ADHD, or attention deficit hyperactivity disorder, is a mental health condition that causes a variety of symptoms related to a patient’s concentration and behavior. ADHD is most often diagnosed in children but can also occur in adults of both genders, especially if diagnosed and untreated during childhood. ADHD affects a person’s ability to retain information, focus, and concentrate. Patients with ADHD often have issues with controlling their behavior and paying attention. The condition occurs in both genders, although women sometimes present with different symptoms than men. Young women often go undiagnosed until early adulthood because they dismiss symptoms such as disorganization and poor attention, as something they are doing wrong instead of signs of an illness. There are three forms of ADHD: predominately inattentive, predominately hyperactive/impulsive, and a combination.
