Myo-inositol, a second messenger glucose isomer and glial marker, is potentiated by melatonin. In addition to common abnormalities in melatonin regulation, depressive disorders have been associated with reduced myo-inositol in frontal structures. This study examined associations between myo-inositol in the anterior cingulate cortex and the timing of evening melatonin release.

Many adults are insufficiently physically active, have prolonged sedentary behaviour and report poor sleep. These behaviours can be improved by interventions that include education, goal setting, self-monitoring, and feedback strategies. Few interventions have explicitly targeted these behaviours simultaneously or examined the relative efficacy of different self-monitoring methods.

People with bipolar disorder (BD) have a mortality gap of up to 20 years compared to the general population. Physical conditions, such as cardiovascular disease (CVD) and cancer, cause the majority of excess deaths in psychiatric populations and are the leading causes of mortality in people with BD. However, comparatively little attention has been paid to reducing the risk of physical conditions in psychiatric populations.

Sleep disturbance is prevalent in older adults, particularly so in those at a greater risk of dementia. However, so far the clinical, medical and neuropsychological correlates of daytime sleep have not been examined. The aims of this study were to investigate the characteristics and effects of napping using actigraphy in older people, particularly in those 'at risk' of dementia.

Individuals with Prader-Willi syndrome (PWS) have a significant reduction in the number of oxytocin-producing neurons (42%) in the hypothalamic paraventricular nucleus. A number of animal studies and observations of humans show that lesions in this region can produce PWS-like symptoms. Given the evidence for potential oxytocin deficiency, we tested the effects of a course of intranasal oxytocin on PWS symptoms.

Considering the marked changes in sleep and circadian rhythms across the lifespan, age may contribute to the heterogeneity in sleep-wake profiles linked to mood disorders. This study aimed to investigate the contributions of age and depression severity to sleep-wake disturbances. The Hamilton Depression Rating Scale (HDRS) was administered to assess current symptoms severity in 238 persons with a history of a mood disorder between 12 and 90 years of age (y.

While it is evident that Alzheimer's disease is associated with disturbed sleep and circadian rhythms, the extent to which such changes are evident in older people 'at risk' of developing dementia is unknown.
In this study, we aimed to determine whether patients with mild cognitive impairment (MCI) demonstrated significant alterations in the timing of melatonin secretion onset and amount, as well as sleep architecture.
Thirty patients with MCI and 28 age-matched controls underwent psychiatric, medical, and neuropsychological assessment, followed by overnight polysomnography and dim light melatonin onset assessment.

Schizophrenia is a psychiatric disorder that includes symptoms such as hallucinations, disordered thoughts, disorganized or catatonic behaviour, cognitive dysfunction and sleep-wake disturbance. In addition to these symptoms, cardiometabolic dysfunction is common in patients with schizophrenia. While previously it has been thought that cardiometabolic symptoms in patients with schizophrenia were associated with medications used to manage this disorder, more recently it has been demonstrated that these symptoms are present in drug naive and unmedicated patients.

Major depression is one of the leading causes of premature death and disability. Although available drugs are effective, they also have substantial limitations. Recent advances in our understanding of the fundamental links between chronobiology and major mood disorders, as well as the development of new drugs that target the circadian system, have led to a renewed focus on this area.

There is a growing appreciation regarding the relationship between common neurodegenerative diseases, such as Alzheimer's and Parkinson's and sleep-wake disturbances. These clinical features often herald the onset of such conditions and certainly appear to influence disease phenotype and progression. This article reviews some of the pathophysiological processes underlying specific disruptions within the neural circuitry underlying sleep-wake disturbances and explores how clinicopathological relationships commonly manifest.

With the increasing aging population, neurodegenerative disorders will become more common in clinical practice. These disorders involve multiple pathophysiological mechanisms that differentially affect cognition, mood, and physical functions. Possibly due to the involvement of common underlying neurobiological circuits, sleep and/or circadian (sleep-wake) changes are also common in this disease group.

In the 1940s nurses in the United States set out to learn the Kenny method of treating polio patients, which relied on hot packs and muscle strengthening exercises instead of the standard system of prolonged immobilization. Named for Sister Elizabeth Kenny, an Australian nurse who based herself in Minnesota during the 1940s and early 1950s, and viewed with suspicion by many physicians, nurses, and physical therapists, the treatment nonetheless proved effective. It changed the practice of polio nursing and the experiences of patients in the years before vaccine prevention largely eliminated paralytic polio.

Continuous positive airway pressure (CPAP) use is associated with reduced motor vehicle accidents in patients with obstructive sleep apnea (OSA). However, interruption of CPAP therapy is common and is associated with a decline in daytime function.
We hypothesized that the wakefulness promoter, modafinil, would ameliorate this decline.

