Are you a parent or guardian of an infant with Angelman Syndrome or Fragile X Syndrome? If so, please consider joining our non-invasive brain imaging study, which will help to advance our understanding of the earliest brain and behavior signs of these conditions. A copy of the MRI scan and a summary of behavioral assessments will be shared with the family. Compensation for participation will be provided, and all travel expenses will be covered.

Girls are almost 3 times more likely to develop mood disorders after the onset of puberty relative to males. This profound gender disparity suggests a critical role of ovarian hormones (such as estrogen) in the emergence of adolescent mood disorders. The purpose of the EVOLVE study is to learn about the effect of estrogen variation and stress in promoting mood symptoms during the pubertal transition.

We are looking for people who have survived a stroke on the left side of the brain and also volunteers who have not had a stroke. We want to learn about typical speech variation and differences that occur due to stroke.

Tripping while walking is very common after a stroke. The purpose of this study is to determine when a self-induced trip will occur.

Have you had a stroke? Did someone you care about have a stroke? If you are interested in participating in research studies related to stroke, you may join the UNC Stroke Research Registry. People on the registry may be called by researchers to find out if they want to participate in one or more studies related to stroke.

Teenagers with ADHD are more vulnerable to negative outcomes than teenagers without ADHD, in part because they engage in more extreme risk-taking. The goal of this study is to understand how brain development during puberty may contribute to risk-taking behaviors in adolescence, and how this differs in youth with and without ADHD. We also want to learn how to predict which children are more vulnerable to extreme levels of risk-taking when they become teenagers. This study will help us to identify children who may be at risk for negative outcomes so potential problems can be addressed early and ultimately prevented.

The study is being done to compare two ways of treating patients with a brain injury. At this time medical providers do not know if one way is better than the other. Both ways of treating patients are used in standard of care. None of the treatments in this study are investigational.

The purpose of this study is to investigate the health of former women's soccer players.

Do you have probable Dementia with Lewy Bodies (DLB), Mild Cognitive Impairment with "high likelihood" DLB, or Parkinson's Disease Dementia (PDD)? You may be able to participate in an observational study to track your disease progression and promote future research.

This study will gather information about patients who are taking new medicines for Alzheimer's disease. We'll keep an eye on how these patients are doing in the long run, tracking things like how they're responding to treatment, what their overall health outcomes are like, and how safe these new treatments really are when used in the real world. The goal of this study is to get a better understanding of how these therapies actually work for a diverse group of people, not just the people who usually participate in clinical trials.
