Gender Differences In Episodic Memory In Later Life: The Mediating Role Of Education, Sara Robinson

USF Tampa Graduate Theses and Dissertations

In the United States (U.S.), 14 million individuals aged 65+ are expected to be diagnosed with dementia by 2060, and women are nearly twice as likely to be diagnosed. Low education is a well-established risk factor for dementia and is hypothesized to partly explain the gender differences in late-life cognition. However, few studies have investigated education as a mediator of these gender differences. This study aims to investigate education as a mediator of gender differences in episodic memory using longitudinal data from the U.S. Health and Retirement Study (HRS). I used a sample of 35,721 respondents (20,190 women and 15,531 …

Early Indicators Of Cognitive Dysfunction: The Role Of Mild Behavioral Impairment, Hillary J. Rouse

USF Tampa Graduate Theses and Dissertations

Older age is associated with an increased risk for cognitively impairing diseases such as dementia. Despite significant research to find ways to cure this disease, there has been little success. However, a critical need when an intervention is discovered is a need to find ways to identify people who are at the greatest risk of developing dementia earlier in the disease process so that interventions can be implemented at that time. This could potentially lessen their risk or delay when they are diagnosed. Using longitudinal data from the National Alzheimer’s Coordinating Center (NACC), the aims of this current dissertation were …

Effects Of External Memory Aid Assessment And Treatment On Everyday Task Performance Of Individuals With Mild Neurocognitive Disorder, Alyssa M. Lanzi

USF Tampa Graduate Theses and Dissertations

Individuals with mild neurocognitive disorder complete many activities of daily living independently; however, they may require the use of compensatory strategies while performing everyday tasks. Compensatory strategies, such as external memory aids, incorporate a strengths-based approach to enhance the functional needs of individuals. Although external memory aids have a strong evidence-base, limited assessment tools and interventions are available to facilitate the development of individualized treatment plans that promote sustained strategy use. To better support the everyday needs of individuals with mild neurocognitive disorder and to inform clinicians who are developing interventions, the current dissertation includes four paper that examine a …

Selection Of Memory Book Content: Agreement In Content As A Function Of Informant Relationship To Memory Book Recipient, Rebecca J. Allen

USF Tampa Graduate Theses and Dissertations

This study was designed to determine to what extent provision of personally relevant information and sensory cues would agree between Recipient and Informant for selection of memory book content. Six dyads married to each other an average of 29.17 years (SD = 10.03), between the ages of 43 and 70 years (Mean = 57; SD = 8.39), and cognitively competent (i.e., no diagnosis of cognitive impairment) participated. Participants completed questionnaires independently and provided personally relevant information/memories, aversions towards select memories/topics, and sensory cues on behalf of themselves (as “Recipient) and their spouse (as “Informant”). For provision of personally relevant information/memories, …

Speed Of Processing Training Results In Lower Risk Of Dementia, Jerri D. Edwards, Huiping Xu, Daniel O. Clark, Lin T. Guey, Lesley A. Ross, Frederick W. Unverzagt

Psychiatry & Behavioral Neurosciences Faculty Publications

Introduction: Cognitive training improves cognitive performance and delays functional impairment, but its effects on dementia are not known. We examined whether three different types of cognitive training lowered the risk of dementia across 10 years of follow-up relative to control and if greater number of training sessions attended was associated with lower dementia risk.

Methods: The Advanced Cognitive Training in Vital Elderly (NCT00298558) study was a randomized controlled trial (N = 2802) among initially healthy older adults, which examined the efficacy of three cognitive training programs (memory, reasoning, or speed of processing) relative to a no-contact control condition. …

Hidden Markov Chain Analysis: Impact Of Misclassification On Effect Of Covariates In Disease Progression And Regression, Haritha Polisetti

USF Tampa Graduate Theses and Dissertations

Most of the chronic diseases have a well-known natural staging system through which the disease progression is interpreted. It is well established that the transition rates from one stage of disease to other stage can be modeled by multi state Markov models. But, it is also well known that the screening systems used to diagnose disease states may subject to error some times. In this study, a simulation study is conducted to illustrate the importance of addressing for misclassification in multi-state Markov models by evaluating and comparing the estimates for the disease progression Markov model with misclassification opposed to disease …

