The Notebook is one of my favorite movies of all time; of course it is a love story and captures thousand of hearts. The interesting thing about this movie is it ties into psychology. Psychology is around us all the time. One of the main parts of the movie is how Allie is suffering from dementia at an older age and she can't remember whom Noah, her children, or her grandchildren are. She is suffering from severe memory loss and throughout the whole movie Noah tells Allie the story of her life, and he thinks she will begin to remember again. At one point in the story Allie remembers who Noah is, and it is such a sad but wonderful part, she can only remember who he is for a moment though, before she relapsed.
Dementia is a chronic brain syndrome that affects many older people. Dementia is a loss of brain function and it affects the memory, thinking, language, judgment, and behavior. Alzheimer's Disease and dementia are very similar but dementia is just a syndrome and Alzheimer's disease is the actual illness. Allie probably suffered from Alzheimer's disease. Many types of dementia are nonreversible, so the patient would never get their memory back. In some cases, like Allies, it does come back for small instances. Allie's hippocampus was being damaged because that is where memory is located in the brain.
I think it is really amazing how Noah held on to Allie even though she did not even know who he was. In the end of the movie Allie remembered who Noah was and true love conquered all.
