Method: This is a retrospective study of prospectively collected data of 25 cases with ruptured VADA managed by a standardized endovascular parent artery occlusion technique. All cases were treated with coil occlusion of the dilated segment with a short proximal segment of the involved non-dominant or co-dominant vertebral artery within 12 hours of admission. All cases were done under general anesthesia with no anticoagulation. Outcome was assessed clinically with modified Rankin score as well as follow up MRI at 6 months. Results: There were a total of 25 cases, 10 female and 15 males. Age range 18 to 70, mean age 41. Twenty cases (80%) were WFNS grade 1 to 3. Five cases were grade 4 to 5. Treatment complication of cerebellar embolic infarct occurred in one case (4%). There was no hemorrhagic complication post treatment. 16 cases required ventriculoperitoneal shunting. Outcome was good with modified Rankin score of 0 to 2 in 20 cases (80%). There were 5 poor outcomes including one death (4%) due to the primary effect of subarachnoid hemorrhage in a case presenting with WFNS grade 5. All cases with WFNS grade 1 to 3 at presentation obtained good outcome. In all 24 cases who survived, follow up MRI showed that all aneurysms remained occluded at 6 months. Conclusion: Endovascular parent artery coil occlusion is effective and durable for ruptured VADA.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"28 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74031009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It commonly affects patients over 50 years, and occurs more frequently in women. Treatment options include medical therapy, surgery (microvascular decompression (MVD) and percutaneous balloon compression (PBC)) and Gamma Knife® radiosurgery (GKRS). GKRS has been available at the Princess Alexandra Hospital since October 2015. Our objective was to evaluate the efficacy of GKRS on patients with TN and investigate the impact of known prognostic variables on patient outcomes. Method: A retrospective review was conducted on all patients who received GKRS for TN from October 2015 till March 2018 in a single center tertiary neurosurgical referral hospital. Results: 43 patients with TN were treated with GKRS with a median follow up time after treatment of 7 months (6 weeks - 36 months). Median age was 69 years, 51% were female and 21% had atypical symptoms. 33% previously had surgery (7=MVD, 7=PBC). Clinical benefit after GKRS was observed in 79% of patients at 1 month, 73% at 3 months, 74% at 6 months and 87% at 1 year. Of the 49% who experienced a relapse of pain within 1 year post GKRS, the median time to relapse was 8 weeks. No serious adverse events or severe toxicity were recorded. Patient and treatment factors that predicted worse outcomes were the presence of a vessel contacting the nerve, female gender and a higher radiation dose. Conclusion: GKRS is an effective treatment option for patients with TN and it is particularly useful to consider in those with co-morbidities that make surgery high risk. GKRS has acceptable short-term beneficial results in TN, however with relapse other treatment options may be required.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"18 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80491344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children are expected to be prepared for this and to receive a tablet or cell phone as early as possible. This, however, poses a huge risk because a child’s brain must initially organize itself in an analog fashion. This means that the spatial-modular building of neural networks and the rhythmic timing of brain activities mature very slowly through upbringing and school education to support memory formation and thinking. Once this foundation has been established, a digital workplace will be easily accessible to any young adult. To investigate in more detail the impacts of private cell phone use on the learning abilities of children, we designed a cognitive test that, among other things, measures spatiotemporal abilities and memory performance. A total of 54 third-grade students (aged 8 and 9) were subjected to the testing at an elementary school in the Rhein-Neckar-Kreis/Baden Württemberg region from December 2019 to March 2020. The intensity of private cell phone use was measured with a nonverbal method, the evidence-based water glass method. Prior to testing, we evaluated the children’s ability to evaluate themselves with this nonverbal method and designed a lie item, which allowed us to filter out those children who were unable to evaluate themselves. Due to the high data quality, variance analysis was used to analyze the quantified data statistically. The results showed that prefrontal cortex skills such as spatial perception, concentration, and anticipation were significantly poorer in third-graders with heavy cell phone use compared to those with little or no cell phone use. The heavier the cell phone use, the less well developed was their cognitive memory performance if it included a time delay. Furthermore, we observed a significant impact of the intensity of cell phone use on the motivation to go to school. The frequency of sports activities, playing outdoors, friendships, and homework was not significantly affected by cell phone use. The reason