Corral's article is about reveling in the memories with the patient. A nurse that she interviewed says: "'[Experts] saw that to try to repeat what was really happening for that patient for that loved one was only frustrating for both parties. Nothing was accomplished. You can't fix the memory loss, the disorientation or the hallucination, so it's kind of let's use what's going on with them to their benefit'" (Corral). Personally, I noticed that when we visited my grandmother and went along with her strange stories or retold a memory all of us were a lot happier, especially my grandmother. It's hard to see someone you love deteriorate in front of your eyes and not be able to help them, but being able to have pleasant, though strange, conversations and create more good memories with them is such a reprieve. It's a "pleasant distraction" for the patient, the caregiver, and the family/loved ones.
(kind of cheesy but the tips apply to what Corral's article talks about)
I think Rene Descartes would agree with this idea of dealing with Alzheimer's: "It is not necessary that I should show that all of these are false - I shall perhaps never arrive at this end" (Descartes 17). Descartes believed that if you can justify your reality and it seems right to you, than it's "real". Therefore, people who suffer from Alzheimer's have their reality replaced with their memories and hallucinations and are not necessarily aware of this shift after it has happened (though, going through the change must be scary as hell). When they are told that what they think is real isn't, they get really upset and confused. Imagine someone telling you that your reality isn't "real" and see how you'll feel and react. Descartes' major tag line is "I think therefore I am", something that can also be applied to Alzheimer's patients. If the patient is in a memory or hallucination in which they are a child, when in fact they are actually 89, their reality has become them being a child and not an 89 year old person. These patients are not just remembering things from the past, they are living in them.
