BACKGROUND: Sleep disturbances, including reduced nocturnal sleep time, sleep fragmentation, nocturnal wandering, and daytime sleepiness are common clinical problems in dementia, and are associated with significant caregiver distress, increased healthcare costs, and institutionalisation. Drug treatment is often sought to alleviate these problems, but there is significant uncertainty about the efficacy and adverse effects of the various hypnotic drugs in this vulnerable population. OBJECTIVES: To assess the effects, including common adverse effects, of any drug treatment versus placebo for sleep disorders in people with dementia, through identification and analysis of all relevant randomised controlled trials (RCTs)...

Sundowning syndrome (SDS) in patients with Alzheimer's disease (AD) is characterized by the intensification of behavioral disorders at sunset. Despite SDS etiology being unclear, a strong relationship between high cortisol levels and SDS has been reported. Aerobic exercise (AE) and cognitive training (CT) can reduce cortisol levels. However, whether SDS would benefit from AE and CT is still unknown. Therefore, the aim of this study was to investigate whether AE and CT treatments are effective in reducing SDS via downregulation of cortisol levels...

The clinical phenomenon of early evening disruptive behavior also called "Sundowning" in elderly patients has been largely reported in the medical literature without a consistent diagnosis and criteria to define this phenomenon. The current understandings of sundowning are incomplete and current treatment strategies have relied heavily on use of antipsychotic medications, despite side effects and limited evidence to justify their use. A comprehensive understanding of the biogenesis of this phenomenon and mechanistic changes from oxidative pathways may provide novel information on completing the sundowning puzzle...

Dementia is one of the big medical challenges of our time with Alzheimer's, Huntington's and Parkinson's disease among its most common forms. In year 2000, 4.5 million people were diagnosed with Alzheimer's disease in the United States. In the case of Alzheimer's disease one of many contributing factors is a metabolic imbalance that leads to elevated oxidative stress levels. Consequences of this imbalance can be symptoms like apraxia, agnosia or sundowning. The use of field-effect transistors is a novel approach to study the effects of external stimuli on cells in vitro to provide researchers with a new tool for high resolution and high throughput studies to better understand cellular interaction and the effects of pharmacological compounds...

Insidious changes in behaviour herald the onset of progressive neurodegenerative disorders such as Huntington's disease (HD), sometimes years before overt symptoms are seen. Sleep and circadian disturbances are particularly disruptive symptoms in patients with neurological disorders, but they are difficult to measure in humans. Here we studied circadian behaviour in transgenic HD sheep expressing the full-length human huntingtin protein with an expanded CAG repeat mutation in the juvenile range. Young HD sheep with no other symptoms exhibited circadian behavioural abnormalities that worsened with age...

Alzheimer's disease (AD), an age-related neurodegenerative disorder with progressive cognition deficit, is characterized by extracellular senile plaques (SP) of aggregated β-amyloid (Aβ) and intracellular neurofibrillary tangles, mainly containing the hyperphosphorylated microtubule-associated protein tau. Multiple factors contribute to the etiology of AD in terms of initiation and progression. Melatonin is an endogenously produced hormone in the brain and decreases during aging and in patients with AD. Data from clinical trials indicate that melatonin supplementation improves sleep, ameliorates sundowning and slows down the progression of cognitive impairment in AD patients...

The pineal hormone melatonin plays a major role in circadian sleep-wake rhythm in many mammals, including humans. Patients with acute confusional state or delirium, especially those with underlying cognitive impairment, frequently suffer from sleep disturbances and disturbed circadian rhythm. In this review, an overview is given of delirium and delirium symptoms that correspond with symptoms in dementia, such as sundowning, followed by a presentation of the circadian rhythm disorders in delirium in relation to melatonin deficiency...

The term "sundowning" describes a clinical phenomenon characterized by late afternoon exacerbation of behavioural symptoms in dementia. Beyond this clinical definition, the debate around this concept is not properly solved, because many authors define it in different ways, mentioning various hypothetical etiological explanations. It represents a concrete problem, which is difficult to manage for physicians and caregivers, and is probably linked to various biological, psychological and social aspects. As recently reported, the sundowning phenomenon is a predictor of faster cognitive decline in Alzheimer's disease, and as such can represent a possible marker of frailty in this illness...

BACKGROUND: In 2010, malaria caused approximately 216 million infections in people and 655,000 deaths. In the United States, imported malaria cases occur every year, primarily in returning travelers and immigrants from endemic countries. In 2010, five Plasmodium falciparum malaria cases occurred among crew members of one US commercial airline company (Airline A). This investigation aimed to assess the malaria prevention knowledge, attitudes, and practices (KAP) of Airline A crew members to provide information for potential interventions...

The label sundown syndrome continues to be frequently used in long-term and acute care settings without consistent meaning. This study adds to the understanding of this label by synthesizing findings from research published since 1987 linked to sundown syndrome. The purpose of this systematic review is to describe, synthesize, and critique the theoretical definitions, operational definitions and measurement methods, prevalence, antecedent and precipitating factors and consequences, and effectiveness of interventions for sundown syndrome found in the published literature...

Secondhand smoke levels were assessed among a convenience sample of 15 public venues in Amman, Jordan, during Ramadan. PM2.5 measurements were taken inside each venue pre- and post-'iftar', when daily smoking abstinence can be broken at sundown. Cigarette smoking was observed in all venues post-iftar, and the median PM(2.5) level among the 15 venues (285 µg/m(3)) was significantly higher than the pre-iftar level (11 µg/m(3); P < 0.001). Post-iftar PM(2.5) levels exceeded the World Health Organization standard for particulate pollution by 5-20-fold...

South American subterranean rodents (Ctenomys aff. knighti), commonly known as tuco-tucos, display nocturnal, wheel-running behavior under light-dark (LD) conditions, and free-running periods >24 h in constant darkness (DD). However, several reports in the field suggested that a substantial amount of activity occurs during daylight hours, leading us to question whether circadian entrainment in the laboratory accurately reflects behavior in natural conditions. We compared circadian patterns of locomotor activity in DD of animals previously entrained to full laboratory LD cycles (LD12:12) with those of animals that were trapped directly from the field...

Tracy A Bedrosian, Randy J Nelson
Both normal aging and dementia are associated with altered circadian regulation of physiology and behavior. Elderly individuals and dementia patients commonly experience disrupted sleep-wake cycles, which may lead to psychomotor agitation, confusion, and wandering. These behaviors are disruptive to both patients and caregivers. Sundowning syndrome, which encompasses many of these behaviors, is characterized by a temporal pattern in the severity of symptoms, usually expressed as worse during the late afternoon or evening...

The term 'Taiji' first appear in Zhouyi·Xici, saying that 'yi has Taiji which includes yin and yang'. Chinese ancestors formed the 'year' conception by observing sunrise, sundown and seasonal successions for a long period. 'yi has Taiji which includes yin and yang' was the resultant recording of their sun-movement observations. People compared the heaven and earth to a circle and they divided the circle into four areas to record meteorological changes of the four seasons. A line was drawn from the spring equinox to the autumn equinox and the heaven and earth positioning diagram was created with the upper half as the heaven and the bottom half as the earth...
