Symptoms include limited attention and hyperactivity. ADHD has nine main symptoms. these include being unable to sit still, especially in calm or quiet surroundings, constantly fidgeting, being unable to concentrate on tasks, excessive physical movement, excessive talking, being unable to wait their turn, acting without thinking, interrupting conversations,  And, little or no sense of danger. 

ADHD can cause kids in school to fidget around in their seats and talk whenever they feel like it even when not being spoken to, and do anything that keeps them moving like clicking a pen, and standing out of their seat randomly, and talking if it is feeling too quiet. They can tend to zone out because of the focus that they lack to stay on task and actually do what they were supposed to. This can cause bad testing and memory of what they learn in class. these traits could also tend to get them in some trouble because of talking out of turn or moving around when they are supposed to be seated. 

Though, this disorder can take a toll on people's lives, it can be treated. ADHD can be changed a lot over time, though rarely fully disappearing. This disorder can be worked through in a way that can make kids lives easier for them, as long as they have a support system of people who know what makes them think differently and what may help them to do better and work with what they have.
