Adult ADHD
Attention-Deficit/Hyperactivity Disorder (DSM-5-TR)
Persistent patterns of inattention, hyperactivity, and/or impulsivity that began in childhood and continue to cause functional impairment in adulthood. Adults often present differently than children — more internal restlessness than overt hyperactivity, chronic disorganization, emotional dysregulation, difficulty with sustained effort, and impaired time perception. Frequently comorbid with anxiety, depression, and substance use.
Prevalence: ~4-5% of US adults; ~2.5% worldwide; widely considered underdiagnosed
Clinical Picture
Adult ADHD is increasingly recognized as a condition that doesn't disappear after childhood but transforms — often into chronic struggles with organization, time management, emotional regulation, and a pervasive sense of underperformance relative to one's abilities. The shame associated with ADHD is often the primary therapeutic target: years of being told you're 'not trying hard enough' or 'not living up to your potential' create a self-concept organized around deficiency. Many adults are diagnosed late, and the diagnosis itself can be both relieving ('there's a reason') and grief-inducing ('all those years').
Treatment Considerations
Medication (stimulants, non-stimulant options) addresses the core neurobiological dimension and is often the most impactful single intervention. CBT for ADHD focuses on practical executive function strategies — organization systems, time management, breaking tasks into steps. But for many adults, the practical strategies don't stick until the emotional dimension is addressed: the shame, the compensatory anxiety, the relational patterns built around ADHD. ACT and mindfulness-based approaches help with the experiential avoidance and self-criticism that often accompany ADHD. Coaching (distinct from therapy) can address functional challenges directly.
