When it comes to movies, I am an Adam Sandler enthusiast. Give me a quote from Adam Sandler I will be able to name the movie instantly. So when I read the chapter on memory impairments, I immediately related it to Adam Sandler's movie, 50 First Dates. Since watching this movie, I have been intrigued with Drew Barrymore's character's memory impairment, "Goldfield Syndrome".
In the movie, Lucy (Barrymore) has Goldfield Syndrome, which they strongly correlate to anterograde amensia. Lucy was in a car accident that damaged her ability to transfer short-term memory to long term memory. As this is true for anterograde amnesia, there were also symptoms in Lucy that did not hold true.
One example, the most obvious example, is that Lucy is unable to store any new memories since she was in the accident. Where the movie goes wrong though, is that she can store memories throughout the day until she goes to sleep. When she wakes up she has no recollection of the day before. Realistically, people with anterograde amnesia can't even store memories for longer than 5 or 10 minutes. Sleeping has no relation with anterograde amnesia.

This clip from YouTube shows Lucy's doctor describing her syndrome to her. He also shows her other people with other impairments such as "Ten Second Tom".
Overall, the Goldfield Syndrome in 50 First Dates in fictional.
Nice identification of ways that the story doesn't match anterograde amnesia.
