Most people with ADHD have problems that fall into both these categories, but this is not always the case.
For example, some people with the condition may have problems with inattentiveness, but not with hyperactivity or impulsiveness.
This form of ADHD is also known as attention deficit disorder (ADD). ADD can sometimes go unnoticed because the symptoms may be less obvious.
Symptoms in children and teenagers
The symptoms of ADHD in children and teenagers are well defined, and they’re usually noticeable before the age of 6. They occur in more than 1 situation, such as at home and at school.
Inattentiveness
The main signs of inattentiveness are:

- 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
Hyperactivity and impulsiveness
The main signs of hyperactivity and impulsiveness are:
- 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

These symptoms can cause significant problems in a child’s life, such as underachievement at school, poor social interaction with other children and adults, and problems with discipline.
