It was shown that occurrence of AIS in coronavirus disease -19 (COVID-19) was correlated with the severity of respiratory illness [1, 2]. Despite many reports of AIS and COVID-19 in older patients with established cardiovascular risk factors, there are several reports of AIS in young patients without any significant past medical history or cardiovascular risk factors [2, 3]. Such reports suggest hypercoagulability and/or endothelial dysfunction within the arteries of the COVID-19 patients. Furthermore, it has been shown that inflammation and hypercoagulable processes contribute to developing both venous and arterial thromboembolism following infection with SARS-CoV-2 [1, 4-7]. These potential mechanisms as well as the clinical and epidemiological differences in patients with COVID-19 compared to non-COVID-19 patients, raise the question of the optimal secondary stroke prevention antithrombotic regimen in young COVID-19-related AIS patients. To address such an important question, there is need for randomized clinical trials and high-quality prospective studies with reasonable duration of follow-up. However, given lack of such studies to date, we aimed to review the limited current literature to investigate the optimal antithrombotic regimen for secondary prevention strategy in this group of patients. We carried out a review in PubMed to find all articles evaluating secondary prevention of AIS following COVID-19 from December 1, 2019 to June 30, 2020. The keywords: “COVID-19” or “SARS-CoV-2 “or “coronavirus” and “stroke” or” cerebrovascular” and “treatment “or “secondary prevention” were used in different combinations. All pertinent case reports, case series and original research articles in English language were included. The literature search revealed 430 articles. After eliminating the duplications and non-relevant articles, seven articles were included in the study. We identified only the patients with COVID-19-related AIS who did not have any pertinent past medical history or cardiovascular risk factor and were 50 years old or younger. Data for secondary prevention antithrombotic regimen in 16 patients with above-mentioned inclusion criteria were available. Mean age of the patients was 39.5 years (range: 31 50). Anticoagulation was administered for 10 (62.5%), single antiplatelet for three (18.7%) and dual antiplatelet for three (18.7%) patients (Table 1) [2-4, 8-11]. Despite the fact that several studies have shown the possibility of hypercoagulable state in the young COVID-19 patients, so far, no consensus on the secondary prevention antithrombotic regimen exists. Furthermore, the optimal secondary prevention measures in this particular group of patients might differ from the usual secondary prevention strategies in AIS patients with established cardiovascular risk factors [12].

Emamzadehfard","doi":"10.14740/jnr628","DOIUrl":"https://doi.org/10.14740/jnr628","url":null,"abstract":"The goal of this review is to provide a guide to magnetic resonance imaging (MRI) reading for non-radiologists. A thorough literature search was conducted using the keywords “MRI”, “CT”, “Non-radiologist” and “MRI interpretation” to develop an approach to MRI reading for non-radiologists. Common indications for a brain MRI include workup of an intracranial tumor, chronic headache, seizure disorder, and confirmation of a stroke. When assessing for an intracranial tumor, MRI is the preferred diagnostic modality. Computed tomography (CT) has much lower resolution and is typically reserved for the emergency setting. T1 weighted images provide anatomically relevant images of the brain parenchyma that will be familiar to non-radiologists. In contrast to T1 weighted images, fluid is bright in T2 and white matter will appear darker than gray matter. Fluid attenuation inversion recovery (FLAIR) is most sensitive for edema and parenchymal abnormalities like a low-grade glioma. The main purpose of diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) sequences are to visualize acute ischemic stroke. Although non-radiologists generally have a greater exposure to head CT images, the same foundational principles of CT head interpretation can apply to brain MRI reading. Benefits of brain imaging by MRI includes obtaining a multi-planar assessment of the brain, highly detailed images of the brain, and using different MRI sequences to assess for different pathology.

