This issue of Sleep Medicine Clinics, guest-edited by Drs. Rachel Markwald and Anne Germain, focuses on Sleep and Performance. This issue is one of four selected each year by series Consulting Editor, Dr. Teofilo Lee-Chiong. Articles include: Work productivity and sleep issues; Sleep apnea and performance; Sleep and athletic performance: the role of untreated sleep issues in sports; Early detection of sleep disorders in safety critical jobs; Insomnia and performance; Exercise for improving insomnia symptoms: implications on performance; Sleep and athletic performance: sleep and visuomotor performance; Brain stimulation for improving sleep and memory; Prevalence of sleep disorders in students and academic performance; PTSD/TBI, Sleep, and Military Operational Performance; New technology for measuring sleep and assessing sleep disorders: implications for public health and safety; and Use of hypnotic medications on learning and memory consolidation.

This issue dives into the study of sleep function, particularly as it relates to memory and cognition. Any clinician who sees patients with sleep disorders, or in particular any sleep medicine specialist, will find this information enlightening and invaluable, as it discusses the current state of understanding of how sleep affects humans’ waking cognitive functions. These review articles describe the research that has taken place, and the lessons that can be taken away from them, so that clinicians can confidently advise their patients on the functional importance of adequate sleep, and recognize cognitive symptoms of inadequate sleep. Articles discuss such topics as animal and human research on sleep and memory, various imaging techniques to describe brain activity during sleep, and the role of dreams.

In this issue of Sleep Medicine Clinics, Guest Editor Erna Sif Arnardottir brings considerable expertise to the topic of Measuring Sleep. Top experts in the field cover key topics such as home sleep recordings, improving machine learning technology, new classification for sleep severity, the role of questionnaires, and more. - Provides in-depth, clinical reviews on Measuring Sleep, providing actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field; Authors synthesize and distill the latest research and practice guidelines to create these timely topic-based reviews. - Contains 10 relevant, practice-oriented topics including getting more sleep from the recording; sleep measurement in women and children; consumer devices; free living sleep measurements; and more.

This issue describes in detail the most current thinking on the way genes affect and determine sleep patterns, behaviors, disorders and needs. Sleep researchers continue to study genetic markers that may someday lead to a personalized approach to treatment of sleep disorders. The genetics of restless legs syndrome, narcolepsy, circadian rhythm disorders, obstructive sleep apnea, parasomnias, and insomnia are discussed. A solid understanding of the role genetics and molecular biology play in sleep will aid clinicians in diagnosing and treating these disorders, as well as advising their patients.

This issue comprises two parts. The first part examines pharmacology of drug classes and effects on the sleep--wake processes. The second part focuses on therapeutics for various sleep disorders. In the first part, basic neuropharmacology of sleep-wake states is discussed. Other articles review hypnotics, allergy and cardiovascular drugs, anti-convulsant drugs, anti-depressant and anti-psychotic drugs, and stimulants. The second part focuses on pharmacology for specific sleep disorders: primary insomnia, co-morbid insomnia, sleep-related breathing disorders, narcolepsy and disorders of daytime sleepiness, movement disroders, parasomnias, and circadian rhythm disorders.

This issue of Sleep Medicine Clinics is edited by Dr. Rami Khayat and focuses on Sleep and the Heart. Article topics include: Mechanisms of SDB and respiratory control instability in heart failure; Rehabilitation of cardiovascular disorders and sleep apnea; Device therapy for SDB in patients with CVD and heart failure; Non-mask based therapies for CSA in patients with heart failure; Movement disorders and non- respiratory sleep disorders in patients with CVD; A practical approach to the identification and management of SDB in heart failure patients.

Excessive Sleepiness, or hypersomnia, is one of the most common sleep complaints. In this issue, Dr. Alon Avidan of UCLA brings together a set of articles that offer a completely updated overview of hypersomnia, from neurophysiology of sleepiness and wakefulness to quality of life issues and public health. The main focus of the issue is the diagnosis and treatment of hypersomnia, including objective and subjective measurement of sleepness, biomarkers of sleepiness, narcolepsy, and hypersomnia in medical, neurological and psyhchiatric comorbidities. Excessive sleepiness among specific patient populations (children, elderly) and periodic hypersomnia are discussed. Pharmacotherapy of hypersomnia is given special attention, as are behavioural treatments.
