Raising a child is a difficult process. Children can often be nonconforming, fidgety and even show signs of aggression. Sometimes these behaviours are persistent and suggest a more serious underlying issue. ADHD (attention-deficit/hyperactivity disorder) is a medical condition affecting millions of children worldwide. Symptoms include fidgetiness, self-focused behaviour, lack of focus and even aggression. Children with ADHD often develop depression and anxiety, they have trouble keeping their emotions in check (leading to outbursts), and their lack of focus leads to many unfinished tasks and trouble following instructions. To diagnose it, a doctor will carefully study your child’s behaviour for more than 6 months in multiple environmental settings.
