There are three types of ADHD—hyperactive/impulsive, inattentive, and combined. People who are diagnosed with the inattentive subtype may have trouble paying attention or staying organized, but are not hyperactive. (Girls are more likely than boys to have the inattentive subtype, which is one reason their symptoms are often overlooked.) Many adolescents and adults with the hyperactive/impulsive or combined types of ADHD learn to control their impulsivity and hyperactivity, although they may still have problems with attention.
