The results of a recent study indicate that there are two types of attention-deficit/hyperactivity disorder (ADHD).  

One is known as “developmental ADHD” and is related to genetic factors.

The other appears to be linked to a “mild traumatic brain injury, such as a concussion.”  

Brain trauma such as a concussion is not out of the ordinary with 20 % of teens reporting a “mild traumatic brain injury.”

The study evaluated the “origins” of ADHD in 418 youth aged 8-22.

The results of the study indicate that understanding the source of the brain injury may determine different kinds of treatment.
