Aditya (name changed) was restless since pre-school; no task or activity ever held his interest for over a few minutes and he would often dart off without warning, seemingly unaware of dangers on a busy road or a crowded mall.

His mother was not concerned at that time. However, at 10 years of age, Aditya was as fidgety as a toddler and it became a struggle to get him to settle down for a simple task. His teacher also commented about his lack of attention and disruptive behaviour in class.
