Chapter Three - I can't drink what I used to: The interaction between ethanol and the aging brain

Publication date: 2019Source: International Review of Neurobiology, Volume 148Author(s): Douglas B. Matthews, Amelia Schneider, Abigail Kastner, Samantha Scaletty, Rachel SzenayAbstractThe population of most countries is increasing and the United Nations predicts that by the year 2050 those over the age of 60 years old will increase from 900 million individuals to approximately 2.1 billion individuals (United Nations, 2015). The increase in the number of older individuals will place a strain on many national health care systems making it important to investigate behaviors in the aged that may negatively impact general health in this demographic. Recent work has shown that older adults consume alcohol, often at levels that exceed the legal limit of intoxication. Unfortunately, consumption of high levels of ethanol in the older population is associated with many health consequences and may negatively impact the brain. Given ethical constraints found in many biomedical studies, animal models are needed to investigate the possible negative impact of high ethanol use in aged populations. However, few studies have investigated the effect of ethanol exposure in aged animals compared to ethanol exposure in younger animals and consequently the impact of ethanol in the aged population is not well understood.The current review summarizes initial work establishing the impact of ethanol in aged animals. The reviewed research studies support the working hypothesis that ethanol exposure pro...

Resumo Este artigo tem por base uma investiga ção realizada entre novembro de 2013 e janeiro de 2017, na Universidade do Minho (Portugal), sobre os docentes da Universidade Óscar Ribas (UOR) (Angola). Foi alicerçado num referencial teórico, a Psicodinâmica do Trabalho de Christophe Dejours, e teve como objetivos analisar os sintomas biops icossociais e os sentimentos de prazer e/ou de sofrimento relacionados com o trabalho docente. Foi utilizada a metodologia quantitativa, que teve por base a aplicação de um questionário e duas escalas a 56 docentes da UOR. Veri...

ConclusionsFurther research exploring concurrent changes in all movement behaviours (PA, SB and sleep) and associated factors is warranted to inform future behavioural interventions and policies for promoting an optimal 24-h movement behaviour pattern during this critical developmental period.

ConclusionsDifferent patterns of sleep disturbances are observed in HD patients: insomnia, difficulties in falling asleep, frequent nocturnal awakenings, and excessive daytime sleepiness are the most common sleep problems reported by patients with HD. In several HD studies, specific changes in sleep architecture and in circadian melatonin secretion were identified in laboratory testing.Sleep disorders in HD have diverse and complex determinants, the most significant of which includes damage to brain areas that are responsible for the proper sleep pattern and circadian rhythm regulation. Sleep and circadian rhythm disorders...

This study indicated that switch from H2 blockers to PPIs reduced delirium and, thus, providing an appropriate strategy to combat drug-induced delirium using antiulcer drugs (Fujii et al., 2012). The ventrolateral preoptic nucleus is a sleep-promoting nucleus located in the basal forebrain. A commonly used intravenous anesthetic, propofol, had been reported to induce sleep and augment the firing rate of neurons in ventrolateral GABAergic preoptic nucleus, but the underlining mechanism is yet to be clearly determined. Interestingly, the propofol-induced inhibition of inhibitory postsynaptic currents on noradrenalin-inhibite...

Discussion Headache is pain in the scalp, forehead, orbits and temple. Facial and neck pain are usually excluded from this definition. It is a common problem with more than 6 million pediatric patients having migraine. Headaches can also have co-morbidities and more than 1 primary headache type can co-exist. The costs are high both economically and in the quality of life for the patients and families. A review of common headache types and indications for neuroimaging can be found here. Treatment is necessarily multi-pronged. Patients should understand their diagnosis so they can understand what reasonably can be expected...

Conclusions:Intake of herbal supplements has increased over the past decade warranting an extensive medication history as part of a full neurological evaluation.

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disease with motor, psychiatric, and cognitive manifestations that occurs in carriers of the fragile X mental retardation 1 (FMR1) gene premutations. This was a retrospective chart review of 196 individuals (127 men and 69 women) with FXTAS. Forty-six (23%) participants were cognitively impaired, of whom 19 (10%) had dementia. Risk factors for dementia were examined (CGG repeat size; alcohol, benzodiazepine, and opioid use; diabetes; hyperlipidemia; hypertension; hypothyroidism; obesity; sleep apnea; surgeries with general anesthesia; dep...
