My son was 7 wks old when he went into cardiac arrest, and because of it he suffered from an anoxic brain injury, he was without oxygen for 45 minutes while cpr was performed on him. Despite medical opinions, he lived and is doing seemingly well. He is now 9 months old, and is social, babbles, crawls, but he is very impulsive, rough, and difficult to calm, and can not focus on anything for more then a few seconds at a time. He bites, and screams and is very loud loud beyond his control. I know it's not normal, his twin is nothing like that. Could this behavior be from his brain injury, and will it only become worse as he gets older? I'd like to know how to take preventive measures to stay a step ahead. Once we left the hospital after a few months, we were supposed to get another MRI to show if there's progressed brain damage, we decided against that because they would use anesthesia, which is what we felt caused him to go into cardiac arrest in the first place. I have no luck with neurologist, because they all suggest an MRI, but I am just scared to do that. I'd like any input , thank you
