Cerebral Hyperperfusion Syndrome After Carotid Revascularization and Acute Ischemic Stroke
AbstractPurpose of ReviewCerebral hyperperfusion syndrome (CHS) is a rare but significant complication after carotid revascularization and is increasingly recognized after acute stroke treatments. In this review, we discuss the epidemiology and pathophysiology of CHS, clinical presentation including ipsilateral headache, seizures, and focal neurological deficits, and radiographic presentation. We propose preventive therapies with emphasis on acute stroke post-thrombectomy hyperperfusion.Recent FindingsCHS was first described after carotid revascularization but is now also reported in patients with acute ischemic stroke. Pr...

Antiplatelet treatment compared with anticoagulation treatment for cervical artery dissection (CADISS): a randomised trial
Publication date: Available online 12 February 2015 Source:The Lancet Neurology Background Extracranial carotid and vertebral artery dissection is an important cause of stroke, especially in young people. In some observational studies it has been associated with a high risk of recurrent stroke. Both antiplatelet drugs and anticoagulant drugs are used to reduce risk of stroke but whether one treatment strategy is more effective than the other is unknown. We compared their efficacy in the Cervical Artery Dissection in Stroke Study (CADISS), with the additional aim of establishing the true risk of recurrent stroke. Methods W...

Combination of Dexmedetomidine and Ketamine for Magnetic Resonance Imaging Sedation
Conclusions: The efficacy of DEX–KET sedation was comparable to that of midazolam for MRI examination. DEX–KET was related to shorter scan time and lower occurrence of complications compared to midazolam. Introduction Neurocritically ill patients often require brain magnetic resonance imaging (MRI) in addition to conventional neurological evaluations. Brain MRI can reveal structural lesions with a high sensitivity due to its excellent spatial resolution and enhanced soft tissue contrast (1–3). To acquire MRI images, patients' cooperation is imperative. However, keeping patients with ...

Treatment of Post-Influenza Vaccination Induced Acute Disseminated Encephalomyelitis (ADEM) with Plasma Exchange - A Case Report (P4.036)
DISCUSSION:Influenza vaccination has been rarely linked to ADEM. Due to a low-incidence of the disease, there are no established treatment guidelines. Our patient did not respond to steroids but showed marked radiographic improvement with PE. PE should be considered for refractory ADEM after influenza vaccination.Disclosure: Dr. Chahil has nothing to disclose. Dr. Pillainayagam has nothing to disclose. Dr. Schulz has nothing to disclose.

Stroke-Like Migraine Attacks After Radiation Therapy (SMART) Syndrome: A Comprehensive Review
AbstractPurpose of ReviewSMART syndrome is a delayed complication of cranial irradiation that can be misconstrued as tumor recurrence or some other intracranial neurological disease. Recognition of this clinical syndrome is imperative as it can obviate the need for invasive diagnostic testing and can provide reassurance to both the patient and their loved ones.Recent FindingsSMART syndrome is generally considered a reversible clinical syndrome; however, neurological deficits may become permanent. Pathophysiology of SMART syndrome may involve cerebrovascular autoregulation impairment, neuronal dysfunction leading to trigemi...
