RESUMO
The relationship between spirituality and religiosity and their impact on mental health is intricate and underexplored. This exploratory review aims to elucidate the distinct effects of these constructs, highlighting their contributions to psychological well-being and clinical practices. By dissecting the impacts of spirituality and religiosity on mental health, the study focuses on their individual and combined roles in shaping therapeutic approaches and theoretical understandings in the field. A literature review was conducted using PubMed, focusing on articles discussing spirituality, religiosity, and their intersection with mental health and psychopathology. Out of 312 identified articles, 69 peer-reviewed articles were included after screening for relevance. The results indicate that spirituality and religiosity significantly influence mental health yet are often conflated, leading to research inconsistencies and clinical challenges. Spirituality, as a broad and individualistic pathway, enhances personal well-being and resilience, often transcending organized religious practices. In contrast, religiosity, with its structured community support, sometimes imposes constraints that exacerbate stress under specific doctrinal pressures. Neurobiological evidence suggests that both constructs interact with cognitive processes and brain function, influencing emotional regulation and stress response. The study concludes that distinguishing between spirituality and religiosity is essential for precise academic discourse and effective clinical practice. This differentiation allows for more personalized therapeutic approaches, accommodating an individual's spiritual and religious contexts. The authors propose a refined framework for future research and therapeutic applications to be sensitive to the nuanced experiences of individuals and to better tailor interventions in clinical settings.
RESUMO
INTRODUCTION: Multiple Sclerosis (MS) can affect the ability to perform complex tasks such as driving. The Expanded Disability Status Scale (EDSS) overlooks cognitive deficits crucial for driving. We investigated the relationship between the Multiple Sclerosis Functional Composite (MSFC), which includes cognitive assessment, and EDSS in relation to driving performance. METHODS: This exploratory study involved 30 MS patients (mean EDSS 2.4 ± 2.0) and 15 healthy controls. We correlated the results of the EDSS, MSFC, and driving performance tests, namely the Two-Hand Coordination Test (2HAND) and the Speed Anticipation Reaction Test (SART). RESULTS: Patients did not differ from the healthy controls regarding age, sex, and driving experience. However, they exhibited lower mean Z-scores in MSFC, particularly in motor domains, but not in cognitive function. The mean Z-score for the 25-foot Walk test was -0.42 in patients compared to -0.04 in controls. For the 9-hole Peg Test, it was 0.17 in patients versus 1.47 in controls. Patients had a mean total error time of 19.7â¯seconds for both hands in the 2HAND test, compared to 7.7â¯seconds in controls. In MS patients, the MSFC and EDSS significantly correlated with SART and 2HAND components. While upper limb function (9-HPT) did not correlate with 2HAND, cognitive function (PASAT) did correlate with the number of 2HAND errors, indicating that cognitive dysfunction impacts driving performance more than physical dysfunction. CONCLUSION: The MSFC may provide valuable insights into the driving abilities of MS patients, potentially offering advantages over the EDSS in predicting driving performance. Further research with larger, more diverse populations across various driving environments is necessary to validate these findings.

