Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your son s brain has been damaged since birth (probably perinatal hypoxia). This damages to his brain, are not only the cause of motor deficits and a delayed psycho-motor development, but also can cause seizures, as a result of the dysfunction of those brain regions. You should know that seizures in this case are more probable to occur during the first years of life, but can also occur later. A head trauma can induce them, as it can cause a new imbalance in the brain cell function and inflammation. If he starts having seizures, the treatment with antiepileptic drugs should be started, to prevent further recurrent seizures. Hope to have been helpul! Best wishes, Dr. Aida
