The purpose of this study is to determine if there are sex differences in seatbelt fit by quantifying male and female volunteers’ seatbelt fits relative to external body geometry and skeletal posture using an upright MRI.
This is an observational study designed to determine the relationship between quantitative advanced MRI measures and OCT with PET measurements of microglial activation and myelin health.
The CCNA COMPASS-ND study aims to investigate the bases, commonalities, and distinguishing characteristics of Alzheimer disease and related neurodegenerative disorders.
The purpose of this study is to compare abdominal weight gain and fat distribution to changes in brain morphology in people taking antipsychotic medications.
This trial will compare a novel form of rTMS, intermittent Theta Burst Stimulation to the standard conventional high frequency left sided stimulation protocol. The Left dorsolateral prefrontal cortex will be the site of stimulation in both treatment conditions. The site of stimulation will be targeted using MRI co-registration.
Parkinson's disease results from the loss of dopamine producing brain cells; however, the mechanism that start and continue this loss are still largerly unknkown. Recent research has suggested a protein called tau may contribute to the development and progression of Parksinon's disease. Using Positron Emission Tomography (PET), a brain imaging technique, we hope to determine if and how much tau is present in healthy control subjects. This control data will then be used for comparison for data collected in patients with Parkinson's and related diseases.
The purpose of this study is to determine the clinical, cognitive, motor, brain imaging, genetic and biochemical biomarker characteristics of Alzheimer disease (AD), subcortical vascular disease (SVaD) and mixed dementia (AD + sVaD).
