Attention deficit hyperactivity disorder (commonly known as ADHD) is a condition that makes people feel restless, impulsive and hyperactive. With symptoms typically showing up in childhood, those with ADHD often struggle to concentrate for long periods of time. While the condition is more commonly seen in children and teenagers, it can also affect adults.
Referred to as a behaviour disorder, ADHD can make everyday life difficult, especially for those at school. Key symptoms include hyperactivity, inattentiveness and impulsiveness. These tend to be noticed at an early age, often becoming more noticeable when a child's circumstances change (for example if there is a change in school).
The symptoms usually improve with age, however some adults continue to struggle. Sometimes the diagnosis isn't made and therefore learning to manage it can be difficult. The term ADD (attention deficit disorder) was used in the past, however it is generally no longer used. The criteria for ADHD changed to include the three subtypes described above, which includes what was currently in place to describe ADD (predominantly inattentive presentation).
