Miguel's wife brought him to the emergency room because Miguel could not remember his name, the names of his family members, whe

Dissociative Disorder, also known as conversion disorder, is a mental disorder in which the person suffers from a psychological imbalance, with alterations in consciousness, memory, identity, emotion, perception of the environment, movement control and behavior.
