Attention Deficit Hyperactivity Disorder (ADHD)

Attention Deficit Hyperactivity Disorder (ADD/ADHD) is usually described as being made up of three core behaviours: inattention, distractibility, impulsivity and in up to 60% of cases, hyperactivity. In addition, there is a cluster of other behaviours which can be associated with ADD/ADHD including:

  • Social clumsiness
  • Poor co-ordination
  • Behavioural issues
  • Disorganisation
  • Poor emotional regulation
  • Poor self-esteem
  • Specific Learning Disabilities
  • Language difficulties


According to the Diagnostic and Statistical Manual (DSM-V) Attention Deficit/Hyperactivity Disorder has three sub types:

A Predominately inattentive type (problems of attention, learning and executive control)
B Predominately hyperactive-impulsive type (hyperactive, impulsive, poor self-control of behaviour)
C Combined type (a mix of both of the above)

The new DSM-V does not change symptom criteria, but prevalence must include at least 6 symptoms from either or both the above two groups, A or B. Age of onset in DSM-V must be before 12 and comorbidity with ASD (Autism Spectrum Disorder) is now allowed. Boys are six times more likely to be referred for help than girls. ADD/ADHD can be a hereditary condition.

There is no single medical, physical, or other test for diagnosing ADD/ADHD. To determine if you or your child has ADD/ADHD, the following tools may be used: a checklist of symptoms according to the diagnostic criteria; answers to questions about past and present problems; a medical exam to rule out other causes for symptoms; an educational/cognitive/psychometric/IQ/achievement assessment; rating questionnaires; observation at home and/or school.