Alzheimer's disease (AD), the most common cause of dementia, is a complex and multifactorial condition without cure at present. The latest treatments, based on anti-amyloid monoclonal antibodies, have only a modest effect in reducing the progression of cognitive decline in AD, whereas the possibility of preventing AD has become a crucial area of research. In fact, recent studies have observed a decrease in dementia incidence in developed regions such as the US and Europe. However, these trends have not been mirrored in non-Western countries (Japan or China), and the contributing factors of this reduction remain unclear. The Lancet Commission has delineated a constrained classification of 12 risk factors across different life stages. Nevertheless, the scientific literature has pointed to over 200 factors-including sociodemographic, medical, psychological, and sociocultural conditions-related to the development of dementia/AD. This narrative review aims to synthesize the risk/protective factors of dementia/AD. Essentially, we found that risk/protective factors vary between individuals and populations, complicating the creation of a unified prevention strategy. Moreover, dementia/AD explanatory mechanisms involve a diverse array of genetic and environmental factors that interact from the early stages of life. In the future, studies across different population-based cohorts are essential to validate risk/protective factors of dementia. This evidence would help develop public health policies to decrease the incidence of dementia.
RESUMO
Background: Dengue neuro-infection can present with symptoms ranging from mild to severe. Atypical presentations, such as expanded dengue syndrome, pose diagnostic and therapeutic challenges. Neuroimaging findings, particularly the "double-doughnut" sign on brain magnetic resonance imaging (MRI), have emerged as one of the most valuable aids in diagnosing complex cases of central nervous system infection by dengue virus. Case Presentation: We report the case of a 35-year-old female from rural West Bengal, India, with expanded dengue syndrome. The patient presented with fever, headaches, body aches, and sudden disorientation over minutes, which progressed to a coma. Neurological examination revealed profound unconsciousness and nuchal rigidity. Laboratory findings were consistent with dengue infection, including altered liver and pancreatic enzyme levels. The diagnosis was facilitated by identifying the "double-doughnut" sign on the brain MRI, which suggested dengue encephalitis. This finding and clinical and serological evidence guided the treatment strategy. Discussion: The "double-doughnut" sign, though not exclusive to dengue encephalitis, proved crucial in this case, aiding in differentiating from other causes of encephalitis. Recognition of this sign can be pivotal in diagnosing expanded dengue syndrome, facilitating timely and appropriate intervention, and improving patient outcomes. This case also underscores the importance of considering dengue in the differential diagnosis of encephalitis, especially in endemic areas. Also, this case's excellent outcome (both clinically and radiologically) was noteworthy.
RESUMO
INTRODUCTION: Seizure disorders have often been found to be associated with corpus callosum injuries, but in most cases, they remain undiagnosed. Understanding the clinical, electrographic, and neuroradiological alternations can be crucial in delineating this entity. OBJECTIVE: This systematic review aims to analyze the effects of corpus callosum injuries on seizure semiology, providing insights into the neuroscientific and clinical implications of such injuries. METHODS: Adhering to the PRISMA guidelines, a comprehensive search across multiple databases, including PubMed/Medline, NIH, Embase, Cochrane Library, and Cross-ref, was conducted until September 25, 2023. Studies on seizures associated with corpus callosum injuries, excluding other cortical or sub-cortical involvements, were included. Machine learning (Random Forest) and deep learning (1D-CNN) algorithms were employed for data classification. RESULTS: Initially, 1250 articles were identified from the mentioned databases, and additional 350 were found through other relevant sources. Out of all these articles, 41 studies met the inclusion criteria, collectively encompassing 56 patients The most frequent clinical manifestations included generalized tonic-clonic seizures, complex partial seizures, and focal seizures. The most common callosal injuries were related to reversible splenial lesion syndrome and cytotoxic lesions. Machine learning and deep learning analyses revealed significant correlations between seizure types, semiological parameters, and callosal injury locations. Complete recovery was reported in the majority of patients post-treatment. CONCLUSION: Corpus callosum injuries have diverse impacts on seizure semiology. This review highlights the importance of understanding the role of the corpus callosum in seizure propagation and manifestation. The findings emphasize the need for targeted diagnostic and therapeutic strategies in managing seizures associated with callosal injuries. Future research should focus on expanding the data pool and exploring the underlying mechanisms in greater detail.

Background: Hypercalcemia-induced posterior reversible encephalopathy syndrome (PRES) is a rare entity primarily associated with iatrogenic vitamin D/calcium overdose, malignancy, or, infrequently, primary hyperparathyroidism. Case Report: We present a novel case of an adult male from rural India who experienced recurrent acute pancreatitis caused by hypercalcemia with concurrent manifestation of PRES. Diagnostic evaluation revealed markedly elevated serum calcium levels and parathyroid hormone concentrations, consistent with primary hyperparathyroidism. Imaging studies identified a parathyroid adenoma near the right thyroid lobe, subsequently surgically excised. Discussion: This case underscores the importance of considering primary hyperparathyroidism as an underlying cause of PRES, especially in the absence of acute arterial hypertension or autonomic dysfunction. Early recognition and intervention are essential in mitigating the morbidity and mortality of PRES.