Seifi","doi":"10.14740/jnr609","DOIUrl":"https://doi.org/10.14740/jnr609","url":null,"abstract":"Background: After spinal cord injury (SCI), patients are seen in either trauma center emergency departments (EDs) or non-trauma center EDs, and then selectively admitted for hospitalization. The association between SCI and admission to designated trauma centers is currently unknown. In this study, we assess the trends in admission between designated trauma centers after SCI from a large multi-center nationwide registry. Methods: In this retrospective analysis of the Nationwide Emergency Department Sample (NEDS), we identified visits with SCI from 2006 to 2014. Z-test analyses were used to compare patients diagnosed with SCI at EDs with an associated trauma center designated hospital (TC-visits) against patients diagnosed with SCI at EDs without an associated trauma center designated hospital (NTC-visits). Results: A total of 516,716 reported visits were identified with SCI. The annual total ED visits with admission to the same hospital for patients diagnosed with SCI increased significantly from 39,129 to 50,127 from 2006 to 2014 (P < 0.001). From 2006 to 2014, the annual ED visits and admissions from TC-visits increased significantly from 27,781 to 43,926 and 23,445 to 35,635, respectively (P < 0.0001, P < 0.0001). However, the annual ED visits and admissions from NTC-visits did not change significantly from 23,938 to 22,107 and 15,683 to 14,493, respectively (P = 0.09 and P = 0.1). Throughout the entire study period, the annual total ED visits with admissions to the same hospital was significantly higher for TC-visits than NTC-visits diagnosed with SCI (P < 0.0001). The mean length of stay (14.1 days vs. 8.1 days), annual total in-hospital mortality (6.8% vs. 6.0%), and annual total discharges to another institution (53.8% vs. 46.8%) were significantly higher in TC-visits throughout the study period (P < 0.001). However, the annual total routine discharges (27.2% vs. 26.4%), annual total discharges to short-term hospital (12.4% vs. 7.2%), and annual total discharges to home health care (7.7% vs. 4.4%) were significantly higher in NTC-visits throughout the study period (P < 0.001). Conclusions: Of the population of patients with SCI who visit EDs, those seen at trauma centers have a significant parallel association with incidence and patient outcome compared against those seen at non-trauma centers. Prospective research is warranted to make recommendations for required healthcare infrastructures based on an institution’s trauma center designation.

There are controversies with regards to whether repetitive transcranial magnetic stimulation (rTMS) could improve the condition. Methods: In a randomized, self-control, crossover clinical trial, effect of rTMS on cognitive performance in patients with MCI was assessed. Patients were randomized into two study groups (A and B) and received both rTMS procedure and sham therapy in sequence, with each lasting for 8 weeks. Montreal cognitive assessment (MoCA) test was performed as a cognition battery at baseline and 1 week after each 8-week period of interventions. Results: Sixteen patients were enrolled in the study. Baseline measures of MoCA were statistically equal between two groups (P value = 0.10). Mean MoCA score significantly increased in group A at nine-week follow-up compared to both group B (P value < 0.001) and its baseline (P value = 0.01). However, at 18-week follow-up, mean MoCA scores were increased in both groups compared to their baseline (both P values < 0.001) with no significant differences between study groups (P value = 0.87). No adverse effects were reported. Conclusions: The rTMS is suggested as an effective and safe therapeutic option for cognitive improvement in patients with MCI.

Brain abscesses arise from direct contiguous spread, hematogenous spread, neurosurgical procedures, open traumatic brain injuries, and cryptogenic sources. Early identification is pivotal, as delayed diagnosis and treatment lead to a very poor prognosis. Our case illustrates an elderly gentleman with a history of adenoid cystic carcinoma (ACC) of the oropharyngeal palate who presented to an outside hospital with severe headaches and was found to have a questionable metastatic lesion to his left temporal region. He was discharged with a course of steroids. Weeks later his headaches persisted, mentation further declined and repeat imaging revealed the same abnormal lesion. He subsequently underwent a craniotomy and was found to have a significant temporal abscess and empyema, which were evacuated. Post-operatively his course was complicated by status epilepticus requiring intubation and he was ultimately placed on hospice care. Our case illustrates the importance of early recognition and intervention for suspicious lesions, particularly when predisposing risk factors exist.

Patients’ social and occupational functioning in the inter-episode interval was also compared. Methods: A total of 324 patients that were admitted in our psychiatry ward with diagnosis of BD, manic phase, were surveyed for their past psychiatry history. The patients entered the study if they had adhered to their mood stabilizing medications from their past mood episode till this current mood episode. A total of 169 patients were on lithium (mean dose: 785.7 mg) and 155 patients were on Na valproate (mean dose: 734.3 mg) while admitted. The time period the patients were in the inter-episode interval was compared between the two groups. The patients’ occupational and social functioning in the inter-episode interval was also compared. Results: The inter-episode interval was 28.7 months in the patients taking lithium and 29.4 months in the patients on Na valproate. There was no significant difference in this regard between the two groups (P = 0.564). Furthermore, rates of substance abuse (0.561), divorce (0.543), suicidal attempt (0.693) and unemployment (P = 0.453) in the inter-episode interval did not differ significantly between the lithium and valproate groups. Conclusions: Na valproate was demonstrated to be as effective as lithium in preventing mood episode recurrence in bipolar patients. Our patients also demonstrated comparable occupational and social status in the inter-episode interval.

