Adult attention-deficit/hyperactivity disorder (ADHD) is a mental health condition exhibited by difficulty maintaining attention, as well as hyperactivity and impulsive behavior. Adult ADHD symptoms can lead to a number of problems, including unstable relationships, poor work or school performance, and low self-esteem.
ADHD always starts in early childhood, but in some cases it’s not diagnosed until later in life. It was once thought that ADHD was limited to childhood. But symptoms frequently persist into adulthood. For some people, adult ADHD causes significant problems that improve with treatment. (Mayo Clinic website)
