The probability of developing attention deficit hyperactivity disorder (ADHD) increases in children with epilepsy. The two disorders may have common causative factors. A bidirectional association between ADHD and epilepsy has been suggested in previous studies. Causative factors, such as those that are genetics and environmental, may be common in both disorders and cause several transcriptional changes in the brain, thus, altering behavior or cognition prior to seizures.
