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.

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.

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.

Two decades of astrocytes in neurovascular coupling

Frontiers in Network Physiology, 2023
The brain is a highly energy demanding organ, which accounts in humans for the 20% of total energy consumption at resting state although comprising only 2% of the body mass. The necessary delivery of nutrients to brain parenchyma is ensured by the cerebral circulatory system, through the exchange of glucose and oxygen (O2) at the capillary level ...

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 ...

Neurovascular Coupling in Pregnancy and the Risk of Preeclampsia [PDF]

Stroke, 2014
Background and Purpose— This study investigated whether a short testing of neurovascular coupling during midterm pregnancy could identify women at risk for subsequent preeclampsia. Methods— Transcranial Doppler sonography of the posterior cerebral artery during a brief visual ...

Integrative neurovascular coupling and neurotransmitter analyses in anisometropic and visual deprivation amblyopia children

iScience
Summary: The association between visual abnormalities and impairments in cerebral blood flow and brain region potentially results in neural dysfunction of amblyopia. Nevertheless, the differences in the complex mechanisms of brain neural network coupling
