Plateau Then almost unable to speak

On Monday the doctors assured us that Dad had plateaued. Visited him on Wednesday and chalked it up to his bad night and the fact I had not seen him for two days. You have to realize that we are only able to read his lips. I thought my two days away and his exhaustion made it harder to read him. Friday I realized I had been in denial. He cannot smile and I can only see his tongue moving. The muscle control in his mouth is nearly gone. I am so worried and confused because if he’s not able to communicate, he will get more depressed and anxious. We have a famiy meeting on the 28. So many questions so little answers. Anyone else had this experience where it has supposdly plateaued and then progressed?:confused:
