Train the Brain Study: The purpose of this study is to investigate the effect of a web-based (remote, at home) computerized cognitive training protocol on cognitive performance in healthy older adults. Thetraining will involve a daily life situation in a multi-task context. If you are eligible, you will be asked tocomplete 13…
Condition: Healthy Volunteers
Investigator: Sharon Sanz Simon, PhD
Status: Closed
The purpose of this study is to investigate the effect of a web-based (remote, at home) computerized cognitive training protocol on cognitive performance in cognitively healthy older adults. The training will involve multi-tasking in a simulation of daily life situation. If you are eligible, you will be asked to complete 15 web-based sessions, 3 times a…

Investigator: Sheng-Han Kuo, MD
Status: Closed
Why? To evaluate how brain networks are affected when frequency-specific, non-invasive, brain stimulation is applied to people with ataxia or essential tremor as compared to healthy control subjects. Who? Healthy adults over the age of 40, who would like to participate as controls. What?…
Condition: Healthy Volunteers
Investigator: Jeffrey Miller, MD
Status: Closed
The purpose of this study is to use Positron Emission Tomography (PET) to identify changes in brain chemistry that may cause an episode of depression. This study will be carried out in approximately 30 subjects. PET is a technique that provides "pictures" of chemical connections in the brain by…
Condition: Healthy Volunteers
Investigator: Karen Bell, MD
Status: Closed
The purpose of this study is to test whether an investigational drug called solanezumab can slow the progression of memory problems associated with brain amyloid. The study will also test 1) whether the anti-amyloid treatment can slow evidence of AD-related brain injury on imaging tests to look…

Investigator: Gaurav Patel, MD, PhD
Status: Closed
The Dynamic Social Cognition Lab (DSCLab) is currently running a research study to map the parts of the brain involved in how we process social situations. This study involves a combination of clinical, behavioral and magnetic resonance imaging (MRI) sessions. The clinical and behavioral sessions include questionnaires about…

Investigator: Jonathan Posner, MD
Status: Closed
Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are typically treated with two types of medications: stimulants and non-stimulants. These medications work in different ways to treat ADHD symptoms, but we do not fully understand the brain mechanisms underlying the medications' effects. This study will use MRI…

Neurodegenerative diseases are conditions where the brain cells break down, causing mental and/or physical impairment. Alzheimer's Disease is a neurodegenerative disorder that affects millions of individuals and causes irreversible memory loss and cognitive impairment. Amyotrophic lateral sclerosis is also and incurable…
