Enlarged perivascular space burden associations with arterial stiffness and cognition

Neurobiology of Aging, 2023
Enlarged perivascular spaces (ePVS) are difficult to quantify, and their etiologies and consequences are poorly understood. Vanderbilt Memory and Aging Project participants (n = 327, 73 ± 7 years) completed 3T brain MRI to quantify ePVS volume and count, longitudinal neuropsychological assessment, and cardiac MRI to quantify aortic stiffness.

Enlarging and shrinking focal perivascular spaces

The Neuroradiology Journal
Background and Purpose Perivascular spaces (PVS) are interstitial fluid-filled spaces surrounding blood vessels traversing the deep gray nuclei and white matter of the brain. These are commonly encountered on CT and MR imaging and are generally asymptomatic and of no clinical significance.

Physiology and Clinical Relevance of Enlarged Perivascular Spaces in the Aging Brain

Neurology, 2022
Perivascular spaces (PVS) are fluid-filled compartments that are part of the cerebral blood vessel wall and represent the conduit for fluid transport in and out of the brain. PVS are considered pathologic when sufficiently enlarged to be visible on MRI.

Surgery for enlarged perivascular spaces: primary experience

Burdenko's Journal of Neurosurgery
Perivascular spaces are cavities surrounding cerebral and spinal cord vessels and filled with cerebrospinal or intercellular fluid. Abnormal enlargement of these spaces can lead to neurological symptoms. Currently, there are no clear approaches to surgical treatment of this pathology.

Enlarged perivascular spaces and florbetapir uptake in patients with intracerebral hemorrhage

European Journal of Nuclear Medicine and Molecular Imaging, 2019
Enlarged perivascular spaces in the centrum semiovale (CSO-EPVS) have been linked to cerebral amyloid angiopathy (CAA). To get insight into the underlying mechanisms of this association, we investigated the relationship between amyloid-β deposition assessed by 18F-florbetapir PET and CSO-EPVS in patients with acute intracerebral hemorrhage (ICH).We ...

Cerebrovascular Infarction: Enlarged Perivascular Spaces

2018
In November 2011, a 64-year-old male patient was referred from his neurologist, as an out-hospital patient, to perform MRI of the brain, due to general weakness with nausea lasting for a year on a daily basis. He worked as a captain of merchant overseas ships and, back then he was retired for a year, had a mild arterial hypertension in anamnesis (Fig ...

Enlarged Perivascular Spaces in Patients with Lacunar Infarctions

Current Neurovascular Research
Introduction: Lacunar infarction (LI) and enlarged perivascular spaces (EPVSs) are key MRI findings in cerebral small vessel disease. The underlying causes of LI and EPVS share similarities. To explore their relationship, we examined the association between lacunar infarction (LI) and enlarged perivascular ...

Enlarged perivascular spaces in the basal ganglia across epilepsy subtypes

Epilepsia
Abstract Objective The glymphatic system is thought to be the brain's primary waste clearance system, responsible for eliminating soluble metabolites and proteins from the central nervous system.
