TREATMENT OF COGNITIVE IMPAIRMENT AFTER STROKE

Медицинский совет, 2018
The paper presents case report of mild cognitive impairment developed after lacunar infarct of thalamus due to arterial hypertension. Differential diagnosis of post-stroke cognitive impairment and clinical features of cerebral vascular and ...

Extracranial versus intracranial hydro-hemodynamics during aging: a PC-MRI pilot cross-sectional study

Fluids and Barriers of the CNS, 2020
Background Both aging and changes in blood flow velocity between the extracranial (intraspinal) and intracranial regions of cerebral vessels have an impact on brain hydro-hemodynamics.

The effects of hemodynamic lag on functional connectivity and behavior after stroke [PDF]

, 2015
Stroke disrupts the brain's vascular supply, not only within but also outside areas of infarction. We investigated temporal delays (lag) in resting state functional magnetic resonance imaging signals in 130 stroke patients scanned two weeks, three months

Imaging-validated correlates and implications of the pathophysiologic mechanisms of ageing-related cerebral large artery and small vessel diseases: a systematic review and meta-analysis

Behavioral and Brain Functions
Background Cerebral large artery and small vessel diseases are considered substrates of neurological disorders. We explored how the mechanisms of neurovascular uncoupling, dysfunctional blood–brain-barrier (BBB), compromised glymphatic pathway, and ...

The glymphatic system and cerebral small vessel disease.

Journal of Stroke & Cerebrovascular Diseases
OBJECTIVES Cerebral small vessel disease is a group of pathologies in which alterations of the brain's blood vessels contribute to stroke and neurocognitive changes.

Homocysteine in cerebrovascular disease: An independent risk factor for subcortical vascular encephalopathy [PDF]

, 2001
Hyperhomocysteinemia is a risk factor for obstructive large-vessel disease. Here, we studied plasma concentrations of homocysteine and vitamins in patients suffering from subcortical vascular encephalopathy (SVE), a cerebral small-vessel disease leading ...

Dual control of vascular tone and remodelling by ATP released from nerves and endothelial cells [PDF]

, 2008
Purinergic signalling is important both in short-term control of vascular tone and in longer-term control of cell proliferation, migration and death involved in vascular remodelling.

Anterior cerebral artery velocity changes in disease of the middle cerebral artery stem. [PDF]

Stroke, 1989
Transcranial Doppler ultrasonography can map the changes in blood velocity that result from stenosis or occlusion of the middle cerebral artery. To evaluate patterns of collateral blood flow in disease of the middle cerebral artery stem, we used both cerebral angiography and transcranial Doppler ultrasonography to study the systolic blood velocities in
