Hysterical aphonia is a condition that affects the voice due to psychological reasons rather than a physical disorder. It is also known as conversion disorder, functional aphonia, and psychogenic voice loss. Other terms used to describe hysterical aphonia include hysterical mutism, emotional aphasia, and functional dysphonia. These synonyms are used because the condition is not caused by any identifiable physical damage. Instead, it is believed to be the result of emotional trauma or stress, leading to an unconscious suppression of the voice. Treatment options include psychotherapy and speech therapy, which focuses on restoring normal speech patterns through behavioral changes.
