Abstract

ADHD is a neurodevelopmental disorder in which noradrenaline and dopamine are decreased in the prefrontal cortex. Around 15–17% of ADHD cases persist into adulthood. ADHD is classified into three types: inattentive, hyperactive-impulsive and combined type. In researching ADHD trajectories, it has been found that there may be the so-called late-onset ADHD in which symptoms first emerge in teenagers and adults. Even if a child with ADHD “grows out” of ADHD in adulthood, there are still problems in everyday life in the person’s 30s. There are certain diagnostic criteria for diagnosing ADHD, which are based on problems in cognitive function and are expressed through decreased attention, working memory, response inhibition and motivation. These disorders cause problems in multiple areas of life including work, school and home. Treatment of adult ADHD has to be multimodal and multidisciplinary and, among other things, include treatment with stimulants or nonstimulants in order to improve the quality of life of the person with ADHD.
