What is a sleep disorder?

If you suffer from a sleep disorder, the odds are you don’t know it unless your bed partner has complained to you. Your bed partner probably will see the symptoms before you do. Symptoms can include:

  • Periods observed by your bed partner during which you stop breathing
  • Snoring
  • Excessive daytime sleepiness
  • Fatigue
  • Loss of concentration
  • Irritability
  • Morning headaches
  • Restless sleep
  • Frequent nighttime urination
  • Falling asleep at inappropriate times
  • Frequent awakening
  • Involuntary night time leg movements

Are sleep disorders serious?

Nearly one out of every 10 Americans experiences chronic, debilitating and perhaps life-threatening sleep disorders. Obstructive Sleep Apnea (OSA) is one of the most common sleep disorders. Sleep apnea refers to episodes during which you stop breathing for 10 seconds or longer. You can do this hundreds of times each night without being aware of the episodes. When you suffer from sleep apnea, oxygen levels in the body fall and sleep may be disrupted by arousals. Loud, irregular snoring is usually the most noticeable sign of this disorder. OSA has been associated with high blood pressure, headaches, coronary heart disease, myocardial infarction (heart attack), chronic fatigue and even death. It can become more severe over time.

What is a sleep study?

sleep studyPacific Pulmonary Medical Group Sleep Center offers the latest technology in diagnosing sleep disorders in a comfortable setting. During an overnight sleep study (polysomnogram), different electrodes are placed to connect you to monitoring equipment that will record brain activity, eye movements, and muscle activity. Additional sensors are placed around the nose, chest, and abdomen to record breathing patterns. On the night of the study, you will be asked to come by our sleep center between 8:00pm and 9:00pm to prepare for the test. You will be allowed to go to sleep at your usual bedtime in a private sleep room. If no other tests are scheduled, you will be free to leave the center in the morning between 6:00 and 7:00am.


Types of Sleep Disorders

  • Insomnia – Characterized as difficulty falling or staying asleep, which is often a symptom of a separate issue and can be caused by a number of factors.
  • Narcolepsy – Defined as episodes of excessive drowsiness during the day with a tendency to sleep at inappropriate times.
  • Obstructive Sleep Apnea Syndrome – Indicated by extremely loud snoring for about 5 percent of particularly overweight, middle-aged men.
  • Restless Leg Syndrome – A neurological disorder characterized by an irresistible urge to move one’s limbs, which disrupts an individual’s ability to stay asleep at night and function normally during the day.
  • REM Sleep Behavior Disorder – Rapid Eye Movement (REM) is a naturally occurring sleep phase and this disorder relates to abnormal behavior during REM sleep. Behavior is often in response to the content of the individual’s dreams while sleeping.
  • Sleep ApneaBreathing stops temporarily during sleep, sometimes associated with loud snoring, restless sleep, and gasping for air. Sleep apnea can increase your risk for high blood pressure, heart attacks, diabetes and stroke.
  • Sleepwalking -This parasomnia behavior tends to affect children and sometimes adults. Sleepwalking can be caused by an underlying sleep disruption, which can be dangerous to patients or their bed partner. Evaluating underlying causes of sleepwalking is important in treating this medical condition.
