Cerebrovascular regulation during heat stress
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Transcranial Doppler in cerebrovascular disease.
Doppler analysis of flow in intracranial arteries is now possible using a 2 MHz probe allowing sufficient penetration of bone to obtain signals noninvasively.

Transcranial doppler for carotid endarterectomy
Patients with symptomatic high-grade carotid artery stenosis benefit from carotid endarterectomy. However, the operation is not without complications. The perioperative stroke rate varies from 2 to as much as 24% and depends on technique and patient selection. Seventy percent of perioperative strokes occur during the operation and are equally caused by

Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Brain strain: Blood flow and metabolism in environmental extremes
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

Intracranial hypertension influence on the cerebral blood flow in children with serous meningitis
Transcranial Doppler sonography was performed in 120 children with serous meningitis with various degrees of intracranial hypertension. Cerebral blood flow disturbances – decreased dilatation reserve and mean blood flow velocity in cerebral arteries ...

Stroke neurovascular responses to exercise: A novel rehabilitation paradigm
Abstract Stroke is a leading cause of long‐term disability, impacting the cerebrovascular, peripheral vascular and neuromotor systems. Characterising vascular responses to exercise post‐stroke offers valuable insights into the impairments that might influence outcomes during neurorehabilitation.

Abstract Acute heat stress reduces cerebral haemodynamics and orthostatic tolerance. However, the haemodynamic response to orthostasis during prolonged heat stress typical of heatwaves is unknown. We hypothesised that thermoregulatory‐induced elevations in peripheral haemodynamics during 3 days of simulated heatwave would exacerbate orthostatic‐induced
