ADHD stands for Attention Deficit and Hyperactivity Disorder.
It is characterised by difficulties in the areas of attention, level of activity and impulse control. For a diagnosis, these core symptoms should be present by the age of 7 years, even if they’re not recognised until later in the child’s life.
ADHD is sometimes called “hyperkinetic disorder”. It is also, at times, referred to as “attention deficit disorder” (ADD) if problems are mainly due to difficulties with attention rather than overactivity.
