EspañolINSOMNIA
'Insomnia' is a sleep disorder characterized by an inability to sleep and/or inability to remain asleep for a reasonable period. Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time. Both organic and nonorganic insomnia constitute a sleep disorder.[1][2] It can be caused by fear, stress, anxiety, medications, herbs, caffeine, depression, bipolar disorder,
emotional or mental tension, work problems, financial stress, unsatisfactory sex life and sometimes occurs for no apparent reason.[3]
An overactive mind or physical pain may also be causes. Finding the underlying cause of insomnia is usually necessary to cure it. Insomnia can be common after the loss of a loved one, even months or a year after the death, if they are not grieving correctly (pretending they are over it when they are not).
Types of insomnia
Insomnia, Tacuinum sanitatis casanatensis (XIV century)
Three types of insomnia exist: transient, acute, and chronic
#'Transient insomnia' lasts from one night to a few weeks. Most people occasionally suffer from transient insomnia due to such causes as jet lag or short-term anxiety. If this form of insomnia continues to occur from time to time, the insomnia is classified as intermittent.
#'Acute insomnia' is the inability to consistently sleep well for a period of between three weeks to six months.
#'Chronic insomnia' is regarded as the most serious; persists almost nightly for at least a month.
Insomnia versus poor sleep quality
Poor sleep quality can occur as a result of sleep apnea or major depression. Poor sleep quality is caused by the individual not reaching stage 4 or delta sleep which has restorative properties. There are, however, people who are unable to achieve stage 4 sleep due to brain damage who still lead perfectly normal lives.
★ 'Sleep apnea' is a condition that occurs when a sleeping person's breathing is interrupted, thus interrupting the normal sleep cycle. With the obstructive form of the condition, some part of the sleeper's respiratory tract loses muscle tone and partially collapses. People with obstructive sleep apnea often do not remember awakening or having difficulty breathing, but they complain of excessive sleepiness during the day. Central sleep apnea interrupts the normal breathing stimulus of the central nervous system, and the individual must actually wake up to resume breathing. This form of apnea is often related to a cerebral vascular condition, congestive heart failure, and premature aging.
Major depression leads to alterations in the function of the hypothalamus and pituitary causing excessive release of cortisol which can lead to poor sleep quality.
Nocturnal polyuria or excessive nighttime urination can be very disturbing to sleep.[4] Nocturnal polyuria can be nephrogenic (related to kidney disease) or it may be due to prostate enlargement or hormonal influences. Deficiencies in vasopressin, which is either caused by a pituitary problem or by insensitivity of the kidney to the effects of vasopressin, can lead to nocturnal polyuria. Excessive thirst or the use of diuretics can also cause these symptoms.
Treatment for insomnia
In many cases, insomnia is caused by another disease or psychological problem. In this case, medical or psychological help may be useful.
Medications
Many insomniacs rely on sleeping tablets and other sedatives to get rest. All sedative drugs have the potential of causing psychological dependence where the individual cannot psychologically accept that they can sleep without drugs. Certain classes of sedatives such as benzodiazepines and newer non-benzodiazepine drugs can also cause physical dependence which manifests in withdrawal symptoms if the drug is not carefully titrated down. Anti-depressants may have equal effect with less long-term harm than benzodiazepines.[5]
★ The most commonly used class of hypnotics prescribed for insomnia are the benzodiazepines. This includes drugs such as temazepam, diazepam, lorazepam, flurazepam, nitrazepam and midazolam. These medications can be addictive, especially after taking them over long periods of time.
★ Non-benzodiazepine prescription drugs, including the nonbenzodiazepines Ambien and Lunesta, have a cleaner side effect profile than the older benzodiazepines; however, there are controversies over whether these non-benzodiazepine drugs are superior to benzodiazepines. These drugs appear to cause both psychological dependence and physical dependence, and can also cause the same memory and cognitive disturbances as the benzodiazepines along with morning sedation.
★ Melatonin has proved effective for some insomniacs in regulating the sleep/waking cycle, but lacks definitive data regarding efficacy in the treatment of insomnia. Melatonin agonists, including Ramelteon (Rozerem), seem to lack the potential for abuse and dependence. This class of drugs has a relatively mild side effect profile and lower likelihood of causing morning sedation.
