Attention deficit hyperactivity disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) is a behavioural disorder, sometimes also referred to as a neurodevelopmental disorder, which means that a person may have difficulties with inattentiveness, hyperactivity and impulsiveness.

A wide range of people experience ADHD. It is more commonly diagnosed in boys and is often noticed at a young age, but it can affect anyone, and be diagnosed at any age. ADHD is often initially recognised when children are in school between 6-12 years old.

Symptoms of ADHD

There are lots of symptoms associated with ADHD and they are usually present at both home and in school. Behavioural symptoms can be split into two areas: inattentiveness, and hyperactivity and impulsiveness.

The main symptoms of inattentiveness include:

  • having a short attention span and being easily distracted
  • making careless mistakes – for example, in schoolwork
  • appearing forgetful or losing things
  • being unable to stick to tasks that are tedious or time-consuming
  • appearing to be unable to listen to or carry out instructions
  • constantly changing activity or task
  • having difficulty organising tasks.

The main signs of hyperactivity and impulsiveness include:

  • being unable to sit still, especially in calm or quiet surroundings
  • constantly fidgeting
  • being unable to concentrate on tasks
  • excessive physical movement
  • excessive talking
  • being unable to wait their turn
  • acting without thinking
  • interrupting conversations
  • little or no sense of danger.

Often the symptoms become more manageable as children get older, however some adults continue to experience difficulties as they go through life.

Parents often feel concerned that ADHD is associated with bad behaviour and 'naughty' children, but ADHD is a medical condition that affects children in ways that can be beyond their control – and support is available to help.
