Attention-deficit/hyperactivity disorder (ADHD) is a mental disorder that affects a person's ability to regulate their attention and behavior. People with ADHD may have difficulty paying attention, controlling impulsive behaviors, and may be overly active. These symptoms often lead to problems at school, work, and in social situations.

Symptoms of ADHD typically begin in childhood and can continue into adulthood. The exact cause of ADHD is not known, but it is thought to be related to a combination of genetic and environmental factors.

Treatment for ADHD often involves a combination of medication and therapy. Stimulant medications, such as Ritalin or Adderall, are commonly prescribed to help people with ADHD improve their ability to focus and control their behavior. Therapy, such as cognitive-behavioral therapy, can also be helpful in managing the symptoms of ADHD.

It's important for people with ADHD to work closely with a healthcare provider to develop an effective treatment plan. With proper treatment, people with ADHD can lead healthy, productive lives.
