    SPECIAL ISSUE 1: INVITED ARTICLE Sleep Disorders Preeti Devnani ABSTRACT Sleep disorders are an increasingly important and relevant burden faced by society, impacting at the individual, community and global level. Varied presentations and lack of awareness can make accurate and timely diagnosis a challenge. Early recognition and appropriate intervention are a priority. The key characteristics, clinical presentations and management strategies of common sleep disorders such as circadian rhythm disorders, restless legs syndrome, REM behavior disorder, hypersomnia and insomnia are outlined in this review.

  • Ac 120-100 06/07/10
    U.S. Department Advisory of Transportation Federal Aviation Administration Circular Date: 06/07/10 AC No: 120-100 Subject: Basics of Aviation Fatigue Initiated by: AFS-200 Change: 1. PURPOSE. This advisory circular (AC): • Summarizes the content of the FAA international symposium on fatigue, “Aviation Fatigue Management Symposium: Partnerships for Solutions”, June 17-19, 2008; • Describes fundamental concepts of human cognitive fatigue and how it relates to safe performance of duties by employees in the aviation industry; • Provides information on conditions that contribute to cognitive fatigue; and • Provides information on how individuals and aviation service providers can reduce fatigue and/or mitigate the effects of fatigue. 2. APPLICABILITY. This AC is not mandatory and does not constitute a regulation. 3. DEFINITIONS. a. Circadian Challenge. Circadian challenge refers to the difficulty of operating in opposition to an individual’s normal circadian rhythms or internal biological clock. This occurs when the internal biological clock and the sleep/wake cycle do not match the local time. For example, the sleep period is occurring at an adverse circadian phase when the body wants to be awake. Engaging in activities that are opposite of this natural biological system represents the circadian challenge (e.g., night work, shift work, jet lag). b. Cognitive Performance. Cognitive performance refers to the ability to process thought and engage in conscious intellectual activity, e.g., reaction times, problem solving, vigilant attention, memory, cognitive throughput. Various studies have demonstrated the negative effects of sleep loss on cognitive performance. c. Circadian Rhythm. A circadian rhythm is a daily alteration in a person’s behavior and physiology controlled by an internal biological clock located in the brain.

  • Learn About Obstructive Sleep Apnea
    Trouble Staying Fully Charged? Learn About Obstructive Sleep Apnea Has someone told you that you snore loudly at night, keeping other people awake? Maybe someone has told you that they have seen you grunting and gasping for breath during sleep? Have you felt tired during the day no matter how much sleep you think you got the previous night? If you can answer yes to these questions then you may be experiencing the symptoms of Obstructive Sleep Apnea, or OSA for short. What is OSA? OSA is a sleep disorder that results in your breathing being repeatedly interrupted during sleep. OSA occurs when the muscles in the back of your throat relax when you fall asleep, and as a result your airway becomes obstructed. When your airway is partially obstructed you snore loudly. When your airway is completely obstructed you experience a pause in breathing called an “apnea”, which can last 10 seconds or much longer. During an apnea you are not getting any oxygen into your lungs! If you are experiencing an apnea you will eventually awaken from sleep just enough to regain muscle control, gasp and take a series of breaths before falling back to sleep. Once asleep, your throat muscles will relax and you will experience another apnea and oxygen will again be cut off. So you will come back up out of sleep to gasp for air, and this process repeats itself over and over again throughout the night. Each apnea restricts the amount of oxygen you get and each arousal, or short awakening out of sleep, reduces your sleep quality and quantity.

    Stanford Center for Sleep Sciences and Medicine MEDICINE FACULTY SPOTLIGHTS The pace of our lives has never been more intense. It seems our society has become permanently wired into the “on” position, with no dimmer switch in sight. We’re expected to keep up with the latest news, care for our families, stay connected with friends, and remain available to our employers. In this world of hyper-stress and information overload, sleep has become a precious and scarce commodity. Sleep disorders impact more than 60 percent of adults at some point during their lifetime. The price we pay for our lack of sleep is high: it affects the mind as well as the body. Chronic sleep deprivation has enormous medical consequences for cardiovascular, metabolic, and psychiatric conditions.

We coined the term “obstructive sleep an autoimmune disease caused by loss of apnea,” established gold-standard clinical evaluations such as the multiple hypocretin. Dr. Mignot created a database sleep latency test, and discovered the cause of narcolepsy.
