Most parents picture a crying baby when they think about kids and sleep problems.
Many older kids and teens have problems sleeping too, including trouble going to sleep and waking up frequently in the middle of the night. Unfortunately, not getting a good night's sleep can affect your child's mood and behavior during the day, leading to school and discipline problems. Like adults, children with insomnia either have trouble going to sleep, staying asleep, or are simply not well rested after what should be a normal amount of time sleeping.
One common reason that many children don't get enough sleep is that they go to bed too late. This is often because parents have unrealistic expectations for how much sleep their kids need or because their kids are over-scheduled, with too many activities and too much homework.
Or your child may simply be up late texting, talking on the phone, playing video games, or watching TV. Remember that children between the ages of 6 and 13 need about 9 to 11 hours of sleep each night, and teens need about 8 to 10 hours. If you set a realistic bedtime and your child is still not getting a good night's sleep, the common causes of insomnia can include:.
Although parents often want to turn to a prescription to treat their child's insomnia, it is much more important to look for any underlying medical or psychological problems that may need to be treated first. For example, if your child has obstructive sleep apnea and snores loudly at night and frequently stops breathing, then they might need to have their tonsils and adenoids removed.
Or if your child has a frequent nighttime cough because their asthma is poorly controlled, they may need stronger preventive asthma medication. If your child has sleep apnea, asthma, or is depressed, a sleeping pill is not the answer—especially since no sleeping pills have been approved for use by children. Medications which are sometimes used when necessary and appropriate include:. Unless another diagnosis is the cause of your child's insomnia, a prescription is usually not the answer.
Non-drug treatments for primary insomnia, or childhood insomnia that is not caused by another medical condition, can include:. Seeing a counselor or child psychologist, how to change my name in ssc certificate addition to your pediatrician, can also be helpful for most children with insomnia.
If your child's insomnia worsened when they started an ADHD medicine or had an increase in dosage, then the medicine may what part of the brain causes insomnia to blame. Surprisingly, a small dose of a short-acting stimulant in the afternoon or evening actually helps them sleep.

Sleep disorders: An overview
Anorexia nervosa, often referred to simply as anorexia, is an eating disorder, characterized by low weight, food restriction, fear of gaining weight and a strong desire to be thin. Many people with anorexia see themselves as overweight even though they are, in fact, underweight. They often deny that they have a problem with low weight. They weigh themselves frequently, eat small amounts and. Jan 31, · What Causes Depression: Brain Chemistry. You might have heard that depression stems from a “chemical imbalance,” and that’s partly true. In people with depression, the levels of certain brain chemicals are thought to be out of balance, particularly these neurotransmitters: serotonin (which regulates mood, emotion, and sleep). Aug 08, · Primary insomnia may be related to changes in levels of certain brain chemicals, but research is ongoing. Secondary insomnia is caused by other conditions or situations.
Insomnia , also known as sleeplessness , is a sleep disorder in which people have trouble sleeping. Insomnia can occur independently or as a result of another problem. Sleep hygiene and lifestyle changes are typically the first treatment for insomnia. Symptoms of insomnia: . Sleep onset insomnia is difficulty falling asleep at the beginning of the night, often a symptom of anxiety disorders.
Delayed sleep phase disorder can be misdiagnosed as insomnia, as sleep onset is delayed to much later than normal while awakening spills over into daylight hours. It is common for patients who have difficulty falling asleep to also have nocturnal awakenings with difficulty returning to sleep.
Two-thirds of these patients wake up in the middle of the night, with more than half having trouble falling back to sleep after a middle-of-the-night awakening. Early morning awakening is an awakening occurring earlier more than 30 minutes than desired with an inability to go back to sleep, and before total sleep time reaches 6.
Early morning awakening is often a characteristic of depression. Some of these symptoms include tension , compulsive worrying about the future, feeling overstimulated, and overanalyzing past events.
Poor sleep quality can occur as a result of, for example, restless legs , sleep apnea or major depression. Poor sleep quality is defined as the individual not reaching stage 3 or delta sleep which has restorative properties. Major depression leads to alterations in the function of the hypothalamic-pituitary-adrenal axis , causing excessive release of cortisol which can lead to poor sleep quality.
Nocturnal polyuria , excessive nighttime urination, can be very disturbing to sleep. Some cases of insomnia are not really insomnia in the traditional sense, because people experiencing sleep state misperception often sleep for a normal amount of time. Sleep studies using polysomnography have suggested that people who have sleep disruption have elevated nighttime levels of circulating cortisol and adrenocorticotropic hormone.
They also have an elevated metabolic rate, which does not occur in people who do not have insomnia but whose sleep is intentionally disrupted during a sleep study. Studies of brain metabolism using positron emission tomography PET scans indicate that people with insomnia have higher metabolic rates by night and by day. The question remains whether these changes are the causes or consequences of long-term insomnia.
This study showed that the genetic architecture of insomnia strongly overlaps with psychiatric disorders and metabolic traits. It has been hypothesised that the epigenetics might also influence insomnia through a controlling process of both sleep regulation and brain-stress response having an impact as well on the brain plasticity. Alcohol is often used as a form of self-treatment of insomnia to induce sleep. However, alcohol use to induce sleep can be a cause of insomnia.
Frequent moving between sleep stages occurs, with awakenings due to headaches, the need to urinate , dehydration , and excessive sweating. Glutamine rebound also plays a role as when someone is drinking; alcohol inhibits glutamine, one of the body's natural stimulants. When the person stops drinking, the body tries to make up for lost time by producing more glutamine than it needs. During withdrawal REM sleep is typically exaggerated as part of a rebound effect. Like alcohol, benzodiazepines , such as alprazolam , clonazepam , lorazepam , and diazepam , are commonly used to treat insomnia in the short-term both prescribed and self-medicated , but worsen sleep in the long-term.
While benzodiazepines can put people to sleep i. Opioid medications such as hydrocodone , oxycodone , and morphine are used for insomnia that is associated with pain due to their analgesic properties and hypnotic effects. Opioids can fragment sleep and decrease REM and stage 2 sleep. By producing analgesia and sedation , opioids may be appropriate in carefully selected patients with pain-associated insomnia.
Insomnia affects people of all age groups but people in the following groups have a higher chance of acquiring insomnia. Two main models exists as to the mechanism of insomnia, 1 cognitive and 2 physiological.
The cognitive model suggests rumination and hyperarousal contribute to preventing a person from falling asleep and might lead to an episode of insomnia. The physiological model is based upon three major findings in people with insomnia; firstly, increased urinary cortisol and catecholamines have been found suggesting increased activity of the HPA axis and arousal; second increased global cerebral glucose utilization during wakefulness and NREM sleep in people with insomnia; and lastly increased full body metabolism and heart rate in those with insomnia.
All these findings taken together suggest a dysregulation of the arousal system, cognitive system, and HPA axis all contributing to insomnia. Altered levels of the inhibitory neurotransmitter GABA have been found, but the results have been inconsistent, and the implications of altered levels of such a ubiquitous neurotransmitter are unknown.
Studies on whether insomnia is driven by circadian control over sleep or a wake dependent process have shown inconsistent results, but some literature suggests a dysregulation of the circadian rhythm based on core temperature. Around half of post-menopausal women experience sleep disturbances, and generally sleep disturbance is about twice as common in women as men; this appears to be due in part, but not completely, to changes in hormone levels, especially in and post-menopause.
Changes in sex hormones in both men and women as they age may account in part for increased prevalence of sleep disorders in older people. In medicine, insomnia is widely measured using the Athens insomnia scale. A qualified sleep specialist should be consulted for the diagnosis of any sleep disorder so the appropriate measures can be taken. Past medical history and a physical examination need to be done to eliminate other conditions that could be the cause of insomnia.
After all other conditions are ruled out a comprehensive sleep history should be taken. The sleep history should include sleep habits, medications prescription and non-prescription , alcohol consumption, nicotine and caffeine intake, co-morbid illnesses, and sleep environment.
The diary should include time to bed, total sleep time, time to sleep onset, number of awakenings, use of medications, time of awakening, and subjective feelings in the morning. Workers who complain of insomnia should not routinely have polysomnography to screen for sleep disorders.
Some patients may need to do an overnight sleep study to determine if insomnia is present. Such a study will commonly involve assessment tools including a polysomnogram and the multiple sleep latency test.
Specialists in sleep medicine are qualified to diagnose disorders within the, according to the ICSD , 81 major sleep disorder diagnostic categories. In many cases, insomnia is co-morbid with another disease, side-effects from medications, or a psychological problem.
Approximately half of all diagnosed insomnia is related to psychiatric disorders. Determination of causation is not necessary for a diagnosis. The DSM-5 criteria for insomnia include the following: . Predominant complaint of dissatisfaction with sleep quantity or quality, associated with one or more of the following symptoms:. Prevention and treatment of insomnia may require a combination of cognitive behavioral therapy ,  medications,  and lifestyle changes.