Both upper motor neurons and lower motor neurons are targeted. It is hypothesized that: edaravone is effective at managing ALS. This review article used a combination of secondary and primary research articles to gain a plethora of information to help test this hypothesis. Using PubMed, research articles were studied to identify important information. For the Introduction, both secondary and primary articles were used without a limitation on publication date. For the Results section, only primary articles were used which had to have been published no earlier than 2006. The Results section of this review helped to support the hypothesis that edaravone is effective at managing ALS. The most pivotal efficacy endpoint, the change in the Amyotrophic Lateral Sclerosis Functional Rating Scale Revised score, was positively influenced by edaravone over the placebo. This was shown to be statistically significant by use of analysis of variance, amongst other statistical tests. Secondary endpoints such as forced vital capacity and pinch strength were also analyzed, showing similar favorable results. From the clinical trials analyzed in this review, it is concluded that edaravone is sufficient in treating ALS. Edaravone is limited to a target population which could prove to be a problem. Future studies should explore this issue in hopes of expanding the treatment population of edaravone.

Mowla","doi":"10.14740/jnr621","DOIUrl":"https://doi.org/10.14740/jnr621","url":null,"abstract":"The year 2020 marks the silver jubilee of the landmark National Institute of Neurological Disorders and Stroke (NINDS) trial which made intravenous tissue plasminogen activator (IV tPA) the only Food and Drug Administration (FDA)-approved treatment for acute ischemic stroke (AIS) management thus far [1]. Over the years, the use of IV tPA has become safer and ubiquitous [2-8]. 2020 also marks the fifth anniversary of the five large randomized clinical trials (RCTs) which revolutionized acute stroke care by endorsing the benefits of concomitant use of IV tPA and endovascular treatment (EVT) with stent retrievers over IV tPA alone in large vessel strokes [9]. EVT with stent retrievers have demonstrated to improve the overall functional outcome and reduce mortality in large vessel strokes, with or without IV tPA [9]. While the efficacy of IV tPA in AIS has been well validated, recently and in the era of effective EVT, its use in AIS with large vessel occlusion (LVO) has been debated. We are at a critical juncture in the ever evolving and exciting field of AIS care, the question on every neurologist’s mind remains whether to bypass IV tPA for EVT in AIS with LVO. Is it the end of the road for IV tPA in AIS with LVO? It has been largely recognized that IV tPA has a low rate of recanalization in AIS with LVO. In a computed tomography (CT) angiogram-based retrospective study, only 21% of the AIS patients with LVO who received IV tPA within 4.5 h of symptom onset achieved complete recanalization [10]. The same study noted much lower rates of recanalization in the case of proximal internal carotid artery and basilar artery occlusions, approximately 4% [9]. Rai et al concluded that administration of IV tPA before EVT for large vessel strokes single handedly increased the total length of hospital stay and the health care costs [11]. It is well known that early recanalization of an occluded intracranial large vessel leads to better functional outcome. Combination therapy increases the door to groin puncture time of EVT that may lead to delayed recanalization time and subsequently worse functional outcomes [12]. Furthermore, the results of the recently published SKIP trial [13], comparing EVT with versus without IV tPA in AIS with internal carotid artery (ICA) and M1 occlusions, showed a lower rate of intracranial hemorrhage in the EVT only group (34% vs. 50%, P = 0.02). There is also a concern that IV tPA administration might fragment a blood clot targeted for extraction and potentially propagate the fragments downstream, making it non-amenable to EVT [14]. Kamal et al [15] also reported the possibility of recurrent AIS early after IV tPA administration due to disintegration of a pre-existing intracardiac, valvular or aortic thrombus and subsequent systemic embolization. Since health care providers usually think of intracranial hemorrhage as the cause of neurological deterioration during or shortly after IV thrombolysis (IVT), this might cause a delay in the ","PeriodicalId":16489,"journal":{"name":"Journal of Neurology Research","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87434181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim is to survey the risk factors and antipsychotic medications associated with more relapses in schizophrenia patients. Methods: The records of 251 schizophrenia patients who were adherent to their antipsychotic medications during the course of their illness were surveyed. The files were divided to two groups with regard to the number of admissions. The groups were compared regarding age, sex, education, marital status, place of living, family history, positive or negative symptom profile, substance abuse and the antipsychotic medications used. Results: The patients of the two groups did not show any differences regarding demographic factors. The dominant antipsychotic (the antipsychotic used more than 50% of time during the course of illness) used in the two groups was risperidone without significant difference (P = 0.486). Only substance abuse (P = 0.090) and electroconvulsive therapy (ECT) administration (P < 0.001) were shown to be different between the groups.
