© 2018 The Author(s) The cholinergic neurons of the basal forebrain (BF) provide virtually all of the brain's cortical and amygdalar cholinergic input. They are particularly vulnerable to neuropathology in early Alzheimer's disease (AD) and may trigger the emergence of neuropathology in their cortico-amygdalar projection system through cholinergic denervation and trans-synaptic spreading of misfolded proteins. We examined whether longitudinal degeneration within the BF can explain longitudinal cortico-amygdalar degeneration in older human adults with abnormal cerebrospinal fluid biomarkers of AD neuropathology. We focused on two BF subregions, which are known to innervate cortico-amygdalar regions via two distinct macroscopic cholinergic projections. To …

Background: Alzheimer’s disease (AD) is a type of Dementia and a neurodegenerative disease that is characterized by the gradual degrading of both memory and cognitive functions. According to the World Health Organization (WHO), the prevalence of AD is increasing globally. Currently, AD is the sixth leading cause of mortality in the United States. As the ageing population increases in the United States, it is possible that AD will move up the ladder in the top cause of mortality. Although the prevalence of AD in most urban parts of developed nations such as the United States is widely known, little is …
The Famous Names Discrimination Task As A Biomarker Of Alzheimer's Disease Risk: An Erp Study, Elizabeth Rose Paitel
The Famous Names Discrimination Task As A Biomarker Of Alzheimer's Disease Risk: An Erp Study, Elizabeth Rose Paitel
Master's Theses (2009 -)
Current ERP research emphasizes age- and pathology-related declines in neural processing in the form of attenuated amplitudes and prolonged latencies. Notably, there is a gap in the ERP literature regarding neural processing trajectories in the time between healthy young adulthood and clinical MCI/AD samples. fMRI research, however, has demonstrated periods of increased, compensatory activation in healthy, cognitively intact APOE ɛ4 carriers both during resting state and event-related tasks (Bondi, Houston, Eyler, & Brown, 2005; Evans et al., 2014; Filippini et al., 2009; Rao et al., 2015), consistent with compensatory theories of cognitive aging (Cabeza, 2002; Park & Reuter-Lorenz, 2009; Reuter-Lorenz …
Factors Influencing Alzheimer's Disease Healthcare Utilization Patterns In Puerto Rico, Carlamarie Noboa
Factors Influencing Alzheimer's Disease Healthcare Utilization Patterns In Puerto Rico, Carlamarie Noboa
Walden Dissertations and Doctoral Studies
Alzheimer's disease (AD) is associated with substantial healthcare utilization costs, resulting in a public health priority. In this study, the relationship between the demographic characteristics of age, gender, and type of health insurance; the presence of comorbidities of older Puerto Rican residents diagnosed with AD; and their healthcare utilization patterns (i.e., medical office and emergency room visits and hospital admissions) was examined using Andersen's behavioral model. Data from the 2013 Puerto Rico Health Study was used in this retrospective cohort design study. All AD cases aged -?¥ 60 years were extracted using systematic random sampling. One-way ANOVA-WELCH, Mann-Whitney U test, …
