it was suggested to my son that he have neurtoxicology, hypoxia/anoxia & neuroimmunology screenings done, also to look for toxins/heavy metals, lead etc...what tests exactly do we request?? it seems that we can't get an answer nor much help from our pmd nor from the neuro dr. that he is seeing. he has been to brain matters in Colorado & had a pet scan done 1 yr ago & they suggested that we follow up at home, but again, we seem to be hitting a brick wall, all they want to do is to keep trying him on meds for bipolar which do not help him at all, the side effects are not worth keeping him on the meds.. He strongly feels that ther may be something else going on and possibly the testing may help us or let us know that there is nothing else. If possible, i would like to know exactly how these test are performed, the more info we have the better educated we are as to what to expect. i would greatly appreciate any help whatso ever.. we are just trying to get him well..thanks sooo much..
