Sleep Studies

The sleep center at Mobridge Regional Hospital helps individuals with sleep disorders achieve more normal sleep patterns. The Sleep Center provides comprehensive clinical evaluation, diagnosis and management of adolescents and adults with sleep disorders. Our center's services are provided by professionals experienced in sleep-related disorders.

A sleep study (polysomnogram), is an overnight procedure designed to monitor and record the various changes in the body during sleep. Prior to the study, the patient must participate in an evaluation consisting of completing a questionnaire and a history and phsycial exam. A history of sleep patterns and difficulties will be obtained. The patient then retires in a comfortable private bedroom. Recording sensors are applied and a qualified polysomnographic sleep technologist monitors the patient's sleep. The technologist is continuously available should a patient require assistance. Brain waves, muscle activity, body position, breathing, heart rhythm and oxygen levels in the blood are some of the activities monitored during the study. Upon completion of the overnight recordings, the data from the study is reviewed by board certified sleep specialists for interpretation and report.

It is highly recommended that a patient be evaluated by a board certified sleep specialist before obtaining a sleep study, however we do accept referrals from other physicians. We will need pertinent information regarding the patient's problems with sleep as well as recent laboratory informaiton. This information must be less than six months old. You must also have completed a sleep questionnaire concerning your medical, psychological and sleep history. All of this information will be reviewed by our sleep specialists. Initial consultations can be completed by the patient's primary physician. Sleep studies must be ordered by a phsycian.

Restful sleep is very important to your health. Sleep is a timef or the mind and body to renew and restore. It is eastimated that two out of every five Americans have a serious sleep disorder. Excessive daytime sleepiness, falling asleep at inappropriate times and snoring are the predominant symptoms of most disorders.

Common Sleep Disorders

Sleep Apnea & Snoring - periods of interruped breathing, as frequently as several hundred times during sleep. Causes of apnea include a blockage of the upper airway and diseases of the central nervous system. Apnea victims may experience excessive daytime sleepiness, high blood pressure, rapid weight gain, morning headaches, personality changes, impotence, signs of heart failure or enlargement, depression, frequent nighttime awakenings, frequent nighttime urination or bedwetting, and heavy snoring. They may also have sleep attacks during the day, similar to those associated with narcolepsy.

Restless Legs Syndrome - an urge to move legs and/or arms during evening hours due to crawling or restless sensations in the legs and/or arms. This condition may cause insomnia and disrupted sleep.

Periodic Limb Movement Disorder (PLMD)- abnormal limb movement that can cause restless or poor sleep. People with PLMD are often not aware of these movements that may be serious enough to prevent the person from falling asleep or cause difficulty staying asleep. This may cause excessive daytime sleepiness.

 Circadian Rhythm Sleep Disorders- the misalignment between the person's sleep pattern and the sleep pattern that is desired or regarded as the societal norm. In most circadian rhythm disorders, the underlying problem is that the person cannot sleep when sleep is desired or expected. These include Jet Lag Syndrome, Shift-Work Sleep Disorder, Delayed-Sleep Phase Syndrome, Advance-Sleep Phase Syndrome and Irregular Sleep/Wake Pattern.

Narcolepsy- sudden and uncontrollable attacks of excessive sleepiness during the day. This disorder causes an individual to sleep at inappropriate times such as while driving, eating or in meetings. Common complaints include frequent, vivid nightmares or hallucinations upon falling asleep, sudden muscular weakness when angry, surprised or amused and monetary paralysis upon wakening.

Insomnia - difficulty falling asleep and/or remaining asleep.

Parasomnias- undesirable events that include conditions such as somnambulism (sleep walking) and nightmares.

Other disorders- seizures, bruxism (grinding of the teeth) and other conditions that cause improper sleep patterns, as well as sleep disorders in children.
