Editor’s Note: This article contains spoilers for the film, Split.
On January 20, Split, a film about three girls attempting to escape from Kevin Wendell Crumb’s 23 split personalities, was released in theaters. In the film, Crumb suffers from dissociative identity disorder (DID). Dissociative identity disorder, commonly known as multiple personality disorder, is a mental illness that creates one or more personalities within one individual. The disorder also pairs with memory loss; therefore, the individual is sometimes incapable of realizing their multiple personalities. Normally, the disorder arises from some form of trauma during childhood.
