概括

与对照组相比,偏头痛患者的白质损伤增加,以更高的骨平均扩散度 (PSMD) 的峰值宽度表示. 这表明偏头痛与小血管疾病 (SVD) 有联系.

科学领域:

神经学
放射学
神经成像

背景情况:

偏头痛是一种常见的神经疾病,
小血管疾病 (SVD) 是老年人白质损伤的主要原因.
扩散张力成像 (DTI) 评估白质完整性.

研究的目的:

使用PSMD调查偏头痛和SVD之间的关系.
评估PSMD作为偏头痛患者白质损伤的标志物.

主要方法:

在73名偏头痛患者和73名健康对照人群中进行了脑部DTI.
计算了骨架平均扩散率 (PSMD) 的峰值宽度.
分析了PSMD和偏头痛特征之间的相关性.

主要成果:

偏头痛患者的PSMD显著高于对照组 (p=0. 027),表明与SVD相关的白质损伤增加.
没有观察到性别或带有/ 没有光环的偏头痛亚型之间的显著PSMD差异.
在男性偏头痛患者中发现了PSMD和疾病持续时间之间的正相关性 (r=0. 601, p=0. 006).

结论:

偏头痛可能与SVD相关.
PSMD是一种有前途的MRI标志物,用于评估头痛疾病中的白质损伤.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
