ADHD & Attention Research

This study will help us design better assessment and treatment for children with learning and attentional problems.


Attention Deficit Hyperactivity Disorder (ADHD) is defined by unexplained:

  • Inattention and Disorganization
  • Impulsivity and Hyperactivity
  • Persisting over time and situation
  • Not consistent with developmental level or age

ADHD affects about 5% of school-aged children worldwide and in the U.S.

Boys are two times as likely as girls to be identified.

All socioeconomic groups, nations, and cultures are affected.

As a very early onset, chronic, and common disorder, ADHD is associated with as much individual and societal burden as virtually any disease in the U.S. Treatments cannot cure the disorder, but only suppress symptoms. No known prevention or cure exists. The ADHD Program at OHSU seeks to identify better diagnostic tools, discover causes, and inform improved assessment, treatment, and prevention.
