Human cognitive aging has been too long neglected and underappreciated for its critical importance to quality of life in old age. The articles in this session present novel approaches to improving cognitive function in normal aging persons with drugs and interventions that are based on findings in epidemiology, studies in aged animals, and in vitro research. In addition, since aging is the primary risk factor for Alzheimer's disease, these studies also have implications as interventions for prevention and treatment. As a field of research, new knowledge regarding the causes and mechanisms of cognitive aging are ripe for translation into human studies, with the application of this knowledge leading the development of interventions and therapeutics for the prevention of cognitive decline in old age and Alzheimer's disease. © 2012 The Gerontological Society of America.

Considerable knowledge has been gained from epidemiologic studies and randomized clinical trials regarding risk factors for dementia, including Alzheimer disease (AD) and vascular dementia (VaD). Most identified risk factors for dementia are similar to vascular disease risk factors for heart disease and stroke. In 2010, the National Institutes of Health Conference concluded that there are no validated modifiable factors to reduce the incidence of AD or to change its course. This research perspective specifically concerning AD disregards the fact that in community-dwelling elderly, the most common forms of dementia involve the cerebral macrovasculature and microvasculature, manifesting as VaD and mixed dementia (the combination of VaD and AD) in autopsy-confirmed cases. Thus, prevention of dementia in clinical practice should be considered from this broader and more relevant view and not just a research perspective on "pure" AD. Practicing clinicians can reasonably state to patients that, although more definitive research is clearly needed, the management and treatment of vascular disease risk factors are likely beneficial not only to prevent heart disease and stroke, but also common forms of dementia in the community.© 2012 by Lippincott Williams & Wilkins.

Epidemiological projections of the prevalence of Alzheimer's disease (AD) and related dementias, the rapidly expanding population over the age of 65, and the enormous societal consequence on health, economics, and community foretell of a looming global public health crisis. Currently available treatments for AD are symptomatic, with modest effect sizes and limited impact on longer term disease outcomes. There have been no newly approved pharmaceutical treatments in the last decade, despite enormous efforts to develop disease-modifying treatments directed at Alzheimer's-associated pathology. An unprecedented collaborative effort of government, regulators, industry, academia, and the community at-large is needed to address this crisis and to develop an actionable plan for rapid progress toward successfully developing effective treatments. Here, we map out a course of action in four key priority areas, including (1) addressing the fundamental mechanisms of disease, with the goal of developing a core set of research tools, a framework for data sharing, and creation of accessible validated and replicated disease models; (2) developing translational research that emphasizes rapid progress in disease model development and better translation from preclinical to clinical stages, deploying leading technologies to more accurately develop predictive models; (3) preventing AD through the development of robust methods and resources to advance trials and creating fundamental resources such as continuous adaptive trials, registries, data repositories, and instrument development; and (4) innovating public/private partnerships and global collaborations, with mechanisms to incentivize collaborations and investments, develop larger precompetitive spaces, and more rapid data sharing. © 2014 New York Academy of Sciences.

While Alzheimer's disease researchers continue to debate the underlying cause(s) of the disease, most agree that a diverse, multi-target approach to treatment will be necessary. To this end, the Alzheimer's Drug Discovery Foundation (ADDF) recently hosted the 11th International Conference on Alzheimer's Drug Discovery to highlight the array of exciting efforts from the ADDF's funded investigators. © 2010 BioMed Central Ltd.

Background: Individuals with Alzheimer's disease and related disorders (ADRD) have more frequent hospitalizations than individuals without ADRD, and some of these admissions may be preventable with proactive outpatient care. Methods: This study was a cross-sectional analysis of Medicare claims data from 195,024 fee-for-service ADRD beneficiaries aged ≥65 years and an equal number of matched non-ADRD controls drawn from the 5% random sample of Medicare beneficiaries in 2007-2008. We analyzed the proportion of patients with potentially avoidable hospitalizations (PAHs, as defined by the Medicare Ambulatory Care Indicators for the Elderly) and used logistic regression to examine patient characteristics associated with PAHs. We used paired t tests to compare Medicare expenditures by ADRD status, stratified by whether there were PAHs related to a particular condition. Results: Compared with matched non-ADRD subjects, Medicare beneficiaries with ADRD were significantly more likely to have PAHs for diabetes short-term complications (OR = 1.43; 95% CI 1.31-1.57), diabetes long-term complications (OR = 1.08; 95% CI = 1.02-1.14), and hypertension (OR = 1.22; 95% CI 1.08-1.38), but less likely to have PAHs for chronic obstructive pulmonary disease (COPD)/asthma (OR = 0.85; 95% CI 0.82-0.87) and heart failure (OR = 0.89; 95% CI 0.86-0.92). Risks of PAHs increased significantly with comorbidity burden. Among beneficiaries with a PAH, total Medicare expenditures were significantly higher for those subjects who also had ADRD. Conclusion: Medicare beneficiaries with ADRD were at a higher risk of PAHs for certain uncontrolled comorbidities and incurred higher Medicare expenditures compared with matched controls without dementia. ADRD appears to make the management of some comorbidities more difficult and expensive. Ideally, ADRD programs should involve care management targeting high-risk patients with multiple chronic conditions. © 2013 The Alzheimer's Association. All rights reserved. Source
