ADHD/ADD is one of the most common mental health conditions affecting children and also many adults. Symptoms of ADHD may include inattention (not being able to keep focus), hyperactivity (excess movement that is not fitting to the setting) and impulsivity (hasty acts that occur in the moment without thought).
Many ADHD symptoms such as high activity levels, difficulty remaining still for long periods of time, and limited attention spans are common to young children in general. The difference in children with ADHD is that their hyperactivity and inattention are noticeably greater than expected for their age and cause distress and/or problems functioning at home, at school or with friends.
