InsomniaAbout one-third of Americans have symptoms of insomnia but less than 10% of those are identified by their doctors. Insomnia tends to increase with age and affects about 40 percent of women and 30 percent of men. Insomnia includes not only difficulty falling asleep (this is called sleep-onset insomia) but also waking up to early and not being able to fall back asleep (sleep-maintenance insomnia), frequent awakenings, and waking up feeling unrefreshed. Symptoms of insomnia include sleepiness, fatigue, decreased alertness, poor concentration, decreased performance, depression during the day and night, muscle aches and an overly emotional state. Temporary insomnia can be brought on by stress, illness, pain, diet, medications and disruptions to circadian rhythms. When symptoms occur more than a few times a week and affect daily functioning, the person should consult a health care provider. Experts say that chronic insomnia is a greater mortality risk than smoking, high blood pressure and heart disease. Treatment for insomnia can include medication and behavioral strategies. Depending on how severe the case, doctors may prescribe non-benzodiazepine hypnotics, antidepressants and hypnotics. Behavioral strategies are:
How much sleep does a person need? Sleep onset insomnia is when a person can't get to sleep when he or she wants to. In chronic conditions, when the person also has difficulty getting up in the morning, this can be classified as delayed sleep phase syndrome. In this case, the person's clock is just off: when the body wants to sleep is not the same as when the mind wants to sleep. More frequent and pedestrian sleep onset insomnia is just caused by having a lot on your mind or by being nervous. Anxiety-induced insomnia is also called Psychophysiological Insomnia. This is usually short term. In severe situations, this type of insomnia can often be treated with behavioral therapy. The person learns to relax or medidate or systematically clear the mind. Sleep maintenance insomnia results in frequent and prolonged nocturnal awakenings, especially in the second half of the night. Many of the new sleep medications introduced in recent decades address sleep maintenance more than falling asleep. Sleep onset insomnia is more common in young adults while sleep maintenance insomnia is common in the elderly. Delayed sleep phase syndrome usually strikes in adolescence, so it makes sense that young adults are more prone to sleep onset insomnia. Primary InsomniaPrimary insomnia is sleeplessness that cannot be attributed to some other cause. An estimated 10% of the population has primary insomnia. The pathophysiogical mechanisms underlying primary insomnia are usually unknown, and medical practioners address the insomnia directly. Sleep researchers believe that hyperarousal, circadian dysrhythmia, and homeostatic dysregulation underlie chronic insomnia. But as a practical matter for doctors, patients just want a good night’s sleep. The first line of attack for primary insomnia is almost always drug-free. Good sleep hygiene is always recommended, and those suffering from sleepless nights are advised to take another look at their bed practices. Often turning down the air temperature in the room is all it takes to facilitate unbroken sleep. You often see that statement: insomnia is not a condition; it is a symptom. This is to encourage readers (patients, health care providers, etc.) to look at the underlying cause of insomnia, which is often another illness. However, like so much in sleep, this is not so clear. Doctors distinguish between “primary insomnia” and “secondary insomnia”. Secondary insomnia is indeed considered a symptom or a side effect of other phenomena in the body, but often the insomnia itself is considered the main problem, the main thing worth attacking and treating. When the insomnia is considered an illness itself, not an effect of some other etiology, it is called primary insomnia. Chronic insomnia – insomnia that goes on for a month or more – is
often considered primary insomnia. Doctors attack insomnia directly
(rather than an unknown “underlying cause”) to help the patient achieve
a better quality of life. Secondary Insomnia
