A recent Canadian study published in the Journal of Psychiatric Research has found links between traumatic brain injury and a history of attention-deficit hyperactivity disorder. The study found that adults with traumatic brain injuries were more tan twice as likely than those without to report symptoms of ADHD. Researchers say that it is not surprising to find the connection between ADHD and TBI because some of the most persistent consequences of TBI include ADHD like symptoms, such as memory and attention impairment, deficits in executive function such as planning and organization, processing consonants and vowels and impulsive behavior.
There are two theories for the connection between ADHD and TBI:
1. TBI could result in psychoneurological changes that increase the chances of ADHD developing;
2. Having DHD could increase an individual’s risk of falling or having an accident that could cause a TBI.
More research is required in order to further the understanding of the association between ADHD and TBI and how it affects the development and treatment of both.
