Attention Deficit Hyperactivity Disorder is an executive function disorder that creates difficulties for a person to order their attention and prioritise activities which can result in chaotic behaviour. The symptoms of ADHD can be categorized into two types of behaviour: Innattentiveness and /or hyperactivity and impulsiveness. (NHS website)
The Attention Deficit Disorder Association (ADDA) defines it as follows:
ADHD is ‘a highly genetic, brain based syndrome that has to do with the regulation of a particular set of brain functions and related behaviour, such as attention, concentration, memory, motivation and effort, learning from mistakes, impulsivity, hyperactivity, organization and social skills. Oppositional Defiant Disorder (O.D.D) Oppositional Defiant Disorder is a persistent pattern of angry and aggressive behaviour that resists authority.
It is distinct from the usual childhood development of the will in that it becomes an overt and pervasive characteristic. It is often associated with ADHD.
