Attention deficit hyperactivity disorder(ADHD) is a chronic condition characterized by impulsive behavior, attention, and hyperactivity. Most of the psychiatrists consider ADHD as a type of mental illness. It is a development condition of inattention and distractibility, with or without hyperactivity. ADHD evaluation is usually done in childhood, but symptoms can continue through adolescence and adulthood, so it may also be diagnosed for the first time in adults.
