my son was born with hypothyroidism,was treated a week later and still to this day,neurologist thought he may have autism also,but just recently he said it looks more like m.r.,he does not talk or show no way of communicating,when my son turned 2 i noticed his behavior was starting to change,he starting getting real aggresive towards himself and anyone around him,biting,pinching,scratching,pulling hair,it slowly progressed everyday,from maybe an hour a day till non stop now,he goes through these spells all day now with maybe a 30 min break in between,the doctor has him on risperdal,haldal,lorazapam,clonidine,benadryl,synthroid,nothing seems to be working,i am in the process of getting him admitted to a psyc ward to see if they can maybe help him,his neurologist says he has never seen a 2 yr old with this type of self injurous behavior in his 20 + yrs of working,can this be caused by thyroid issues?can this aggression ever go away or is my son going to have to live like this forever.we spend most of the day just trying to restrain him from hurting himself and myself.it has always seemed to me he has some kind of pain going on,they have done so many tests on him,mris,ekgs,fragile x,and lots of blood work,and everything keeps coming back negative,i dont know what else to do.when they admit him it seems like all they do is highly medicate him to calm him,which as soon as it wears off hes right back to it.what should i do?is there any other tests to be done.
