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.
目的
本研究旨在确定转换症状是否存在偏侧化。研究表明，大多数躯体形式障碍的症状主要表现为左侧倾向。然而，文献中关于转换症状偏侧化的报道相当矛盾。它们显示转换障碍中存在左侧、右侧或无症状偏侧化。
方法
对114例转换障碍患者进行症状偏侧化筛查。
结果
那些有单侧症状的患者（32.5%）在症状表现上对左侧或右侧没有明显偏向。
结论
基于这些结果以及先前研究的矛盾发现，我们得出结论，转换障碍的偏侧化理论缺乏足够的支持。
