What is ADHD in adults?

ADHD is a neurodevelopmental condition affecting the brain’s self-regulation and attention systems. In adults it may look less like the “hyperactive child” stereotype and more like chronic disorganisation, procrastination, forgetfulness, restlessness and difficulty focusing – or hyperfocus on the wrong things. Symptoms must have been present since childhood (even if undiagnosed) to meet the criteria.

How is adult ADHD diagnosed?

ADHD is diagnosed clinically by a psychiatrist or trained clinician, not by an online test. The assessment reviews your history (including childhood), current symptoms across more than one setting, and rules out other causes such as anxiety, depression, thyroid problems or chronic sleep deprivation, which can mimic ADHD. Standardised rating scales and input from people who know you may be used.

How is adult ADHD treated?

  • Medication: stimulants and non-stimulants can improve focus and impulse control (prescribed and monitored by a doctor).
  • Therapy: cognitive behavioural therapy (CBT) helps with habits, planning and emotional regulation.
  • Coaching and routines: calendars, reminders, breaking tasks down, and reducing distractions.
  • Lifestyle: regular exercise, good sleep and structure support treatment.

Treatment is highly individual; what works varies from person to person, so work with a professional to find the right plan.
