Types of ADHD
Children with ADHD are all individuals and no two are the same. However, they may be divided into two broad groups according to their presentation:
- Mainly Inattentive
- Mainly Hyperactive-Impulsive
(Some children may show a combined form)
Some of the behaviours that a child in these groups may show are:
Inattention:
- Often fails to give close attention to details or make careless mistakes in schoolwork, or other activities.
- Often has difficulty keeping concentration in tasks or play activities.
- Often does not seem to listen when spoken to directly.
- Often does not follow through on instructions and fails to finish schoolwork (not due to misbehaviour or failure to understand instructions).
- Often has difficulty organising tasks and activities.
- Often avoids, dislikes, or is reluctant to engage in tasks that require asustained mental effort (such as school work or homework).
- Often “loses” things necessary for tasks and activities e.g. toys; school books; pencils.
- Often easily distracted by things going on around them.
- Often forgetful in daily activities.
For a child to have a diagnosis of ADHD, six or more of the above must apply to a significant and inappropriate degree.
Hyperactivity/Impulsiveness:
- Often fidgets with hands or feet or squirms in seat.
- Often leaves seat in classroom.
- Often runs about or climbs excessively in situations in which it is inappropriate (in adolescence this may be restricted to feelings of restlessness).
- Often has difficulty in playing or engaging in leisure activities quietly.
- Often “on the go” or often acts as if “driven by a motor”.
- Often talks excessively.
- Often blurts out answers before questions have been completed.
- Often has difficulty waiting their turn.
- Often interrupts or intrudes on others (e.g. butts into conversations or games).
