Photoplethysmography for Quantitative Assessment of Sympathetic Nerve Activity (SNA) During Cold Stress [PDF]

open access: yes, 2019
The differences in the degree of sympathetic nerve activity (SNA) over cutaneous blood vessels, although known to be more prominent in the periphery than the core vasculature, has not been thoroughly investigated quantitatively.

Dynamic Cerebral Autoregulation Post Endovascular Thrombectomy in Acute Ischemic Stroke

open access: yesBrain Sciences, 2020
The development of the endovascular thrombectomy (EVT) technique has revolutionized acute stroke management for patients with large vessel occlusions (LVOs). The impact of successful recanalization using an EVT on autoregulatory profiles is unknown.

Association between impaired dynamic cerebral autoregulation and BBB disruption in reversible cerebral vasoconstriction syndrome

open access: yesThe Journal of Headache and Pain, 2023
Background Half of the sufferers of reversible cerebral vasoconstriction syndrome (RCVS) exhibit imaging-proven blood-brain barrier disruption. The pathogenesis of blood-brain barrier disruption in RCVS remains unclear and mechanism-specific intervention

Dissociation of Cerebral Blood Flow and Femoral Artery Blood Pressure Pulsatility After Cardiac Arrest and Resuscitation in a Rodent Model: Implications for Neurological Recovery. [PDF]

open access: yes, 2020
Background Impaired neurological function affects 85% to 90% of cardiac arrest (CA) survivors. Pulsatile blood flow may play an important role in neurological recovery after CA.

Impact of impaired cerebral blood flow autoregulation on cognitive impairment

open access: yesFrontiers in Aging, 2022
Although the causes of cognitive impairment are multifactorial, emerging evidence indicates that cerebrovascular dysfunction plays an essential role in dementia.

Comparison of frequency and time domain methods of assessment of cerebral autoregulation in traumatic brain injury. [PDF]

open access: yes, 2014
The impulse response (IR)-based autoregulation index (ARI) allows for continuous monitoring of cerebral autoregulation using spontaneous fluctuations of arterial blood pressure (ABP) and cerebral flow velocity (FV).

Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability

open access: yes, 2012
Although the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its ...
