The potential role of sleep quality in the relationship between glymphatic function and migraine frequency: Insights from a cross‐sectional study

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study aimed to explore the association between glymphatic function, as assessed by the diffusion tensor imaging along perivascular space (DTI‐ALPS) index, and headache frequency in individuals with migraine. Additionally, it evaluated whether sleep quality modulates this relationship.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Feasibility of superimposed supine cycling and lower body negative pressure as an effective means of prolonging exercise tolerance in individuals experiencing persisting post‐concussive symptoms: Preliminary results

Experimental Physiology, EarlyView.
Abstract To examine the feasibility, utility and safety of superimposed lower body negative pressure (LBNP) and tilt during supine cycling in individuals suffering from persisting post‐concussive symptoms (PPCS). Eleven individuals aged 17–31 (6 females/5 males) participated in two randomized separate visits, 1 week apart.

Effects of the angle of head‐down tilt on dynamic cerebral autoregulation during combined exposure to cephalad fluid shift and mild hypercapnia

Experimental Physiology, EarlyView.
Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

The effect of combined treatment with transcranial direct current stimulation on cerebral blood flow in patients with cerebral palsy

Zaporožskij Medicinskij Žurnal, 2017
There is a close link between the activity of the brain and cerebral blood supply. Transcranial direct current stimulation (tDCS) modulates the activity of the cerebral cortex and thus affects the cerebral blood flow.

Image Guidance for Transcranial Doppler Ultrasonography

Operative Neurosurgery, 2011
Transcranial Doppler (TCD) ultrasonography is an important tool for noninvasive detection and monitoring of vasospasm and other pathological conditions of the intracranial vessels.To demonstrate that image-guided TCD allows rapid identification and blood-flow analysis of specific sections of the vascular anatomy and provides excellent orientation, also

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Transcranial Doppler ultrasonography to evaluate cerebral hemodynamic changes in neurocysticercosis

Arquivos de Neuro-Psiquiatria
Background Arteritis is a complication of neurocysticercosis (NCC), which is not well known and could trigger strokes. The transcranial Doppler ultrasound (TCD) is a noninvasive method for detecting, staging, and monitoring cerebrovascular ...

Assessment of the risk of stroke in children with sickle cell anemia using transcranial doppler ultrasound with imaging in Northwestern Nigeria

Nigerian Journal of Paediatrics, 2023
Background: Stroke is a major cause of morbidity and mortality affecting about 10% of patients with sickle cell anemia (SCA). Transcranial Doppler (TCD) ultrasonography helps to identify children with SCA who are at an increased risk for stroke.
