Exploring The Inter-Relationship Between Cognitive And Motor Function In People With Lower Limb Amputations, Humberto Adolfo Omaña Moreno
Exploring The Inter-Relationship Between Cognitive And Motor Function In People With Lower Limb Amputations, Humberto Adolfo Omaña Moreno
Electronic Thesis and Dissertation Repository
The main objective of the present dissertation was to expand our understanding of the inter-relationship between cognition and mobility in people with lower limb amputations (PLLA). Study 1 systematically reviewed the literature to assess the effects of dual-task testing on the balance and gait of PLLA. A total of twenty-two studies were included. Overall, PLLA demonstrated a disproportionately greater dual-task effect than controls, characterized by increased sway velocity and reduced pace and rhythm, and increased asymmetry when balance or walking was paired with a secondary task. Additionally, the dual-task effect was not influenced by differences in etiology, level of amputation, …
Functional Neuroimaging Techniques To Examine Falls And Cognition In Older Adults: A Systematic Review, Tia M. Seleem, Raphael Gabiazon
Functional Neuroimaging Techniques To Examine Falls And Cognition In Older Adults: A Systematic Review, Tia M. Seleem, Raphael Gabiazon
Undergraduate Student Research Internships Conference
Falls in older adults have been attributed to impaired cognition. There is potential for neuroimaging techniques to understand the biological components that are involved in the cognitive processes pertaining to falls. Therefore, the purpose of this systematic review was to analyze how functional neuroimaging can be used to examine the relationship between falls and cognition among older adults. The following five electronic databases were selected to identify peer-reviewed articles in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: 1) Medline (via OVID), 2) PsycINFO (via OVID), 3) CINAHL (via EBSCO), 4) EMBASE (via OVID), and 5) Pubmed. …
Examining The Association Between Brain Mri Measures At 7 Tesla And Cognition Following Covid-19 Infection, Helma Heidari
Examining The Association Between Brain Mri Measures At 7 Tesla And Cognition Following Covid-19 Infection, Helma Heidari
Electronic Thesis and Dissertation Repository
The long-term neuropsychological, cognitive, and neurobiological effects of the severe acute respiratory syndrome (SARS-CoV-2) in survivors with milder symptoms are still poorly understood. In this thesis we evaluated cognitive and psychological changes approximately five weeks after a wide range of symptoms in COVID-19 illness and determined whether advanced diffusion magnetic resonance imaging measures within subcortical brain structures of the limbic system were related to neurological, respiratory, psychiatric, and gastric symptoms experienced during the acute phase of illness. Cognitive and neuropsychological evaluations were performed in 45 participants who experienced neurological symptoms during the acute phase of COVID-19 illness. Participants also underwent …
Assessment Of Executive Function Using A Series Of Operant Conditioning Based Tasks In T1dm Rodents, Kevin T. Murphy
Assessment Of Executive Function Using A Series Of Operant Conditioning Based Tasks In T1dm Rodents, Kevin T. Murphy
Electronic Thesis and Dissertation Repository
This study examined the impact of Type 1 Diabetes Mellitus (T1DM) on executive function using a series of operant conditioning based tasks in rats. Sprague Dawley rats were randomized to either non-diabetic (n = 12; 6 male) or diabetic (n = 14; 6 male) groups. Diabetes was induced using multiple low-dose streptozotocin injections. All diabetic rodents were insulin-treated using subcutaneous insulin pellet implants. At week 14 of the study, rats were placed on a food restricted diet to induce 5 - 10% weight loss. Rodents were familiarized and tested on a series of tasks that required continuous adjustments to novel …
Interplay Between Shift Work, Psychological Distress, Sleep Quality, And Cognitive Performance, Rea Therese Alonzo
Interplay Between Shift Work, Psychological Distress, Sleep Quality, And Cognitive Performance, Rea Therese Alonzo
Electronic Thesis and Dissertation Repository
Shift work schedules are designed to maintain a continuous operation of goods and services. However, engaging in shift work may impact cognitive functioning. This thesis assessed the relationship between shift work and cognitive performance. Using cross-sectional data from the Canadian Longitudinal Study on Aging, multiple linear regression models were used to investigate the association between shift work and cognitive performance, as well as the moderating effects of psychological distress and sleep quality. Differences by sex and retirement status were also investigated. Shift work was significantly associated with poor performance for executive functioning but not for declarative memory. Poorer cognitive performance …
