Conversion Disorder

Before neurological evaluation rules out physical causes this Somatoform Disorder can be confused with a physical illness that affects sensory (e.g. anesthesia, blindness) or voluntary motor functioning (e.g. astasia-abasia, paralysis). Usually the deficit fails to conform to known anatomical or physiological characteristics.

Diagnostic criteria for 300.11 Conversion Disorder
