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 …

Behavioural Inflexibility And White Matter Inflammation In An Aged Happ Rat With Subcortical Stroke, Aaron M. Regis

Electronic Thesis and Dissertation Repository

The interactions between Alzheimer’s disease (AD) and ischemic stroke pathology are of key interest in the development of post-stroke cognitive decline. While clinical and experimental studies have suggested an interaction, the mechanisms whereby these conditions interact to worsen cognition haven’t been fully revealed. This study aimed to combine rodent models of AD and stroke in an aged rat and assess the behavioural and histological outcomes. An injection of endothelin-1 (ET-1), a potent vasoconstrictor into the basal ganglia of a rat with human amyloid precursor protein (hAPP) overexpression (F344Tg) was followed up 3 months later to assess behavioural flexibility, memory and …

Evaluating The Therapeutic Effect Of An Hsp90 Inhibitor In Mouse Models Of Alzheimer’S Disease, Bin Wang

Theses and Dissertations (ETD)

The excessive accumulation of amyloid peptides (Aβ) represents one major pathological hallmark of Alzheimer’s disease (AD), which is most notably characterized by synaptic dysfunction. Strategies targeting heat shock protein 90 (Hsp90) inhibition have been widely investigated in the treatment of cancer for over two decades. Its application in the treatment of neurodegenerative diseases however, has emerged more recently in the last decade. The role of the Hsp90 chaperone in clearing misfolded protein aggregates has been well established (in vitro only), but its function in synaptic activity remains elusive.

In our study, we utilized a widely used Hsp90 inhibitor, 17-AAG …

Alzheimer's Disease: Knowledge Of Early Detection, Risk Factors, And Treatment, Anna H. Smith, Katlyn S. Spadino

All Electronic Theses and Dissertations

Alzheimer's disease causes a progressive and irreversible decline in cognitive functioning. There are many people living with this disease, and the prevalence is expected to triple between 2010 and 2050. Many members of society are affected through either a personal diagnosis or the diagnosis of a family member. There have been numerous studies outlining risk factors, signs and symptoms, and treatments for this disease, but it is unknown if this has translated to greater public awareness. This study aims to assess the general adult population's knowledge of Alzheimer's disease. The participants are 35 to 70 years old and live in …

The Semantic Memory Imaging In Late Life Pilot Study, Michael Adam Sugarman

Wayne State University Dissertations

Introduction: Several functional magnetic resonance imaging (fMRI) studies have analyzed the famous name discrimination task (FNDT), an uncontrolled semantic memory probe requiring discrimination between famous and unfamiliar individuals. Completion of this simple task recruits a semantic memory network that has shown utility in determining risk for Alzheimer's disease (AD). Specific semantic memory probes using biographical information associated with famous individuals may build on previous findings and yield superior information regarding risk for AD.

Method: Sixteen cognitively intact elders completed the FNDT and two novel tasks during fMRI: Categories (matching famous individuals to occupational categories) and Attributes (matching famous individuals to …

Histological Evidence Of The Effect Of Oil Palm Phenolics In Atherogenic Diet Induced Rat Model Of Alzheimer’S Disease, Kenechukwu Monplaisir Monplaisir

Wayne State University Theses

BACKGROUND: Alzheimer’s disease (AD) is a neurodegenerative disease with the clinical presentation of memory loss and cognitive impairment. Alzheimer's disease pathology is the accumulation of beta amyloid plaques and neurofibrillary tangles.

METHOD: In this study atherogenic diet was used to induce AD in aged Brown Norway rats. The rats were assigned to the following four groups fed isocaloric diets; control group (C ),high cholesterol diet (H), high cholesterol + oil palm phenolics group (HP), high cholesterol + curcumin group (HC). The impact of oil palm phenolics (OPP) on neuronal health and its effect on amyloid deposition was evaluated using histology …

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. …

Curcumin/Melatonin Hybrids As Neuroprotective Agents For Alzheimer's Disease, John Saathoff

Theses and Dissertations

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the leading cause of dementia, affecting ~5.2 million Americans. Current FDA approved medications provide mainly symptomatic relief and there are no agents available to delay or cure this disease. Multiple factors such as amyloid-β aggregates, dyshomeostasis of biometals, oxidative stress, and neuroinflammation have been implicated in the development of AD. Even though significant advances have been made in understanding the mechanisms leading to AD, the exact etiology still remains elusive. Given AD’s multifactorial nature, a multifunctional strategy of small molecule design would help to identify novel chemical templates. Recently our lab …
