Regulation of Therapeutic Hypothermia on Inflammatory Cytokines, Microglia Polarization, Migration and Functional Recovery after Ischemic Stroke in Mice.
This study reveals the first evidence for hypothermia mediated regulation on inflammatory factor expression, microglia polarization, migration and indicates that the anti-inflammatory effect is an important mechanism underlying the brain protective effects of a TH therapy.

Mortality following status epilepticus in persons with and without epilepsy
Conclusion There is a statistically significant increased risk of all-cause mortality with SE. The risk is stronger in those with no prior epilepsy. Specific etiologies increase mortality risk in those with SE warranting further investigation of the complex associations between these etiologies and SE.

Panax notoginseng saponins administration modulates pro- /anti-inflammatory factor expression and improves neurologic outcome following permanent MCAO in rats
AbstractIschemic stroke, particularly permanent occlusion, accounts for the overwhelming majority of all strokes. In addition to the occlusion of arteries, the inflammatory response plays a pivotal role in the severity of the cerebral injury and its clinical prognosis. Here,panax notoginseng saponins (PNS) extracted from a traditional Chinese herbal medicine was administered following permanent middle cerebral artery occlusion (MCAO) in rats to explore the neuroprotective mechanisms against ischemic injury. The results showed that MCAO surgery was successful in producing an infarct and that PNS and nimodipine could amelior...

Intracerebral Hemorrhage Outcomes in Patients with Systemic Cancer
Single-center studies suggest that patients with cancer have similar outcomes after intracerebral hemorrhage (ICH) compared to patients without cancer. However, these studies were limited by small sample sizes and high rates of intratumoral hemorrhage. Our hypothesis was that systemic cancer patients without brain involvement fare worse after ICH than patients without cancer.

Tumor-Like Presentation of Primary Angiitis of the Central Nervous System Brief Reports
Conclusions— Patients with tumor-like presentation of primary angiitis of the central nervous system represent a subgroup characterized with mainly small-sized vessel disease that requires histological confirmation because vascular imaging is often normal. Although relapses are not uncommon, global outcomes are good under treatment with glucocorticoids and cyclophosphamide.

Helium preconditioning protects the brain against hypoxia/ischemia injury via improving the neurovascular niche in a neonatal rat model.
This study aimed to investigate whether helium preconditioning (He-PC) is able to exert neuroprotective effects via improving focal neurovascular niche in a neonatal rat hypoxia/ischemia (HI) brain injury model. Seven day old rat pups were divided into control group, HI group and He-PC group. HI was induced by exposure to 8% oxygen for 90min one day after preconditioning with 70% helium-30% oxygen for three 5-min periods. At 3 and 7 days, the brain was collected for the detection of inflammation related factors (tumor necrosis factor α [TNF-α], interleukin-1β [IL-1β], IL-10) and growth/neurotrophic factors (brain-deriv...

Mesenchymal stem cell ‐based treatments for stroke, neural trauma, and heat stroke
ConclusionThis review offers a testable platform for targeting microglial‐mediated cytokines in clinical trials based upon the rational design of MSC therapy in the future. MSCs that are derived from the placenta provide a great choice for stem cell therapy. Although targeting the microglial activation is an important approach to reduce the burden of the injury, it is not the only one. This review focuses on this specific aspect. Ischemic stroke, neural trauma, and heatstroke all cause cerebral ischemia‐related deficits. Exogenous MSC therapy is promising as a means of augmenting brain ischemia‐induced deficits. MSC...

Unusual case of recurrent SMART (stroke-like migraine attacks after radiation therapy) syndrome
Ramnath Santosh Ramanathan, Gayathri Sreedher, Konark Malhotra, Zain Guduru, Deeksha Agarwal, Mary Flaherty, Timothy Leichliter, Sandeep RanaAnnals of Indian Academy of Neurology 2016 19(3):399-401Stroke-like migraine attacks after radiation therapy (SMART) syndrome is a rare delayed complication of cerebral radiation therapy. A 53-year-old female initially presented with headache, confusion and left homonymous hemianopia. Her medical history was notable for cerebellar hemangioblastoma, which was treated with radiation in 1987. Her initial brain MRI (magnetic resonance imaging) revealed cortical enhancement in the right te...

Chapter 56 Diffusion tensor imaging and functional MRI
Publication date: 2016 Source:Handbook of Clinical Neurology, Volume 136 Author(s): Massimo Filippi, Federica Agosta The advances in diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), and functional magnetic resonance imaging (fMRI) over the last 20 years have vastly contributed to improving the understanding of the brain structure and function in patients with many diseases of the central nervous system (CNS). DWI is commonly used, for instance, in the diagnostic workup of stroke, CNS neoplasia, and rapidly progressive dementia cases. The new DTI methods provide more specific information about the most ...

Density heterogeneity and fluid-blood levels in patients aged over 55 with lobar hematoma.
CONCLUSION: Density heterogeneity and, to a lesser degree, FBLs are frequently seen in patients aged>55 with LH. FBLs may also be associated with CAA-related hemorrhage. PMID: 27338204 [PubMed - as supplied by publisher]

Recurrent episodes of isolated hemidystonia in a young adult: Dissection-associated stenosis in the middle cerebral artery
Dystonia is a hyperkinetic movement disorder, characterized by sustained involuntary muscle contractions leading to twisting or abnormal postures. Most cases of acquired hemidystonia result from brain lesions including stroke, trauma, or a tumor affecting the contralateral striato-thalamo-cortical pathway [1]. Besides, intermittent hemidystonia could be observed in patients with paroxysmal dystonia. However, to our knowledge, recurrent episodes of isolated hemidystonia, as the presenting symptom of transient ischemic attack (TIA), have not been reported.

Midbrain and bilateral paramedian thalamic stroke due to artery of Percheron occlusion.
CONCLUSION: Bilateral thalamic stroke due to artery of Percheron occlusion is a rare presentation of stroke, which can be overlooked in routine CT scan. If diagnosed, it requires further evaluation for stroke risk factors, especially cardiovascular disorders associated with increased embolic risk. PMID: 27154444 [PubMed - as supplied by publisher]
