Attention-deficit/hyperactivity disorder (ADHD) in the course of life.

ADHD is a pervasive disorder that extensively impairs the quality of life and that can lead to serious secondary problems. Contrary to the prior assumption long-term studies have demonstrated that the disorder is not limited to childhood and adolescence. Unfortunately appropriate criteria for adults with ADHD are not given in the ICD-10. The clinical experience indicates substantial difficulties of adults, whose ADHS is not diagnosed and treated. They often cause extensive costs for the welfare system. The evidence-based psychiatric treatment is highly effective and inexpensive.
