Attention Deficit Hyperactivity Disorder with or without Hyperactivity (ADD or ADHD) is a neurodevelopmental disorder, which can present three principal symptoms:
- Attention deficit
- Hyperactivity
- Impulsiveness
It affects approximately 5 – 10% of the children and youth population, more frequently in boys than in girls. The majority of the cases can have a hereditary component.
Diagnosis and treatment are generally done in children around 7 years of age, however, in some cases diagnosis can be done before this age.
