Association between Perivascular Spaces and Progression of White Matter Hyperintensities in Lacunar Stroke Patients. [PDF]

PLoS ONE, 2015
Perivascular spaces are associated with MRI markers of cerebral small vessel disease, including white matter hyperintensities. Although perivascular spaces are considered to be an early MRI marker of cerebral small vessel disease, it is unknown whether ...

Giant expanded perivascular spaces: literature review and description of a clinical case [PDF]

Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2021
The differentiation of giant perivascular spaces is the complicated task due to its rare occurrence and multiple differential series. Cystic neoplasms, parasitic cysts, and lacunar strokes are need to be excluded.

Brain Enlarged Perivascular Spaces as Imaging Biomarkers of Cerebrovascular Disease: A Clinical Narrative Review

Journal of the American Heart Association, 2022
: Perivascular spaces or Virchow‐Robin spaces form pathways along the subarachnoid spaces that facilitate the effective clearance of brain metabolic by‐products through intracellular exchange and drainage of cerebrospinal fluid.

Association of Apolipoprotein E ɛ4 allele with Enlarged Perivascular Spaces [PDF]

Annals of Neurology, 2022
Enlarged perivascular spaces have emerged as markers of cerebral small vessel disease and are linked to perivascular drainage dysfunction. The apolipoprotein E‐ɛ4 (APOE‐ɛ4) allele is the strongest genetic risk factor for cerebral amyloid angiopathy and ...

“Mind the Gap”—enlarged perivascular spaces as a potential magnetic resonance imaging biomarker of impaired glymphatic clearance in brain disorders [PDF]

Frontiers in Cellular Neuroscience
The abundant capillary network penetrating the brain parenchyma is surrounded by potential tubular, fluid-filled regions referred to as perivascular spaces (PVSs).

Perivascular Spaces and the Two Steps to Neuroinflammation [PDF]

Journal of Neuropathology & Experimental Neurology, 2008
Immune cells enter the central nervous system (CNS) from the circulation under normal conditions for immunosurveillance and in inflammatory neurologic diseases. This review describes the distinct anatomic features of the CNS vasculature that permit it to maintain parenchymal homeostasis and which necessitate specific mechanisms for neuroinflammation to

Perivascular Spaces, Diffusivity Along Perivascular Spaces, and Free Water in Cerebral Small Vessel Disease

Neurology
Previous studies have linked the MRI measures of perivascular spaces (PVSs), diffusivity along the perivascular spaces (DTI-ALPS), and free water (FW) to cerebral small vessel disease (SVD) and SVD-related cognitive impairments. However, studies on the longitudinal associations between the three MRI measures, SVD progression, and cognitive decline are ...
