However, when their immune system is not working properly (people who have had a transplant and those who have immune disorders), EBV can cause certain…
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 scanning to look at changes in…
Obssesive Compulsive Disorder (OCD) and related disorders characterized by repetitive thoughts and behaviors (e.g., Tourette Syndrome and EatingDisorders) are severe conditions that lead to significant health-related disability. Dysfunction in the brain circuits…
