Conversion disorder is a neurological/psychiatric disorder. It is one of a group of psychological disorders called somatoform disorders.

If underlying anxiety or depression is also occurring, medications may be used to help treat those conditions.
It is important to be consistent with treatment to help prevent a recurrence of the disorder.
