It's been a rough couple of days. Wednesday night he just had seizure after seizure. They put him into a drug induced coma and gave him super strong drugs to stop the seizures.
Thursday afternoon he had an angiogram. No clots, which is good. In fact he has really blood good flow, almost too good, which may be the cause of the seizures. So, they'll keep him asleep and on heavy anti-seizure meds until at least Sunday.
Being drugged for so long will definitely affect his development, at least temporarily, and we don't know what permanent damage, if any, the seizures did/are doing.
