Testing The Efficacy Of Transcranial Magnetic Stimulation (Tms) In Treating Depression In Patients With Cognitive Impairment, Daniel Robert Schaffer Jul 2018

Testing The Efficacy Of Transcranial Magnetic Stimulation (Tms) In Treating Depression In Patients With Cognitive Impairment, Daniel Robert Schaffer

Psychology Theses & Dissertations

The purpose of this study is to (1) examine the efficacy of Transcranial Magnetic Stimulation (TMS) in treating depression among individuals with cognitive impairment and (2) to examine if TMS is capable of facilitating cognitive improvements independent of mood improvements. Mild cognitive impairment (MCI) is often seen as a pre-clinical stage to dementia, and depressive disorders are highly prevalent among both MCI and dementia. There is a large body of research that has linked depressive disorders as a prodromal symptom of MCI and the later development of dementia. While some researchers debate whether or not this link between depression and …


The Effects Of Cognitive Training Among Individuals With Neurodegenerative Diseases, Elise Gabriela Valdes Jun 2016

The Effects Of Cognitive Training Among Individuals With Neurodegenerative Diseases, Elise Gabriela Valdes

USF Tampa Graduate Theses and Dissertations

With the growing older adult population, neurodegenerative diseases common in old age such as mild cognitive impairment (MCI) or Parkinson’s disease (PD) are becoming increasingly germane areas of research. Pharmacological treatments have thus far been unsuccessful in treating cognitive decline associated with these neurodegenerative disorders. Alternative interventions, such as cognitive training programs, have shown promise. The current dissertation contains three papers examining cognitive interventions in neurodegenerative diseases. The first paper examined the longitudinal effects of cognitive speed of processing training (SPT) among those with PD. Results showed that training gains seen at initial post-test were maintained three months later. The …

This study examined the functionality of the medial temporal lobe (MTL) and posterior cingulate (PC) in mild cognitive impairment amnestic type (MCI), a syndrome that puts patients at greater risk for developing Alzheimer disease (AD). Functional MRI (fMRI) was used to identify regions normally active during encoding of novel items and recognition of previously learned items in a reference group of 77 healthy young and middle-aged adults. The pattern of activation in this group guided further comparisons between 14 MCI subjects and 14 age-matched controls. The MCI patients exhibited less activity in the PC during recognition of previously learned items, …

Background: Several previous studies have reported that amnestic mild cognitive impairment (aMCI), a significant risk factor for Alzheimer's disease (AD), is associated with greater atrophy in the medial temporal lobe (MTL) and posterior cingulate gyrus (PCG). Method: In the present study, we examined the cross-sectional accuracy (i.e., the sensitivity and specificity) of voxel-based morphometry (VBM) in discriminating individuals with MCI (n = 15) from healthy age-matched controls (n = 15). In addition, we also sought to determine whether baseline GM volume predicted aMCI patients that converted to AD from those that did not approximately 2 years after the baseline visit. …
