Chrissy,
Since your husband is an ENT Specialist, perhaps he has some connections with a neurologist's practice or can get her evaluated by the
ALS Clinic near you.

Most hospitals are not prepared to help someone with
ALS, as it is "rare" and the medical staff are not knowledgeable about the symptoms. If your mother is elderly, they may be chalking this up to old age.
It sounds like you have done the ground work of researching what may possibly be afflicting her, but only a neurological exam and testing will give you the answer. I hope you will be able to find the help that she sounds like she definitely needs.
