Adult ADHD

🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the last 12 months.

1. Pharmacological interventions for ADHD: a systematic review and dose-effect network meta-analysis.

The Lancet. Psychiatry (2026) - Systematic Review / Network Meta-Analysis

Key Findings

  • Adult amphetamine efficacy plateaued above approximately 50 mg/day, while adult methylphenidate efficacy increased without clear plateau in sparse higher-dose data.
  • Discontinuation due to adverse events increased dose-dependently above 50 mg/day for adults receiving amphetamines or methylphenidate.

📋 Practice Implication: Use dose titration as an explicit shared decision: escalate when response is suboptimal, but reassess adverse-event risk before pushing beyond usual effective ranges.

2. Prevalence and moderators of personality disorders in adults with ADHD: A meta-analysis.

Psychiatry Research (2026) - Meta-Analysis / Review

Key Findings

  • At least one comorbid personality disorder was present in 57% of adults with ADHD, with estimates strongly influenced by specialized outpatient samples.
  • Passive-Aggressive, Avoidant, and Borderline personality disorders had the highest pooled co-occurrence rates at 25.3%, 23.1%, and 21.9%, respectively.

📋 Practice Implication: Screen for personality pathology when adult ADHD presentations include persistent interpersonal instability, avoidance, or emotional dysregulation, especially in specialty clinics.

3. Dialectical behavioral therapy for adult attention deficit/hyperactivity disorder: A meta-analysis of randomized controlled trials.

Psychiatry Research (2025) - Meta-Analysis

Key Findings

  • DBT moderately reduced adult ADHD symptoms versus controls, with a pooled standardized mean difference of -0.51.
  • Quality of life improved with DBT compared with controls, with a pooled standardized mean difference of 0.41.

📋 Practice Implication: Consider DBT skills-based treatment when emotional dysregulation, adherence barriers, or medication tolerability limit medication-centered ADHD care.

4. A meta-analysis of the intervention effect of cognitive behavioral therapy on adult ADHD.

Journal of Affective Disorders (2026) - Meta-Analysis

Key Findings

  • Across 14 RCTs, CBT improved core ADHD symptoms (SMD = -0.45), depressive mood (SMD = -0.23), anxiety/stress (SMD = -0.24), and executive function (SMD = -0.43).
  • CBT did not significantly improve quality of life (SMD = 0.12) or self-evaluation (SMD = -0.30), although CBT plus medication improved quality of life and anxiety/stress.

📋 Practice Implication: Frame CBT as a targeted intervention for symptoms, mood, anxiety, and executive skills, while separately addressing self-evaluation and broader life satisfaction.

5. Cognitive behavioral therapy effects on global functioning, domain-specific functioning, and quality of life in adult ADHD: A comprehensive meta-analysis.

Behaviour Research and Therapy (2026) - Meta-Analysis

Key Findings

  • CBT produced moderate improvements in global functioning after treatment (SMD = 0.47), increasing at follow-up (SMD = 0.67).
  • Occupational functioning improved most strongly, social functioning improved moderately, and academic benefits were limited; ADHD symptom improvement predicted quality of life but not functioning.

📋 Practice Implication: When functional impairment is the main treatment goal, target CBT exercises toward concrete work and social routines rather than relying on symptom reduction alone.

💡 Summary

Recent adult ADHD evidence supports individualized dose optimization for pharmacotherapy while expanding practical nonpharmacologic options. High-significance findings emphasize CBT and DBT for symptom, functional, and quality-of-life outcomes, alongside high rates of personality disorder comorbidity that should shape assessment and treatment planning.
