Attention-Deficit-Hyperactivity Disorder (ADHD)

ADHD belongs also to the group of neurodevelopmental conditions with onset usually occurring in childhood and adolescence. It manifests itself by problems with attention span and self-regulation and/or by impulsivity and high physical restlessness (hyperactivity). A clinical diagnosis is made when persistent symptoms are associated with impairments of functioning at home, school, workplace or during leasure time. However, symptoms alone are not sufficient for a diagnosis.

Attention Deficit Hyperactivity Disorder (ADHD) affects 5% of children and 4% of adults across Europe

ADHD may have different presentations. The predominantly inattentive presentation is characterized by being easily distracted, forgetful, daydreaming, disorganization, poor concentration, and having difficulty completing tasks. A predominantly hyperactive-impulsive type is marked by excessive fidgetiness and restlessness, hyperactivity, difficulty waiting and remaining seated, and immature behaviour. In case of a combined presentation, features of both inattentive and hyperactive-impulsive types are manifest.

ADHD co-existing with other neurodevelopmental conditions

ADHD and autism co-exist substantially, with a 20%-50% prevalence of ADHD in those with autism, and 30-80% of children with autism meeting criteria for ADHD. There is also clinical overlap between ADHD and ID.