for this could be that modern schoolchildren only have rather limited control over the timing of these activities. Overall, the data suggest that other cognitive and emotional-motivational abilities such as spelling and handwriting are also adversely affected by heavy cell phone use. This could be verified by an investigation with a larger sample size. The findings of this pilot study should be a warning: with the digital transformation, our society could cause severe and also irreversible cognitive damage to the young generation. The discussion shows that brain research findings from the past half century provide comprehensive evidence for this","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"22 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85383690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is urgent to discover therapeutic methods against chemobrain. In fact, neither measurements nor mechanisms are yet to be defined. To discover efficient treatment on chemobrain, in this review, we firstly focus on applications of objective and accurate methods to study the measurement of chemobrain, such as Functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). Furthermore, we highlight the potential mechanism of chemobrain including neuroinflammation, cell apoptosis and synaptic degeneration. Chemotherapy can induce neuroinflammation and cell apoptosis in brain. Synaptic plasticity also decreased in chemo-agent treated mice. Based on other cognitive impairment diseased, we also engaged in looking for effective treatment on cognitive impairment after chemotherapy in cancer patients. Synaptic repair, stem cell transplantation, Chinese medicine and psychological rehabilitation are all powerful candidates for treating chemobrain.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"37 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72527387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By these reasons, some confirmatory complementary tests in many pathologies cannot be made or are postponed, including Myasthenia Gravis. Two clinical neurological signs useful for diagnosis of Myasthenia Gravis are revised: the “Curtain Sign” (also called paradoxical ptosis), that is evoked opening the more closed eye, which results in a dropping of the contralateral eyelid; and the Mary-Walker maneuver, which results from repetitive pronation-supination exercise under anaerobic conditions in one or both arms resulting in increasing of bilateral ptosis.

While the evolution of the head-and-neck mobility may have increased the overall fitness of homo sapiens, our head-and-neck mobility may have also introduced some differential vulnerability to injuries in impact-induced head rotations about the pitch, roll, and yaw axes. Methods and Findings: We examined impact-induced head rotations in boxing matches by analyzing videos. Our objective was to seek a quantitative relationship between impact-induced head kinematics and the knockout outcome. For each of the three rotational degrees of freedom, head angular velocities of impact-induced head rotations were significantly higher in knockout hits than in control hits without a knockout (p < 0.02). Knockout thresholds in pitch-roll-yaw measured as impact-induced head angular velocities were anisotropic with the lowest threshold in roll and became progressively higher in yaw and pitch, in that order. Regardless of the pitch-roll-yaw bearing, the velocities of the striking fists in knockout hits were not significantly higher than those in control hits. Conclusions: Accurate prediction of knockout via head kinematics was possible with pitch-roll-yaw information. Impact-induced head kinematics was strongly influenced by neck stiffness, making a case for the utility of reflexively increasing neck stiffness as an effective way to reduce impact-induced head rotations and concussion risk.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"68 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77268026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiment was held on 18 rats: 12 animals were undergoing bilateral filament occlusion of arteries carotid, 6 of them L-arginine and omega-3 PUFA was administrated. The drug omega-3 PUFA \"Omegamed\" (at a dose of 5 g/kg of body weight) was injected intragastrically during the week preceding the simulation of SIMG. L-arginine (at a dose of 100 mg/kg body weight) was injected intravenously just before ligation of the common carotid arteries. The analyses of free amino acids and their derivates levels in the blood plasma extracts were carried out by reversed phase HPLC. In the hippocampus of rats with SIGM, there was an increase in the levels of histidine, 3-methylhistidine, glutamine, α--aminobutyrate, isoleucine, leucine, valine, as well as a decrease in the levels of threonine, tyrosine, and α--aminoadipic acid. Administration of L-arginine and omega-3 PUFAs prevented ischemia-induced disruption of threonine, histidine, glutamine, α--aminobutyrate, α--aminoadipic acid levels, and also had a corrective effect on the serotonin system of the hippocampus.","PeriodicalId":21130,"journal":{"name":"Restorative neurology and neuroscience","volume":"111 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79618086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
