Poor Sleep Habits
Poor sleep habits (referred to as hygiene) are one of the most common problems
encountered in our society. We stay up too late and get up too early. We interrupt
our sleep with drugs, chemicals, work, and we overstimulate ourselves with late-night
activities such as television. Click here to for
more information on sleep hygiene, which may provide useful tips on attaining
a normal night's sleep. Many of the tips in this site are "common sense,"
but it is surprising how many people fail to follow these.
Insomnia is the inability to sleep or inability to sleep well at night. Many
different medical and mental health problems cause insomnia. Insomnia may be
situational, lasting a few days to weeks, or chronic, lasting for more
than 1 month.
Around 9-12 percent of the American population report chronic insomnia. In
severe cases, patients experience fatigue, sleepiness, difficulty concentrating
and difficulty with thinking. Many sufferers feel that they have been robbed
of the joy of life. Insomnia may be a symptom of breathing problems at night
like sleep apnea, of medical illness like heart failure, a side effect of medications,
or a symptom of severe anxiety or depression illness.
While short-lasting insomnia periods are well treated with medication, chronic
or long-lasting insomnia may not respond well to medications. Thus, throwing
sleeping pills at many patients with chronic insomnia is not an effective way
to treat the problem.
An evaluation by the patient's personal physician or a sleep specialist often
helps get to the root of the problem. Many patients respond well to what is
called "cognitive behavioral therapy." In this form of therapy, incorrect
ideas about sleep are corrected. In addition, relaxation and behavioral techniques
may be used to help patients fall asleep. This combined with treatment of any
underlying disorders is often the best way to treat the devastating symptom
of insomnia. Click here for more information
on treatments for insomnia.
Sleep apnea is a common and potentially devastating sleep disorder. It
is the most common reason that patients are referred to sleep centers
around the country.
The word apnea means "not breathing." Patients with
the usual form of sleep apnea actually close off their airway at night.
This airway closure occurs either behind the tongue or behind the nose. Patients continue to make efforts to breathe. Then after 10 to 120
seconds, the brain, realizing it is not getting any oxygen, actually "wakes
up." The brain then tells the upper airway to open to let some air in.
This is associated with loud bothersome snoring, often described as snorting
and gasping. Patients may take a few breaths of air, the brain goes to sleep
again and the cycle may repeat itself several hundred times a night. Patients
are often not even aware that they are doing this (although the bed partner
Sleep apnea is dangerous, common, relative easy to diagnose, and treatable.
Patients with sleep apnea are at great risk for heart disease, heart attacks,
strokes and high blood pressure. In addition, since the sleep is poor quality
(remember the brain keeps waking up), patients are often sleepy during the day.
Sleepiness is associated with inability to concentrate, remember or think. There
is also increased risk in falling asleep while doing vital tasks such as driving
or using heavy machinery.
Medical treatment involves weight loss if the patient is overweight, avoidance
of drugs, which increase the risk of apneas such as sleeping pills, alcohol
and sedative medicines, and sometimes sleeping semi-upright. However, in most
cases additional treatment is warranted.
In some cases we use Continuous Positive Airway Pressure (CPAP for short) to
treat patients. For this treatment a mask is fit over the nose or over the nose
and mouth. The mask is pressurized slightly to hold the airway open and allow
the patient to sleep normally. Newer technology has made the masks relatively
comfortable to use.
Some patients may be candidates for surgery on the upper airway. In the usual
upper airway surgery the uvula (that punching bag in the back of the throat)
and some of the surrounding soft tissue is removed to enlarge the air passage.
In other cases a dental device designed to move the lower jaw down and outwards
slightly may be worn at night.
In a few cases, treatment is begun with an emergent tracheostomy when sleep
apnea is considered to be immediately life-threatening. The decision about which
form of treatment to use should be decided by the patient and his/her physician
on the basis of the sleep studies and rest of the clinical data.
Narcolepsy is a chronic sleep disorder that commonly begins during adolescence
and is characterized by excessive daytime sleepiness with the occurrence of
sleep attacks. Narcolepsy can run in families, but can occur in the absence
of any family history as well. There are several other characteristic symptoms
that may or may not be present, including cataplexy, sleep paralysis and hypnogogic
Cataplexy is the sudden loss of muscle tone, commonly associated with strong
emotions. It may be a subtle sensation of weakness or a complete loss of strength
with a fall to the ground.
