Looking at the Causes of Dissociative Identity Disorder
According to the National Library of Medicine, dissociative identity disorder affects an estimated 1.5% of the general population. The exact causes of DID are not fully understood, but the condition is believed to be related to a combination of genetic, biological, psychological, and social factors.
Experiencing significant childhood trauma, such as physical, sexual, or emotional abuse, is considered a major risk factor for developing DID. The dissociation that occurs in DID is thought to be the mind's way of coping with overwhelming traumatic experiences. Other factors that may contribute to the development of DID include neurobiological factors, attachment difficulties in childhood, and sociocultural influences. For example, researchers have found that certain regions of the brain, such as the hippocampus and amygdala, function differently in people with DID compared to those without the condition.
