ADHD: An Evidence-Based Guide to Understanding, Assessment and Treatment

What is ADHD?

ADHD (attention deficit hyperactivity disorder) is a recognised neurodevelopmental condition affecting how the brain regulates attention, impulse and activity. Current neuroscience links it not to a simple lack of dopamine, but to differences in how the brain's networks coordinate. CBT for adult ADHD is superior to a waiting list (SMD 0.76) and to active control conditions (SMD 0.43). A 2023 meta-analysis of 28 studies found CBT reduced core ADHD symptoms, accompanying anxiety and depression, and improved self-esteem and quality of life. The Lyceum does not carry out ADHD assessments or prescribe medication. Written by Sanah Younis, BABCP-accredited CBT therapist.
