OBJECTIVES: To review the current state of cerebral stimulation for neuropathic pain and to propose that cerebral stimulation should aim also at the affective sphere of chronic pain rather than solely focusing on the primary sensory-discriminative sphere. METHODS: The past and current goals of cerebral stimulation are reviewed as well as its limitations. A novel deep brain stimulation approach is proposed to evaluate this conceptual shift from somatosensory to affective sphere of pain targeting. APPROACH: Thalamic and other central pain syndromes are typically intractable to current treatment methods, including cerebral neuromodulation of somatosensory pathways, leading to long-term distress and disability. Our modern understanding of chronic pain pathophysiology is based largely on the neuromatrix theory, where cognitive, affective, and sensory-discriminative spheres contribute equally to the overall pain experience. During the last decade, the safety and feasibility of chronic stimulation of neural pathways related to mood and affect has been explored with promising results. Here, we propose a novel approach to modulate the affective sphere of chronic pain by targeting similar networks in patients with treatment-refractory central pain. Our primary goal is not to produce (or measure) analgesia, but rather to modulate the affective burden of chronic pain. DISCUSSION: Cerebral neuromodulation for neuropathic pain has had limited efficacy thus far. Shifting our aim to neural networks related to the affective sphere of pain may allow us to reduce pain conditioning and pain-related disability. Our ultimate goal is to promote rehabilitation from chronic pain-social and occupational.
目的:回顾目前用于治疗神经性疼痛的大脑刺激技术,并提出大脑刺激应该针对慢性疼痛的情感领域,而不仅仅关注于主要的感觉-辨别领域。
方法:回顾大脑刺激的过去和当前目标及其局限性。提出了一种新的深部脑刺激方法,以评估从躯体感觉向疼痛靶向的情感领域的这种概念转变。
方法:丘脑和其他中枢性疼痛综合征通常对目前的治疗方法(包括躯体感觉通路的大脑神经调节)没有反应,导致长期的痛苦和残疾。我们对慢性疼痛病理生理学的现代理解主要基于神经基质理论,其中认知、情感和感觉辨别领域对整体疼痛体验同样重要。在过去的十年中,已经探索了通过靶向与情绪和情感相关的神经通路进行慢性刺激的安全性和可行性,并取得了有希望的结果。在这里,我们提出了一种通过靶向治疗抵抗性中枢性疼痛患者的类似网络来调节慢性疼痛的情感领域的新方法。我们的主要目标不是产生(或测量)镇痛,而是调节慢性疼痛的情感负担。
讨论:到目前为止,用于治疗神经性疼痛的大脑神经调节的效果有限。将我们的目标转移到与疼痛的情感领域相关的神经网络上,可能使我们能够减少疼痛条件反射和与疼痛相关的残疾。我们的最终目标是促进慢性疼痛的康复——社交和职业。
