Early Diagnosis Of Alzheimer’S Disease In The Primary Care Setting, Raymond R. Romano

Theses and Dissertations (ETD)

The burden of Alzheimer’s disease (AD) affects not just the individual but also families, providers, and society. Early recognition and diagnosis of AD may reduce cost by reducing interaction with the health care system, earlier initiation of treatment, and prolonging time to long- term care. Primary care providers, the first contact for diagnosis of patients with AD, are not fulfilling the potential of early diagnosis for a variety of reasons. Biomarkers of AD emerge on average 15 to 20 years before clinical diagnosis, yet currently established biomarkers are not easily available in the primary care setting. A growing body of …

Association Study: Apoe Alleles Association With Neurodegenerative Disorders In The Hispanic Population, Kimberly Moreno

Theses and Dissertations

The purpose of this study was to assess the impact of phenotypic variables and Apolipoprotein E (APOE) alleles and its effect on cognitive statues. APOE is a gene found vastly in the Hispanic community, speculated to be linked to neurodegenerative disorders such as Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI). Compared demographic, clinical, and genetic features among Hispanics who were diagnosed with Alzheimer's Disease, Mild Cognitive Impairment, and psychiatric disorders (e.g., anxiety and depression) in the efforts to assess the role of APOE. In past research, APOE has been considered a pathological hallmark for neurological diseases.

Past research has …

Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz

Theses

Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.

The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …

Challenges Of Doing Alzheimer’S Research In Costa Rica And Some Possible Solutions, Felipe Mejias

English Language Institute

Alzheimer's disease is a public health priority which has been researched for many years in the hope of finding a cure soon. Costa Rica has made significant progress in many areas of research; however, the research carried out in the country on Alzheimer's disease is very scarce. The present poster presents the challenges of developing scientific Alzheimer’s research in Costa Rica by reviewing current scientific research on Alzheimer's in Costa Rica and by conducting interviews with Costa Rican professionals who have conducted Alzheimer's research. The lack of investigative training of doctors, the difficulties in accessing patient data, and the lack …

Bilingualism/Multilingualism To Protect Against Cognitive Decline In Alzheimer’S Disease And Other Forms Of Dementia: A Systematic Review, Kirsten L. May

Honors Thesis

Given a growing incidence of Alzheimer’s disease and lack of treatments, prevention is a popular topic in both research literature (Angevaren et al., 2008; Orrell & Sahakian, 1995) and in news articles (Iacono et al., 2009). A cognitive reserve is a skill that improves cognitive functioning in executive controls. Bilingualism is believed to be a practice that increases cognitive reserve, which could delay the onset of Alzheimer’s disease.

The purpose of this project was to analyze the possibility that bilingualism or multilingualism could create a cognitive reserve to delay the onset of Alzheimer’s disease and other dementia-related diseases. This systematic …

© 2020, The Author(s). Changes to lipid metabolism are tightly associated with the onset and pathology of Alzheimer’s disease (AD). Lipids are complex molecules comprising many isomeric and isobaric species, necessitating detailed analysis to enable interpretation of biological significance. Our expanded targeted lipidomics platform (569 species across 32 classes) allows for detailed lipid separation and characterisation. In this study we examined peripheral samples of two cohorts (AIBL, n = 1112 and ADNI, n = 800). We are able to identify concordant peripheral signatures associated with prevalent AD arising from lipid pathways including; ether lipids, sphingolipids (notably GM3 gangliosides) and lipid …
