Nighttime Drama

Tossing and turning for hours, with your eyes wide open, while everyone else is sleeping peacefully is a most undesirable experience. Still, sporadic insomnia lasting a few days is not uncommon, and it is generally related to stress and the ups and downs of life. When insomnia becomes chronic, however, emotional or clinical disorders may be involved, and it is important to seek medical help.

Recognizing the need for help is half the battle of curing a sleep disorder. According to Brazilian neurologist Geraldo Rizzo, 90 percent of insomnia sufferers can be treated successfully.

However, for appropriate treatment to be given, it is important to know exactly what is causing the insomnia. A medical examination called a polysomnogram has contributed to the diagnosis and treatment of many sleep disorders.

One of the most common causes of chronic insomnia among adults is related to snoring. If you have ever slept near someone who snores, you know that this can be extremely uncomfortable. Snoring can be a symptom of obstructive sleep apnea syndrome (OSAS), in which the closure of the throat temporarily prevents a sleeper from sucking air into his lungs. Initial steps in treating OSAS include weight loss, avoidance of alcoholic beverages, and avoidance of muscle-relaxant drugs. Specialists may also prescribe specific medication or the use of dental appliances or a continuous positive airway pressure machine.

In more severe cases, surgical correction of the throat, jaw, tongue, or nose may be necessary in order to make it easier for air to enter and leave during the breathing process.

Children can also suffer from insomnia. The signs of sleep deprivation may appear at school—poor scholastic achievement, irritation, lack of concentration—perhaps leading to a wrong diagnosis of hyperactivity.

Some children fight sleep, preferring to sing, talk, or listen to someone telling stories—anything instead of going to bed. This may just be a ruse to get parental attention. In some cases, however, a child may be afraid to sleep because of frequent nightmares related to horror movies, violent news programs, or quarreling in the home. By promoting a peaceful and loving atmosphere at home, parents can help to avoid these problems. Obviously, medical advice should be sought if symptoms persist. Without a doubt, a good night’s sleep is as important for children as it is for adults.

Diagnosing Sleep Disorders

A polysomnogram is a group of tests performed to map sleep while the patient is sleeping under the most normal conditions possible. The following are the basic elements necessary for an evaluation.

• Electroencephalogram—The tracing of electrical activity in the brain, used to classify and quantify the various stages of sleep.
• Electrooculogram—Records eye movements observed during REM sleep.
• Electromyogram—Used to monitor the tonus of chin and leg muscles during REM sleep.
• Electrocardiogram—Used to monitor heartbeat throughout the night.
• Respiratory airflow and movements—Measured by recording the flux of air through the nose and the mouth as well as the movement of the abdomen and the thorax.
• Oxyhemoglobin saturation—Measurement of the level of oxygen in the blood vessels determined by means of a device called an oximeter, attached to the patient’s finger.
