Welcome to The OHSU Developmental

Attention disorders program

Joel Nigg, Ph.D., Director


OHSU operates a nationally recognized program, to study neurodevelopmental conditions related to attention-deficit/hyperactivity disorder or ADHD. 

ADHD is a neurodevelopmental condition characterized by extreme inattention, disorganization, overactivity, and/or impulsivity that is developmentally out of the normal range and impairs functioning.The program includes initiatives in several areas related to understanding this condition. These areas involve the committed expertise of several scientists at OHSU, as follows:
