The growing prevalence of dementia makes it important for us to better understand its pathophysiology and treatment modalities, to improve the quality of life of patients and caregivers. Alzheimer’s disease (AD), a neurodegenerative disease, is the most common form of amnestic dementia in the geriatric population. Pathophysiology of AD is widely attributed to aggregation of amyloid-beta (Aβ) plaques and hyperphosphorylation of tau proteins. Initial treatment modalities aimed to increase brain perfusion in a non-specific manner. Subsequent therapy focused on rectifying neurotransmitter imbalance in the brain. Newer drugs modify the progression of the disease by acting against aggregated Aβ plaques. However, not all drugs used in therapy of AD have been granted approval by the United States Food and Drug Administration (FDA). This review categorizes and summarizes the FDA-approved drugs in the treatment of AD in a manner that would make it a convenient reference for researchers and practicing physicians alike. Drugs that mitigate symptoms of dementia may be categorized into mitigators of Behavioral and Psychological Symptoms of Dementia (BPSD), and mitigators of cognitive decline. BPSD mitigators include brexpiprazole, an atypical antipsychotic with a once-daily dosage suited to treat agitation in dementia patients, and suvorexant, an orexin receptor antagonist used to treat sleep disturbances. Cognitive decline mitigators include cholinesterase inhibitors such as donepezil, rivastigmine, and galantamine and glutamate inhibitors such as memantine. Donepezil is the most commonly prescribed drug. It is cheap, well-tolerated, and may be prescribed orally once daily, or as a transdermal patch once weekly. It increases ACh levels, enhances oligodendrocyte differentiation and also protects against Aβ toxicity. However, regular cardiac monitoring is required due to reports of cardiac conduction side effects. Rivastigmine requires a twice-daily oral dosage or once-daily replacement of transdermal patch. It has fewer cardiac side effects than donepezil, but local application-site reactions have been noted. Galantamine, in addition to improving cognitive symptoms in a short span of time, also delays the development of BPSDs and has minimal drug-drug interactions by virtue of having multiple metabolic pathways. However, cardiac conduction disturbances must be closely monitored for. Memantine, a glutamate regulator, acts as an anti-Parkinsonian agent and an antidepressant, in addition to improving cognition and neuroprotection, and requires a once-daily dosage in the form of immediate-release or sustained-release oral tablets. Disease-modifying drugs such as aducanumab and lecanemab reduce the Aβ burden. Both act by binding with fibrillary conformations of Aβ plaques in the brain. These drugs have a risk of causing amyloid-related imaging abnormalities, especially in persons with ApoE4 gene. Aducanumab is administered once every 4 weeks and lecanemab once ever

Objectives: In developing nations such as India, a disparity exists between the available resources for stroke rehabilitation and the substantial burden of stroke cases. Consequently, the provision of cost-effective and multidisciplinary post-stroke rehabilitation care to stroke survivors becomes of paramount importance. The utilization of mobile applications (apps) for stroke care has been on the rise, offering a personalized and pragmatic solution with the potential for wider reach in settings constrained by limited resources. To address the unmet needs in the prevention and management of post-stroke complications, we conceptualized a strategy known as a mobile application-based post-stroke care strategy for both survivors and their caregivers. Materials and Methods: The scope of the app’s focus was determined based on the incidence of post-stroke complications within a prospective cohort of stroke patients, in conjunction with existing literature. An initial “web-based mobile app” prototype was crafted to align with the identified focus area. Before the development of the final app version, a feasibility study was conducted involving 30 participant dyads (comprising a patient and a caregiver). Content validity was evaluated by a panel of 20 stroke experts encompassing neurologists, nurses, physiotherapists, and psychologists. Results: The “Stroke Home Care” (SHC) mobile app was conceived as a web-based educational tool aimed at preventing and managing post-stroke complications. It seeks to train caregivers of immobile stroke patients in the administration of preventive and therapeutic care procedures, thereby potentially enhancing survivors’ quality of life and alleviating caregivers’ burden. The feasibility and validity studies indicated “high satisfaction” levels among most caregivers and experts (>75%), with the remainder expressing “satisfaction” and no “dissatisfaction” regarding app utilities. Stroke experts unanimously deemed the app “appropriate”, with consensus on contents, video quality, video length, and voice clarity. Caregivers reported “satisfactory” user experiences, encountering no issues during app installation or operation. Suggestions from both caregivers and experts were integrated into the final app version. Conclusion: The “SHC” app represents a feasible and well-received innovation tailored for the use by caregivers of stroke survivors. Consequently, the initial feasibility of the developed app serves as a precursor to a randomized controlled clinical trial aimed at substantiating its effectiveness within the post-stroke survivor and caregiver population. Notably, within resource-constrained contexts, this app has the potential to be a pivotal tool for post-stroke care.

Objectives: This study reviews the effect of albumin-induced volume expansion therapy on symptomatic vasospasm and clinical outcome in aneurysmal subarachnoid hemorrhage (aSAH). Materials and Methods: Computer searches carried out from the Scopus, Medline, Embase, Web of Science, the Cochrane Library, and Internet documents; hand searching of medical journals; and review of reference lists. Randomized controlled trials (RCT) and observational studies (OSs) comparing albumin therapy in combination or alone with crystalloid therapy for the treatment of cerebral vasospasm in aSAH were included in the study. Risk-of-bias assessment was conducted using ROB2.0 and ROBINS-I tools for RCTs and Oss, respectively. Results: Out of a total of 1078 searches, one RCT (published in two articles) and one observational (retrospective) study were included for final analysis. In RCT, albumin was used for volume expansion therapy with a baseline crystalloid regime and comparison made between hypervolemic and normovolemic groups and it showed no beneficial effects on symptomatic vasospasm and clinical outcomes based on the Glasgow outcome scale. Furthermore, the use of albumin showed a tendency for sodium retention with lowering of glomerular filtration rate, limiting the amount of total fluid required for targeted central venous pressure values, and thereby avoiding fluid overload manifestations. The retrospective study results between albumin versus non-albumin groups (crystalloids only) supported improved outcomes in the former group with lower in-hospital mortality. Cardiorespiratory complications were equivocal in RCT and increased in non-albumin group in the retrospective study. Risk-of-bias assessment analyses revealed “some concerns” in RCT and “serious” limitation in OS due to its retrospective design. Conclusion: Albumin-induced volume expansion therapy for cerebral vasospasm does not have substantiative evidence to improve cerebral vasospasm and clinical outcomes in aSAH. Studies with well-designed RCTs are required to compare the use of albumin for volume expansion therapy versus standard fluid management using crystalloids to mitigate the scarcity of published data.
目的:本研究回顾了白蛋白诱导的容量扩张治疗对动脉瘤性蛛网膜下腔出血(aSAH)症状性血管痉挛和临床结局的影响。材料和方法:计算机检索从Scopus, Medline, Embase, Web of Science, Cochrane Library和互联网文档中进行;手工检索医学期刊;查阅参考书目。随机对照试验(RCT)和观察性研究(OSs)比较白蛋白治疗联合或单独与晶体治疗治疗aSAH脑血管痉挛。对随机对照试验和操作系统分别使用ROB2.0和ROBINS-I工具进行风险偏倚评估。结果:在总共1078项检索中，一项RCT(发表在两篇文章中)和一项观察性(回顾性)研究被纳入最终分析。在随机对照试验中，白蛋白被用于容量扩张治疗和基线晶体方案，并在高容血和等容血组之间进行了比较，根据格拉斯哥结果量表，白蛋白对症状性血管痉挛和临床结果没有有益的影响。此外，白蛋白的使用显示出钠潴留的趋势，降低肾小球滤过率，限制了目标中心静脉压值所需的总液体量，从而避免了液体过载的表现。白蛋白组与非白蛋白组(仅晶体类)之间的回顾性研究结果支持前一组的预后改善，住院死亡率较低。在回顾性研究中，非白蛋白组的心肺并发症有所增加。偏倚风险评估分析显示RCT存在“一些问题”，而OS由于其回顾性设计而存在“严重”的局限性。结论:白蛋白诱导的容量扩张治疗脑血管痉挛并没有实质性的证据可以改善aSAH患者的脑血管痉挛和临床结果。需要设计良好的随机对照试验来比较白蛋白用于体积扩张治疗与使用晶体的标准液体管理，以减轻已发表数据的稀缺性。