★ The antihistamine diphenhydramine is widely used in nonprescription sleep aids, with a 50 mg recommended dose mandated by the FDA. In the United Kingdom, Australia, New Zealand, South Africa, and other countries, a 50 to 100 mg recommended dose is permitted. While it is available over the counter, the effectiveness of these agents may decrease over time and the incidence of next-day sedation is higher than for most of the newer prescription drugs. Dependence does not seem to be an issue with this class of drugs.
★ Some antidepressants such as mirtazapine, trazodone and doxepin have a sedative effect, and are prescribed off label to treat insomnia. The major drawback of these drugs is that they have antihistaminergic, anticholinergic and antiadrenergic properties which can lead to many side effects. Some also alter sleep architecture.
★ Low doses of certain atypical antipsychotics such as quetiapine (Seroquel) are also prescribed for their sedative effect but the danger of neurological and cognitive side effects make these drugs a poor choice to treat insomnia.
Other substances
Some insomniacs use herbs such as valerian, chamomile, lavender, hops, and passion-flower. Valerian has undergone multiple studies and appears to be modestly effective.[6][7][8] Cannabis indica has also been suggested as a very effective treatment for insomnia. [9]
Alcohol may have sedative properties, but the REM sleep suppressing effects of the drug prevent restful, quality sleep. Middle-of-the-night awakenings due to polyuria or other effects from alcohol consumption are common, and hangovers can also lead to morning grogginess.
Insomnia may be a symptom of magnesium deficiency, or lower magnesium levels. A healthy diet containing magnesium, can help to improve sleep in individuals without an adequate intake of magnesium.[10]
Pomegranates are also believed to help insomniacs sleep. Other reports cite the use of an elixir of cider vinegar and honey but the evidence for this is only anecdotal. [11]
Non-medicinal, complimentary and alternative medicine
Recent research has shown that cognitive behavior therapy can be more effective than medication in controlling insomnia [1]. In this therapy, patients are taught improved sleep habits and relieved of counter-productive assumptions about sleep.[12]
Some traditional remedies for insomnia have included drinking warm milk before bedtime, taking a warm bath in the evening; exercising vigorously for half an hour in the afternoon, eating a large lunch and then having only a light evening meal at least three hours before bed, avoiding mentally stimulating activities in the evening hours, and making sure to get up early in the morning and to retire to bed at a reasonable hour.
Using aromatherapy, including jasmine oil, lavender oil, Mahabhringaraj and other relaxing essential oils, may also help induce a state of restfulness. Horlicks is marketed as a sleeping aid.
Many believe that listening to slow paced music will help insomniacs fall asleep. [13]
The more relaxed a person is, the greater the likelihood of getting a good night's sleep. Relaxation techniques such as meditation have been shown to help people sleep. Such techniques can lower stress levels from both the mind and body, which leads to a deeper, more restful sleep.
Traditional Chinese medicine has included treatment for insomnia. A typical approach may utilize acupuncture, dietary and lifestyle analysis, herbology and other techniques, with the goal of resolving the problem at a subtle level.
In the Buddhist tradition, people suffering from insomnia or nightmares may be advised to meditate on "loving-kindness", or ''metta''. This practice of generating a feeling of love and goodwill is claimed to have a soothing and calming effect on the mind and body[14]. This is claimed to stem partly from the creation of relaxing positive thoughts and feelings, and partly from the pacification of negative ones. In the ''Mettā (Mettanisamsa) Sutta''[15], Siddhartha Gautama, the Buddha, tells the gathered monks that easeful sleep is one benefit of this form of meditation.
Statistics for insomnia
According to the U.S. Department of Health and Human Services, approximately 60 million Americans suffer from insomnia each year.[16] Insomnia tends to increase with age and affects about 40 percent of women and 30 percent of men [17]. The average American gets 7 hours of sleep, instead of the 8 to 10 hours recommended by doctors. Children however are recommended more than 8 hours.
