Adhd definition: Attention, Deficit Hyperactivity Disorder is a mental disorder that affects how people process information. It can cause problems with focus, hyperactivity, and impulsiveness. ADHD is one of the most common mental disorders in the United States, affecting around 6.4% of adults and 3% of children. There are three main symptoms of ADHD: difficulty focusing, hyperactivity, and impulsiveness.
People with ADHD have difficulty focusing on tasks that they find uninteresting. This can lead to problems in school and at work and decreased productivity. In order to focus, people with ADHD need a lot of stimulation. They may fidget or move around a lot, and they may be easily distracted by noises or movements. It is usually diagnosed in children when they are having difficulty paying attention, controlling their behavior, and sitting still. However, adults can also be diagnosed with ADHD.
