Neurodiagnostic & Sleep Disorder Center

Sleep hygiene is defined as ‘the conditions and practices that promote continuous and effective sleep.'

Good sleep hygiene includes:

  • Regular bedtime and rise time
  • Standard amounts of sleep
  • Restriction of alcohol and caffeine before bedtime
  • Adequate exercise and nutrition
  • Environmental factors that enhance restful sleep, such as a dark and quiet bedroom and a comfortable bed
When you don't get enough sleep, your whole life is affected. Being tired can cause motor vehicle accidents, injuries, personality changes, and irritability. If you feel you aren't getting enough sleep and experience excessive daytime sleepiness, you may be suffering from a sleep disorder. Your doctor may refer you to a sleep study.

Sleep Studies at Western Plains

The Neurodiagnostic and Sleep Center at Western Plains Medical Complex performs sleep studies (polysomnography) to aid in the identification and treatment of sleep apnea and other sleep disorders.

During a polysomnography study, you stay overnight (8:30 p.m. to 6 a.m.) in a comfortable room at the hospital. A technician attaches sensors to your head, chin, throat, chest abdomen, and legs to monitor your sleep from another room. State-of-the-art EEG (electroencephalogram) and other equipment monitors and records your reaction to sleep including:

~ Brain waves  ~ Eye movements
~ Breathing  ~ Heart rate
~ Muscle activity  ~ Oxygen level

Sleep disorders encompass difficulties with sleep and staying awake and include behaviors that cause difficulties with sleep in all age groups from neonatal to the elderly. Types of sleep disorders include:

Advanced Sleep Phase Syndrome (ASPS)

This syndrome is more common among older adults and has only recently been recognized as a significant problem. Sleepiness usually begins in the early afternoon and sufferers often wake up too early and then aren't able to go back to sleep.

Bruxism (Parasomnia)

Teeth grinding during sleep. It tends to effect men and women equally. Bruxism peaks at adolescence.

Delayed Sleep Phase Syndrome (DSPS)

Some people find that they are not able to fall asleep until 2 or 3 a.m. and that they then have trouble waking up in time for work or school. Few lifestyles allow for this kind of sleep/wake schedule. This problem, which is more common in young adults than in other age groups, can interfere with employment and school and can lead to psychological stress.


This is the inability to initiate or maintain sleep. Onset insomnia is having difficulty falling asleep while maintenance insomnia is waking up frequently during the night or waking up too early in the morning with difficulty getting back to sleep.


Patients exhibit attacks of severe daytime drowsiness and decreased daily function and may experience muscle weakness with emotion or they wake up and are unable to move (sleep paralysis).

Nocturnal Seizures

Seizures are described as repetitive, inappropriate behaviors. According to some estimates, seizures occur during sleep or on arousal from sleep in nearly 50% of epileptics, and it is not unusual for seizures to occur only during sleep.

REM Behavior Disorder (RBD)

Normally people are unable to move during REM (Rapid Eye Movement) sleep. People who suffer from RBD do not become "paralyzed" during REM sleep like everyone else. Muscle inhibition in REM is absent in this disorder. Those who suffer from RBD move vigorously during dreaming sleep and may unintentionally cause harm to themselves or others.

Restless Leg Syndrome (RLS)

People experience restless legs in many different ways, but all describe very unpleasant "creepy, crawly" sensations that occur in the legs when they are sitting or lying still, especially at bedtime. If you have RLS, you know it is not the pain of a leg cramp or the numbness someone feels if their leg "falls asleep". RLS sensations are also different from the "pins and needles" or burning feeling a person with diabetes may experience. The uncomfortable feelings of RLS appear most often in the calves of the legs and are temporarily relieved by stretching or moving the legs.

Sleep Apnea

Is defined as the cessation of breathing during sleep. People with sleep apnea are unable to get oxygen their bodies require, which prevents them from getting a restful night's sleep. Untreated, sleep apnea may result in high blood pressure and/or other cardiovascular diseases, strokes, memory loss, weight gain, impotence, and headaches. There are three types of sleep apnea: obstructive, central, and mixed.

Obstructive – Is the most common form and is caused by tissue collapsing in the back of the throat and blocking the airway. The sleeper tries to breathe, but no air can pass into or out of the lungs because of the blockage. Breathing resumes after the person awakens, gasping and struggling for air. Episodes of apnea can last anywhere from 10 seconds to over a minute and may occur several hundred times during the night.

Central – The airway stays open but the brain forgets to tell the muscles that control breathing to keep working.

Mixed – A combination of obstructive and central sleep apnea.

Sleep Terrors

Are different from nightmares because the frightening dreams are not remembered. Sleep terrors usually occur in the first third of the night due to the stage of sleep they occur in. Patients wake up panicked and the arousal from sleep often occurs by hearing themselves screaming or crying out. They wake up feeling terrified but do not recall why. This sleep disorder is predominantly found in children because of the amount of time spent in this sleep stage decreases with maturation.


This disorder is normally found in children and most patients will outgrow this disorder. In sleepwalking the patient is not dreaming and has no recollection the following morning. Sleepwalking usually occurs in the first third of the night and it is very difficult to wake a person up who is sleepwalking.

You will need a physician's order to have a sleep study. Click here to print and complete a Physician Sleep H&P and Study Request.

Once you have been scheduled for a sleep study, please follow these simple instructions:
  1. Bring an overnight bag including sleep clothes, medications to be taken, and any toiletries needed
  2. Do not eat or drink anything with caffeine including chocolate, coffee, tea or soda 6 hours prior to your study time. You should eat your regular breakfast, lunch and dinner.
  3. Do not take any naps the day of your study.
  4. You should take a shower, and wash and dry your hair the day of your study. Please do not use any hair styling products or oils.
  5. If you choose, you may bring your own pillow or blanket.

Follow-up for Sleep Studies results

Our sleep specialist, Dr. Lakin, will interpret your sleep study. You may choose to follow-up with him or with your attending physician to obtain the results of your test.

EEGs assist physicians in the diagnosis of a variety of neurological problems from the common headache and dizziness to seizure disorders, strokes, and degenerative brain diseases.

Follow-Up for EEG results

A neurologist will interpret your EEG and the results sent to your attending physician. You will need to make an appointment with your attending physician to obtain the results of your test.

Should you have any questions or concerns, please consult your physician.
