Impaired Dynamic Cerebral Autoregulation at Extreme High Altitude Even after Acclimatization

, 2010
Cerebral blood flow (CBF) increases and dynamic cerebral autoregulation is impaired by acute hypoxia. We hypothesized that progressive hypocapnia with restoration of arterial oxygen content after altitude acclimatization would normalize CBF and dynamic ...

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, Volume 111, Issue 9, Page 4235-4247, 1 September 2026.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Heart failure‐induced reprogramming of salt‐evoked neurovascular coupling in the rat hypothalamus

The Journal of Physiology, Volume 604, Issue 18, Page 7845-7868, 15 September 2026.
Abstract figure legend In sham rat, hypertonic saline induces activation of the AVP neurons, leading to dendritic AVP release and subsequent V1aR‐mediated PA vasoconstriction resulting in local tissue hypoxia in the SON. In heart failure rat, hypertonic saline similarly induces activation of the AVP neuron leading to dendritic AVP release.

Dynamic cerebral autoregulation assessed by respiratory manoeuvres in non-insulin-treated Type 2 diabetes mellitus

, 2012
Aims This study investigated dynamic cerebral autoregulation in Type 2 diabetes, where dynamic cerebral autoregulation may be impaired as a consequence of microvascular changes and/or autonomic neuropathy.
