Within ADHD, some individuals experience difficulty with positive/approach emotions, negative/withdrawal emotions, or both.

Event-related potentials were collected from 109 adolescents (49 with ADHD) while they completed an emotional go/no-go task with three conditions: happy (positive/approach), fear (negative/withdrawal), and neutral.
