Pupil Size Tracks Attentional Performance In Attention-Deficit/Hyperactivity Disorder [PDF]
Scientific Reports, 2017 AbstractAttention-deficit/hyperactivity disorder (ADHD) diagnosis is based on reported symptoms, which carries the potential risk of over- or under-diagnosis. A biological marker that helps to objectively define the disorder, providing information about its pathophysiology, is needed.