Among lifestyle practices, going to sleep and waking up at the same time each day can create a steady pattern which may help to prevent insomnia. It is recommended to rule out medical and psychological causes before deciding on the treatment for insomnia.
Medications have been used mainly to reduce symptoms in insomnia of short duration; their role in the management of chronic insomnia remains unclear. Non-medication based strategies have comparable efficacy to hypnotic medication for insomnia and they may have longer lasting effects. Hypnotic medication is only recommended for short-term use because dependence with rebound withdrawal effects upon discontinuation or tolerance can develop. Non medication based strategies provide long lasting improvements to insomnia and are recommended as a first line and long-term strategy of management.
Behavioral sleep medicine BSM tries to address insomnia with non-pharmacological treatments. The BSM strategies used to address chronic insomnia include attention to sleep hygiene , stimulus control , behavioral interventions, sleep-restriction therapy, paradoxical intention , patient education, and relaxation therapy. Behavioral therapy may include, learning healthy sleep habits to promote sleep relaxation, undergoing light therapy to help with worry-reduction strategies and regulating the circadian clock.
Music may improve insomnia in adults see music and sleep. Stimulus control therapy is a treatment for patients who have conditioned themselves to associate the bed, or sleep in general, with a negative response.
As stimulus control therapy involves taking steps to control the sleep environment, it is sometimes referred interchangeably with the concept of sleep hygiene. A component of stimulus control therapy is sleep restriction, a technique that aims to match the time spent in bed with actual time spent asleep. This technique involves maintaining a strict sleep-wake schedule, sleeping only at certain times of the day and for specific amounts of time to induce mild sleep deprivation.
Complete treatment usually lasts up to 3 weeks and involves making oneself sleep for only a minimum amount of time that they are actually capable of on average, and then, if capable i. Bright light therapy may be effective for insomnia. Paradoxical intention is a cognitive reframing technique where the insomniac, instead of attempting to fall asleep at night, makes every effort to stay awake i. One theory that may explain the effectiveness of this method is that by not voluntarily making oneself go to sleep, it relieves the performance anxiety that arises from the need or requirement to fall asleep, which is meant to be a passive act.
This technique has been shown to reduce sleep effort and performance anxiety and also lower subjective assessment of sleep-onset latency and overestimation of the sleep deficit a quality found in many insomniacs.
Sleep hygiene is a common term for all of the behaviors which relate to the promotion of good sleep. They include habits which provide a good foundation for sleep and help to prevent insomnia. However, sleep hygiene alone may not be adequate to address chronic insomnia.
The creation of a positive sleep environment may also be helpful in reducing the symptoms of insomnia. In order to create a positive sleep environment one should remove objects that can cause worry or distressful thoughts from view.
There is some evidence that cognitive behavioral therapy for insomnia CBT-I is superior in the long-term to benzodiazepines and the nonbenzodiazepines in the treatment and management of insomnia.
Common misconceptions and expectations that can be modified include. Numerous studies have reported positive outcomes of combining cognitive behavioral therapy for insomnia treatment with treatments such as stimulus control and the relaxation therapies.
Hypnotic medications are equally effective in the short-term treatment of insomnia, but their effects wear off over time due to tolerance. The effects of CBT-I have sustained and lasting effects on treating insomnia long after therapy has been discontinued. The long lasting benefits of a course of CBT-I shows superiority over pharmacological hypnotic drugs.
Even in the short term when compared to short-term hypnotic medication such as zolpidem, CBT-I still shows significant superiority. Thus CBT-I is recommended as a first line treatment for insomnia. CBT is the well-accepted form of therapy for insomnia since it has no known adverse effects, whereas taking medications to alleviate insomnia symptoms have been shown to have adverse side effects. Metacognition is a recent trend in approach to behaviour therapy of insomnia.
Despite the therapeutic effectiveness and proven success of CBT, treatment availability is significantly limited by a lack of trained clinicians, poor geographical distribution of knowledgeable professionals, and expense. The Internet has already become a critical source of health-care and medical information. These online programs are typically behaviorally-based treatments that have been operationalized and transformed for delivery via the Internet. They are usually highly structured; automated or human supported; based on effective face-to-face treatment; personalized to the user; interactive; enhanced by graphics, animations, audio, and possibly video; and tailored to provide follow-up and feedback.
There is good evidence for the use of computer based CBT for insomnia. Many people with insomnia use sleeping tablets and other sedatives. The percentage of adults using a prescription sleep aid increases with age.
