Understanding ADHD in adults

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects about 2.5 to 4% of adults worldwide. It is not only a childhood condition: 60 to 70% of children with ADHD still have significant symptoms as adults.

Adult ADHD looks different from childhood ADHD. Adults more often struggle with organisation, time management, prioritising and emotional regulation than with obvious hyperactivity. Many adults, particularly women, are not diagnosed until later in life. Effective treatments include stimulant and non-stimulant medication, cognitive-behavioural therapy, ADHD coaching and changes to the environment.

Frequently asked questions

What is the ASRS ADHD screener?

The Adult ADHD Self-Report Scale (ASRS-v1.1) was developed by the World Health Organization (WHO) in collaboration with researchers. The Part A screener consists of 6 questions that are the most predictive of ADHD symptoms. It is designed as an initial screening tool to help identify adults who may benefit from a full ADHD evaluation.

Can adults have ADHD?

Yes. ADHD is not just a childhood condition. Research shows that approximately 60-70% of children with ADHD continue to experience symptoms into adulthood. Adult ADHD affects an estimated 2.5-4% of the global adult population. It can significantly impact work performance, relationships, and quality of life. Many adults are diagnosed later in life, particularly women who may have been overlooked in childhood.

What happens after a positive ADHD screening?

A positive screening result means further professional evaluation is recommended, not that you definitely have ADHD. A comprehensive evaluation typically includes a detailed clinical interview, review of childhood and current symptoms, assessment of functional impairment, and ruling out other conditions. Treatment options include medication (stimulants and non-stimulants), cognitive-behavioural therapy, coaching, and organisational strategies.
