ADHD symptoms and maturity - a follow-up study in school children.
(2010) In Acta paediatrica 99(10). p.1536-1539- Abstract
- Abstract Aim: To test the hypothesis that there is a subgroup of children with attention deficit hyperactivity disorder (ADHD) who show a decline in ADHD-symptoms that is associated with signs of biological maturation, a phenomenon referred to as a 'maturation catch-up'. Methods: The parents of 147 children who were given an examination in grades one and two 1999-2000 that included assessment of ADHD-symptoms and estimation of skeletal bone-age by use of hand radiographs (which was repeated in the eighth grade), were contacted 2008-2009 and were asked to answer questions concerning ADHD-symptoms and behavioural maturity in their children. The response frequency was 67%. A complete dataset was achieved in 57 children. A reduction of Conners... (More)

The response frequency was 67%. A complete dataset was achieved in 57 children. A reduction of Conners scores for ADHD-symptoms of eight or more between the evaluations was defined as a marked reduction in symptoms. Results: When the children with a marked symptom reduction (n = 6) were compared with children without such a reduction (n = 51), we found a significant difference in skeletal maturation (p < 0.05). Conclusion: This study gives support to the theory that there is a group of children with ADHD-symptoms who have a biological maturational-lag who will show a decrease in their ADHD-symptoms as they show a maturation catch-up with increasing age.
