E-043 Reversible Cerebral Vasoconstriction Syndrome: Non-invasive Imaging Findings and Angiographic Evaluation
We present indirect findings on non-invasive imaging, such as transient cerebral edema, convexal subarachnoid hemorrhage, intraparenchymal hemorrhage and cerebral. Direct signs of single or multivessel arterial vasoconstriction are seen on CTA, MRA and confirmed on DSA. Reversibility of the vasoconstriction is demonstrated after intra-arterial administration of calcium channel blocker. Conditions such as diffuse atherosclerotic arterial narrowing, vasculitis, posterior reversible encephalopathy, cerebral edema secondary to venous congestion and vasospasm secondary to aneurysmal subarachnoid hemorrhage were among the pathol...

Reversible cerebral vasoconstriction syndrome: A rare pediatric cause of thunderclap headaches.
We report on a case of a 13-year-old boy presenting with acute severe headaches, triggered by physical exertion. His past medical history was uneventful. Moderate headache persisted between exacerbations for 4 weeks. He secondarily presented with signs of intracranial hypertension. Brain magnetic resonance angiography (MRA) revealed multifocal narrowing of the cerebral arteries. A glucocorticoid treatment was started based on the hypothesis of primary angiitis of the CNS. The symptoms rapidly improved, and repeat angiography at 3 months showed no vasoconstriction. Although pediatric cases are rare, RCVS should be considere...

Success of Intravenous Infusion of Verapamil for Refractory Vasospasm in aneurysmal Subarachnoid Hemorrhage (P2.291)
Conclusions:This report indicates that intravenous continuous infusion of verapamil may be used for rescue therapy in transiently responsive cerebral vasospasm to IA verapamil. This therapy did not seem to compromise hemodynamic stability or increase ICP.Disclosure: Dr. Mehta has nothing to disclose. Dr. Kulhari has nothing to disclose. Dr. Z Arango has nothing to disclose. Dr. Suhan has nothing to disclose. Dr. DeCarvalho has nothing to disclose. Dr. Patel has nothing to disclose. Dr. Kirmani has nothing to disclose.

Device that measures cell strength could help identify drugs for asthma, hypertension and muscular dystrophy
Engineers, doctors and scientists at UCLA and Rutgers University have developed a tool that measures the physical strength of individual cells 100 times faster than current technologies.The new device could make it easier and faster to test and evaluate new drugs for diseases associated with abnormal levels of cell strength, including hypertension, asthma and muscular dystrophy. It could also open new avenues for biological research into cell force. It is the first high-throughput tool that can measure the strength of thousands of individual cells at a time.“Our tool tracks how much force individual cells exert over time...

Active role of capillary pericytes during stimulation-induced activity and spreading depolarization
AbstractSpreading depolarization is assumed to be the mechanism of migraine with aura, which is accompanied by an initial predominant hyperaemic response followed by persistent vasoconstriction. Cerebral blood flow responses are impaired in patients and in experimental animals after spreading depolarization. Understanding the regulation of cortical blood vessels during and after spreading depolarization could help patients with migraine attacks, but our knowledge of these vascular mechanisms is still incomplete. Recent findings show that control of cerebral blood flow does not only occur at the arteriole level but also at ...

Review on the Diagnosis and Treatment of Reversible Cerebral Vasoconstriction Syndrome in Children and Adolescents
Semin Neurol DOI: 10.1055/s-0040-1702942Reversible cerebral vasoconstriction syndrome (RCVS) is a clinical–radiologic diagnosis that affects children and adolescents, but it is much more frequently reported in adults. Clinically, patients present with severe and commonly recurrent thunderclap headaches. Typical precipitating triggers include vasoactive substances, serotonergic agents, and the postpartum period. There may be associated neurologic complications at presentation or in the weeks following, such as convexity subarachnoid hemorrhage, stroke, cerebral edema, cervical artery dissection (CeAD), and seizures. Angio...

Current Treatment Options in Cardiovascular Medicine: Update on Reversible Cerebral Vasoconstriction Syndrome
ConclusionRCVS can now be accurately diagnosed using clinical and imaging features available upon presentation. Advances in knowledge about the risk factors, prognosis, and potential harmful effects of certain therapeutic strategies, are expected to optimize the management of this increasingly well recognized syndrome.

A mathematical model for persistent post-CSD vasoconstriction
by Shixin Xu, Joshua C. Chang, Carson C. Chow, Kevin C. Brennan, Huaxiong Huang
Cortical spreading depression (CSD) is the propagation of a relatively slow wave in cortical brain tissue that is linked to a number of pathological conditions such as stroke and migraine. Most of the existing literature investigates the dynamics of short term phenomena such as the depolarization and repolarization of membrane potentials or large ion shifts. Here, we focus on the clinically-relevant hour-long state of neurovascular malfunction in the wake of CSDs. This dysfunctional state involves widespread vasoconstriction and a general disr...

SMART Syndrome Identification and Successful Treatment
We report a 41-year-old male patient admitted to our emergency room with a reduced level of consciousness and global aphasia. One month prior to admission, he started with frequent headache attacks of moderate intensity and paroxysmal behavioral alterations, advancing to confusion, gait instability, language impairment, and somnolence. He had a history of medulloblastoma treated with surgical resection followed by craniospinal irradiation 21 years before symptom onset. After excluding more frequent causes for the patient ’s symptoms along with a suggestive image pattern, we started treatment for SMART syndrome with high-...

CACNA1A-associated epilepsy: Electroclinical findings and treatment response on seizures in 18 patients
Eur J Paediatr Neurol. 2021 May 26;33:75-85. doi: 10.1016/j.ejpn.2021.05.010. Online ahead of print.ABSTRACTCACNA1A pathogenic mutations are involved in various neurological phenotypes including episodic ataxia (EA2), spinocerebellar ataxia (SCA6), and familial hemiplegic migraine (FHM1). Epilepsy is poorly documented. We studied 18 patients (10 males) carrying de novo or inherited CACNA1A mutations, with median age of 2,5 years at epilepsy onset. Eight mutations were novel. Two variants known leading to gain of function (GOF) were found in 5 patients. Five other patients had non-sense variants leading to loss of function ...

Vitamin D and its possible relationship to neuroprotection in COVID-19: evidence in the literature
Curr Top Med Chem. 2022 Apr 1. doi: 10.2174/1568026622666220401140737. Online ahead of print.ABSTRACTVitamin D is a hormone involved in the regulation of important biological processes such as signal transduction, immune response, metabolic regulation and also in the nervous and vascular systems. To date, coronavirus disease 2019 (COVID-19) infection does not have a specific treatment, however various drugs have been proposed, including those that attenuate the intense inflammatory response and recently the use of vitamin D, in clinical trials, as part of the treatment of COVID-19 has provided promising results. It has bee...
