ADHD refers to a group of behavioural symptoms that include inattentiveness, hyperactivity and impulsiveness. A short attention span, being easily distracted and restlessness are common symptoms. ADHD can occur in people of any intellectual ability although it is more common in people with learning difficulties. People with ADHD may also have additional problems, such as sleep and anxiety disorders.

Camden and Islington NHS Foundation Trust's Adult ADHD Service provides assessments in order to diagnose whether you have ADHD. The service is for adults 18+. Speak to your GP about a referral. 

Children with ADHD also have a wide range of other problem behaviours that can make them very difficult to care for, manage and teach. Children with ADHD may be overactive and impulsive, and often find it difficult to fit in at school. They may also have problems getting on with other children. Some children have significant problems with concentration and attention but are not overactive or impulsive. These children are sometimes described as having attention deficit disorder (ADD), rather than ADHD.
