Adolescents and adults alike can suffer from ADHD, a mental health condition. It's common for people with ADHD to come out as impatient, irritable, and impulsive. ADD/ADHD is a common adolescent disorder of the nervous system. It's most frequent in childhood, but it can affect people well into adulthood. When a child has ADHD, they may have difficulty paying attention, controlling impulsive behavior (doing without thinking about the consequences), or being overly active. You must include medication in your treatment plan if you want to see results. Doctors may prescribe a range of drugs to treat the disorder's symptoms.
