Abstract

Background: Cortical lesion subtypes' occurrence and distribution across networks may shed light on cognitive impairment (CI) in multiple sclerosis (MS).

Methods: In 332 people with MS, lesions were classified as intracortical, leukocortical or juxtacortical based on artificially generated double inversion-recovery images.

Results: CI-related leukocortical lesion count increases were greatest within sensorimotor and cognitive networks (p < 0.001). Only intracortical lesion count could distinguish between cognitive groups (p = 0.024). Effect sizes were two- to four-fold larger than differences between MS phenotypes.

Conclusion: In CI-MS, leukocortical lesions predominate, whereas intracortical lesions distinguish cognitive groups. Lesions' grey matter (GM) involvement might be decisive for cognition in MS, surpassing overall disease burden.

多发性硬化症患者认知功能障碍与（并）皮质病变的亚型和位置有关。

背景：皮质病变亚型的发生和在网络中的分布可能会揭示多发性硬化症（MS）的认知障碍（CI）：在332名多发性硬化症患者中，根据人工生成的双反转恢复图像将病变分为皮质内、白皮质或并皮质：在感觉运动网络和认知网络中，CI相关的白皮质病变数量增加最多（p < 0.001）。只有皮层内病变计数能区分认知组（p = 0.024）。效应大小比多发性硬化症表型之间的差异大 2 到 4 倍：结论：在 CI-MS 中，白皮质病变占主导地位，而皮质内病变可区分认知组。病变累及灰质（GM）可能对多发性硬化症患者的认知能力起着决定性作用，其程度超过了整体疾病负担。
