  • Coaching and CBT add benefit.
  • An online GP can refer privately or via NHS pathways.

Symptoms in adults

  • Difficulty sustaining attention, easy distraction.
  • Restlessness, fidgeting.
  • Impulsivity in decisions or speech.
  • Disorganisation, missing deadlines.
  • Emotional dysregulation.
  • Lifelong pattern (since childhood).

Pathway

  • Self-screening (e.g. ASRS-v1.1).
  • GP referral to specialist ADHD service.
  • Specialist diagnosis and treatment plan.
