VISIT STROKE: non-inferiority of telemedicine-based neurological consultation for post-acute stroke patients – protocol of a prospective observational controlled multi-center study

BackgroundTelemedicine provides specialized medical expertise in underserved areas where neurological expertise is frequently not available on a daily basis for hospitalized stroke patients. While tele-consultations are well established in acute stroke assessment, the value of telemedicine-based ward-rounds in the subsequent in-patient stroke management is unknown.MethodsFour telemedicine stroke networks in Germany, implemented in eight out of 16 federal states, participate in this prospective observational multi-center study. We plan to enroll 523 patients hospitalized due to acute (suspected or confirmed) stroke or transient ischemic attack. Each recruited patient will receive both a tele-consultation and an on-site consultation at the same day within the first three days after hospital admission. We will test non-inferiority of telemedicine-based assessments in ward-rounds in terms of quality of medical assessment and recommendations for hospitalized stroke patients. The correctness of the medical assessment and recommendation is defined as positive evaluation (binary, correct vs. in-correct) of six out of six predefined quality indicators by at least two out of three blinded independent raters. The non-inferiority margin for the difference in proportions of correct assessments is set to 5%-points.DiscussionIf non-inferiority of telemedicine-based ward-rounds compared to on-site ward-rounds by a neurologist were demonstrated, telemedicine-based neurological consultation for post-acute stroke patients may contribute to deliver evidence-based high-quality stroke care more easily in underserved regions.Trial registrationDRKS - DRKS00028671 (https://drks.de/search/de/trial/DRKS00028671; registration date 09-27-2022).

Autonomic nervous system education in Europe: EAN/EFAS/INUS survey on curricula and skills in autonomic medicine of European neurology residents and consultants.

Centers for training in autonomic nervous system (ANS) disorders are not widely available and the recent coronavirus 2019 pandemic temporarily reduced training opportunities in autonomic medicine across European countries. Here we evaluated the current state of education, clinical skills and postgraduate educational preferences on ANS disorders of European neurology residents and consultants. A 23-item questionnaire was developed and distributed online amongst European neurology residents and consultants via mailing lists of the European Academy of Neurology. The questions assessed demographics, current training opportunities and learning preferences in ANS disorders. Six multiple-choice questions were used to self-evaluate knowledge of ANS disorders. In all, 285 individuals answered the survey (60% female, mostly 25-34 years of age). All respondents considered clinical autonomic skills necessary for good clinical neurological practice, and 92% would like to increase their ANS knowledge. Female respondents and those who trained in Southern/Eastern/Greater Europe more frequently judged ANS skills important for clinical practice than male respondents (p = 0.012) and respondents from Northern/Western Europe (p = 0.011). Female and younger respondents felt less confident in managing ANS disorders (p = 0.001 and p < 0.001, respectively). Respondents below 45 years of age (p < 0.001) and those with lower confidence in managing ANS disorders (p = 0.004) were more likely to recommend that ANS education is embedded in the residency curriculum. Most European neurology residents and consultants reported a need for more autonomic education, with additional gender, age and regional differences. These findings underscore the importance of increasing the educational content on autonomic medicine in European medical and postgraduate curricula.

Beyond the womb: pontine hemorrhage’s impact on maternal and fetal outcomes: a case report from Nepal

Introduction: Strokes cause 37% of cardiovascular-related deaths in women, with 40% during delivery and 50% postpartum. Pontine hemorrhage, a rare cerebrovascular disease, can occur during pregnancy and postpartum, requiring complex diagnosis and management. Case presentation: A 33-year-old primipara female presented with headache, vomiting, and altered consciousness at 15 weeks and 5 days gestation. She had no history of head trauma, involuntary urine passage, cough, shortness of breath, palpitation, or per vaginal bleeding. Psychiatric and neurology consultations were conducted to address her symptoms. Discussion: Pontine hemorrhage is a rare condition affecting pregnant women, causing mild symptoms like vertigo, ataxia, and dysphagia. Our patient underwent an initial blood investigation with imaging of her brain (CT and MRI) to establish the diagnosis of pontine hemorrhage. It is believed to be caused by hormonal fluctuations, but studies have not proven it. Stroke during pregnancy is rare, with only 10% occurring during the antepartum period. Diagnosis requires a multidisciplinary approach with history, clinical examination, and radiological imaging like CT and MRI. Treatment involved antiplatelet therapy, which ensured favorable maternal and fetal outcomes for our patient. Conclusion: In summary, this case demonstrates the rare incidence of pontine hemorrhage during pregnancy. It highlights the diagnostic challenges and successful treatment with antiplatelet therapy, emphasizing the necessity for a comprehensive approach to ensure favorable maternal and fetal outcomes.

Stroke nurse-led intravenous thrombolytic therapy strategy for ischemic stroke based on timeline process: A quality improvement program from China

ObjectiveEarly thrombolytic therapy for ischemic stroke within the therapeutic window is associated with improved clinical outcomes. This study investigated whether optimizing intravenous thrombolytic (IVT) therapy strategies for stroke could reduce treatment delays. MethodsTo reduce delays in IVT therapy for ischemic stroke, a series of quality improvement measures were implemented at a tertiary hospital in Hangzhou, Zhejiang Province, from June 2021 to August 2023, which included developing a timeline process management system, forming a nurse-led stroke process management team, providing homogeneous training, standardizing the IVT therapy process for ischemic stroke, and introducing an incentive policy. During the pre- (from June 2021 to February 2022, group A) and post- (from March to November 2022, group B1; from December 2022 to August 2023, group B2 [implementation of an additional incentive policy]) of the implementation the strategy, the door-to-computed tomographic angiography(CTA) time (DCT), CTA time, neurology consultation to consent for IVT, CTA-to-needle time (CNT), and door-to-needle time (DNT), the percentage of people who underwent CTA within 20 min, 15 min, and 10 min and DNT within 60 min, 45 min, and 30 min were collected and compared. ResultsFollowing the implementation of the standardized IVT process management strategy for stroke, the DNT for group B1 and group B2 were 30 (24, 44) min and 31 (24, 41) min, respectively, both significantly lower than the 46 (38, 58) min in group A (P < 0.001); the median DCT were both 13 min in group B1 and B2 lower than 17min in group A (P < 0.001); the median CTA were 12 min in Group B1 and 9 min in Group B2 lower than 14 min in group A (P < 0.05); similar results were observed during the neurology consultation to obtain consent for IVT and CNT. Compared with group A, the proportion of DCT ≤ 20 min, 15 min, and 10 min was higher in groups B1 and B2 (P < 0.05), and the same result was observed at DNT ≤ 60 min, 45 min, and 30 min (P < 0.05). However, the additional incentive policy did not significantly differ between Group B2 and Group B1. ConclusionsOptimizing IVT therapy for ischemic stroke is a feasible approach to limit the DNT to 30 min in ischemic stroke, significantly reducing delays within the therapeutic window and increasing the number of patients meeting target time segments. Additionally, generating a timeline for the IVT therapy process by scanning positioning QR codes was a significant breakthrough in achieving the informatization of IVT quality management for stroke.

Transition from paediatric to adult neurological care: What do we know?

IntroductionHealthcare advances have allowed an increase in the survival of paediatric patients with neurological diseases. As a result, it is increasingly common to find these patients in adult neurology consultations. The aim of this study is to evaluate the current level of consensus on the transition of neuropaediatric patients among neurology and paediatric professionals in the Balearic Islands. Material and methodsWe conducted an observational, analytical, cross-sectional study through an anonymous questionnaire consisting of 27 questions, which was distributed to neurologists, paediatric neurologists, hospital paediatricians, and primary care paediatricians in the healthcare network of the Balearic Islands. It was developed using Google Forms and distributed by the competent professional societies. Consensus was considered to exist for answers with 70% or more agreement. ResultsResponses were received from 58 professionals; 46.6% were hospital paediatricians, 29.9% were neurologists, 13.8% were paediatric neurologists, and 13.8% were primary care paediatricians. Among other issues, consensus was observed on the need for a transition programme for patients with neurological diseases. No consensus was observed regarding the duration of the transition (P=.029) and how long simultaneous follow-up must last after the transfer (P=.09). ConclusionsDue to increased survival rates, there is a need to create transition programmes for paediatric patients with neurological diseases. In our study, more than 70% of professionals believed that it would be beneficial to create such programmes.

Diagnostic Challenges and Outcomes in Transient Loss of Consciousness: A Retrospective Analysis

Abstract Background Transient loss of consciousness (T-LOC) is a common presenting complaint, posing significant diagnostic challenges. This study explores outcomes for T-LOC. Methods Using the Hospital Inpatient Enquiry System, data on patients with T-LOC were collected at a large academic teaching hospital over six months, including demographics, length of stay (LOS), diagnostic tests, and discharge diagnoses. Results A total of 160 T-LOC patient visits were analysed, divided into three age cohorts: under 65 (n=66), 65-74 (n=38), and over 75 (n=56). Of the 94 patients aged over 65 (58.75% of the sample), mean age was 76.07 years; 47% were female. Diagnostics varied by age, with higher rates of computed tomography of the brain (87.23%) and lying-standing blood pressure (37.23%) in those over 65. Conversely, those over 65 were less likely to receive electrocardiograms (86.17% vs. 96.97%), telemetry (51.06% vs. 59.09%), magnetic resonance imaging of the brain (21.28% vs. 25.76%), transthoracic echocardiograms (14.89% vs. 25.76%), and exercise stress tests (3.19% vs. 10.61%) compared to those under 65. Carotid ultrasound and electroencephalography were infrequently performed across all age groups. Patients aged over 75 were most likely to have a diagnosis (78.57% vs 60.53% in 65-74 and 60.61% in under 65). Orthostatic hypotension was the most common diagnosis 8.51% (8/94) of those over 65. 33.13% (53/160) of patients had no diagnosis documented. LOS increased with age: averaging 6 days (range 1-19) for those under 64, 7.45 days (range 1-36) for those 65-74, and 9.09 days (range 1-64) for those over 75. Older adults were less likely to receive cardiology (19.15%) and neurology consultations (11.70%) compared to those under 65 (27.27% and 36.36%, respectively). Conclusion A considerable number of patients lacked a diagnosis, highlighting the diagnostic complexities of T-LOC. The development of a specialist syncope assessment pathway is underway to improve diagnostics, potentially reducing unnecessary tests and hospital stays.

Etiology and characteristics of non-aneurysmal thunderclap headache presenting to an acute setting

ObjectivesTo describe the characteristics and causes of non-aneurysmal thunderclap headache (TCH) and compare serious from benign underlying causes. MethodsRetrospective cohort study of consecutive adult patients with TCH presenting to a tertiary care academic medical center between 2010 and 2020. Aneurysmal subarachnoid hemorrhage cases were excluded. Cases were categorized into serious or benign; serious TCH was defined as any condition in which delayed diagnosis and treatment could result in neurological disability or death. Risk factors for serious TCH were analyzed. We adhere to standardized guidelines for reporting observational studies. ResultsA total of 932 patients presented with TCH. After exclusion of 393 patients with aneurysmal-type subarachnoid hemorrhage, 539 were included in the analysis. One-half (n = 275, 51.0 %) had a serious cause. Median age was 51 years, 69.0 % were female. Most frequent diagnoses were intracranial hemorrhage (n = 102, 18.9 %), reversible cerebral vasoconstriction syndrome (n = 97, 18.0 %), and idiopathic TCH (n = 102, 38.6 %). A multivariable logistic regression model for prediction of serious TCH included age, hypertension, migraines, recurrent TCH, level of consciousness and other clinical exam findings, and achieved an AUROC of 0.732. This score had a sensitivity of 79.9 % (95 % CI 73.5–83.5 %) for the identification of serious TCH. A 0.5-point increase in the risk score was associated with a 73 % increase in the odds of serious TCH (odds ratio 1.73, 95 % CI 1.53–1.95, p < 0.001). ConclusionOur study describes the relative frequency of presentation and etiologies among patients with TCH This score can aide clinicians in recognising patients with potentially serious cause of TCH, for whom additional imaging and neurological consultation is necessary.

Clinical characterization of women with migraine in neurology consultation

Introduction: migraine is a disease of the central nervous system that presents with recurrent headache, accompanied by autonomic symptoms and increased sensitivity to stimuli.Aim: to describe the demographic and clinical characteristics of women with migraine in a neurology consultation.Methodology: an observational, descriptive and cross- sectional study was carried out. Descriptive statistics were used to analyze the data and the chi square statistic was used to determine the possible association between qualitative variables.Results: a total of 40 patients were evaluated. The mean age was 30.7(SD=7.55) years. Patients whit white and black skin color predominated, 75% presented migraine episodes whithout aura. The patients had moderate to severe pain intensity with visual analog scale (VAS) score 7.70 (SD = 1.77), 100% presented severe disability with Migraine Disability Assessment (MIDAS) score 23.2 (SD= 1.91), 75% of the patients had a very severe headache impact with HIT-6 score 62.5 (SD = 4.40). There wasn’t association between pain intensity and family history of migraine (p=0,804).Conclusion: young women are the ones who most frecuently attend neurology consultations with great disability and the impact of headache

A Comparison of Treatment Practices for Newborn Seizure Management Across Level II and III Neonatal Intensive Care Units in the United States

BackgroundNeonatal seizures (NS) represent an important clinical manifestation among critically ill infants and are often the first sign of underlying brain injury. Early recognition and treatment are essential to reduce morbidity and mortality. The present study investigated the NS management and treatment approaches employed by level II/III neonatal intensive care units (NICUs) across the United States to identify areas of consensus and variability. MethodsPersonnel associated with level II/III NICUs were directly surveyed with an electronic questionnaire. Access to neurology specialists, on-site electroencephalography (EEG) monitoring, and use of antiseizure medications was directly queried. A total of 51 NICUs participated in this survey. ResultsTwenty-five percent of the surveyed NICUs reported having an established clinical practice pathway available for treating NS. Twenty-four percent endorsed having written guidelines that provided a formal definition for the concept of “neonatal seizures.” Although the majority of NICUs reported having phenobarbital available for rapid seizure management, most NICUs lacked access to additional antiseizure medications for treatment escalation. Twenty-four percent of the surveyed NICUs had no access to EEG monitoring available to them on-site. Daytime and overnight access to neurology consultants was limited and variable. ConclusionsFindings were consistent with a lack of equitable access for NS treatment. Areas of potential improvement include development and implementation of a protocol for rapidly treating NS that emphasizes enhanced access to EEG and rapid neurology consultation, acknowledging and improving upon resource limitations. These developments may eventually provide earlier detection, evaluation, and treatment of seizures in newborns, contributing to improved long-term outcomes.

Opinions and experience of neurologists and neurology trainees in Saudi Arabia on functional neurological disorders: a survey based study

BackgroundFunctional Neurological Disorder (FND) is commonly encountered in clinical practice, causing functional impairment and poor quality of life. As there is limited data from Saudi Arabia, our study aims to explore the experience and opinions of Saudi neurologists and neurology trainees regarding FND.MethodsIn our cross-sectional observational study, we included 100 neurology consultants and trainees. Data was collected using an online questionnaire from March to August 2023.ResultsA total of one hundred neurologists participated in the survey. Although 41% of physicians encountered FND patients on a weekly basis or more frequently, only 41.7% of trainees reported receiving dedicated lectures on FND. Furthermore, only 46% of respondents felt comfortable providing a clear explanation of the FND diagnosis to their patients. While the majority (64%) used the term “Functional Neurological Disorder” in medical documentation, only 43% used this term when communicating the diagnosis to patients, with the terminology varying widely. Clinicians emphasized that inconsistent and variable neurological examinations were key indicators raising diagnostic suspicion, which aligns with the recommended reliance on detailed clinical history and neurological examination. Lastly, 61% of physicians stated that their approach to patients with FND lacked a structured management plan.ConclusionOur study findings emphasize that FND is commonly encountered in clinical practice and reveal a significant lack of targeted education on FND for neurology trainees. Enhancing educational programs for both trainees and practicing neurologists on this prevalent neurological condition is essential for improving patient care and outcomes.

Correlation between semiautomated magnetic resonance imaging volumetry of the cingulate gyrus and interictal epileptiform discharge lateralization in dogs with idiopathic epilepsy.

