The Relation Between Hyperlipidemia, Hypertension, And Downstream Cognitive And Neuroanatomical Function, Victor James Wasserman

Theses and Dissertations

Objective: Cardiovascular risks (CVR) such as hypertension and hyperlipidemia play a critical role in the emergence of dementia syndromes. Medication to treat CVR may not obviate downstream risk for cognitive change.

Methods: To examine the relation between history of treatment with medications to treat CVR and cognitive outcomes, participants were seen at time points ~7 years apart, completed neuropsychological evaluations, assessed for history of treatment with medication associated with hypertension and hyperlipidemia as indicators of CVR, and classified into 3 groups: Not Treated, Inconsistently Treated, and Consistently Treated. Regression models associating neuropsychological outcome measures of cognition and CVR were explored …

The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette

Theses and Dissertations

The beneficial effects of exercise and cardiopulmonary fitness on general health, quality of life, and reduction of mortality are well known in older adults. There is evidence to support the positive effects of exercise and aerobic fitness on psychiatric and neurocognitive function in children, adults, and older adults. Indeed, many studies have explored the positive effects of aerobic fitness on slowing cognitive decline associated with normal and pathological aging. However, comparatively fewer empirical studies in the literature exist to support and understand the effects of aerobic fitness on the developing brain, particularly during adolescence and young adulthood, especially as it …

Psychometric Analyses Of A Comprehensive Neuropsychological Battery For Retired Nfl Players, Kimberly Ethridge Fitzgibbon

Theses and Dissertations

This study examined psychometric properties of the NFL Concussion Battery used to examine neuropsychological functioning in retired NFL players who were part of the NFL’s concussion settlement. This battery assesses multiple areas of cognitive functioning; executive functioning, language, processing speed, attention and memory. The study included 117 participants who were male with at least 16 years of education. The sample was 75.9% African-American and average age was 47. All participants completed the entire battery and passed the majority of effort measures. Those that did not pass the majority of effort measures or complete the entire battery were excluded.

A Novel Cognitive Stress Test For The Detection Of Early Alzheimer’S Disease In African Americans, Kimberly Capp

Theses and Dissertations

The U.S. population is currently undergoing a major demographic transition, with increasing racial and ethnic diversity of the older adult population. As the growing population of older adults advances in age, memory complaints are projected to increase in prevalence particularly among African Americans and present a challenge to clinicians who must differentiate between normal aging and progressive neurocognitive conditions (Celsis, 2000; Sherwin, 2000). As targeted therapeutic interventions and emerging therapies for AD are much more likely to be effective in the earlier stages of the disease (Loewenstein, Curiel, Duara & Buschke, 2017), early assessment and detection of AD, especially in …

Exploration Of The Wechsler Memory Scale Fourth Edition (Wms-Iv) Designs Content And Spatial Memory Scales, Maya Pinjala

Theses and Dissertations

The Designs subtest was newly added as a measure of visual memory to the Wechsler Memory Scale, 4th edition (WMS-IV). This study examined this measure in a mixed clinical sample (n = 158). Specifically, the aim of the study was to evaluate the publishers’ claims that the Designs test assesses both visual content (“what”) and spatial (“where”) memory, as these functions are processed within distinct neurological systems. To date, no studies have specifically examined the individual Content and Spatial scores in relation to other neuropsychological variables. The purpose of this study was to gain a more comprehensive understanding of the …

Head-Impact-Related Outcomes By Position In Retired Nfl Football Players, Maria Cecilia Boix Braga

Theses and Dissertations

This study examined how repeated head-impact-related traumatic brain injury experienced by retired NFL players impacts their neuropsychological functioning, as well as whether player position was a significant factor in the impairment experienced. Participants (N=142) were selected from an archival database gathered through the NFL Concussion Settlement belonging to the Neuropsychology Assessment Center of Nova Southeastern University.

One-Sample T-Tests indicated that the combined sample and the Skilled players group demonstrated significant differences in all neuropsychological measures, while the Linemen and Skilled Linemen evidenced impairment in most areas except in visual-spatial and non-timed language measures. Two-way ANOVAs indicated player position and ethnicity …
