In the film "The Notebook" the main character Allie ends up with Alzheimer's as she gets older. Alzheimer's disease, is one form of dementia that gradually gets worse over time. It affects memory, thinking, and behavior. It happens because the brain stops working. In a modern-day nursing home, an elderly man begins to read a love story from his notebook to a female fellow patient. He is telling the love story of Allie and Noah. As the story unfolds and comes to a conclusion the old woman begins to remember that the love story is about her and her husband, the man reading the story. As the viewer, we learn that Allie wrote this story when she learned she had Alzheimer's and gave it to Noah to read to her so she would remember her life and their love.
The doctor in the movie tells Noah that there is no hope for Allie and that she won't remember him and their life together because she has a more serious case. Noah knows that she will remember if he continues to read to her everyday. When Allie does remember that the story is about them she only remembers Noah and there life together for about 5 minutes before she relapses and doesn't know what is going on. When Noah sees her relapse it crushes him because he wants so badly for her to remember for a long time period and for things to go back to the way they were.
This movie besides being one of the greatest love stories of all time is a great example of how loved one's deal with Alzhemier's. It has to be so hard to watch the one you love slowly losing their memory and not even knowing that they are married and what happened in their past. Noah perseveres and doesn't give up hope on Allie which is all that she can unknowingly ask for.