Brain imaging suggests the involvement of the limbic system, particularly the cingulate gyrus (GC), in dogs with idiopathic epilepsy (IE). A correlation exists between the side of interictal epileptiform discharges (IEDs) and the volume of the ipsilateral GC (GCe) in dogs with IE. Dogs admitted to the neurological consultation (32 with epileptic seizures and 13 control) were included. This retrospective, blinded study followed the International Veterinary Epilepsy Task Force recommendations for diagnosing IE at the Tier III confidence level. The IE group included 18 and 14 dogs with IEDs in the left and right hemispheres, respectively (median age: 36 months, median weight: 19.5 kg), whereas the control group included 13 dogs (median age: 32 months, median weight: 20 kg). Whole-brain and GC-volumetric assessments were performed by a semiautomated method. In the control group, the volume of the GC was: left, from 743.63 to 1001.61 mm3, right, from 789.35 to 1015.86 mm3. In the study group, the volume of the GC was: left, from 720.88 to 1054.9 mm3 and right, from 566.29 to 987.77 mm3. In dogs with IE, GCe volume was significantly lower than the mean volume of the GC in the control group relative to total intracranial volume (TIV; P = .00044). Alterations in the volume of the GC provide insights into structural changes during IE. The use of semiautomatic volumetry provides an advantage by reducing the potential for human error.

Management of Severe Bilateral Symptomatic Internal Carotid Artery Stenosis: Case Report and Literature Review.

Multiple strategies for tandem severe carotid artery stenosis are reported: bilateral carotid artery endarterectomy (CEA), bilateral carotid artery stenting (CAS), and hybrid procedures (CEA and CAS). The management is controversial, considering the reported high risk of periprocedural stroke, hemodynamic distress, and cerebral hyperperfusion syndrome. We present the case of a 64-year-old patient with severe symptomatic bilateral internal carotid artery stenosis (95% stenosis on the left internal carotid artery with recent ipsilateral watershed anterior cerebral artery-medial cerebral artery (ACA-MCA) and medial cerebral artery-posterior cerebral artery (MCA-PCA) ischemic strokes and 90% stenosis on the right internal carotid artery with chronic ipsilateral frontal ischemic stroke) managed successfully with staged CEA within a 3-day interval. The patient had a history of coronary angioplasty and stenting. Strategies for brain protection included shunt placement after the evaluation of carotid stump pressure, internal carotid backflow, and near-infrared spectroscopy. A collagen and silver-coated polyester patch was used to complete the endarterectomy using a 6.0 polypropylene continuous suture in both instances. Management also included neurological consults after extubation, dual antiplatelet therapy, head CT between the two surgeries, myocardial ischemia monitoring, and general anesthesia. Staged CEA with a small time interval between surgeries can be an option to treat tandem symptomatic carotid artery stenosis in highly selected patients. The decision should be tailored according to the patient's characteristics and should also be made by a cardiology specialist, a neurology specialist, and an anesthesia and intensive care physician.

Multiple Cerebral Cavernous Malformation: An Unusual Cause of Vertigo.

Cerebral cavernous malformation (CM) is a rare benign vascular lesion of the brain, accounting for only 0.3-0.5% incidence in the population. Among them, only a small portion of the patients have multiple lesions (3-33%). While most lesions are asymptomatic, some patients present with seizures and hemorrhagic events. We present an atypical case of multiple cerebral CM in a patient who presented with vertigo. He did not have apparent neurological signs and symptoms until it was detected through imaging studies. His MRI showed multiple CM, with the largest lesion located in the cerebellopontine angle. A neurological consult was obtained and the patient opted for conservative treatment. He was discharged well on medications and was under active monitoring by both the neurosurgery and otorhinolaryngology teams. Intracranial cavernoma can present as vertigo without classic neurological manifestations. Any atypical presentations should alert the physician to perform further imaging to rule out sinister causes in the brain. To date, there is no reported case of intracranial cavernoma presenting as vertigo in the literature.

Provider Impressions of Inpatient Teleneurology Consultation.

