The DSM-5 has kept the same Attention-Deficit/Hyperactivity Disorder subcategories: 1) Inattention & Hyperactivity and 2) Impulsivity. Several minor changes have been made:

-Age of Onset: onset of symptoms has been changed from prior to age 7, to prior to age 12 in the DSM-5.

-Adult Diagnosis: only requires 5 instead of 6 of the 18 symptoms for diagnosis.
