In the film 50 first dates, Adam Sandler plays a character that meets a girl played by Drew Barrymore named Lucy. In the film Lucy is portrayed to be suffering from anterograde amnesia. The effects of this type of amnesia include the inability to create new memories, while holding on to other long-term memories. The film uses the fact that Lucy suffered terrible brain damage in a car accident a few years back. Brain trauma is a common way that people can be inflicted with anterograde amnesia, and the film effectively portrays this in an accurate fashion.
Although this movie is meant mainly to be a comedy they do a good job of portraying anterograde amnesia pretty accurately. Lucy has as much knowledge of her long-term memory prior to the accident as any person not suffering from amnesia. She remembers all the details of her family, and what she did the day of her accident, but is just not able to recall any recent memories. Throughout the movie Adam Sandler's character Henry tries to help Lucy remember how they met, and that they were currently seeing each other, but never makes any real progress in creating any new memories in Lucy all throughout.
In the movie 50 First Dates Lucy is unable to build any new memories past the day of her accident, and at the end of every day she goes to sleep and wakes up with no knowledge of the previous day, or any day following her accident. This part of the movie is border line inaccurate for the reason that a lot of the people that suffer from anterograde amnesia have trouble remembering what they did even earlier in the day, while Lucy finds no struggle with this, but magically when she goes to sleep all of her memory is lost. Her span of memory is a bit too exact to deem this film entirely correct on how people suffering from anterograde amnesia would carry themselves through a day. A better representation of a daily pattern of someone suffering from anterograde amnesia would be Dory from the film Finding Nemo. Dory continues to forget information she had learned earlier throughout the day, and this more accurately reflects anterograde amnesia, rather than the retaining of memories and information until bedtime.
The film 50 First Dates represents a relatively accurate portrayal of how people with anterograde amnesia are affected. Although there are a few parts of the film that can be pointed out to be a little fictional, for the most part the film reflects the condition quite accurately, especially compared with a lot of the other options for films with people that suffer from amnesia, and more specifically, anterograde amnesia.
