Summary: Studies have shown evidence of asymmetry in the response of cerebral autoregulation (CA) to increasing and decreasing pressure challenges. CA appears to be stronger during transient increases in arterial blood pressure and weaker during decreases. The measurement of this effect and its relevance in clinical settings remain questionable.

Summary: This study compared cerebral autoregulation in all major cerebral vessels and found that while the time course of autoregulation was similar in all vessels, the magnitude of hemodynamic regulation was lower in the posterior cerebral artery. However, after adjusting for baseline flow differences, normalized gain was similar in all vessels.

Summary: This study aimed to investigate the effects of age and sex on neurovascular coupling (NVC). The results showed a negative relationship between NVC and age in females, while no relationship was found in males. These findings highlight the importance of considering sex-dependent effects of aging when studying cerebrovascular regulation.

Summary: This study aims to quantify the agreement between left and right middle cerebral artery blood velocity (MCAv) responses to incremental and constant work-rate exercise in adults. The results showed similarities between left and right MCAv responses to incremental and constant work-rate exercise in adults on a group-level, but also highlighted individual variation in the agreement between left and right MCAv exercise responses.

Summary: Cerebral autoregulation is the process by which cerebral blood flow remains constant in response to short-term variations in arterial blood pressure. Recent studies challenge the classic view that autoregulation remains constant over a wide range of blood pressure. A comprehensive literature research based on 143 studies found that there is a significant difference in the direction of blood flow sensitivity, with autoregulation being more effective in buffering increases in blood pressure. Regression analysis identified an autoregulatory plateau of approximately 20 mmHg, which is smaller than the widely accepted classical view. Age and sex were found to have no effect on autoregulation strength. This data-driven approach provides a quantitative method for analyzing static autoregulation.

Summary: This study found that an increase in velocity in the middle cerebral artery (MCA) was associated with intracranial hypertension in traumatic brain injury (TBI) patients. Transcranial EcoDoppler (TCD) monitoring could be a useful method to detect and guide the therapy for this condition. It may serve as a tool for cause-oriented therapy of intracranial hypertension.

Summary: The study showed that valid and reliable dynamic cerebral autoregulation estimates can be obtained from shorter recording durations of squat-stand maneuvers, such as 180 or 240 seconds, when physiological covariates are controlled. However, future studies should aim for 300-second recordings to ensure optimal results.

Summary: This study assessed cerebral autoregulation during sustained hypotension, revealing its behavior during hypotension. Results showed that CA was disturbed during sustained hypotension but improved after blood pressure restoration, suggesting the absence of ischemic hyperemia and an unlikely adaptation mechanism during sustained hypotension.

Summary: This article discusses the importance of reperfusion treatment in acute ischemic stroke patients and highlights the impact of blood pressure on cerebral perfusion. It emphasizes the importance of effective blood pressure management in the early stages of stroke, and suggests that bedside monitoring of cerebral perfusion and oxygenation can help guide treatment and improve outcomes.

Summary: Dynamic cerebral autoregulation and cerebral perfusion pressure are altered in pregnancies complicated by preeclampsia, which may be important in the pathophysiological pathway and constitute a therapeutic target in the prevention of cerebral complications in preeclampsia.

Summary: The study found that impaired cerebral autoregulation (CA) was present in young adults with mild depression, and was negatively correlated with HAMD scores. The phase difference was identified as a valid indicator for identifying patients with depression, with a cutoff value of 29.66.

Summary: The authors conducted a study on the systemic and cerebral hemodynamics in various neurosurgical pathologies using signal processing methods. Their proposed method based on continuous wavelet transform shows higher sensitivity and better localization compared to traditional methods. This research is important for finding effective treatment solutions for patients with different pathologies.

Summary: This paper reviews the potential impact of common drugs used in acute ischaemic stroke (AIS) management on cerebral haemodynamics, with a focus on cerebral autoregulation (CA). The discussion includes the influence of clot lysis, clot prevention compounds, and antihypertensive medications on cerebral perfusion and CA, emphasizing the relevance of pharmacological agents in modelling cerebral perfusion accuracy and individualized treatment strategies for AIS patients.
