NESCADE (“Neuroscreening for ADHD in School-Age Children”) is a new research project exploring innovative approaches to the early detection of attention-deficit/hyperactivity disorder (ADHD). Children with ADHD are to be identified using new screening methods even before they start school, so that appropriate support measures can be initiated early on. ADHD is one of the most common mental health conditions in childhood. Since diagnosis has typically only been made once noticeable behavioral patterns emerge, important windows of opportunity for prevention and targeted support are missed. The NESCADE project is therefore investigating how neurophysiological and behavior-based screening methods can enable earlier diagnosis. One focus is on the role of music training, which can have a positive impact on the health of children with ADHD. These approaches are designed to strengthen children’s individual development and social participation in the long term. The project plays a vital role in providing early support to affected children, promoting their mental health, and preventing future impairments.
