Not a doc...so here are some thoughts: This depends on what specialist or person made the diagnosis. A person suffering from low thyroid can have a form of dimentia known as Cretinism, but taking thyroid hormone will correct the problem if caught early enough. If an emergency doctor makes a diagnosis of dimentia and does not state the specific cause...he/she may be in a bit of a hot spot as patients can show up with dimentia and they could be on a medication that has a side effect of dimentia or they could be on street drugs or be suffering from a metabolic disorder or head trauma....a good ER doc will get to the bottom of it if it is sudden!! The patient should see a Psychiatrist before accepting a permanent diagnosis of dimentia and even then the cause should be investigated...hardening of the arteries, lack of oxygen to the brain and Alzheimer's disease, etc.
