Lithium Treatment Of Appswdi/Nos2−/− Mice Leads To Reduced Hyperphosphorylated Tau, Increased Amyloid Deposition And Altered Inflammatory Phenotype, Tiffany L. Sudduth, Joan G. Wilson, Angela Everhart, Carol A. Colton, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

Lithium is an anti-psychotic that has been shown to prevent the hyperphosphorylation of tau protein through the inhibition of glycogen-synthase kinase 3-beta (GSK3β). We recently developed a mouse model that progresses from amyloid pathology to tau pathology and neurodegeneration due to the genetic deletion of NOS2 in an APP transgenic mouse; the APPSwDI/NOS2-/- mouse. Because this mouse develops tau pathology, amyloid pathology and neuronal loss we were interested in the effect anti-tau therapy would have on amyloid pathology, learning and memory. We administered lithium in the diets of APPSwDI/NOS2-/- mice for a period of eight months, followed by water maze …

Elucidating The Mechanisms Underlying Alzheimer's Disease-Associated Genetic Polymorphisms, Steven Estus

Sanders-Brown Center on Aging Presentations

Recent genome-wide association studies (GWAS) have yielded a bounty of single nucleotide polymorphisms (SNP)s related to Alzheimer's disease (AD) or conditions associated with AD. Here, we will present several vignettes that illustrate approaches to use these results to clarify AD-related pathways and potential therapeutics

Conformational Altered P53 As An Early Marker Of Oxidative Stress In Alzheimer's Disease, Laura Buizza, Giovanna Cenini, Cristina Lanni, Giulia Ferrari-Toninelli, Chiara Prandelli, Stefano Govoni, Erica Buoso, Marco Racchi, Maria Barcikowska, Maria Styczynska, Aleksandra Szybinska, D. Allan Butterfield, Maurizio Memo, Daniela Uberti

In order to study oxidative stress in peripheral cells of Alzheimer's disease (AD) patients, immortalized lymphocytes derived from two peculiar cohorts of patients, referring to early onset AD (EOSAD) and subjects harboured AD related mutation (ADmut), were used. Oxidative stress was evaluated measuring i) the typical oxidative markers, such as HNE Michel adducts, 3 Nitro-Tyrosine residues and protein carbonyl on protein extracts, ii) and the antioxidant capacity, following the enzymatic kinetic of superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GRD). We found that the signs of oxidative stress, measured as oxidative marker levels, were evident only in ADmut …

Are Baby Boomers Who Care For Their Older Parents Planning For Their Own Future Long-Term Care Needs?, Alison Kleppinger, Julie T. Robison

UCHC Articles - Research

A rapidly expanding number of baby boomers provide care to aging parents. This study examines associations between caregiver status and outcomes related to awareness and anticipation of future long-term care (LTC) needs using 2007 Connecticut Long-Term Care Needs Assessment survey data. Baby boomers who were adult child caregivers (n = 353) vs. baby boomers who were not (n = 1242) were more likely to anticipate some future LTC needs and to have considered certain financing strategies. Although baby boomer adult child caregivers more readily anticipate some future LTC needs, they are not taking specific actions. It is important to address …

Geriatric Home Makeover, Edward F. Ansello

Director's Editorials from Age in Action

Houses pose substantial risks for falling. Over half of all falls by older adults happen in their homes. Reducing hazards in the home addresses just one set of contributing risk factors involved in older adults falling.

Is Aging A Disability?, Edward F. Ansello

Director's Editorials from Age in Action

Growing older is not predictable decline, and the overwhelming majority age without acquiring disabilities. Because age does not equal disability, the Virginia Commission on Government Reform and Restructuring should not fold the Virginia Department of the Aging, the Department of Rehabilitative Services, and the Department for the Deaf and Hard of Hearing into one agency.

All The World's A Stage, Edward F. Ansello

Director's Editorials from Age in Action

Population aging is occurring worldwide because of success in attacking causes of infant mortality, improved public hygiene, and falling fertility rates; health care in later life itself has had only marginal impact in the numbers. Societies should appreciate the differences associated with being older but also deem to later life the value and protections given to other ages.

Walkability, Edward F. Ansello

Director's Editorials from Age in Action

A starting point for assessing how friendly or livable a community is, is to consider its walkability. Walkability has different dimensions, for it implies not only that there be amenities in the community to which one would want to go, but also that one can move about safely; that the person motivated would have the health status or needed support to move about; that there would be means of transportation within and outside of the community, such as public transportation and taxis.