Sleep paralysis is a sensation of not being able to move on waking, usually
for a few seconds.
Hypnogogic hallucinations are very vivid and sometimes violent or bizarre
sensations, almost dreamlike, that occur on waking or falling asleep.
The treatment of narcolepsy and its associated symptoms commonly requires a
combination of behavioral modification and drug therapy. Many patients with
narcolepsy will do well with naps scheduled at specific times during the day.
Stimulant medication may be used to alleviate symptoms of daytime sleepiness.
Other medications, such as certain anti-depressants, are used to treat cataplexy.
A new promising treatment for cataplexy using a drug called sodium oxybate has
recently become available. Treatment for each patient must be individualized
and each patient with his/her physician needs to discuss this on a case-by-case
Restless Legs Syndrome and Periodic Limb Movement Disorder
Restless legs syndrome (RLS) is characterized by an intolerable, internal itching sensation occurring in the lower extremities that causes an almost irresistible urge to move the legs. The sensation is commonly described as a "creepy" or "crawly" sensation and is typically relieved by movement of the legs or walking around. When movement stops, however, the sensations frequently return. The abnormal sensations are more common in the late afternoon or evening hours.
In some patients, this problem persists into the nighttime and may prevent
patients from getting a restful night's sleep. Pregnancy and iron deficiency
are associated with an increased frequency of this disease. In many patients,
RLS is extremely distressing. Further, RLS is more common than previously thought,
affecting 5-10% of adults and increasing with age.
Almost all patients with restless legs syndrome have a problem called period limb movement disorder. In this, there are leg (sometimes arm) movements occurring at regular intervals during the night. These movements may fragment sleep, leading to poor quality, non-refreshing sleep. Periodic limb movement disorder can also occur as an isolated problem, often reported by the bed partner.
Luckily, in most people, restless legs syndrome and periodic limb movement disorder are relatively easily treated. Treatment commonly includes the incorporation of both aerobic and leg stretching exercises. Leg stretching or even yoga exercises can be done prior to bedtime to alleviate symptoms and may be all that is needed in mild cases. Iron replacement therapy is used if patients are iron deficient. Drugs used to treat Parkinson's disease are very effective in treating most cases. These include the drug pramipexole (Mirapex®) and ropinirole (Requip®). Medications, such as valium-type medications, such as clonazepam (Klonopin®) or analgesic medications related to morphine and opium, can be also be used. In some cases, anti-seizure medications may be effective.
Sleepwalking, also referred to as somnambulism, is characterized by
walking or other physical activities during sleep. Sleepwalking is common in
children -- up to 15 percent of children have had this problem -- but can occur
at any age. In children, it can be associated with sleep deprivation or anxiety.
In adults, it is more commonly associated with other medical disorders, medication
use, or anxiety or depressive disorders.
Clinically, the person may simply sit up with their eyes open, appearing to
be awake, or they may engage in a complex task. Episodes can last from seconds
to minutes. Contrary to popular belief, it is safe to wake a sleepwalker, but
they may be confused and disoriented on waking.
There is no specific treatment except to avoid triggers if known, or treat
anxiety or depression. If severe, short-term use of sedatives may be considered.
Otherwise it is best to keep the person safe and out of harm's way. We often
advise families to make sure the windows are closed and that there is no possibility
of sleepwalking leading to danger for the patient.
Sleep Disorders in Medical Illnesses
Many medical illnesses are associated with disturbances of sleep. Patients
with chronic lung disease may experience low oxygen levels at night that disturb
sleep. Patients with asthma may develop wheezing or shortness of breath at night,
usually in the early morning hours. Patients with heart failure may develop
abnormal breathing at night, which disturbs sleep much in the way that sleep
apnea does. Patients with Parkinson's or other neurological diseases may develop
Sleep Disorders in Mental Illnesses
Many people with mental illnesses, notably depression, anxiety, post-traumatic stress syndrome,
and panic attacks, develop profound sleep disturbances. Insomnia is a common
symptom in many people with these problems. Evaluation and treatment by a health care
provider skilled in these disorders, usually in conjunction with evaluation
by a sleep specialist, often brings about great improvement.
