A New Technique

Sleep complaints are prevalent among older adults. Sleep quality and quantity changes with advancing age. There are changes in sleep patterns that are normal with ageing but many changes are the sign of disordered sleep. Sleep can be divided into rapid eye movement (REM) sleep and non-rapid eye movement sleep (NREM). Each has unique characteristics that are differentiated by their waveforms on the electroencephalogram (EEG) and by other physiological signals; several physiological age-related changes are thought to produce alterations in circadian rhythms. While there are numerous psychological and social factors contributing to quality and quantity of sleep, specific sleep disorders more prevalent in old age are insomnia, sleep apnea, and rapid eye movement disorder. Non-pharmacological treatment is effective in management of sleep disorders. Cognitive behaviour therapy is most effective to tackle insomnia. Cognitive behavior therapy along with meditation is beneficial for other sleep disorders and a new technique is also emerging: mindfulness.

Sleep Mechanism

Recent research has generated an enormous fund of knowledge about the neurobiology of sleep and wakefulness. Sleeping and waking brain circuits can now be studied by sophisticated neuroimaging techniques that map different areas of the brain during different sleep states and stages. Although the exact biologic functions of sleep are not known, sleep is essential, and sleep deprivation leads to impaired attention and decreased performance. Sleep is also believed to have restorative, conservative, adaptive, thermoregulatory, and consolidative functions. This review discusses the physiology of sleep, including its two independent states, rapid eye movement (REM) and non–rapid eye movement (NREM) sleep, as well as functional neuroanatomy, physiologic changes during sleep, and circadian rhythms. The classification and diagnosis of sleep disorders are discussed generally. The diagnosis and treatment of the following disorders are described: obstructive sleep apnea syndrome, narcolepsy-cataplexy sydrome, idiopathic hypersomnia, restless legs syndrome (RLS) and periodic limb movements in sleep, circadian rhythm sleep disorders, insomnias, nocturnal frontal lobe epilepsy, and parasomnias. Sleep-related movement disorders and the relationship between sleep and psychiatric disorders are also discussed. Tables describe behavioral and physiologic characteristics of states of awareness, the international classification of sleep disorders, common sleep complaints, comorbid insomnia disorders, causes of excessive daytime somnolence, laboratory tests to assess sleep disorders, essential diagnostic criteria for RLS and Willis-Ekbom disease, and drug therapy for insomnia. Figures include polysomnographic recording showing wakefulness in an adult; stage 1, 2, and 3 NREM sleep in an adult; REM sleep in an adult; a patient with sleep apnea syndrome; a patient with Cheyne-Stokes breathing; a patient with RLS; and a patient with dream-enacting behavior; schematic sagittal section of the brainstem of the cat; schematic diagram of the McCarley-Hobson model of REM sleep mechanism; the Lu-Saper “flip-flop” model; the Luppi model to explain REM sleep mechanism; and a wrist actigraph from a man with bipolar disorder. This review contains 14 highly rendered figures, 8 tables, 115 references, and 5 MCQs.

AbstractAge-related differences in dog sleep and the age at which dogs reach adulthood as indexed by sleep electrophysiology are unknown. We assessed, in (1) a Juvenile sample (n = 60) of 2–14-month-old dogs (weight range: 4–68 kg), associations between age, sleep macrostructure, and non-rapid eye movement (NREM) EEG power spectrum, whether weight moderates associations, and (2) an extended sample (n = 91) of 2–30-months-old dogs, when sleep parameters stabilise. In Juvenile dogs, age was positively associated with time in drowsiness between 2 and 8 months, and negatively with time in rapid eye movement (REM) sleep between 2 and 6 months. Age was negatively associated with delta and positively with theta and alpha power activity, between 8 and 14 months. Older dogs exhibited greater sigma and beta power activity. Larger, > 8-month-old dogs had less delta and more alpha and beta activity. In extended sample, descriptive data suggest age-related power spectrum differences do not stabilise by 14 months. Drowsiness, REM, and delta power findings are consistent with prior results. Sleep electrophysiology is a promising index of dog neurodevelopment; some parameters stabilise in adolescence and some later than one year. Determination of the effect of weight and timing of power spectrum stabilisation needs further inquiry. The dog central nervous system is not fully mature by 12 months of age.

