Abstract:
Conversion disorder is one of the terms used to describe various psychosomatic neurological symptoms that are thought to originate from a psychological conflict. Psychological stressors can usually be identified but appear to be almost similar to the severity of psychological stress in non-psychosomatic neurological disorders. Recent neuroimaging research provides one rather robust finding of increased activation in the anterior cingulate gyrus. This activation has been explained as a reflection of 'active inhibition' or 'self-monitoring' but its meaning in conversion disorder still remains mysterious. In this paper, current theories are re-examined from a neuroanatomical point of view.
