Evaluating The Contributions Of State Of The Art Assessment Techniques To Predicting Memory Outcome After Unilateral Anterior Temporal Lobectomy, Tara T. Lineweaver, Harold H. Morris, Richard I. Naugle, Imad M. Najm, Beate Diehl, William Bingaman
Tara T. Lineweaver
Purpose:Although anterior temporal lobectomy (ATL) is an effective treatment for many patients with medically refractory temporal lobe epilepsy (TLE), one risk associated with this procedure is postsurgical decline in memory. A substantial number of past studies examined factors that predict memory decline after surgery, but few have investigated multiple predictors simultaneously or considered measures that are currently in use. Methods: This study compared the relative contributions made by presurgical neuropsychological test scores, MRI-based hippocampal volumetric analysis, and Wada test results to predicting memory outcome after ATL in a group of 87 patients. Results: Logistic regression analyses indicated that noninvasive procedures …
Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly
Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly
Dissertations, Theses, and Capstone Projects
A core feature of schizophrenia spectrum disorders (SSDs) is a basic sensory (e.g., visual, auditory) processing disruption, yet few studies have examined somatosensation. The current dissertation project examined somatosensory processes among individuals at varying degrees of psychometric risk for psychosis using tactile texture and spatial discrimination and letter recognition tasks. Differential patterns of associations of somatosensory abilities with schizotypal trait dimensions (positive, negative, disorganized), independent of anxiety and depressive symptoms, and the relative contributions of bottom-up (peripheral and morphologic features) versus top-down (error types) processing were examined. It was hypothesized that: 1) performance on somatosensory tasks would account for significant …
Cognitive And Emotional Abnormalities In People With Systemic Lupus Erythematosus, Philip Watson
Cognitive And Emotional Abnormalities In People With Systemic Lupus Erythematosus, Philip Watson
Dissertations, Theses, and Capstone Projects
Systemic lupus erythematosus (SLE) is a multi-system autoimmune disorder characterized by the production of autoantibodies (ABs). Approximately 30-50% of patients produce ABs directed against N-Methyl-D-aspartic acid receptors (NMDARs). Previous research with animals has identified these ABs as being associated with amygdala damage and a deficit in fear conditioning. People with SLE can have damage to the amygdala. This study aimed to determine if emotional processing deficits occur in people with SLE and to associate such deficits, if they exist, with anti-NMDAR AB presence, length of disease, cognition, and mood. Fifty-eight (11 AB+, 24 AB-, 23 healthy) women participated in tasks …
Brain Games As A Potential Nonpharmaceutical Alternative For The Treatment Of Adhd, Stacy Wegrzyn, Doug Hearrington, Tim Martin, Adriane Randolph
Brain Games As A Potential Nonpharmaceutical Alternative For The Treatment Of Adhd, Stacy Wegrzyn, Doug Hearrington, Tim Martin, Adriane Randolph
Adriane B. Randolph
Attention deficit hyperactivity disorder (ADHD) is the most commonly diagnosed childhood neurobehavioral disorder, affecting approximately 5.5 million children, of which approximately 66% take ADHD medication daily. his study investigated a potential nonpharmaceutical alternative to address the academic engagement of 5th through 11th grade students (n = 10) diagnosed with ADHD. Participants were asked to play "brain games" for a minimum of 20 minutes each morning before school for 5 weeks. Engagement was measured at three points in time using electroencephalogram, parent and teacher reports, researcher observations, and participant self-reports. An analysis of the data supports the hypothesis that daily use …
Examining A Novel Set Of Executive Function Measures Using Event Related Potentials, Danielle Cara Blinkoff
Examining A Novel Set Of Executive Function Measures Using Event Related Potentials, Danielle Cara Blinkoff
USF Tampa Graduate Theses and Dissertations
The nature and assessment of executive function are areas of active research. Many current assessments of executive function are complex, have limited reliability and validity, and suffer from task impurity, meaning other cognitive processes may indirectly influence task performance. Additionally, measures may be culture, language, or education bound limiting their use in certain populations (Miyake, Emerson, & Friedman, 2000; Miyake, Friedman, et al., 2000; Strauss, Sherman, & Spreen, 2006; Stuss, 2007). The purpose of this project was to develop a novel set of executive function measures to address issues with current clinical measures. The new measures 1) can be used …
Relationships Between Tests Of Visual Memory In Patients With Mild Cognitive Impairment And Alzheimer’S Disease, Guy Bernard Debros
Relationships Between Tests Of Visual Memory In Patients With Mild Cognitive Impairment And Alzheimer’S Disease, Guy Bernard Debros
Doctor of Psychology (PsyD)
Alzheimer’s disease (AD) is a degenerative neurological disorder characterized by cognitive and functional impairment (Budson & Solomon, 2011). Its prevalence is expected to rise in the upcoming decades as the world’s population ages (Alzheimer’s Association, 2014). Amnestic mild cognitive impairment (MCI) is a clinical diagnostic entity that may represent very early AD (Morris et al., 2001). Both disorders involve significant impairment in episodic memory, necessitating reliable memory measures when making diagnoses. Although verbal memory is most often impaired in the earliest stages of disease (Budson & Price, 2005), visual memory is also predictor of AD (Kawas et al., 2003). Partly …
Coordination Of Continuous And Discrete Components Of Action, Stephanie L. Kilian
Coordination Of Continuous And Discrete Components Of Action, Stephanie L. Kilian
ETD Archive
Goal-directed movement may contain discrete and continuous components of action. In this experiment, participants moved back and forth between targets using a computer mouse in a cyclical aiming task. It was of interest to examine the relation between a discrete button press on a computer mouse, indicating an attempt at target capture, and the peak position of the corresponding, continuous movement trajectory of the mouse. How might the spatial and temporal relations between those events vary as a function of variations in task constraints? In particular, this experiment varied the target width (W) and amplitude requirement (A), where variations of …
Neurocognitive Outcomes In Children Experiencing Seizures During Treatment For Acute Lymphoblastic Leukemia, Stephanie L. Nassar
Neurocognitive Outcomes In Children Experiencing Seizures During Treatment For Acute Lymphoblastic Leukemia, Stephanie L. Nassar
Electronic Theses and Dissertations
There is a growing literature for cognitive late effects among childhood cancer survivors, yet little empirical information is known regarding specific neurocognitive outcomes of children who experience seizures while treated for acute lymphoblastic leukemia. This study examined prevalence of on-protocol seizures, seizure risk factors, and neurocognitive change in children with therapy-related seizures in comparison to the normative sample and a matched cohort of children without on-protocol seizures. Participants included children enrolled on the St. Jude frontline leukemia treatment protocol, Total Therapy 15 (TOTXV) - the first systematic investigation of intensified chemotherapy agents plus optimal intrathecal therapy without irradiation. Out of …
Vascular Risk, Functional Connectivity, And Episodic Memory In Older Adults, Elizabeth Regina Tuminello Hartman
Vascular Risk, Functional Connectivity, And Episodic Memory In Older Adults, Elizabeth Regina Tuminello Hartman
Dissertations
Resting-state functional magnetic resonance imaging and functional connectivity (FC) analyses are used to explore functional brain networks underlying a diverse array of abilities. Functional networks are composed of regions throughout the brain whose activity is closely linked to form a coherent network. One functional network, the "default mode network" (DMN), is thought to subserve self-referential thought and autobiographical memory. DMN regions include the ventromedial prefrontal cortex, inferior parietal lobe, hippocampus, and the primary "hub" of this network, the posterior cingulate cortex (PCC). For reasons yet unknown, DMN FC declines in aging, which is associated with memory impairment. Vascular risk may …
