Acute ischemic stroke secondary to ventriculoperitoneal shunt dysfunction in a child with Moyamoya syndrome
CONCLUSION: Children who receive RT for brain tumor, particularly if the circle of Willis region is involved, require close surveillance for the development of vasculopathy and consequent stroke. This surveillance must be even tighter if the patient has been treated with ventricular shunt for the possible synergistic interaction between the two causes on reducing cerebral perfusion and increasing the risk of acute ischemic events.PMID:35928308 | PMC:PMC9345112 | DOI:10.25259/SNI_434_2022

Is it Bell's palsy or a stroke? Emergency physicians have the answer
(American College of Emergency Physicians) Emergency physicians correctly identified nearly 100 percent of patients with Bell's palsy, the symptoms of which are nearly identical to potentially life-threatening diseases such as stroke and brain tumors. The results of a study of six years of California patient records were published online yesterday in Annals of Emergency Medicine.

The Brain Relaxation and Cerebral Metabolism in Stroke Volume Variation–directed Fluid Therapy During Supratentorial Tumors Resection: Crystalloid Solution Versus Colloid Solution
Background:Compared with goal-directed crystalloid therapy, goal-directed colloid therapy during high-risk surgery may improve postoperative outcome. Whether intraoperative fluid therapy based on goal-directed protocol with different types of fluid has distinctive effects on brain relaxation and cerebral metabolism during craniotomy remains unclear. Methods:Forty patients with supratentorial brain tumors undergoing craniotomy were randomly assigned to either a Ringer’s Lactate-based goal-directed group (LR group, n=20) or a 6% hydroxyethyl starch–based goal-directed group (HES group, n=20). The goal was achieved by mai...

Stroke victim has forehead muscles transplanted into her cheek so she can smile
Sara McKay, 45, from Consett in County Durham says her army husband George, 43, has been her 'lifeline' after having to re-learn to walk and talk due to a paralysing stroke and brain tumour.

The blood-brain barrier–Gatekeeper to neuronal homeostasis: Clinical implications in the setting of stroke
Publication date: Available online 7 November 2014 Source:Seminars in Cell & Developmental Biology Author(s): Karl Schoknecht , Yaron David , Uwe Heinemann The blood-brain barrier is part of the neurovascular unit and serves as a functional and anatomical barrier between the blood and the extracellular space. It controls the flow of solutes in and out of the brain thereby providing an optimal environment for neuronal functioning. Paracellular transport between endothelial cells is restricted by tight junctions and transendothelial transport is reduced and more selective compared to capillaries of other organs. Fu...

The subpopulation of microglia expressing functional muscarinic acetylcholine receptors expands in stroke and Alzheimer’s disease
Abstract Microglia undergo a process of activation in pathology which is controlled by many factors including neurotransmitters. We found that a subpopulation (11 %) of freshly isolated adult microglia respond to the muscarinic acetylcholine receptor agonist carbachol with a Ca2+ increase and a subpopulation of similar size (16 %) was observed by FACS analysis using an antibody against the M3 receptor subtype. The carbachol-sensitive population increased in microglia/brain macrophages isolated from tissue of mouse models for stroke (60 %) and Alzheimer’s disease (25 %), but not for glioma and multiple sclero...

Intratumoral Hemorrhage in a Patient with Malignant Meningioma under Anticoagulant Therapy
We report the case of an elderly woman with malignant meningioma and atrial fibrillation who started taking anticoagulants after an ischemic stroke and subsequently developed intratumoral hemorrhage. Further studies are required to confirm whether a particular anticoagulant agent is suitable for patients with brain tumor and atrial fibrillation.

Functional Gain after Rehabilitation Program in Patients with Brain Tumor and Stroke
To investigate functional gains in brain tumors (BT) survivors after an interdisciplinary rehabilitation program (IRP) and compare with gains made by stroke survivors. Hypothesis: both populations could achieve similar functional gains.

Brain networks under attack: robustness properties and the impact of lesions
A growing number of studies approach the brain as a complex network, the so-called ‘connectome’. Adopting this framework, we examine what types or extent of damage the brain can withstand—referred to as network ‘robustness’—and conversely, which kind of distortions can be expected after brain lesions. To this end, we review computational lesion studies and empirical studies investigating network alterations in brain tumour, stroke and traumatic brain injury patients. Common to these three types of focal injury is that there is no unequivocal relationship between the anatomical lesion sit...
