Attention deficit hyperactivity disorder (ADHD) is a condition that affects people’s behaviour. People with ADHD can seem restless, may have trouble concentrating and may act on impulse.
It is very difficult to diagnose ADHD in children younger than 5. That’s because many preschool children have some of the symptoms seen in ADHD in various situations. Also, children change very rapidly during the preschool years.
Symptoms of ADHD tend to be noticed at an early age and may become more noticeable when a child’s circumstances change, such as when they start school.
Most show signs of inattention hyperactivity or impulsivity in specific ways :
- Are in constant motion
- Squirm and fidget
- Do not seem to listen
- Have trouble playing quietly
- Often talk excessively
- Interrupt or intrude on others
- Are easily distracted
- Do not finish tasks
