Acutely, almost every individual has experienced a poor night’s sleep, and many short-term remedies for insomnia are tried, including over-the-counter sleep aids and alcohol. Chronic insomnia is the most common sleep disorder, affecting nearly 40 million Americans and accounting for nearly one-third of adults. The annual cost associated with this disorder in the US is estimated at over $15 billion1 and over $100 billion for indirect costs, such as costs of self-medication, health care-related costs due to exacerbations of comorbid conditions, and costs of reduced productivity.2 Degradations of sleep quantity and sleep quality in insomnia have been associated with deleterious long-term effects, including cardiovascular, endocrine, psychological, and immune system complications. Despite these facts, chronic insomnia is not always perceived as a treatable and important medical condition. Symptoms are not always proffered by patients, and diagnoses can be ignored by physicians, partly because insomnia is so common that it is considered somewhat normal, particularly in elderly individuals. These days, recognized treatments for insomnia include pharmacologi-cal therapies and the more recently accepted behavioral therapies, including stimulus control, relaxation, and cognitive and behavioral therapy. Research to evaluate and formulate treatments for insomnia is often beset by the problem that insomnia is usu-ally of multifactorial etiology among individuals. Thus, complex and important ques-tions remain, eg, which types of insomnia can be cured, which therapy is best in each situation and in each patient, and why do so many untreated or suboptimally treated individuals with insomnia exist? There is also a clear need to examine the long-term effects of treatment on diverse cultures, ages, and races and in those with comorbid disorders, using randomized clinical trials of sufficient duration.In the first full year of publication, the Nature and Science of Sleep (NSS) has published a set of articles that begins to examine the advantages and limitations of a number of relatively novel pharmacological and behavioral therapies for insomnia. These papers ought to help clinicians appraise new therapies, better manage insomnia, and identify important gaps in our knowledge and promising future approaches.A number of papers in NSS review new pharmacological strategies for insomnia therapy, including the use of nonbenzodiazepine gamma-aminobutyric acid   receptor agonists such as zolpidem, zaleplon, and eszopiclone (Z-drugs), which potentially have reduced adverse effects with improved safety and tolerance compared with older benzodiazepines;9 the melatonin receptor agonist ramelteon;12 serotonin receptor antagonists;6 and therapies with novel routes of administration, such as oral spray and Nature and Science of Sleep 2011:3 submit your manuscript | www.dovepress.comDovepress Dovepress34Hussain and Sheasublingual tablets.7,11 For instance, administration of zolpidem via a rapid-absorption oral spray or a sublingual tablet can have advantages due to faster onset of action, lower dose requirement, better patient compliance and convenience, and increased bioavailability. Because the Z-drugs are rapid action, they could be used for short-term insomnia, with the precaution that fast-acting drugs could have potentially faster side effects and pose an increased risk for accidental overdose or abuse of the drugs. Moreover, further studies are needed to establish safety, particularly in terms of the carryover of excessive sleepiness into the daytime.11Sleep patterns change with increasing age.   Typically, sleep is lighter, more fragmented, and shorter,9 and the presence of comorbid conditions that interfere with sleep, such as chronic pain, depression, chronic   obstructive   pulmonary disease (COPD), and congestive heart   failure, also lead to a higher prevalence of insomnia in the elderly. An article in NSS high-lights the fact that insomnia is associated with an increased risk of hypertension and cardiovascular disease.13 This inter-relationship between insomnia and   disease can precipitate a vicious circle whereby insomnia can exacerbate disease, which can further exacerbate insomnia. Moreover, interpreta-tion of clinical trials in the elderly becomes challenging due to confounding effects of medications for these comorbid conditions, and decreased clearance of sleep medications. To solve this challenging question, a paper in NSS specifically reviews pharmacotherapy for insomnia in the elderly4 and concludes that eszopiclone is well suited, improving quality of life without the development of drug tolerance and with-out rebound insomnia after discontinuation. Similarly, some promise was suggested for the use of 5-hydroxytryptamine 2A (5-HT2A) antagonists in treating sleep maintenance insomnia.6 Ramelteon was helpful in sleep onset insomnia and circadian rhythm disorder, with no rebound insomnia and reportedly no abuse potential. Ramelteon also did not exac-erbate respiratory disorders such as sleep apnea and COPD, which is a concern for other sedative medications that can depress   ventilation or arousal responses.12 Understanding the molecular and receptor mechanisms involved in promoting sleep in varied disorders could provide future approaches in new drug development. In the long term, more randomized controlled trials are needed to assess both short-term and long-term effects of these medications and their efficacy in comorbid diseases that affect sleep quality or quantity.In search of a better therapeutic approach for insomnia there is an emerging debate about using pharmacotherapy and behavioral therapy to manage insomnia. One of the first studies to formally address this debate using a randomized placebo-controlled trial was published in 1999 and demonstrated that a combined pharmacological and cognitive behavioral therapy for insomnia (CBT-I) was very effective, particularly in terms of duration of effect. Although this was the largest clinical trial in the field at that time, the sample size was relatively small (n = 78), included only elderly people, and the pharmacotherapy included one medication, temazepam. Thus, this result cannot be generalized to a wider population or other drugs.3In this regard, recent papers in NSS have begun to examine CBT-I in varied populations. For instance, a pilot randomized controlled crossover study in breast cancer survivor patients suggested that individualized CBT-I therapy sessions continued to improve sleep quality.10 Furthermore, two studies examined the efficacy of CBT-I in pediatric populations and showed promising results.14,15 Novel multimodal controlled therapies in children aged 5–10 years combined with training sessions with their parents revealed better efficacy and improved compliance.14 This novel age-appropriate treatment program was also very effective in improving sleep efficiency in children aged 11–17 years, possibly reflecting better acceptance in this age group.15CBT-I contains components such as psychotherapy, sleep restriction, paradoxical intention, stimulus control, sleep hygiene, relaxation training, and biofeedback. These techniques can be effective in many patients, but a common problem is accessibility to CBT-I.5 Also, the relative efficacy of individual psychological therapeutic techniques within the components of CBT-I still needs to be evaluated in appropriately controlled studies.Additional individual novel therapies for insomnia are reviewed in NSS, such as Internet-based interventions, bright light treatments, intensive sleep retraining, mindfulness meditation, and acupuncture, and these are assessed for comparative effectiveness with the goal of improved outcomes, reduced costs, and/or improved compliance. Many of these approaches have encouraging findings but still require further research, including randomized placebo-controlled trials, to establish their effectiveness.8Finally, due to the importance of adequate insomnia management, in its first full year, NSS has published numerous original articles that highlight the relative efficacy of specific therapies over others and in specific patient populations. Specifically, NSS has published 12 articles on novel pharmacological and cognitive behavioral therapeutic methods for relieving insomnia in varied populations, including chil-dren, adolescents, adults, and the elderly. Additionally, NSS has published focused reviews on insomnia with comorbid Nature and Science of SleepPublish your work in this journalSubmit your manuscript here: http://www.dovepress.com/nature-and-science-of-sleep-journalNature and Science of Sleep is an international, peer-reviewed, open access journal covering all aspects of sleep science and sleep medicine, including the neurophysiology and functions of sleep, the genetics of sleep, sleep and society, biological rhythms, dreaming, sleep disorders and therapy, and strategies to optimize healthy sleep.
