Dr.Wagner -> RE: April Case (April 18, 2008 8:01:26 AM)

Sorry for my late response, computer difficulties. This is a case of SYNCOPE. Basic and straightforward, this case is very common in teenage females much more than males. The keys in differential diagnosis vs a seizure is the lack of "post ictal phase" found in seizures. By definition syncope is the loss of postural tone with complete resolution of consciousness without neuologic sequele. You can have brief "seizure like" activity moments after the event, but this makes sense as syncope results in momentary cerebral anoxia. In this patients case it would be reasonable to perform an EKG and perhaps orthostatic blood pressure evaluation. With a normal neurologic exam, no special testing is needed. The lab testing done at the previous doctor visit was meant to show that this likely was not going to be pathological "zebra" and that no other testing would be needed.
