Perivascular spaces, glymphatic dysfunction, and small vessel disease [PDF]

, 2017
Cerebral small vessel diseases (SVDs) range broadly in etiology but share remarkably overlapping pathology. Features of SVD including enlarged perivascular spaces (EPVS) and formation of abluminal protein deposits cannot be completely explained by the ...

Enlarged Perivascular Spaces and Cerebral Small Vessel Disease in Spontaneous Intracerebral Hemorrhage Patients

Frontiers in Neurology, 2019
Background: Cerebral small vessel disease (SVD) is associated with cognitive decline, depression, increased mortality, and disability in stroke patients. MRI-visible perivascular spaces (PVS) are a sensitive neuroimaging marker of SVD.

Perivascular space enlargement and cerebrovascular and Alzheimer’s diseases

Alzheimer's & Dementia
AbstractBackgroundPerivascular spaces (PVS) can become large enough to be visible in magnetic resonance imaging (MRI). The exact aetiology of PVS enlargement in humans remains, however, elusive and under continuous debate [1‐5]. Here, we tracked PVS volumes longitudinally over three years in 525 individuals along AD syndromal cognitive stages, namely ...

Leveraging Ellipsoid Bounding Shapes and Fast R-CNN for Enlarged Perivascular Spaces Detection and Segmentation [PDF]

Enlarged perivascular spaces (EPVS) are small fluid-filled spaces surrounding blood vessels in the brain. They have been found to be important in the development and progression of cerebrovascular disease, including stroke, dementia, and cerebral small ...

The Significance and Mechanism of Cerebral Enlarged Perivascular Space in Amyotrophic Lateral Sclerosis [PDF]

Enlarged perivascular spaces (EPVS) are MRI markers of impaired glymphatic clearance and have been associated with neurodegenerative diseases. However, their clinical significance in amyotrophic lateral sclerosis (ALS) and underlying mechanisms remain ...

Stimulant and opioid dependence effects on enlarged perivascular spaces in a marginalized population [PDF]

, 2022
Enlarged perivascular spaces (EPVS) are markers of cerebral small vessel (CSVD) disease, the most common cause of vascular dementia. Risk factors of EPVS are age, hypertension, lacunes, and microbleeds. Although the etiology of EPVS is unclear, these
