ADHD means Attention Deficit Hyperactivity Disorder. ADHD and gifted are conditions in children in which they tend to show some unusual behavioral differences from their mates. Attention deficit hyperactivity disorder and giftedness in children are most times confused for one another. The reason is because those two cases are seen as a kind of behavioral deviation. But the two are different.
A gifted child may have poor attention and easily gets bored when doing some things especially those things that won't add any value to him, while an ADHD patient does not even give attention to some basic activities. Gifted children are active when doing tasks, they consider to be helpful to them, but ADHD children are hyperactive due to their condition. And also, ADHD children easily lose focus on most things and they sometimes do things you don't expect from them, while gifted children tend to have more and intense concentration at anything they find themselves doing