Teleneurology usage has increased during the severe acute respiratory syndrome coronavirus 2 pandemic. However, studies evaluating physician impressions of inpatient teleneurology are limited. We implemented a quality improvement initiative to evaluate neurologists' impression following individual inpatient teleneurology consultation at a satellite hospital of a large academic center with no in-person neurology coverage. A REDCap survey link was embedded within templates used by neurologists for documentation of inpatient consultations to be completed immediately after encounters. All teleneurology encounters with completed surveys at a single satellite hospital of the University of Pennsylvania Health System Neurology Department between May 10, 2021, and August 14, 2022, were included. Individual patient-level and encounter-level data were extracted from the medical record. A total of 374 surveys (response rate of 54.05%) were completed by 19 neurologists; 341 questionnaires were included in the analysis. Seven neurologists who specialized as neurohospitalists completed 231 surveys (67.74% of total surveys completed), while 12 non-neurohospitalists completed 110 (32.36%). The history obtained was rated as worse (14%) or the same (86%) as an in-person consult; none reported the history as better than nonteleneurology encounters. The physician-patient relationship was poor or fair in 25% of the encounters and good or excellent in 75% of visits. The overall experience was judged to be worse than in-person consultation in 32% of encounters, the same in 66%, and better in 2%. Fifty-one percent of providers responded that there were elements of the neurologic examination that might have changed their assessment and plan of care if performed in-person. Encounters with peripheral or neuromuscular-related chief complaints had the most inadequate examinations and worse overall experiences, while the most positive impressions of these clinical experiences were observed among seizure-related chief complaints. Determining best practices for inpatient teleneurology should consider the patient chief complaint to use teleneurology in scenarios with the highest likelihood of a positive experience. Further efforts should be made to the patient experience and to improve the remote examination to enhance the applicability of teleneurology to the full spectrum of inpatient neurologic consultations.

A Case Report of Worsening Alzheimer’s Disease Symptoms after COVID-19 Infection That Were Treated with Yigan-san-gami

Introduction: In this case report, we describe the clinical effectiveness of Yigan-san-gami in improving symptoms in a patient with worsening Alzheimer’s dementia after COVID-19 infection.Case presentation: Symptoms of dementia worsened in a patient with Alzheimer’s disease after COVID-19 infection. Western medicines were added following neurological consultation. However, there was no medicinal effect. The patient was treated with Korean medicine (Yigan-san-gami) three times a day. We used daily charts, the Korean Mini-Mental State Examination-2 (K-MMSE-2), Clinical Dementia Rating (CDR), and Short Version Geriatric Depression Scale (SGDS) to assess the patient’s symptoms. Cognitive decline and behavioral and psychological symptoms of dementia (BPSD) improved following the treatment with Yigan-san-gami.Conclusion: The results suggest that Yigan-san-gami may be effective in improving symptoms of Alzheimer’s disease that worsen after COVID-19 infection.

P.069 Development of a streamlined multi-disciplinary care pathway for compression neuropathies

Background: Care for patients with compression neuropathies (carpal tunnel syndrome, ulnar neuropathy) is often fragmented, uncoordinated, and slow. Patients go through multiple steps (neurology consultation, nerve testing, ultrasound, splints, injection, surgical opinion, surgery) with waits between each step. We used a Value-Based Health Care (VBHC) model to develop a multidisciplinary clinic with a novel care pathway. Methods: A Shared Care initiative supported the development of an Integrated Practice Unit (IPU). Key multidisciplinary team members were identified. Participants attended a curated three part VBHC workshop. Process mapping enabled identification of efficiencies. Results: 14 team members participated in the workshops. Condition specific outcome measures were identified (Boston CTS measure, 10-point touch, MRC strength and pain scale) and will be collected longitudinally. Criteria and clinical pathways were developed for mild, moderate, and severe carpal tunnel syndrome. Resource materials for patients and providers were developed. Conclusions: A VBHC framework supported development of a novel clinic for compression neuropathy. Responsibility for the full cycle of care rests with the IPU. Systematically tracking functional outcome measures enables quality improvement. By streamlining the patient journey and substantially reducing wait times between steps, the new care pathway reduces complexity and improve outcomes. Evaluation of impact if this new clinical model is ongoing.

Clinical Characterization of Veterans With Alzheimer Disease by Disease Severity in the United States.

We aimed to examine the clinical characteristics of US veterans who underwent neurocognitive test score-based assessments of Alzheimer disease (AD) stage in the Veterans Affairs Healthcare System (VAHS). Test dates for specific stages of AD were referenced as index dates to study behavioral and psychological symptoms of dementia (BPSD) and other patient characteristics related to utilization/work-up and time to death. We identified veterans with AD and neurocognitive evaluations using the VAHS Electronic Health Record (EHR). Anxiety and sleep disorders/disturbances were the most documented BPSDs across all AD severity stages. Magnetic resonance imaging, neurology and psychiatry consultations, and neuropsychiatric evaluations were slightly higher in veterans with mild AD than in those at later stages. The overall average time to death from the first AD severity record was 5 years for mild and 4 years for moderate/severe AD. We found differences in clinical symptoms, healthcare utilization, and survival among the mild, moderate, and severe stages of AD. These differences are limited by the low documentation of BPSDs among veterans with test score-based AD stages. These data support the hypothesis that our cohorts represent coherent subgroups of patients with AD based on disease severity.

