ADHD is a well established condition in childhood, but much less attention has been given to this diagnosis among adults. It is estimated that 2-4% of the adult population has this condition. Adults with ADHD present symptoms that differ somewhat from those presenting in childhood and they are typically characterized by problems with planning of work and daily life activities as well as social persistence. The Adult ADHD Self-report Scale (ASRS) can be used in general practice as an introduction to the diagnostic process of ADHD in a psychiatry setting and to evaluate the effect of treatment. ASRS is now available in Danish and is recommended as a screener for adult ADHD.
