Distinguishing Between Alzheimer's Disease, Lewy Body Dementia, and Parkinson's Disease
The study is designed to characterize the clinical, neuropsychological, polysomnographic, and neuroimaging findings among subjects with Alzheimer's disease, Lewy Body dementia, and Parkinsons' Disease.
Autoimmune Features of Neurodegenerative Disorders
This study is being conducted to better understand the role of inflammation in Parkinson's disease (PD) and Alzheimer's disease (AD). The investigators plan to recruit 30 PD, 30 AD/Amnestic Mild Cognitive Impairment (aMCI), and 60 age matched healthy controls in this study to study the role of immune response in …
HOme-based Brain Monitoring With a GARment-EEG to Study Cognitive Decline in the Aging Population
This study will investigate the validity of the HOGAR EEG/PSG monitoring kit designed by Bitbrain as a tool for characterizing and assessing cognitive function in older adults, as well as for detecting and predicting cognitive decline. The kit consists of two EEG headbands and a mobile computing device that allows …
Swallowing Impairments in Adults With and Without Alzheimer's Disease
This research study is investigating whether people with Alzheimer's disease (AD) experience more changes to swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe AD is high (85-93%), yet little is known about how swallow function evolves throughout the disease course in people with AD. The …
A Study of Neurodegeneration and Neuronal Fluctuations in Lewy Body Disease and Alzheimer's Disease
The purpose of this research study is to investigate how the brain, memory, thinking, and motor behavior change both in individuals with movement and/or cognitive disorders, as well as healthy individuals. Researchers will look at measurements of memory, thinking, brain wave and muscle activity, daily functioning, and brain scans to …
Alzheimer"s Imaging Biomarkers in Obesity
High body fat at midlife, as evidenced by overweight or obese body mass index (BMI), is increasingly understood as a risk factor for Alzheimer's disease. However, the underlying processes and mechanisms that may underlie this risk remains unknown. With this project, the Investigator proposes to create a new cohort of …
Optical Neuroimaging and Cognition
Dementia is associated with a variety of neurovascular and neurometabolic abnormalities. Traditional imaging techniques used to investigate such abnormalities, such as Positron Emission Tomography and functional Magnetic Resonance Imaging, are not always well tolerated, have expensive start up and running costs, and are limited with regards to the types of …
Assessing Cognitive Decline at Home
Neuropsychiatric symptoms (NPS) refer to a range of mental and emotional issues that can be observed through how patients move, perform daily tasks, and express feelings on their faces. In this study, the investigators want to find ways to accurately and unobtrusively track these symptoms in people's homes over time. …
Biomarkers of Synaptic Damage in Multiple Sclerosis
A prospective and retrospective cohort study of about five years will be performed on blood and cerebrospinal fluid samples taken for diagnostic reasons from recruited patients within the Neuromed Neurology Unit. Subjects with other chronic neurodegenerative diseases such as Amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD) and Parkinson's disease (PD), …
Proteinopathies Expression in Skin of Neurodegenerative Disorders
The goal of this observational study is to compare the aggregation pattern of proteinopathies (alpha-synuclein, amyloid-beta, phosphorylated tau and transactive response DNA -binding protein 43 [TDP43]) in skin biopsies of patients with a neurodegenerative disease like Alzheimer's disease, frontotemporal lobe dementia, Parkinson's disease, atypical Parkinsonism, amyotrophic lateral sclerosis or normal …
