The three most commonly recognised charctaristics are: inattention, hyperactivity, impulsivity . People who are inattentive have short attention spans. People who are hyperactive always seem to be in motion, multitasking but rarely achieving results. They can’t sit still and may feel constantly restless. Impulsive people seem unable to curb their immediate reactions or think before they act.