Objectives: Secondary prevention of stroke largely depends on risk factor control and lifestyle modification. Optimal secondary prevention strategies are limited in rural settings due to the shortage of primary care physicians and neurologists. Awareness of community health workers (CHWs) regarding stroke and its management remains largely unexplored. The current cross-sectional study aimed at assessing the knowledge, attitude, and practice (KAP) of CHWs regarding stroke care. Materials and Methods: A structured KAP questionnaire was administered among 510 CHWs from randomly selected rural health blocks of Thiruvananthapuram, Kerala, India. Results: Knowledge assessment showed that the CHWs possessed an average knowledge of stroke care. The mean attitude and practice scores were higher, indicating a favorable attitude and good practice. The overall mean (standard deviation) KAP scores of CHWs were 13.54 (4.43) against a total score of 23. The KAP scores were highest among palliative care nurses. The stroke awareness of the accredited social health activists was comparatively lower than other CHWs. Factors such as age and years of work experience were not correlated to the KAP scores. Conclusion: Recurrent strokes remain a major challenge in primary care. Overall, the health workers demonstrated average knowledge, favorable attitudes, and positive practices. The study highlights the importance of training accredited social health activists (ASHAs) and other CHWs in stroke to improve secondary prevention strategies.

Spasticity is a velocity-dependent increase in muscle resistance associated with hypertonia after an acute stroke. Spasticity is expected to appear within a few weeks due to different mechanisms; we are reporting acute spasticity observed at the time of ischemic stroke involving the superior frontal gyrus and anterior cingulate gyrus. A healthy 64-year-old male patient suffered from subarachnoid hemorrhage secondary to aneurysmal rupture of the anterior communicating artery. He was referred to our center and treated with percutaneous transluminal coil embolization. In post-coiling, he developed acute left-sided weakness and spasticity. Magnetic resonance imaging brain showed an acute ischemic stroke involving the superior frontal gyrus and anterior cingulate gyrus. Patient follow-up showed improvement of weakness and spasticity. Therefore, acute spasticity can be related to a stroke involving the superior frontal gyrus and anterior cingulate gyrus.

Intracranial hypotension (IH) represents a syndrome secondary to low cerebrospinal fluid pressure. This case of IH following a lumbar drain inserted before the excision of a left intraconal lesion, leading to recurrent post-operative unilateral subdural and extradural collections, was treated successfully with the evacuation of the collection and simultaneous epidural blood patch (EBP) injection. Our report provides an important perspective on the management of IH with recurrent intracranial collections and reiterates that IH should be considered when dealing with recurrent unilateral intracranial collections in the post-operative period. Evacuation with a simultaneous EBP is an effective strategy for managing IH.

Objectives: Resistive index (RI) and pulsatility index (PI) assessed on carotid Doppler assess the hemodynamic status of cranial vasculature. They are related to the severity of stroke and help determine the overall outcome. This study was done to compare the hospital stay and stroke severity with RI and PI of both internal carotid arteries. Materials and Methods: Patients >18 years of age presenting within 48 h of anterior circulation stroke (either ischemic or hemorrhagic) were included. They were divided into two groups based on their length of stay (LOS). They were assessed clinically on days 1, 3, and 5, and underwent a carotid Doppler study on the same days. The Doppler parameters were correlated with the LOS and stroke severity for possible associations. Results: One hundred and one patients were included. Forty-seven patients had a favorable outcome based on LOS. In this group, significant decrease in RI and PI scores was seen from days 1 to 3. In patients with unfavorable outcome, there was a significant increase in PI on days 1–3 and days 1–5. The National Institutes of Health Stroke Scale decreased significantly from days 1 to 5 in favorable group Conclusion: For those with an unfavorable outcome and prolonged LOS, PI continues to increase suggesting a failure of autoregulation. Carotid Doppler can be a simple bedside tool to predict outcome in patients with acute stroke.

