Effects of Stress, Sex Differences, and Cognitive Reserve on Cognitive Decline in Healthy Elderly Subjects
… it may be possible to similarly predict risk of cognitive impairment. To test this, the current study explored the cumulative effect of discreet psychosocial stressors that have occurred within the past year and their effect on changes in cognitive functioning as measured by individuals’ …

Influence of Age and Cognitive Reserve on Cognitive Function in HIV-infected South African Adults
… infected population. Globally, HIV-associated cognitive impairment is present in almost 45% of PLWH, with 72% of that total burden found in Sub-Saharan Africa (Wang et al., 2020). The severity and trajectory of that impairment is, however, influenced by numerous risk and protective factors. …

Identifying Factors Underlying Resilience to Age-Related Cognitive Decline
… is thought to contribute to the development of cognitive reserve which protects against the effects of detrimental age-related brain changes on cognitive performance. The research reported in this thesis uses a sensitive episodic memory task to detect relationships between lifestyle and memory …

Facilitating Healthy Ageing: Neuroprotective Effects of Mindfulness Practice
… to maintain focus on the breath while meta-cognitive awareness and executive control are required to detect and correct mind wandering. The purpose of this thesis was to investigate whether a simple, mindfulness based breath awareness meditation, administered over a short period to …

Predictors of Neuropsychological Status in Cardiac Patients
… While the fact that heart can negatively impact cognitive functioning is well documented, the factors that drive changes in cognition have not been studied in depth. Additionally, while many heart patients choose to enter cardiac rehabilitation (CR) programs designed to decrease morbidly and …

The effect of monolingualism, bilingualism and trilingualism on executive functioning in young and older adults
… to have, compared to monolinguals, enhanced cognitive control, consequently exhibiting greater cognitive reserve, which is thought to subsequently delay the onset of clinical expression of dementia. Based on recent evidence suggesting that the more languages one manages the greater cognitive …

Bridging cognitive gaps: development of novel diagnostic criteria for MCI in Multiple Sclerosis
… processes, predominantly affecting young adults. Cognitive impairment is a common but often underrecognized symptom of MS, affecting approximately 40% to 70% of patients. This impairment significantly reduces personal autonomy, limits work performance, and hinders active social participation, …

Gender differences in risk of neuropathology, cognitive decline and dementia in the Cognitive Function and Ageing Study (CFAS)
… literature suggest that women experience faster cognitive decline, a higher burden of Alzheimer’s disease neuropathological change (ADNC) and a greater impact of the Apolipoprotein E (APOE) ε4 risk allele. A focus on sex-linked biological factors, particularly oestrogen decline following the …

Factors affecting neuropsychological assessment in a group of South Asian older adults
… assessment is critical in the diagnosis of cognitive impairments in older adults. However, existing neuropsychological tests may not be suitable for minority populations. This thesis aimed to address this issue by recruiting cognitively-healthy South Asian older adults and assessing …

The role of premorbid factors and adverse childhood experiences in the persistence of symptoms post mild traumatic brain injury (persistent postconcussive symptoms)
… minority continue to experience various somatic, cognitive, and affective symptoms for months/years postinjury. Several biopsychosocial factors (e.g., cognitive reserve, psychiatric illness) may influence the persistence of postconcussive symptoms (PPCS). Adverse childhood experiences (ACE) may be …

Identifying Cognitive Profiles and Determinants of Cognitive Superaging Among Older Adults
Cognitive aging among older adults is heterogeneous and does not follow a single trajectory. This study used a person-centered approach to identify cognitive profiles, specifically cognitive superagers, among United States adults aged 75 and older and to quantify transitions between cognitive …

Benefit of Phonemic Cueing in Alzheimer's Disease Patients' Naming Performance: Baseline Correlates and Predictive Utility
… of naming deficits in AD and the underlying cognitive processes involved. The effects of providing cues during confrontation naming tasks have also been studied, and research has suggested overall benefits of phonemic cueing. This research project further investigated the benefits of phonemic …

PPARγ-pERK interaction restores memory consolidation in an Alzheimer’s disease model
Cognitive impairment is a quintessential feature of Alzheimer’s disease (AD) and AD mouse models. We and others have previously reported the peroxisome-proliferator activated receptor gamma (PPARγ) agonist rosiglitazone improves hippocampus-dependent cognitive deficits in some AD patients and …

Memory Fidelity in Healthy Ageing and Risk for Cognitive Decline
Memory decline is characteristic of cognitive ageing and it has been suggested that one important factor underpinning the magnitude of age deficits is a reduction in the fidelity or quality of perceptual and mnemonic representations. This thesis examined cognitive and neural underpinnings of …