The Concept Of Missing Incidents In Persons With Dementia, Meredeth Rowe, Amy M. Houston, Victor A. Molinari, Tatjana Bulat, Mary E. Bowen, Heather Spring, Sandra Mutolo, Barbara Mckenzie

Nursing Faculty Publications

Behavioral symptoms of dementia often present the greatest challenge for informal caregivers. One behavior, that is a constant concern for caregivers, is the person with dementia leaving a designated area such that their whereabouts become unknown to the caregiver or a missing incident. Based on an extensive literature review and published findings of their own research, members of the International Consortium on Wandering and Missing Incidents constructed a preliminary missing incidents model. Examining the evidence base, specific factors within each category of the model were further described, reviewed and modified until consensus was reached regarding the final model. The model …

Embedded System Design For Real-Time Monitoring Of Solitary Embedded System Design For Real-Time Monitoring Of Solitary, Robert Philip O'Brien

USF Tampa Graduate Theses and Dissertations

Alzheimer's disease and other forms of dementia cause cognitive disabilities in the afflicted person. As a result, the person with dementia often requires assistance from a primary caregiver. However, while the caregiver is away from the home they are unaware of the person's status and may not be able to find out without returning to the home due to dementia's effects on cognition.

In this thesis work, a system of embedded devices is presented which tracks a solitary dementia patient in the home in real-time. The system is composed of three main hardware components. Multiple passive and active sensors are …

Supporting Speech-Language Pathologist Evidence-Based Practice Use: A Mixed-Methods Study In Skilled Nursing Facilities Within The Promoting Action On Research Implementation In Health Services Framework, Natalie Franko Douglas

USF Tampa Graduate Theses and Dissertations

As the management of dementia is a significant public health concern, efforts to increase access to effective treatments to a greater number of residents with dementia in skilled nursing facilities (SNFs) are warranted. The treatment addressed in this study, non-electronic external memory aids, is an evidence-based practice that has been found to increase positive communicative interactions and decrease negative behavioral problems of residents with dementia in SNFs.

Although use of memory aids is recommended, there are significant barriers such as lack of time and resources that inhibit the use of effective treatments in typical clinical settings. To address such barriers …

Sugar Consumption And Cognitive Aging In The Swedish Adoption/Twin Study Of Aging, Shyam Seetharaman

USF Tampa Graduate Theses and Dissertations

Abstract

Consumption of foods high in sugar content has been linked with the development of metabolic abnormalities such as cardiovascular disease and type II diabetes, major sources of global health concerns. Although the detrimental consequences of high intake of sugar on abnormal metabolic processes are established, it is not known how this association affects (or accelerates) cognitive aging.

The current project was based on data from the Swedish Adoption/Twin Study of Aging (SATSA) to test the hypothesis that high refined sugar intake contributes to accelerated trajectories of cognitive decline assessed longitudinally. Trajectories of cognitive change were assessed as a function …

Persons With Dementia Missing In The Community: Is It Wandering Or Something Unique?, Meredeth Rowe, Sydney S. Vandeveer, Catherine Greenblum, Cassandra N. List, Rachael M. Fernandez, Natalie E. Mixson, Hyo C. Ahn

Nursing Faculty Publications

Background: At some point in the disease process many persons with dementia (PWD) will have a missing incident and be unable to safely return to their care setting. In previous research studies, researchers have begun to question whether this phenomenon should continue to be called wandering since the antecedents and characteristics of a missing incident are dissimilar to accepted definitions of wandering in dementia. The purpose of this study was to confirm previous findings regarding the antecedents and characteristics of missing incidents, understand the differences between those found dead and alive, and compare the characteristics of a missing incident to …

Reducing Dangerous Nighttime Events In Persons With Dementia Using A Nighttime Monitoring System, Meredeth A. Rowe, Annette Kelly, Claydell Horne, Steve Lane, Judy Campbell, Brandy Lehman, Chad Phipps, Meredith Keller, Andrea Pe Benito

Nursing Faculty Publications

Background: Nighttime activity, a common occurrence in persons with dementia, increases the risk for injury and unattended home exits, and impairs the sleep patterns of caregivers. Technology is needed that will alert caregivers of nighttime activity in persons with dementia to help prevent injuries and unattended exits. Methods: As part of a product development grant, a randomized pilot study was conducted to test the effectiveness of a new night monitoring system designed for informal caregivers to use in the home. Data from 53 subjects were collected at 9 points in time over a 12-month period regarding injuries and unattended home …
