BACKGROUND: Perceived stress may be a modifiable risk factor for mild cognitive impairment (MCI) and ultimately dementia, but studies on this topic from low- and middle-income countries (LMICs) are lacking. OBJECTIVE: We assessed the association between perceived stress and MCI in six LMICs (China, Ghana, India, Mexico, Russia, and South Africa) using nationally representative data. METHODS: Cross-sectional, community-based data on individuals aged ≥50 years from the World Health Organization's Study on Global Ageing and Adult Health were analyzed...

BACKGROUND: Sarcopenia and frailty are found in up to one-third of the general elderly population. Both are associated with major adverse health outcomes such as nursing home placement, disability, decreased quality of life, and death. Data on the frequency of both syndromes in Parkinson's disease (PD), however, are very limited. OBJECTIVE: We aimed to screen for sarcopenia and frailty in PD patients and to assess potential associations of both geriatric syndromes with demographic and clinical parameters as well as quality of life...

Dysfunction associated with the aging process positions aging as a leading culprit for development of devastating diseases and mounting health-care costs. Many age-associated conditions for which aging increases risk are neurological disorders with no effective treatments, including Alzhei-mer's disease. As the proportion of aged individuals continues to rise in the coming decades, aging-related costs are expected to increase dramatically. Diverse approaches have emerged to meet the clinical need to treat aging and its associated conditions, including those aimed at increasing longevity, slowing the aging process itself, and improving healthspan...

REVIEW
Stefan Kiechl, Johann Willeit
The Bruneck Study is a prospective community-based study enrolling an age- and sex-stratified random sample of 1,000 men and women. It achieved an extraordinary participation rate of 93.4% and a near-complete long-term follow-up exceeding a quarter of a century (1990-2018). High-quality ascertainment of most common human diseases enables reliable evaluation of: disease epidemiology, overlaps between age-related diseases, and risk factors, and discovery of novel biomarkers. Research priorities include atherosclerosis, cardiovascular disease, aging and longevity, neurological diseases, disorders of the bone, and cancer...

BACKGROUND: Atherosclerosis is the leading cause of death worldwide. The disease development is by and large driven by old age and lifestyle factors, such as diet, physical activity, and smoking. In the present study, we have investigated the effect of exercise and diet on the development of atherosclerosis in young and aged mice. OBJECTIVE: This study aimed at comparing multiple age-dependent factors that may influence atherosclerosis in a transgenic mouse model...

The last 2 decades have brought an explosion of research, new products, and general attention to the problem of urinary urgency, and yet patients continue to be plagued by this symptom - especially the elderly. What is it? What does it mean? How can we guide patients successfully through this challenge? This paper presents a review of current thinking about urgency relevant to the practicing clinician, including the epidemiology, pathophysiology, evaluation, and treatment of these patients.

BACKGROUND: Ginseng has been used to improve brain function and increase longevity. However, little is known about the ingredients of ginseng and molecular mechanisms of its anti-brain aging effects. Gintonin is a novel exogenous ginseng-derived lysophosphatidic acid (LPA) receptor ligand; LPA and LPA1 receptors are involved in adult hippocampal neurogenesis. D-galactose (D-gal) is used to induce brain -aging in animal models because long-term treatment with D-gal facilitates hippocampal aging in experimental adult animals by decreasing hippocampal neurogenesis and inducing learning and memory dysfunction...

BACKGROUND: With the increasing global population of older adults, there is a need for environmental interventions that directly affect their physical, psychological, and emotional well-being to help them maintain or regain their independence and autonomy - all of which promote longevity. METHODS: To better understand potential opportunities and challenges associated with interior design and "future homes" that may promote well-being, aging in place, and independent living in older adults, the authors reviewed relevant literature and included their own expert opinions from a multidisciplinary point of view including interior design, wellness, and engineering...

In 2017, there were over 65 million displaced persons at the global level, with approximately 23 million of these people living as refugees around the world. In this same year, the US resettled 53,716 refugees, with the State of Utah receiving 954 of those refugees. Refugees, in general, often face health-related challenges upon resettlement. Since the health of aging refugee men and women is of growing concern, host communities face significant challenges in accommodating the health needs of a diverse refugee population...

BACKGROUND: Specific dual-task (DT) training is effective to improve DT performance in trained tasks in patients with dementia (PwD). However, it remains an open research question whether successfully trained DTs show a transfer effect to untrained DT performances. OBJECTIVE: To examine transfer effects and the sustainability of a specific DT training in PwD. METHODS: One hundred and five patients with mild-to-moderate dementia (Mini-Mental State Examination: 21...

BACKGROUND: Research on terminal decline has widely documented that cognitive performance steeply declines with nearing death. To date, it is unclear whether these changes are normative, based on pathologies associated with (preclinical) dementia, or both. OBJECTIVES: We analyzed heterogeneity in trajectories of terminal cognitive change in Swiss nursing home residents with the objective of examining whether terminal change is normative or whether one or multiple subgroup(s) with relative stability exist...

BACKGROUND: Thyroid hormones have significant effects on the cardiovascular systems. In general, hyperthyroidism is associated with an increased risk of dysrhythmias, while hypothyroidism may cause atherosclerosis. Recent large studies have sought to identify aging-associated changes in thyroid function and their relevance to cardiovascular morbidity and mortality in the elderly. Conflicting results have often been published, likely due to the heterogeneity of the studied populations...

Sangkyu Kim, S Michal Jazwinski
The gut microbiota shows a wide inter-individual variation, but its within-individual variation is relatively stable over time. A functional core microbiome, provided by abundant bacterial taxa, seems to be common to various human hosts regardless of their gender, geographic location, and age. With advancing chronological age, the gut microbiota becomes more diverse and variable. However, when measures of biological age are used with adjustment for chronological age, overall richness decreases, while a certain group of bacteria associated with frailty increases...

The glymphatic system is a glial-dependent waste clearance pathway in the brain, in place of lymphatic vessels, dedicated to drain away soluble waste proteins and metabolic products. Specifically, the glymphatic network serves as a "front end" for waste clearance, and is connected downstream to an authentic lymphatic network, associated with dura covering the brain as well as cranial nerves and large vessels at the skull exits. The anatomical and functional interconnections between these two networks are not completely understood...

BACKGROUND: Fall-related psychological concerns are common among older adults, potentially contributing to functional decline as well as to restriction of activities and social participation. To effectively prevent such negative consequences, it is important to understand how even very low concern about falling could affect physical activity behavior in everyday life. We hypothesized that concern about falling is associated with a reduction in diversity, dynamics, and performance of daily activities, and that these features can be comprehensively quantified in terms of complexity of physical activity patterns...
