The three forms of ADHD are: Inattentive, hyperactive and combined types
DSM IV describes 3 types of ADHD.
Inattentive, hyperactive and combined types Hyperactive and combination types of ADHD seem to be more frequent in boys. These children often disrupt class or respond impulsively to correction, which leads to referrals to professionals. The few girls who have been diagnosed with ADHD are more likely to have this type.
In early adolescence there tends to be a transition from Impuslive/hyperactive to inattentive
