My mil had been diagnosed with PSP which is a rare disease that is very similar to Parkinson's, except that instead of shaking, she froze... and would fall...a LOT. My fil was her main caregiver with my sil filling in the gaps. We had been abroad and were not fully apprised of the situation.
Having recently returned to the UK, we were trying to catch our breath completely unaware of what was unfolding in regards to my mil's care. Fair enough... we hadn't been there!
My fil had a long awaited and very much deserved holiday planned for two weeks away. She had gotten to the point where it was far too dangerous to leave her alone. My sil was working and simply not able to do the full time care required. They had been looking at care homes for about 6 months, knowing that the trip was coming, but also with an eye to the not too distant future where she would need full time professional care that my aging file would not be able to manage on his own.
They settled on a very very very nice care facility. It was quite a distance from her home so daily visits from friends and family would be impossible to manage, but it was the nicest one they had seen. There was the hair stylist and the outings and the events and the nice restaurant!
But, it wasn't long into the stay that the reality hit. She had lost her ability to speak and as she drooled uncontrollably, she was too embarrassed to be with strangers. Also, she wasn't good at asking for help which resulted in quite a few falls in her first days. She hadn't been entirely forthcoming with her difficulties. In addition, because of her speech issues, the carers didn't always understand what she wanted. To be fair she was very confusing in her attempts to communicate. If someone asked a question, she might shake her head no, but then attempt to explain what she did want... Which was likely what had been proposed. She was embarrassed by her eating challenges so never went to the restaurant. Or the outings or the daily activities. She stopped eating and quickly lost weight because she didn't like the food.
We had decided to come and visit after talking to her on the phone and finally understanding the gravity of the situation. My husband asked her if she wanted to go home and she did. We set about looking after her.
What started out as a stop gap respite situation, quickly revealed that we were desperately needed. We took over her full time care. I managed her medical needs, which came to involve a stomach tube. My husband managed keeping her as fit as she could be and helping her move from room to room. The whole family became a great team. Everyone worked together.
I soon realized that I could do really hard things. I had never considered myself the type of person that could be a carer for someone else. Neither did I know that when it came down to it, I was able to administer CPR on two different occasions.
We cared for her until her passing 2 and a half years after we arrived. Her original prognosis after diagnosis was 5-7 years... She lived 14!! The doctors were stunned. The day prior to her passing, her friends and grandchildren had been over for a visit. She had been on the cross trainer ( she was so fit for being so ill! We supervised her for safety, but her keeping moving was critical to her longevity) and seemed at peace.
My only advice is that everyone is different and it is important to consider the full context of the situation and all concerned. We were able and willing to move in and take over care. But not all can. And not all people want to be cared for by family.
