OBJECTIVE Childhood anxiety and obsessive-compulsive disorder (OCD) are defined by fear, worry, and uncertainty, but there is also evidence that affected children possess exteroceptive sensory abnormalities. These sensory features may often instigate symptoms and cause significant distress and functional impairment. In addition, a purported class of conditions known as "sensory processing disorders" may significantly overlap with childhood anxiety and OCD, which provides further support for a connection between abnormal sensation and fear-based psychopathology. METHOD The current review was conducted to synthesize and to critically evaluate the existing research on exteroceptive sensory abnormalities in childhood anxiety and OCD. Because of the paucity of research in this area, studies with adult populations were also briefly reviewed. RESULTS The review found significant support for the notion that sensory abnormalities are common in children with anxiety disorders and OCD, but there are significant limitations to research in this area that prevent firm conclusions. CONCLUSION Potential avenues for future research on sensory features of pediatric anxiety and OCD are discussed.

综述：童年期青少年和青少年焦虑症和强迫症的躯体感受性异常：一项重要的综述。

目的儿童期焦虑症和强迫症（OCD）的定义是恐惧，担忧和不确定性，但也有证据表明受影响的儿童患有抽搐性感觉异常。这些感官特征通常会诱发症状并引起严重的困扰和功能障碍。此外，所谓的“感觉过程障碍”可能与儿童的焦虑症和强迫症有明显重叠，这为异常感觉与基于恐惧的心理病理学之间的联系提供了进一步的支持。方法目前的综述是对儿童焦虑症和强迫症中外在感觉异常的综合研究，并对其进行了严格的评估。由于该领域的研究匮乏，因此也对成人人群的研究进行了简要回顾。结果这篇评论为焦虑症和强迫症患儿普遍存在感觉异常这一观点提供了重要支持，但该领域的研究存在重大局限性，无法得出明确的结论。结论讨论了进一步研究小儿焦虑和强迫症的感觉特征的潜在途径。
