking or gasping, poor concentration and memory impairment.
  • Due to the hypersomnolence, car accidents are very common in patients with sleep apnea.
  • Primary snoring, increased upper airway resistance and obstructive sleep apnea are closely linked to obesity.
  • Dietary advice and weight loss plays a significant role in the treatment of these disorders.
  • CPAP therapy (continuous positive airway pressure), upper airway evaluation and possible procedures by ENT (ear nose and throat), dental appliances, exercise program are some of the options available for your selection


Things to remember

  • As you arrive to the sleep center, the technician will escort you to your bedroom.
  • You can change to your pajamas or sleep gown.
  • The setup process can take from 45 minutes to one hour.
  • Remember, there is no pain, no needles in this set up process and sleep evaluation.
  • You can get into bed when it is time to sleep.
  • Tell the technician the time that you need to get up.
  • Wake up early enough to shower, get dressed and then you may go.


Sleeping Disorders

Sleep Apnea

Sleep apnea is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. Breathing pauses can last from a few seconds to minutes. They often occur 5 to 30 times or more an hour. Typically, normal breathing then starts again, sometimes with a loud snort or choking sound. Sleep apnea usually is a chronic condition that disrupts your sleep 3 or more nights each week. You often move out of deep sleep and into light sleep when your breathing pauses or becomes shallow. This results in poor sleep quality that makes you tired during the day. Sleep apnea is one of the leading causes of excessive daytime sleepiness. Sleep apnea often goes undiagnosed. Doctors usually cannot detect the condition during routine office visits. Also, there are no blood tests for the condition. Most people who have sleep apnea do not know they have it because it only occurs during sleep. A family member and/or bed partner may first notice the signs of sleep apnea. The most common type of sleep apnea is obstructive sleep apnea. This most often means that the airway has collapsed or is blocked during sleep. The blockage may cause shallow breathing or breathing pauses. When you try to breathe, any air that squeezes past the blockage can cause loud snoring. Obstructive sleep apnea happens more often in people who are overweight, but it can affect anyone. Central sleep apnea is a less common type of sleep apnea. It happens when the area of your brain that controls your breathing does not send the correct signals to your breathing muscles. You make no effort to breathe for brief periods. Central sleep apnea often occurs with obstructive sleep apnea, but it can occur alone. Snoring does not typically happen with central sleep apnea.


Insomnia is a common condition in which you have trouble falling or staying asleep. This condition can range from mild to severe, depending on how often it occurs, and for how long. Insomnia can be chronic or acute. Chronic insomnia means having symptoms at least 3 nights a week for more than a month. Acute insomnia lasts for less time. Some people who have insomnia may have trouble falling asleep. Other people may fall asleep easily but wake up too soon. Others may have trouble with both falling asleep and staying asleep. As a result, insomnia may cause you to get too little sleep or have poor-quality sleep. You may not feel refreshed when you wake up. There are two types of insomnia. The most common type is called secondary or comorbid insomnia. This type of insomnia is a symptom or side effect of some other problem. More than 8 out of 10 people who have insomnia are believed to have secondary insomnia. Certain medical conditions, medicines, sleep disorders, and substances can cause secondary insomnia. In contrast, primary insomnia is not due to a medical problem, medicines, or other substances. It is its own disorder. A number of life changes can trigger primary insomnia, including long-lasting stress and emotional upset. Insomnia can cause excessive daytime sleepiness and a lack of energy. It also can make you feel anxious, depressed, or irritable. You may have trouble focusing on tasks, paying attention, learning, and remembering. This can prevent you from doing your best at work or school. Insomnia also can cause other serious problems. For example, you may feel drowsy while driving, which could lead to an accident.


Narcolepsy is a disorder that causes periods of extreme daytime sleepiness. It also may cause muscle weakness. Rarely, people who have this disorder fall asleep suddenly, even if they are in the middle of talking, eating, or another activity. Most people who have narcolepsy also have trouble sleeping at night.

Restless Legs Syndrome

Restless legs syndrome (RLS) is a disorder that causes a strong urge to move your legs. This urge to move often occurs with strange and unpleasant feelings in your legs. Moving your legs relieves the urge and the unpleasant feelings. People who have RLS describe the unpleasant feelings as creeping, crawling, pulling, itching, tingling, burning, aching, or electric shocks. Sometimes, the feelings also occur in the arms. The urge to move and unpleasant feelings occur when you are resting and inactive. They tend to be worse in the evening and at night and are temporarily relieved in the morning. RLS can make it hard to fall asleep and stay asleep. It may make you feel tired and sleepy during the day. This can make it hard to learn, work, and do your normal routine. Not getting enough sleep also can cause depression, mood swings, or other health problems. Some diseases, conditions, and medicines also may trigger RLS. For example, it has been associated with kidney failure, Parkinson disease, diabetes, rheumatoid arthritis, pregnancy, and iron deficiency. When a disease, condition, or medicine causes RLS, the symptoms usually start suddenly. Medical conditions or medicines often cause or worsen the type of RLS that starts later in life. RLS symptoms often get worse over time. However, some people’s symptoms go away for weeks to months. If a condition or medicine triggers RLS, it may go away if the trigger is relieved or stopped. For example, RLS that occurs due to pregnancy tends to go away after giving birth. Kidney transplants (but not dialysis) relieve RLS linked to kidney failure. Treatments for RLS include lifestyle changes and medicines. Some simple lifestyle changes often help relieve mild cases of RLS. Medicines usually can relieve or prevent the symptoms of more severe RLS. Research is ongoing to better understand the causes of RLS and to find better treatments.