Sleep Behavior

Ever since there have been written historical narratives, sleep anomalies have been noted, from medieval paintings of demons terrorizing an individual in their sleep, to biblical revelations in dreams and nightmares, to tales of somnambulism from Shakespeare to Disney. Mysterious parasomnias have been recognized well before they could be classified into the International Classification of Sleep Disorders. With the invention in the 1950s of the electroencephalogram, generations of sleep researchers have been able to classify once mysterious sleep anomalies as either rapid eye movement (REM) or NREM parasomnias. Some parasomnias may be benign and self-limited, such as sleepwalking in a child. Others may lead to injury or can be a sign of other neurological disorders, such as REM sleep behavior disorder. Some can terrify patients and are commonly underreported, such as sleep paralysis, which has been confused by some as modern-day alien abductions. The treatment of parasomnias depends on proper identification based on well-established criteria. Subsequently, integrative approaches to the treatment of these disorders may be applied.

Meaningful Stimuli

Sleep consists of a highly patterned sequence of cyclic activity in various regions of the brain; it is not simply a state of temporary unconsciousness. Although the brain is less responsive than normal during sleep, it is not totally unresponsive. In fact, during sleep the brain responds more readily to meaningful stimuli. Rapid eye movement (REM) sleep can be characterized as a period when the brain is active and the body is paralyzed, whereas in nonrapid eye movement (NREM) sleep, the brain is less active but the body can move. Sleep disorders are grouped into three general categories, based on whether patients have trouble staying awake, trouble sleeping, or abnormal behaviors during sleep.

Rhythm Disorder

The diagnosis of sleep and circadian rhythm disorders provides a detailed framework to correctly diagnose the primary sleep disorders that a psychiatrist will see in daily practice, including common sleep-related movement disorders. This includes the specific sleep history, the role of sleep diaries, validated questionnaires, and how to interpret the scores and the role of both home and inpatient sleep studies (polysomnography). The most recent diagnostic criteria within the International Classification of Sleep Disorder, third edition (ICSD-3) are used for the four major categories of sleep disorder: hypersomnia, insomnia, parasomnia, and circadian rhythm disorder. Common sleep disorders such as obstructive sleep apnoea (OSA), restless legs syndrome (RLS), narcolepsy, and both non-rapid eye movement (NREM) sleep parasomnia and rapid eye movement (REM) parasomnia are described. It is written for qualified specialist doctors.

Objectives: Sleep disturbances are prevalent problems among human immunodeficiency virus (HIV)-infected persons. The recognition of comorbid sleep disorders in patients with HIV is currently hampered by limited knowledge of sleep-related symptoms, sleep architecture, and types of sleep disorders in this population. We aimed to compare the differences in sleep-related symptoms and polysomnography-based sleep disorders between HIV-infected persons and controls. Methods: The study evaluated 170 men with a Pittsburgh sleep quality index scores greater than 5, including 44 HIV-infected men and 126 male controls who were frequency-matched by sex, age (±3.0 years) and BMI (±3.0 kg/m2). For all participants, an overnight sleep study using a Somte V1 monitor was conducted. Differences in sleep-related symptoms and sleep disorders between HIV-infected patients and controls were examined using t-tests or chi-square tests. Results: HIV-infected persons with sleep disturbances more often had psychological disturbances (72.7% vs. 40.5%, p < 0.001) and suspected rapid eye movement behavior disorder (25.0% vs. 4.8%, p < 0.01) than controls. Sleep-disordered breathing was less common in HIV-infected persons than in controls (56.8% vs. 87.3%, p < 0.001). The mean percentage of rapid eye movement sleep was higher among HIV-infected patients than among controls (20.6% vs. 16.6%, p < 0.001). Nocturia was more common in HIV-infected persons than in controls (40.9% vs. 22.2%, p = 0.02). Conclusions: Psychological disturbances and sleep-disordered breathing can be possible explanations of sleep disturbances in HIV-infected persons in whom sleep-disordered breathing is notable. Further studies are warranted to examine the underlying factors of rapid eye movement behavior disorder among HIV-infected persons with sleep disturbances.
