血管性帕金森综合征与帕金森病的临床特征及脑白质高信号差异性研究 Differences between Clinical Features and White Matter Hyperintensities between Vascular Parkinsonism and Parkinson′s Disease

Zhongguo cuzhong zazhi, 2023
目的 研究血管性帕金森综合征（vascular parkinsonism，VP）与帕金森病（Parkinson’s disease，PD）临床特征及脑白质高信号（white matter hyperintensities，WMH）的差异，为研究VP的发病机制提供一定的依据与思路。 方法 根据临床实际，健康受试者人数以1∶2的比例匹配，回顾性筛选符合入排标准的VP患者和年龄、性别、受教育程度与其相匹配的PD患者、健康志愿者，健康志愿者作为健康对照（healthy control，HC）组 ...

White matter hyperintensities and smaller cortical thickness are associated with neuropsychiatric symptoms in neurodegenerative and cerebrovascular diseases

Alzheimer’s Research & Therapy, 2023
Background Neuropsychiatric symptoms (NPS) are a core feature of most neurodegenerative and cerebrovascular diseases. White matter hyperintensities and brain atrophy have been implicated in NPS.

Menopausal hot flashes and white matter hyperintensities [PDF]

Menopause, 2016
Hot flashes are classic symptoms of menopause. Emerging data link hot flashes to cardiovascular disease (CVD) risk, yet whether hot flashes are related to brain health is poorly understood. We examined the relationship between hot flashes (measured via physiologic monitor and self-report) and white matter hyperintensities (WMH) among midlife women ...

Semisupervised white matter hyperintensities segmentation on MRI

Human Brain Mapping, 2022
AbstractThis study proposed a semisupervised loss function named level‐set loss (LSLoss) for cerebral white matter hyperintensities (WMHs) segmentation on fluid‐attenuated inversion recovery images. The training procedure did not require manually labeled WMH masks.

Periventricular White Matter Hyperintensities and Functional Decline [PDF]

Journal of the American Geriatrics Society, 2017
Background/Objectives We previously showed that global brain white matter hyperintensity volume ( WMHV ) was associated with accelerated long‐term functional decline. The objective of the current study was to determine whether
