Role of Caregiver Beliefs About Alzheimer Disease in the Social Creation of Dependency Among Persons With Alzheimer Disease
DownloadFall 2012
It is estimated that over 1.1 million people in Canada will have dementia by 2038 (Alzheimer Society of Canada, 2010). In the caregiving context it is important that independence be maintained for as long as possible. Previous research has shown that caregivers can inadvertently create excess...

Selected Health Factors (Pulse Pressure, Type 2 Diabetes) and Genetic Polymorphisms (ApoE, IDE rs6583817) Play Independent and Interactive Roles in Patterns of Cognitive Performance and Change in Older Adults
DownloadSpring 2014
Objective: This gene x environment (health) dissertation focused on concurrent and longitudinal change in performance on executive function (EF) and declarative memory (DM) latent variables by normal aging adults. Specifically, we report three studies that tested the independent and interactive...

Fall 2016
Apolipoprotein E (APOE) ɛ4 and Clusterin (CLU) C alleles are risk factors for Alzheimer’s disease (AD) and preclinical cognitive and memory decline in older adults. We investigated whether memory resilience to genetic risk (i.e., Apolipoprotein E [APOE] ɛ4, Clusterin [CLU] CC, and a high additive...

Skeletal Muscle Sympathetic Vasoconstrictor Control Following Short-Term Mild- and Heavy-Intensity Exercise Training
DownloadFall 2013
The purpose of this thesis was to investigate the effects of short-term endurance exercise training (ET) on sympathetic vasoconstriction in resting and contracting skeletal muscle. To achieve these aims, rats were exercise trained on a motorized treadmill and an anesthetised whole animal in situ...

Stroke Prevention in Middle-Aged and Older Arab Immigrant Women: Emphasizing Strengths and Identifying Challenges
DownloadFall 2017
Arab immigrants constitute a minority group that is increasing in Canada. Minimal literature exists on Arab immigrant women’s experiences of ageing while managing health concerns. The evidence suggests that stroke risk factors are on the rise in this population with a lack of supportive resources...

Structural changes of the amygdala subnuclei and limbic white matter tracts in healthy aging and major depressive disorder
DownloadFall 2019
The world population is dramatically aging. Several factors affect brain in healthy aging. The apolipoprotein E (APOE), brain-derived neurotrophic factor (BDNF) and catechol-O-methyl transferase (COMT) might be involved in neurodegenerative diseases, depression and cognitive decline in healthy...

Synergistic Associations of Genetic, Demographic, Health, and Lifestyle Risk Factors on Neurocognitive Performance and Change in Aging
DownloadSpring 2016
Objective: Neurocognitive phenotypes observed in aging have been linked to select combinations of candidate genetic polymorphisms and modifiable risk factors. In this dissertation, I test multiple methods and approaches to examine three modifiable risk domains (i.e., demographic, health,...

The effect of aerobic fitness on the cardiovascular and sympathetic nervous system response to physiological stress at rest and during dynamic exercise
DownloadFall 2012
A cardio-protective adaptation associated with aerobic fitness may be an attenuated sympathetic nervous system (SNS) and cardiovascular response to stress. The hypothesis that the cardiovascular and SNS responses to physiological stress at rest and during exercise would be a function of...

The effect of eight weeks of home based aerobic exercise training on peak exercise oxygen consumption, six-minute walk test distance, thigh muscle mass, and health related quality of life in Child Pugh class A and B cirrhosis patients
DownloadFall 2017
Purpose: Cirrhosis patients have reduced peak aerobic power (peak VO2) that is associated with reduced survival. Supervised endurance training is an effective therapy to increase exercise tolerance in cirrhosis. The effect of home-based endurance exercise training (HET) on improving peak VO2 in...

Spring 2018
Purpose. The present study focused on modulating features of speech motor control using transcranial direct current stimulation (tDCS). Recent studies have shown that tDCS modulates cortical activity within the brain, leading to changes in both cognitive and motor performance. More specific to...
