BACKGROUND: Although Alzheimer's disease (AD) is a neurodegenerative pathology characterized by accumulation of β-amyloid plaques and neurofibrillary tangles at cerebral level, recent studies highlighted that AD might be the result of many altered physiological processes occurring at whole-organism level. The ability to adapt to stressors by "bending" but not "breaking" can be considered as "resilience". Individuals incline to withstand such pathophysiological challenges, can be considered more resilient than those that do not...

Alzheimer's disease, cerebrovascular disease and aging-related cognitive impairment and dementia (ARCID) increase in prevalence in women with advancing age. The development of Alzheimer's disease, cerebrovascular disease and ARCID may be postponed or prevented by protective measures including the active treatment of vascular risk factors and continuing exercise and healthy lifestyle from early- and mid-life onward. Bilateral oophorectomy before the natural menopause is associated with an increased incidence of ARCID and the increased risk is significantly reduced by estrogen therapy...

Alzheimer's disease (AD) is a progressive neurodegenerative disease that impairs memory and cognitive judgment. It is the leading cause of dementia in late adult life and is associated with a significant social burden and increased morbidity and mortality in the elderly. Because of mixed effectiveness of medications, exercise has been considered as a treatment for pre-clinical AD, late stage AD, and as a prevention strategy. Exercise appears to improve brain blood flow, increase hippocampal volume, and improve neurogenesis...

PURPOSE OF REVIEW: Memory loss can be due to a wide variety of causes. We provide new information about the biology of common genetic and acquired causes of memory loss in older adults. RECENT FINDINGS: New data are available about the genetics of Alzheimer disease (AD), dementia with Lewy bodies (DLB), and frontotemporal dementia. Amyloid PET, FDG-PET, and MRI have improved our understanding of how mild cognitive impairment evolves to AD. Several studies have shown links between concussion and chronic traumatic encephalopathy...

PURPOSES: Sundown syndrome and sleep disturbances cause people with Alzheimer disease (PAD) and caregivers suffering. Studies have indicated that physical exercise could have a positive impact on sundown syndrome, yet no research has ever explored the relationship between walking and sundown syndrome. The aims of this study were to examine the relationship between sundown syndrome and sleep quality, and determine whether the severity of dementia, sleep quality, and weekly duration of walking influenced sundown syndrome, and to assess differences in sundown syndrome and sleep quality in relation to the accompanying walker and weekly duration of walking among people with Alzheimer disease living in the community...

AIM: The objectives of this study were to illuminate how family members of persons with dementia describe their own experiences, before and after placing the relative in a nursing home. Background In the western world and with a growing population of older people, the number of persons with dementia increase. Family members often become carers in their own homes creating stressful and exhausting situation that eventually leads to re-locating the person to a 6 nursing home. This may lead to troubled conscience among family members...

INTRODUCTION: Evidence-based fall prevention (EBFP) programs significantly decrease fall risk, falls, and fall-related injuries in community-dwelling older adults. To date, EBFP programs are only validated for use among people with normal cognition and, therefore, are not evidence-based for adults with intellectual and/or developmental disorders (IDD) such as Alzheimer's disease and related dementias, cerebral vascular accident, or traumatic brain injury. BACKGROUND: Adults with IDD experience not only a higher rate of falls than their community-dwelling, cognitively intact peers but also higher rates and earlier onset of chronic diseases, also known to increase fall risk...

BACKGROUND: The promotion and maintenance of higher physical activity (PA) levels in the older population is an imperative for cognitive and healthy ageing but it is unclear what approaches are best suited to achieve this for the increasing number of older people living in the community. Effective policies should be informed by robust, multi-disciplinary and multi-dimensional evidence, which not only seeks what works, but in 'what context? In addition to evidence on the efficacy and effectiveness of PA for maintaining cognitive health, social contexts such as 'how do we actually get older people to partake in PA?' and 'how do we sustain that activity long-term?' also need highlighting...

