ADHD: Predominantly Hyperactive Type

Recognized in 1994, the predominantly hyperactive type of ADHD does not have sufficient inattentive challenges. It principally manifests difficulties with impulsive and hyperactive behavior. 

Research suggests this may not even be a separate ADHD type. Since up to 90% of cases are diagnosed as combined type within 3-5 years of initial diagnosis, it may be more an early developmental stage of combined type. 

Typical symptoms

    • Runs around or climbs excessively, especially smaller children
    • Fidgets with hands or feet 
    • Squirms in chair or has difficulty sitting still for long (for a meal or doing homework)
    • Feels extreme restlessness
    • Difficulty waiting or taking turns or engaging in activities quietly
    • Acts impulsivity, as if driven by a motor
    • Talks excessively and at inappropriate times, interrupts others and finds it hard to wait their turn or listen to directions
    • Grabs things from people
    • Has more accidents and injuries than others
