Many people appreciate a good film and ultimately have the potential to judge the film based on the content and performance it delivered. In some films, the screenwriter chooses to portray one of many psychological disorders. Movie audiences will try to focus on how well the disorder was portrayed and how well the movie portrayed it. Whether the director's intention was to try to expose this psychological disorder to the audience or choose to make a film based on the disorder, some viewers will debate whether the film portrayed the disorder accurately and whether the audience took note of the disorder. . Screenwriters Jonathan Nolan and Christopher Nolan depicted the psychological disorder, anterograde amnesia, in their film “Memento.” Anterograde amnesia (AA) is commonly known as short-term memory loss. It is the inability to form new memories after neurological or psychological trauma to the brain. “Current definitions of anterograde amnesia emphasize the presence of severe and permanent deficits in remembering recent events (typically with poor recognition) that contrast with intact short-term memory, IQ, semantic memory, learning abilities, simple classical conditioning, perceptual learning, and priming” (Aggleton, 2008, p. 1442). Furthermore, according to Aggleton, AA causes the inability to remember autobiographical events (episodic memory). Research shows that damage to the diencephalon or frontal lobe can cause AA. Damage to the diencephalon impairs memory performance because it encodes new experiences for future recall, and damage to the frontal lobe of the brain impairs memory performance because it is involved in regulating access to explicit memory (Mendev 2007).
