Neurovascular coupling unit dysfunction and dementia: Retinal measurements as tools to move towards population-based evidence

Frontiers in Endocrinology, 2022
Dysfunction of the neurovascular coupling unit may be an important contributor to dementia. The neurovascular coupling unit comprises neuronal structures (e.g. astrocytes) and vascular structures (e.g.

Cerebral Autoregulation and Neurovascular Coupling after Craniospinal Irradiation in Long-Term Survivors of Malignant Pediatric Brain Tumors of the Posterior Fossa.

, 2021
INTRODUCTION  Long-term survivors of craniospinal irradiation have an increased risk for stroke which increases with radiation dose and follow-up time.

Autoregulation of the Human Cerebrovasculature by Neurovascular Coupling [PDF]

, 2013
Functional hyperaemia is an important mechanism by which increased neuronal activity is matched by a rapid and regional increase in blood supply.

Neurovascular Decoupling Is Associated With Lobar Intracerebral Hemorrhages and White Matter Hyperintensities

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Neurovascular coupling is a fundamental aspect of brain function by regulating cerebral blood flow in response to regional neuronal activity.

Altered Neurovascular Coupling in Unilateral Pulsatile Tinnitus

Frontiers in Neuroscience, 2022
ObjectiveAltered cerebral blood flow (CBF) and regional homogeneity (ReHo) have been reported in pulsatile tinnitus (PT) patients. We aimed to explore regional neurovascular coupling changes in PT patients.Materials and MethodsTwenty-four right PT ...

Neurovascular coupling is preserved in chronic stroke recovery after targeted photothrombosis

NeuroImage: Clinical, 2023
Functional neuroimaging, which measures hemodynamic responses to brain activity, has great potential for monitoring recovery in stroke patients and guiding rehabilitation during recovery.

Non-invasive, multimodal analysis of cortical activity, blood volume and neurovascular coupling in infantile spasms using EEG-fNIRS monitoring

NeuroImage: Clinical, 2017
Although infantile spasms can be caused by a variety of etiologies, the clinical features are stereotypical. The neuronal and vascular mechanisms that contribute to the emergence of infantile spasms are not well understood.

Neurovascular Coupling in Type 2 Diabetes With Cognitive Decline. A Narrative Review of Neuroimaging Findings and Their Pathophysiological Implications

Frontiers in Endocrinology, 2022
Type 2 diabetes causes substantial long-term damage in several organs including the brain. Cognitive decline is receiving increased attention as diabetes has been established as an independent risk factor along with the identification of several other ...

Evaluation of neurovascular coupling behaviors for FES-induced wrist movements based on synchronized EEG-fNIRS signals [PDF]

The neuronal activities and cerebral hemodynamic responses are closely linked via the neurovascular coupling (NC) mechanism. This mechanism is strongly associated with the brain state and alters with the pathological conditions such as motor dysfunctions.
