Abstract

OBJECTIVE:

The purpose of this study was to determine whether or not conversion symptoms are lateralized. Studies have shown a predominant left-oriented manifestation of symptoms for most somatoform disorders. The reports in the literature on the lateralization of conversion symptoms, however, are rather conflicting. They show left-sided, right-sided, or no symptom lateralization in conversion disorders.

METHODS:

One hundred fourteen patients with conversion disorder were screened for symptom lateralization.

RESULTS:

Those patients with unilateral symptoms (32.5%) showed no significant bias toward left or right symptom presentation.

CONCLUSION:

Based on these results, and the conflicting findings from previous studies, we conclude that there is insufficient support for lateralization theories in conversion disorder.
