I think I've discovered part or maybe all of the problem. I brought the plant over to my florist-friend for repotting and he noted the soil was bone-dry. This, despite the fact that I had just watered the plant to seemingly saturation the day before. Apparently, the watering may have been just making its way around the edge of the pot but never getting the soil wet for drinking purposes. He informed me it wasn't uncommon. Anyway, we repotted with nice moist soil. I do hope "mom" revives. I will keep you all posted and thanks for your generous advice.