Chair based exercise (CBE) can be used to engage older adults unable to take part in standing exercise programmes. Defining and understanding the context of CBE have been acknowledged as a challenge. We explore instructor experiences of delivering mostly seated exercise classes for older people and how this helps us to further understand the concept of CBE. We extracted qualitative data from a cross-sectional survey with 731 exercise instructors. 378 delivered mostly seated classes and 223 of those instructors provided qualitative data...

BACKGROUND: Greater hippocampal volume is observed in healthy older adults after short-term structured exercise. Whether long-term exposure to real-world physical activity (PA) programs has similar effects for sedentary older adults with impaired mobility and comorbid conditions is not known. HYPOTHESIS: A long-term moderate intensity regimen of PA is related to larger volume of the hippocampus in older adults at risk for mobility disability. We further explore whether these associations are modified by factors known to be related to dementia...

Vascular dementia is the progressive change in blood vessels that leads to neuronal injuries in vulnerable areas induced by chronic cerebral hypoperfusion (CCH). CCH induces disruption of blood-brain barrier (BBB), and this BBB disruption can initiate the cognitive impairment and white matter injury. In the present study, we evaluated the effect of treadmill exercise on the cognitive impairment, white matter injury, and BBB disruption induced by CCH. Vascular dementia was induced by permanent bilateral common carotid arteries occlusion (BCCAO) in rats...

Observational and interventional studies indicate a direct link between the patients' physical activity and the extent of behavioral and psychological symptoms of dementia (BPSD). At present, there are no evidence-based recommendations for physical exercise in the acute dementia care settings. Hence, this systematic review investigates the effects of short-term exercise trials on BPSD. Trials with a length up to three months investigating the effects of structured exercise interventions on BPSD in acute dementia care settings were included...

Genetics and lifestyle independently determine dementia risk, but the interaction is unclear. We assessed the interactive relationship of apolipoprotein E (APOE) genotype and physical exercise on dementia risk over a 5-year period in 1,646 older adults from the Canadian Study of Health and Aging who were dementia-free at baseline. Physical exercise moderated the relationship between genotype and dementia (p < 0.01). Specifically, for APOE ɛ4 non-carriers, the odds of developing dementia were higher in non-exercisers than exercisers (OR = 1...

Dementia is a disease characterized by cognitive impairment and physical decline that worsens over time. Exercise is one lifestyle factor that has been identified as a potential means of reducing or delaying progression of the symptoms of dementia, maximizing function and independence. The purpose of this study was to explore physical therapists' (PTs) experiences and reflections on facilitating high-intensity functional exercise with older people living with dementia, in residential care home settings. The study used a qualitative design based on interviews, individually or in small groups, with seven PTs engaged as leaders in the training of older people with dementia...

BACKGROUND: Dementia is a national health priority in Australia. Most people with dementia are over the age of 65 years, have a number of comorbidities and experience a trajectory of functional decline. General practitioners (GPs) have an important role in the diagnosis and management of people with dementia. The Cognitive Decline Partnership Centre's Clinical practice guidelines and principles of care for people with dementia (Guidelines) was recently approved by the National Health and Medical Research Council (NHMRC)...

Early detection and intervention for dysphagia is important in patients with congestive heart failure (CHF). However, previous studies have focused on how many patients with dysphagia develop CHF. Studies focusing on the comorbidity of dysphagia in patients with CHF are rare. Additionally, risk factors for dysphagia in patients with CHF are unclear. Thus, the aim of this study was to clarify risk factors for dysphagia in patients with acute exacerbation of CHF. A total of 105 patients, who were admitted with acute exacerbation of CHF, were enrolled...

BACKGROUND: According to the World Alzheimer Report (Prince, The Global Impact of Dementia: an Analysis of Prevalence, Incidence, Cost and Trends, 2015), 46.8 million people worldwide are nowadays living with dementia. And this number is estimated to approximate 131.5 million by 2050, with an increasing burden on society and families. The lack of medical treatments able to stop or slow down the course of the disease has moved the focus of interest toward the nonpharmacological approach and psychosocial therapies for people with/at risk of dementia, as in the Mild Cognitive Impairment (MCI) condition...
