Triptans and CGRP blockade - impact on the cranial vasculature [PDF]

, 2017
The trigeminovascular system plays a key role in the pathophysiology of migraine. The activation of the trigeminovascular system causes release of various neurotransmitters and neuropeptides, including serotonin and calcitonin gene-related peptide ...

Imaging Cerebral Arteries Tortuosity and Velocities by Transcranial Doppler Ultrasound Is a Reliable Assessment of Brain Aneurysm in Mouse Models

Stroke: Vascular and Interventional Neurology, 2023
Background During the past few decades, several pathophysiological processes contributing to intracranial aneurysm (IA) rupture have been identified, including irregular IA shape, altered hemodynamic stress within the IA, and vessel wall inflammation ...

What went wrong? The flawed concept of cerebrospinal venous insufficiency [PDF]

, 2013
In 2006, Zamboni reintroduced the concept that chronic impaired venous outflow of the central nervous system is associated with multiple sclerosis (MS), coining the term of chronic cerebrospinal venous insufficiency ('CCSVI'). The diagnosis of 'CCSVI' is

The perfect crime? : CCSVI not leaving a trace in MS [PDF]

, 2011
Background: Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of the central nervous system, believed to be triggered by an autoimmune reaction to myelin.

Transcranial Doppler Ultrasound Velocity Measurements in Children With Sickle Cell Disease in Kenya [PDF]

EJHaem
ABSTRACT Background Sickle cell disease (SCD) is the most common inherited haemoglobinopathy and poses a high public health burden in Sub‐Saharan Africa. Children with sickle cell anaemia are at a highrisk of ischemic stroke, and transcranial Doppler (TCD) ultrasonography helps identify those at highest risk for primary stroke prevention.

Cerebral vasoreactivity in response to a headof-bed position change is altered in patients with moderate and severe obstructive sleep apnea [PDF]

, 2018
Obstructive sleep apnea (OSA) can impair cerebral vasoreactivity and is associated with an increased risk of cerebrovascular disease. Unfortunately, an easy-to-use, non-invasive, portable monitor of cerebral vasoreactivity does not exist. Therefore, we

Vasospasm is a significant factor in cyclosporine-induced neurotoxicity: Case report

BMC Neurology, 2010
Background The aetiology of central nervous system lesions observed in cerebral cyclosporine neurotoxicity remains controversial. Case presentation We report a 48-year-old woman with a non-severe aplastic anaemia who presented with stroke-like episodes ...

Transcranial Doppler. [PDF]

Stroke, 1988
TCD recording of flow velocities in intracranial vessels was first described by Aaslid in 1982. The utility of this instrument becomes more apparent as it is used in different clinical settings and compared with angiographic findings (Figures 1 and 2).