Normal Pressure Hydrocephalus: How Can It Be Told Apart From Neurodegenerative Diseases Of The Elderly?, Raphael C. Zohn

The Science Journal of the Lander College of Arts and Sciences

Normal pressure hydrocephalus (NPH) affects more of the older population than people recognize. The underestimation of this neurological condition is due in most part to the overlap of its symptoms to other forms of dementia as well as many other geriatric conditions. The objective of this paper was to research and contrast various methods of differentiation in the diagnosis of normal pressure hydrocephalus as well as find pretreatment indicators of successful surgery. Methods included reviewing of articles and studies done to evaluate which symptoms are most commonly presented in normal pressure hydrocephalus and their subtle differences from the symptoms of …

Value Of A Graduate Gerontology Certificate Versus A Masters Degree, Janet S. Hahn

Academic Leadership Academy

The WMU Center for Gerontology was established in 2010 and builds on a strong tradition of gerontology education offered at WMU from the late 1970s to 2004. The undergraduate minor has been revised and is again offered. The previous graduate certificate in gerontology has not yet been reestablished.

This project sought to determine the relative value of a graduate certificate in gerontology vs. a masters degree in gerontology.

Neuroangiogenesis: A Vascular Basis For Alzheimer's Disease And Cognitive Decline During Aging, Charles T. Ambrose

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Angiogenesis directs development of the brain's microcirculation during antenatal and postnatal development, but its role later in life is less well recognized. I contend that during senescence a reduced cerebral capillary density accounts in part for the vascular cognitive impairment observed in many older persons and possibly for some forms of Alzheimer's disease. I propose that neuroangiogenesis is essential throughout adult life for maintaining the microcirculation of the cerebral cortex and elsewhere in the brain and that it commonly declines with old age. To support this hypothesis I have examined the neurological literature for relevant studies on cerebral capillary density …

Vitamin D Mitigates Age-Related Cognitive Decline Through The Modulation Of Pro-Inflammatory State And Decrease In Amyloid Burden, Teresita L. Briones, Hala Darwish

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Increasing evidence shows an association between the use of vitamin D and improvement in age-related cognitive decline. In this study, we investigated the possible mechanisms involved in the neuroprotective effects of vitamin D on age-related brain changes and cognitive function.

Methods

Male F344 rats aged 20 months (old) and 6 months (young) were used and randomly assigned to either vitamin D supplementation or no supplementation (control). A total of n = 39 rats were used in the study. Rats were individually housed and the supplementation group received a subcutaneous injection of vitamin D (1, α25-dihydroxyvitamin D3) 42 I.U./Kg …

Humor-Related Social Exchanges And Mental Health In Assisted Living Residents, Ann Elizabeth Mcqueen

Dissertations and Theses

Social contact is known to be vital for older adults' mental and physical health, but few studies of social interactions have taken place in long-term care settings. The current study investigated whether the psychological well-being of assisted living residents was influenced by factors associated with residents' social interactions involving humor. Specific aims of the present study were to develop and test a measure related to humor-related social exchanges, to examine how humor-related social exchanges affect residents' mental health, and to explore whether humor-related social exchanges mediated the effects of resident and facility characteristics on indices of mental health. One hundred …

Mild Cognitive Impairment: Statistical Models Of Transition Using Longitudinal Clinical Data, Erin L. Abner, Richard J. Kryscio, Gregory E. Cooper, David W. Fardo, Gregory A. Jicha, Marta S. Mendiondo, Peter T. Nelson, Charles D. Smith, Linda J. Van Eldik, Lijie Wan, Frederick A. Schmitt

Mild cognitive impairment (MCI) refers to the clinical state between normal cognition and probable Alzheimer's disease (AD), but persons diagnosed with MCI may progress to non-AD forms of dementia, remain MCI until death, or recover to normal cognition. Risk factors for these various clinical changes, which we term "transitions," may provide targets for therapeutic interventions. Therefore, it is useful to develop new approaches to assess risk factors for these transitions. Markov models have been used to investigate the transient nature of MCI represented by amnestic single-domain and mixed MCI states, where mixed MCI comprised all other MCI subtypes based on …

Cost Effectiveness Of A Home-Based Intervention That Helps Functionally Vulnerable Older Adults Age In Place At Home., Eric Jutkowitz, Laura N Gitlin, Laura T. Pizzi, Edward Lee, Marie P Dennis

College of Population Health Faculty Papers

Evaluating cost effectiveness of interventions for aging in place is essential for adoption in service settings. We present the cost effectiveness of Advancing Better Living for Elders (ABLE), previously shown in a randomized trial to reduce functional difficulties and mortality in 319 community-dwelling elders. ABLE involved occupational and physical therapy sessions and home modifications to address client-identified functional difficulties, performance goals, and home safety. Incremental cost-effectiveness ratio (ICER), expressed as additional cost to bring about one additional year of life, was calculated. Two models were then developed to account for potential cost differences in implementing ABLE. Probabilistic sensitivity analyses were …
