Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz

Theses

Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.

The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …

Attachment Security And Psychological Health In Adult Child Caregivers And Their Parents With Alzheimer’S Disease And Related Dementias, Wei Aiko Chang

Public Health Theses

Objective: Attachment theory is a helpful framework for examining one of the most fundamental needs in parent-child dyads across the lifespan and how attachment security might protect both dyad members’ psychological health, especially in times of crisis. In this study of adult child caregivers and their parents with early stage Alzheimer’s disease and related dementias (ADRD), we examined the associations between both dyad members’ attachment security, the adult child’s depressive symptoms, and quality of life of the parent with ADRD.

Method: Thirty-four individuals (parents) with ADRD and their 34 adult-child caregivers each completed the 12-item Experiences in Close Relationship Scale …

Factors Influencing Alzheimer's Disease Healthcare Utilization Patterns In Puerto Rico, Carlamarie Noboa

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is associated with substantial healthcare utilization costs, resulting in a public health priority. In this study, the relationship between the demographic characteristics of age, gender, and type of health insurance; the presence of comorbidities of older Puerto Rican residents diagnosed with AD; and their healthcare utilization patterns (i.e., medical office and emergency room visits and hospital admissions) was examined using Andersen's behavioral model. Data from the 2013 Puerto Rico Health Study was used in this retrospective cohort design study. All AD cases aged -?¥ 60 years were extracted using systematic random sampling. One-way ANOVA-WELCH, Mann-Whitney U test, …

A Story To Tell Among Minority Alzheimer's Patient Caregivers: A Phenomenological Study, Albertina Lashonda Walker

Walden Dissertations and Doctoral Studies

The level of burden experienced by caregivers of patients diagnosed with Alzheimer's disease is high. Studies that examine this burden by taking into account cultural and spiritual differences are limited, particularly with regard to minority populations. The purpose of this study was to investigate the burden and challenges faced by minority caregivers providing in-home care to Alzheimer's patients. Guided by social support theory, a phenomenological study design was used with semi-structured interviews of 12 caregivers to examine their perspectives on the burden and challenges they face, including their lived experiences, cultural and spiritual values, and interaction with health professionals. Thematic …

Mixture Modeling With Applications In Alzheimer's Disease, Frank Appiah

Theses and Dissertations--Epidemiology and Biostatistics

This dissertation involves an application of mixture of regression models to 114 individuals who are cognitively intact (from the Alzheimer's Disease and Neuroimaging Initiative-ADNI, data). The correct number of components in the model were estimated with the Singular BIC (SBIC), marking the first time it has been applied to such a problem. The smallest true model in conjunction with the approximation of SBIC was fixed at 1. The resulting posterior probabilities from the model were used to estimate the probability of a person transitioning and risk plots were obtained that could in principle be used by clinicians to identify patients …

Exploring The Lived Experiences Of Daughters/ Daughters-In-Law Providing Primary Informal Care To Their Mothers/ Mothers-In-Law With Dementia, Sarah Macfarlane

Theses and Dissertations (Comprehensive)

Abstract

Objective

As the senior population in Canada rises, more middle aged residents of Canada will find themselves taking on a caregiving role, often times for a parent with dementia. This research examines the lived experiences of daughters/daughters-in-law providing primary informal care to their mothers/mothers-in-law with dementia in order to understand the motivations, effects, and transitions within caregiving relationships.

Methods

Phenomenology was the theoretical orientation used to guide this research and captured individuals’ lived experiences. Background questionnaires were administered initially, followed by one-on-one semi-structured interviews which were transcribed verbatim upon completion for data analysis. Field notes, member checks, and triangulation …

Risk Of Alzheimer's Disease Among Older Hispanic/Latinos With Diabetes, Kathy Bianco

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is the 6th leading cause of death in older Americans. Currently there is no cure for AD, and even though the specific cause is unknown, diabetes mellitus type 2 (DM2) is regarded as a risk factor. Hispanics have a higher incidence of DM2 and possibly AD. I chose a life course theoretical model for this quantitative cross-sectional study to illuminate the variables most pertinent to a pathway from good health to poor health. The variables chosen were hypertension (HTN), obesity, smoking, stroke, dyslipidemia, and lower educational attainment. The research questions were used to examine biologic, metabolic, sociologic, …

An Examination Of Traumatic Brain Injury As A Risk Factor For Psychiatric Symptoms In Alzheimer’S Disease Patients, Jennifer F. Walch

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Introduction:

Dementia is a major public health issue both in the United States and worldwide. Alzheimer’s disease (AD) is widely considered to be the most prevalent type of dementia. While the hallmark AD symptom is profound memory loss, patients also commonly experience changes in personality and behavior. These changes often include depression, anxiety, social withdrawal, mood swings, irritability and aggression, changes in sleeping habits, and delusions.

Background:

Several studies have established a mechanistic link between traumatic brain injury (TBI) and the development of AD. However, it is unknown whether TBI contributes to the personality/behavior changes observed in many AD patients. …

Cultural Beliefs And Experiences Of Formal Caregivers Providing Dementia Care To American Indians, Damon Grew Syphers

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is a significant public health concern for all elders in the United States. It is a particular concern for the American Indian (AI) population, which is one of the fastest-aging populations in the United States and the smallest, most underrecognized, and most culturally-diverse group in the country. A formal caregiver understanding of AD in the AI population is scarce. This phenomenological study was designed to discern what is known about AD in the AI population by exploring the cultural beliefs and experiences of formal caregivers who provide care for AI dementia patients. Specifically, this study sought to …

An Evaluation Of Sample Size Re-Estimation Adaptive Designs And Delayed-Start Designs For Alzheimer's Disease Trials, Guoqiao Wang

All ETDs from UAB

The goal of this dissertation is to investigate the effect of novel clinical trial designs for Alzheimer's disease (AD), and to provide applications for their use in real trials. The data used for our simulation is a meta-data base of completed trials. In the first paper, we investigate the sample size re-estimation (SSR) adaptive design based on the effect size and the variance without taking into account the longitudinal feature of the trials. In the second paper, we take advantage of that feature to explore the SSR based on the variance of the rate of change in the longitudinal measurements. …

Glycemic Load And Risk Of Alzheimer's Disease: The Cache County Study On Memory, Health, And Aging, Eun Young Choi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carbohydrates are a major energy source for the human body and particularly glucose is the only energy source for the brain. Thus glucose metabolism is important to maintain normal brain function. Evidence showed insulin resistance and diabetes are associated with cognitive decline and a large amount of highly processed carbohydrate intake; in other words, a high glycemic load diet, which increases blood glucose faster and insulin demand, is associated with increased risk of insulin resistance and diabetes.

Based on this premise, the hypothesis that a high glycemic load (GL) diet increases the risk of incident Alzheimer’s disease (AD) was examined …

Correlates Of Knowledge And Locus Of Control On Burden In Professional Caregivers Of Alzheimer's Disease Victims In Three Institution Types, Ruth A. Manning-Gay

Community & Environmental Health Theses & Dissertations

In assessing professional caregivers of Alzheimer's Disease victims, this study tested whether, 1) knowledge would influence perceptions of burden in providing care to such patients, and if 2) individual locus of control would influence perceptions of burden in caring for; Alzheimer's I patients. Professional nurses (BSN's, RN's, and LPN's) from nursing banes, hospitals and psychiatric facilities were asked to complete a three part survey. Three instruments were utilized in this study: the Burden Self-Interview by Zarit, Reeves and Bach-Peterson and adapted for professional caregivers, a 15 item knowledge quiz and the North Carolina Internal External scale (short form) by Schopler, …