BACKGROUND AND AIMS: Acute onset de novo movement disorder is an increasingly recognized, yet undereported complication of diabetes. Hyperglycemia can give rise to a range of different movement disorders, hemichorea-hemiballism being the commonest. This article delves into the current knowledge about this condition, its diverse presentations, ongoing debates regarding its underlying mechanisms, disparities between clinical and radiological findings, and challenges related to its management. METHODS: PubMed and Google Scholar were searched with the following key terms- "diabetes", "striatopathy", "hyperglycemia", "striatum", "basal ganglia", "movement disorder", "involuntary movement". Case reports, systematic reviews, meta-analysis, and narrative reviews published in English literature related to the topic of interest from January 1, 1950, to October 20, 2023, were retrieved. The references cited in the chosen articles were also examined, and those considered relevant were included in the review. RESULTS: Diabetic striatopathy is the prototype of movement disorders associated with hyperglycemia with its characteristic neuroimaging feature (contralateral striatal hyperdensitity on computed tomography or hyperintensity on T1-weighted magnetic resonance imaging). Risk factors for diabetic striatopathy includes Asian ethnicity, female gender, prolonged poor glycemic control, and concurrent retinopathy. Several hypotheses have been proposed to explain the pathophysiology of movement disorders induced by hyperglycemia. These hypotheses are not mutually exclusive; instead, they represent interconnected pathways contributing to the development of this unique condition. While the most prominent clinical feature of diabetic striatopathy is a movement disorder, its phenotypic expression has been found to extend to other manifestations, including stroke, seizures, and cognitive and behavioral symptoms. Fortunately, the prognosis for diabetic striatopathy is generally excellent, with complete resolution achievable through the use of anti-hyperglycemic therapy alone or in combination with neuroleptic medications. CONCLUSION: Hyperglycemia is the commonest cause of acute onset de novo movement disorders presenting to a range of medical specialists. So, it is of utmost importance that the physicians irrespective of their speciality remain aware of this clinical entity and check blood glucose at presentation before ordering any other investigations. Prompt clinical diagnosis of this condition and implementation of intensive glycemic control can yield significant benefits for patients.

BACKGROUND: Cognitive dysfunction is regarded as one of the most severe aftereffects following coronavirus disease 2019 (COVID-19). Eye movements, controlled by several brain areas, such as the dorsolateral prefrontal cortex and frontal-thalamic circuits, provide a potential metric for assessing cortical networks and cognitive status. We aimed to examine the utility of eye movement measurements in identifying cognitive impairments in long COVID patients. METHODS: We recruited 40 long COVID patients experiencing subjective cognitive complaints and 40 healthy controls and used a certified eye-tracking medical device to record saccades and antisaccades. Machine learning was applied to enhance the analysis of eye movement data. RESULTS: Patients did not differ from the healthy controls regarding age, sex, and years of education. However, the patients' Montreal Cognitive Assessment total score was significantly lower than healthy controls. Most eye movement parameters were significantly worse in patients. These included the latencies, gain (computed as the ratio between stimulus amplitude and gaze amplitude), velocities, and accuracy (evaluated by the presence of hypermetric or hypometria dysmetria) of both visually and memory-guided saccades; the number of correct memory saccades; the latencies and duration of reflexive saccades; and the number of errors in the antisaccade test. Machine learning permitted distinguishing between long COVID patients experiencing subjective cognitive complaints and healthy controls. CONCLUSION: Our findings suggest impairments in frontal subcortical circuits among long COVID patients who report subjective cognitive complaints. Eye-tracking, combined with machine learning, offers a novel, efficient way to assess and monitor long COVID patients' cognitive dysfunctions, suggesting its utility in clinical settings for early detection and personalized treatment strategies. Further research is needed to determine the long-term implications of these findings and the reversibility of cognitive dysfunctions.

INTRODUCTION: Fatigue is one of the most disabling symptoms of multiple sclerosis (MS), and effective treatments are lacking. Amantadine is one of the most used treatments, although its efficacy is under debate. Transcranial magnetic stimulation (TMS) is a promising intervention that has shown positive effects in some preliminary investigations. We aim to investigate the effect of 6 weeks of amantadine and/or TMS in fatigue due to MS. METHODS AND ANALYSIS: The study is a national, multicentre, phase 3, randomised, double-blind, cross-over, placebo-controlled and sham-controlled clinical trial. Adult patients with relapsing-remitting MS, Expanded Disability Status Scale score of 1.5-4.5 and Fatigue Severity Score>4 are eligible for the trial. Participants will be randomised to one of the sequences of the study. Each sequence consists of four periods of 6 weeks of treatment and three washout periods of 12-18 weeks. All patients will receive all the combinations of therapies. The primary outcome is the Modified Fatigue Impact Scale. The secondary outcomes are the Symbol Digit Modalities Test (cognition), Beck Depression Inventory-II (depressive symptoms) and Short-Survey 12 (quality of life). Safety and cost-effectiveness will also be evaluated. An exploratory substudy including MRI and blood biomarkers will be conducted. ETHICS AND DISSEMINATION: The study is approved by the Ethics Committee of the Hospital Clinico San Carlos and the Spanish Agency of Medications and Medical Devices. All study findings will be published in scientific peer-reviewed journals and presented at relevant scientific conferences. TRIAL REGISTRATION NUMBER: EudraCT 2021-004868-95; NCT05809414.
