Current Studies

  • Imaging Study of Stimulant vs. Non-Stimulant Treatment of ADHD
    Principal Investigator: Jonathan Posner, PhD. This MRI study will examine the mechanisms by which nonstimulant and stimulant medications reduce symptoms of ADHD. This study is currently recruiting children with ADHD, as well as healthy children, between the ages of 6 and17.
  • How Do Stimulant Medications Treat Symptoms of ADHD?
    Principal Investigator: Jonathan Posner, PhD. In this MRI study, we are investigating the mechanisms by which stimulant medications like lisdexafetamine (also known as LDEX or Vyvanse) reduce symptoms of ADHD. This study is recruiting individuals between the ages of 6 and 25, both those with a diagnosis of ADHD and healthy individuals without any mental health conditions. 
  • Brain Imaging Study of Emotion Regulation in Youth with Anxiety
    Principal Investigator: Jiook Cha, PhD. This MRI study will test whether anxious youth regulate their emotion (for example, fear) using brain imaging techniques.
