Sleep Problems

A good night’s sleep is critical for renewing mental and physical health of every person. Numerous sleep problems (disorders) are conducive to a lowered quality of life and may endanger personal and public safety. Some sleep disorders may be life-threatening. But, sleep disorders are treatable. A sleep study may be necessary to diagnose sleep problems or obstructive sleep apnea. The study is somewhat like spending a night in a hotel with the difference of having sensors attached to one’s body while being watched in a sleep.

Snoring and Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea (OSA) is the repeated collapse of the upper airway. Symptoms of OSA include snoring while sleeping, waking up at night, and tiredness in the morning. Sleep study may be necessary to diagnose the OSA.


Insomnia is trouble falling asleep or staying asleep during the night and may be a symptom of other health problems. Insomnia can be caused by a number of factors including psychological and/or environmental ones, lifestyle, or physical/psychiatric illness.


Narcolepsy is a tendency to sleep at inappropriate times and constant daytime sleepiness. Symptoms include excessive daytime sleepiness, sudden loss of strength in muscles, sleep attacks (sleep paralysis), and continual sleepiness and tiredness that cannot be fully relieved by any amount of sleep.


Parasomnias are abnormal behavioral or physiological events occurring in association with sleep events. They represent the activation of physiological systems at inappropriate times during the sleep-wake cycle. Symptoms of parasomnias include unusual behavior during sleep, for example sleep paralysis, walking around the house while asleep, night terrors, or others.

Periodic limb movement/Nocturnal myoclonus

Periodic limb movement is a condition of RLS that occurs at night, causing brief awakening and sleep fragmentation. The end result of the periodic limb movement is daytime sleepiness or fatigue.

Restless Leg Syndrome

Restless legs syndrome (RLS) is an uncomfortable feeling that occurs in legs when they are still, especially at bedtime. RLS can interfere with travel or the use of transportation. It is important to determine whether there are any conditions (such as iron deficiency, kidney problems, diabetes, arthritis, etc.) which may be contributing to the RLS. Once these are treated or excluded, treatments of RLS include medications and, if necessary, iron supplements.