Integration of the expanded disability status scale with ambulation, visual and cognitive tests.

The Expanded Disability Status Scale (EDSS) is usually calculated through a neurological examination with self-reported performance. This may lead to incorrect assessment of Functional System scores (FSs). Aim of our study was to estimate the difference between EDSS obtained during routine visits, or after specific tests. We enrolled 670 MS patients that underwent a regular neurology consultation, and visual evaluation using optotype tables, ambulation evaluation with a rodometer, and cognitive assessment with the Brief International Cognitive assessment for MS (BICAMS). We calculated a new integrated EDSS (iEDSS) using the refined values of the FS and compared it to the standard EDSS. Visual, cerebral and ambulation FSs were significantly higher compared with the self-reported counterpart [+ 1.169 (95%CI 1.077, 1.262; p < 0.001), + 0.727 (95%CI 0.653, 0.801; p < 0.001) and + 0.822 (95%CI 0.705, 0.939; p < 0.001), respectively]. Mean iEDSS was higher than EDSS (+ 0.642; p < 0.001). Visual acuity tests worsened the EDSS in 31% of cases, cognitive tests in 10%, ambulation measurement in 35%, all three measurements in 59% of cases. Objective measurement of FSs results in a more accurate EDSS score in almost two-thirds of cases. This could lead to a more thorough evaluation of patients in the transition or progressive phase.

Bobble Head Doll Syndrome Revealing a Suprasellar Arachnoid Cyst : Case Report

Introduction Bobble head doll syndrome (BHDS) is a rare neurological syndrome that appears in childhood. It is characterized by abnormal movements of the head, most commonly in an up-and-down motion ("yes yes") and rarely in the horizontal plane ("no no"). We report a case of BHDS revealing a large suprasellar arachnoid cyst. Observation A 6-year-old child was brought by his parents to a neurology consultation for abnormal head movements, which most frequently occurred in an upward and downward direction, but disappeared during sleep. These abnormal movements had been progressively worsening over the course of approximately one year. Clinical examination revealed a decrease in visual acuity in both eyes, with papillary hyperemia on fundoscopy and discreet ataxia in walking. Magnetic resonance imaging (MRI) revealed a compressive suprasellar arachnoid cyst with passive biventricular hydrocephalus. Surgical treatment with neuro-endoscopy led to a remarkable regression of abnormal head movements and ataxia in the immediate postoperative period, with complete disappearance in the long term. Conclusion Bobble head doll syndrome is a potentially "curable" entity, and diagnosis is provided by cerebral MRI.

Neurological aspects of HTLV-1 infection: symptoms in apparently asymptomatic carriers.

Human T-lymphotropic virus type 1 (HTLV-1) is classically associated with the HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), although the mechanisms of this neurological disorder remain unclear. In addition, some patients who develop "minor" neurological signs that do not meet diagnostic criteria for HAM/TSP are classified as asymptomatic carriers. This study aims to demonstrate the neurological symptoms of Brazilian patients living with HTLV-1 classified as not-HAM.TSP.This observational study evaluated patients treated in an HTLV reference center in Bahia, Brazil, between February 2022 and July 2023. The data were obtained through the analysis of medical records and neurological consultation. Those individuals classified as HAM/ TSP were excluded from this study. 74 patients were submitted to a careful neurological evaluation: 23 HAM/TSP, 22 were classified with intermediate syndrome (IS), and 29 were oligosymptomatic. Self-reported symptoms were significantly more common in the IS group, including urinary symptoms such as nocturia, urgency, incontinence, dysuria, weakness, paresthesia, lumbar pain, xerostomia, and xerophthalmia. Physical examination findings consistent with reduced vibratory and tactile sensitivity were more common in the IS group (p = 0.017 and p = 0.013). Alterations in the V and VIII cranial nerves were present in both groups. HTLV-1 can lead to the development of important neurological signs and symptoms in apparently asymptomatic individuals. This data highlights the need for more research into the neurological aspects of HTLV-1 infection and emphasizes the importance of early diagnosis, treatment, and support for individuals living with this virus.
