Attention deficit hyperactivity disorder (ADHD)

ADHD and developmental disorders that can affect both children and adults. ADHD is typically characterised by difficulties in concentrating, problems with speech and actions, and impulsive behaviour. ADHD in particular is also associated with excessive energy and hyperactive behaviour, whereas those with ADD don’t tend to exhibit this hyperactivity and instead, tend to be more shy.

The symptoms of ADHD and ADD can vary from person to person, and also according to whether the sufferer is a child or an adult.
