Abstract
Background: Although subjective sensory hypersensitivity is prevalent after stroke, it is rarely recognized by health care providers, and its neural mechanisms are largely unknown.
Objective: To investigate the neuroanatomy of poststroke subjective sensory hypersensitivity as well as the sensory modalities in which subjective sensory hypersensitivity can occur by conducting both a systematic literature review and a multiple case study of patients with subjective sensory hypersensitivity.
Method: For the systematic review, we searched three databases (Web of Science, PubMed, and Scopus) for empirical articles discussing the neuroanatomy of poststroke subjective sensory hypersensitivity in humans. We assessed the methodological quality of the included studies using the case reports critical appraisal tool and summarized the results using a qualitative synthesis. For the multiple case study, we administered a patient-friendly sensory sensitivity questionnaire to three individuals with a subacute right-hemispheric stroke and a matched control group and delineated brain lesions on a clinical brain scan.
Results: Our systematic literature search resulted in four studies (describing eight stroke patients), all of which linked poststroke subjective sensory hypersensitivity to insular lesions. The results of our multiple case study indicated that all three stroke patients reported an atypically high sensitivity to different sensory modalities. These patients' lesions overlapped with the right anterior insula, the claustrum, and the Rolandic operculum.
Conclusion: Both our systematic literature review and our multiple case study provide preliminary evidence for a role of the insula in poststroke subjective sensory hypersensitivity and suggest that poststroke subjective sensory hypersensitivity can occur in different sensory modalities.
背景:尽管主观感觉超敏反应在中风后很普遍,但它很少被卫生保健提供者所认识,其神经机制也在很大程度上不为人知。目的:通过系统的文献回顾和对主观感觉超敏患者的多病例研究,研究脑卒中后主观感觉超敏感的神经解剖学以及主观感觉超敏感性可能发生的感觉模式。方法:为了进行系统综述,我们在三个数据库(Web of Science、PubMed和Scopus)中搜索了讨论人类脑卒中后主观感觉超敏反应神经解剖学的实证文章。我们使用病例报告关键评估工具评估了纳入研究的方法学质量,并使用定性综合总结了结果。在多病例研究中,我们对三名亚急性右半球卒中患者和一个匹配的对照组进行了一份对患者友好的感觉敏感性问卷调查,并在临床脑部扫描中描绘了脑部病变。结果:我们的系统文献检索导致了四项研究(描述了八名中风患者),所有这些研究都将中风后主观感觉超敏反应与岛叶病变联系起来。我们的多病例研究结果表明,所有三名中风患者都报告了对不同感觉模式的异常高敏感性。这些患者的病变与右前脑岛、幽闭和Rolandic盖重叠。结论:我们的系统文献综述和多个病例研究都为脑岛在卒中后主观感觉超敏反应中的作用提供了初步证据,并表明卒中后主观感官超敏反应可能以不同的感觉模式发生。
期刊介绍:
Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement.
The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
