Ans. "Circardian sleep disorders" also referred to as "Delayed sleep phase syndrome" is characterized by sleep onset and wake times which are delayed 3 to 6 hours relative to conventional sleep wake times. The clinical picture may be that of sleep-onset insomnia. The patients are unable to sleep at normal times and may report use of sedative-hypnotic drugs, bedtime use of alcohol or even psychtherapy.

Sleepiness is an important factor in many motor vehicle accidents. 4% of all traffic fatalities and as many as 30% on high-speed, boring stretches of highway result from a driver falling asleep at the wheel. Sleepiness has been implicated as a contributing factor to major industrial accidents and environmental disasters such as the Exxon Valdez oil spill. Loud snoring can create a severe strain on a relationship. Imagine sleeping next to a buzz saw every night.

Sleep disorders are common in Alzheimer's disease (AD). Some sleep more (hypersomnia), but less sleep (insomnia) in AD is a larger problem. When the person with AD sleeps less, caregivers also sleep less. Loss of the usual sleep cycle can occur so that the person sleeps during the day and is awake at night. Other sleep problems include restless legs (an unpleasant creeping sensation), loud snoring, irregular breathing and vivid nightmares that disturb the person with AD.

There are four comfortable bedroom-like rooms designed for sleep studies. Each room has a double bed, TV, and a private bath.

The causes of sleep disorders are numerous, and range from environmental factors such as stress, noise, light, or an irregular sleep schedule, to medical factors such as anxiety, depression, menopause, excessive weight, age, pregnancy, central nervous system malfunction, or genetics. In some cases, alcohol, caffeine and other drugs can cause or contribute to a sleep disorder.

The National Commission on Sleep Disorders Research estimates that over 40 million Americans are chronically ill with various sleep disorders, that 38,000 cardiovascular deaths occur annually as a direct result of sleep apnea, yet, "the vast majority of Americans with sleep disorders remain undiagnosed and untreated".

Sleep research is a relatively new field of study that is growing as doctors realize the impact that sleep has on our health. The following findings about sleep disorders have been discovered in the past five years: Hypertension - Two very large studies (the Wisconsin Sleep Cohort Study and the Sleep Heart Health Study) confirm that sleep disordered breathing causes hypertension across all age, gender, and ethnic groups.

Ans. Sleep disorders can generally be diagnosed in a laboratory If a physician finds an evidence of a sleep disorder such as apnea, nacrolepsy, restless leg syndrome then polysomography may be recommended. These studies is conducted generally in a sleep laboratory within a medical center. These studies can be helpful only in some cases of insomnia, as in most of the cases the patient's history taken by the physician can determine the cause or causes of insomnia.

Anyone of any age or gender can have a sleep disorder. However, some people who are more at risk for some sleep disorders include:

A) Most can be successfully treated with medication, light therapy and continuous positive airway pressure (CPAP) devices.

Any condition that creates daytime drowsiness puts you at risk for mistakes and accidents. Every year, more that 100,000 traffic accidents are attributed to sleepy drivers. In addition to causing daytime drowsiness, sleep apnea can also raise blood pressure and put you at greater risk for developing heart disease. Other conditions, such as parasomnias that create unwanted movement during sleep can put you at risk for harming yourself of others.

Most patients who come to the Sutter Sleep Disorders Centers are able to achieve normal or near-normal sleep patterns through a combination of medical treatment, behavior modification and coping skills. Some neurological disorders, such as narcolepsy, can be difficult to resolve fully. In those cases, patients often receive treatment coupled with coping skills leading to improvements that allow greater freedom and more normal function.

Sleep disorders are conditions that prevent a person from getting restful sleep and, as a result, cause daytime sleepiness. There are about eighty different types of sleep disorders and about 70 million Americans suffer from them. Inability to fall asleep or to stay asleep (insomnia) is the most common complaint.

Diagnosis begins with recognition of the possibility of a sleep disorder by patient, bed partner, or doctor. For some disorders such as insomnia or restless leg syndrome, history, sometimes supplemented by other testing or the maintenance of sleep diaries, reveals the problem. For other disorders such as sleep apnea or narcolepsy, the disorder must be confirmed by a sleep study or polysomnogram.

Movement disorders cause people to move their limbs when they sleep, leading to poor sleep and daytime drowsiness. These disorders include restless legs syndrome, or RLS, periodic limb movement disorder, or PLMD, and REM sleep behavior disorder. Often, restless legs syndrome and periodic limb movement disorder occur in the same person.

There are nearly 85 known sleep disorders. Below, you will find a brief description of several common sleep disorders. Keep in mind this is a partial list. If you experience any of the symptoms outlined above, contact your physician or a Sleep HealthCenters facility for a professional evaluation. Insomnia - One in three American adults has trouble falling or staying asleep at night, or wakes up too early in the morning.

Sleep is not merely "time out" from daily life. It is an active state essential for mental and physical restoration. Yet more than 100 million Americans of all ages regularly fail to get a good night's sleep. Some 84 disorders of sleeping and waking harm personal health and quality of life, and endanger public safety by contributing to traffic and industrial accidents.

Walkers, Crew and Super Crew members sleep together in communal indoor spaces. These "overnight sites" are also the evening locations for entertainment and dinner.

Any sleep-related problem can be evaluated. Some common problems include insomnia, which is trouble falling asleep or staying asleep. Some of the more popular causes of insomnia are restless legs syndrome (RLS), medication dependency and anxiety/depression. Another common problem is daytime sleepiness, which may be a result of more serious sleep disorders, sleep apnea and narcolepsy.

This page actually gets pretty in-depth. From the Diseases & Conditions section of the Mayo Clinic's massive online site, this page goes into: Dawn Myers talks about the possibility that some people develop eating disorders as a method of coping with the trauma of child sexual abuse.

One of the most common - and commonly ignored - symptoms of a sleep disorder is snoring. If you snore, you should be evaluated for potentially serious airway obstruction, especially if you have a cardiovascular disease like high blood pressure. You should also get medical attention if your partner sees you stop breathing during sleep.

A) Sleep Apnea, Upper Airway Resistance Syndrome, Snoring, Hypersomnia, Insomnia, Restless Legs Syndrome, Periodic Limb Movement Disorder, Narcolepsy etc.

A sleep disorders evaluation is a medical assessment. It may begin with an office visit where the patient is interviewed by a sleep disorders specialist, or the primary care physician may simply refer the patient for overnight testing. Because the diagnosis of many sleep disorders requires that the patient sleep overnight in the laboratory, the St. Joseph Hospital Sleep Disorders Center provides sleep rooms that are private and comfortable in a hotel-like setting.

The most common sleep disorders among older adults are insomnia, sleep-disordered breathing, such as snoring and sleep apnea, as well as movement disorders like restless legs syndrome.

Ans.Bright light can shift circardian rhythms. It acts on the superchiasmatic nucleus of the hypothalmus via the retinohypothalmic tract to alter the phase or timing of the circardian system. Hence exposure to bright light in the late evening i.e. at the beginning of the sleep cycle promotes sleep.

Due diligence is the discharge of someone's duties, in good faith, in a manner in which that person reasonably believes to be in the best interests of other party and with the care prudent persons in like positions with the same background, experience, expertise and knowledge would exercise under similar circumstances.