Primary insomnia is a sleep disorder where the subjective complaint of initiating or maintaining sleep, or the experience of sleep that is non-refreshing, cannot be directly attributed to a comorbid medical or psychiatric disorder. For a diagnosis of primary insomnia, a patient must also report that the nighttime sleep disturbance is impacting upon daytime functioning. Yet, while subjective complaints of impaired wake-time functioning are well documented, consistent objective evidence of these impairments has proved elusive, particularly with regard to cognitive functioning.

During the 1920s and 1930s, disabled polio survivors initiated a campaign which made them active, dissenting subjects in public discourse about disease and disability. Its source was a core of Warm Springs patients who wanted more than a healing refuge. They were well aware of the need to construct a new image of the disabled, and saw the resort's high public profile as a potent weapon in a cultural war to remake popular images of the disabled, whether as pathetic charitable objects or as horrific movie villains.

The demands of sustaining high levels of neurobehavioral performance during space operations necessitate precise scheduling of sleep opportunities in order to best preserve optimal performance. We report here the results of the first split-sleep, dose-response experiment involving a range of sleep/wake scenarios with chronically reduced nocturnal sleep, augmented with a diurnal nap. To characterize performance over all combinations of split sleep in the range studied, we used response surface mapping methodology.

Night eating syndrome (NES) is characterized by evening hyperphagia and frequent awakenings accompanied by food intake. Patients with NES display a delayed circadian pattern of food intake but retain a normal sleep-wake cycle. These characteristics initiated the current study, in which the phase and amplitude of behavioral and neuroendocrine circadian rhythms in patients with NES were evaluated.

Depression in older adults is associated with neuropsychological dysfunction, fronto-subcortical brain changes and sleep disturbance. Research suggests that adequate sleep is critical for many aspects of cognition including processing speed, verbal skills and memory. However, the association between sleep disturbance and neuropsychological functioning in depression has not been well evaluated.

We hypothesized that individuals with untreated obstructive sleep apnea (OSA) would exhibit greater vulnerability to sleep deprivation than healthy controls, due to the additional neurobiological 'load' of chronic sleep fragmentation. After baseline sleep with 8 h time in bed, participants remained awake for 40 h. Psychomotor Vigilance Task (PVT, mean slowest 10% 1/RT), AusEd Driving Simulator task (steering and speed deviation), and subjective sleepiness (Karolinska Sleepiness Scale, KSS) were assessed every 2 h.

This article examines the writings and teachings of eminent American medical historian Charles E. Rosenberg from the perspective of one of his former graduate students. It examines the appeal of the integrative quality of Rosenberg's historical approach; his attention to imperfect and inconsistent ideology; his use of graphic examples to shock and engage; his preference for continuity over change; his rejection of nostalgia and romanticism; the influence of his teacher Erwin Ackerknecht; and Rosenberg's response to American health policy issues.

America's medical schools have long used human cadavers to teach anatomy, but acquiring adequate numbers of bodies for dissection has always been a challenge. Physicians and medical students of the 18th and 19th centuries often resorted to robbing graves, and this history has been extensively examined. Less studied, however, is the history of body acquisition in the 20th century, and this article evaluates the factors that coalesced to transition American society from body theft to body donation.

Race and the politics of polio: Warm Springs, Tuskegee, and the March of Dimes.

Am J Public Health 2007 May 29;97(5):784-95. Epub 2007 Mar 29.
Naomi Rogers
The Tuskegee Institute opened a polio center in 1941, funded by the March of Dimes. The center's founding was the result of a new visibility of Black polio survivors and the growing political embarrassment around the policy of the Georgia Warm Springs polio rehabilitation center, which Franklin Roosevelt had founded in the 1920s before he became president and which had maintained a Whites-only policy of admission. This policy, reflecting the ubiquitous norm of race-segregated health facilities of the era, was also sustained by a persuasive scientific argument about polio itself: that Blacks were not susceptible to the disease.

Application of computer vision to track changes in human facial expressions during long-duration spaceflight may be a useful way to unobtrusively detect the presence of stress during critical operations. To develop such an approach, we applied optical computer recognition (OCR) algorithms for detecting facial changes during performance while people experienced both low- and high-stressor performance demands. Workload and social feedback were used to vary performance stress in 60 healthy adults (29 men, 31 women; mean age 30 yr).

Caffeine is one of the most widely consumed drugs in the world, taken socially and for its alertness- and performance-promoting actions. Extensive reports assert that caffeine increases alertness and cognitive performance levels and, when taken before exercise, demonstrates ergogenic properties. Caffeine ingestion has been associated with increased performance during endurance submaximal, and acute, high-intensity exercise.

Waking neurobehavioural or cognitive functioning is largely dependent on two mechanisms both in synchrony and in opposition to each other: the sleep homeostatic and circadian systems. The influences of these systems are particularly evident during periods of sustained wakefulness or sleep deprivation. Although the effects of these two systems on neurobehavioural functioning during periods of extended wakefulness have been demonstrated experimentally, there does not exist an adequate theory to describe the underlying brain mechanisms responsible for these neurobehavioural deficits.
