Hi,
I am so sorry about your mother but at the same time I am glad you found this forum where many excellent people (PALS and CALS alike) are willing to help you and your mother in this difficult journey.
Well, based on what you posted I take it your mother has Bulbar problems derived from ALS.
Bulbar problems affect the muscles of her face, the muscles for chewing, the muscles for swallowing and the tongue itself. That's why you and your father have problems trying to understand what she wants to tell you both.
As the muscles for swallowing get weaker, it becomes difficult for her to swallow solid food and, even more difficult to swallow liquids (water and thin liquids is the most problematic).
Now, may I respectfully ask you why didn't she get the PEG-tube? Was it because she didn't want to get it or something else?
Second question: After her ALS diagnosis was made, did she attend to the ALS Clinic regularly?
The ALS Clinic is necessary because there is a team of ALS experts (PT, OT, Speech Pathologist, Pulmonologist, Nurses, etc.) who work there and can monitor your mother and asses her needs based on what they observe when she attends to her appointments there.
There was (or is) a "window" to get the PEG-tube and it's based on the numbers of her FVC, which are determined by her Pulmonologist at the ALS Clinic. That's why is so important for Caregivers and PALS to attend their appointments at the Clinic.
Ultimately, I don't really know what to tell you. No one can really predict how long your mother is going to live, only God. However, the level of calorie intake she has right now is motive of serious concern.
Couldn't you call the people at the ALS Clinic and try to setup an appointment as soon as possible? If you can do it (and I am hopping you can) tell them what is going on and what advice/measures they can suggest you for you to help your mother in this difficult situation for all of you.
Look, I sincerely wish I could be more helpful to you or offer you a better advice/solution.
Let's hope other forum members (CALS and PALS) see this thread and can offer you better solutions and advice than I have.
Take care.
NH
