Full Answer

The National Institutes of Health lists some symptoms that are often experienced by people with ADHD. These can be categorized into three groups: inattentive symptoms, hyperactivity symptoms and impulsivity symptoms.

Some examples of inattentive symptoms include making careless mistakes in schoolwork, lack of attention to detail, not listening when addressed directly, failing to follow instructions and not completing chores or schoolwork. There can also be problems with organization, losing items and being forgetful. People who have mostly inattentive symptoms with few hyperactivity or impulsivity symptoms are often diagnosed with attention deficit disorder (ADD) rather than ADHD.

People with ADHD often have hyperactivity symptoms, which can include fidgeting, not being able to stay seated when it is expected, running around or climbing, talking excessively and not being able to work or play quietly.

Those with the third class of ADHD symptoms, which deal with impulsivity issues, typically exhibit behaviors such as blurting out answers to questions, interrupting others and not being able to wait for one's turn.
