Children with attention deficit/hyperactivity disorder (ADHD) face a multitude of daily challenges. What’s more, many ADHD-related behaviours are not well understood by their peers, family and friends. These behaviours are often misinterpreted and mistakenly attributed to other unrelated aspects, such as rudeness, laziness or disinterest. To better understand this disorder’s characteristics and impact on children’s daily lives, it is essential to demystify ADHD-related behaviours. Understanding enables us to intervene more effectively and act more caringly. By doing so, we are able to be more patient and tolerant of these behaviours and, most importantly, know how to deal with them better.