They are related to the severity of stroke and help determine the overall outcome. This study was done to compare the hospital stay and stroke severity with RI and PI of both internal carotid arteries. Materials and Methods: Patients >18 years of age presenting within 48 h of anterior circulation stroke (either ischemic or hemorrhagic) were included. They were divided into two groups based on their length of stay (LOS). They were assessed clinically on days 1, 3, and 5, and underwent a carotid Doppler study on the same days. The Doppler parameters were correlated with the LOS and stroke severity for possible associations. Results: One hundred and one patients were included. Forty-seven patients had a favorable outcome based on LOS. In this group, significant decrease in RI and PI scores was seen from days 1 to 3. In patients with unfavorable outcome, there was a significant increase in PI on days 1–3 and days 1–5. The National Institutes of Health Stroke Scale decreased significantly from days 1 to 5 in favorable group Conclusion: For those with an unfavorable outcome and prolonged LOS, PI continues to increase suggesting a failure of autoregulation. Carotid Doppler can be a simple bedside tool to predict outcome in patients with acute stroke.","PeriodicalId":16443,"journal":{"name":"Journal of Neurosciences in Rural Practice","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135959905","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}

Pineal cysts are usually benign, fluid-filled sacs and most pineal cysts are asymptomatic. Sudden death specifically related to pineal cysts is extremely uncommon. A literature review of the pertinent databases, including PubMed, Google Scholar, Scopus, and Web of Science, was carried out to review the existing literature describing sudden death in patients with pineal cysts. In the evaluation of 49 articles, it was found that four reports discussed the unexpected death of patients who had pineal cysts. A total of four cases of sudden death and a pineal cyst were reported. There were 75% females and a mean age of 29 (range: 20–45). Cyst size on average was 1.3 cm (1.2–1.5). In each case, the cause of death and the involvement of important brain structures were confirmed by autopsy results. A pathological analysis of the pineal region and the surrounding brain tissue revealed a variety of lesions. Vascular malformation was found in one case, adding another layer of complexity to the study of sudden death syndrome. In this research, the authors highlight the fact that patients with pineal cysts can experience serious, even fatal, complications. Increased vigilance and early detection through neuroimaging and neurological assessments are required due to the wide variety of clinical manifestations and underlying mechanisms. To explain the mechanism and enhance the management and prevention of sudden deaths associated with pineal cysts, additional research with larger sample sizes is required.
松果体囊肿通常是良性的，充满液体的囊，大多数松果体囊肿是无症状的。与松果体囊肿相关的猝死极为罕见。对PubMed、Google Scholar、Scopus和Web of Science等相关数据库进行文献综述，对现有的描述松果体囊肿患者猝死的文献进行综述。在对49篇文章的评价中，发现有4篇报道讨论了松果体囊肿患者的意外死亡。报告了4例猝死和1例松果体囊肿。女性占75%，平均年龄29岁(范围:20-45岁)。囊肿平均大小1.3 cm(1.2 ~ 1.5)。在每一起案件中，死因和重要脑结构的受累都得到了尸检结果的证实。松果体区和周围脑组织的病理分析显示了多种病变。一例发现血管畸形，为猝死综合征的研究增加了另一层复杂性。在这项研究中，作者强调了松果体囊肿患者可能会经历严重甚至致命的并发症这一事实。由于临床表现和潜在机制的多样性，需要通过神经影像学和神经学评估提高警惕和早期发现。为了解释这一机制并加强与松果体囊肿相关的猝死的管理和预防，还需要进行更大样本量的额外研究。
