Teleneurology and Artificial Intelligence in Clinical Practice.

ABSTRACT: As teleheath becomes integrated into the practice of medicine, it is important to understand the benefits, limitations, and variety of applications. Telestroke was an early example of teleneurology that arose from a need for urgent access to neurologists for time-sensitive treatments for stroke. It made a scarce resource widely available via video conferencing technologies. Additionally, applications such as outpatient video visits, electronic consultation (e-consult), and wearable devices developed in neurology, as well. Telehealth dramatically increased during the COVID-19 pandemic when offices were closed and hospitals were overwhelmed; a multitude of both outpatient and inpatient programs developed and matured during this time. It is helpful to explore what has been learned regarding the quality of telehealth, disparities in care, and how artificial intelligence can interact with medical practices in the teleneurology context.

Forensic Neurology and the Role of Neurologists in Forensic Evaluations.

Forensic psychiatrists may be asked to opine on neurological evidence or neurological diseases outside the scope of their expertise. This article discusses the value of involving experts trained in behavioral neurology in such cases. First, we describe the field of behavioral neurology and neuropsychiatry, the subspecialty available to both neurologists and psychiatrists focused on the behavioral, cognitive, and neuropsychiatric manifestations of neurological diseases. Next, we discuss the added value of behavioral neurologists in forensic cases, including assisting in the diagnostic evaluation for complex neuropsychiatric diseases, using expertise in localization to provide a strong scientific basis for linking neurodiagnostic testing to relevant neuropsychiatric symptoms, and assisting in relating these symptoms to the relevant legal question in cases where such symptoms may be less familiar to forensic psychiatrists, such as frontal lobe syndromes. We discuss approaches to integrating behavioral neurology with forensic psychiatry, highlighting the need for collaboration and mentorship between disciplines. Finally, we discuss several forensic cases highlighting the additional value of experts trained in behavioral neurology. We conclude that forensic psychiatrists should involve behavioral neurology experts when encountering neurological evidence that falls outside their scope of expertise, and the need for further cross-disciplinary collaboration and training.

Forensic Neurology and the Role of Neurologists in Forensic Evaluations.

There is a clear need for experts with the requisite knowledge and experience to offer medicolegal opinions pertaining to various neuropsychiatric conditions. There is also an important distinction between clinical and medicolegal roles, and the need for training and expertise applicable to forensic assessment. But there remain few available experts with credentials spanning neuropsychiatry and forensic assessment. This creates a dilemma whereby parties involved in litigation featuring neuropsychiatric illness or injury are frequently forced to choose between experts with either knowledge and skills applicable to neuropsychiatric conditions or experts with skills and experience applicable to forensic assessment. Either choice introduces risk. Whether flawed medicolegal opinions are a consequence of deficient medical knowledge or an inadequate forensic evaluation process, the result remains the same, with triers of fact potentially being exposed to problematic testimony. There is, however, a more fundamental problem that implicates patient care more broadly: spurious dichotomies created by the historical segregation of psychiatry and neurology. Optimizing clinical care for patients with neuropsychiatric conditions, improving medical education in support of such care, and enabling forensic neuropsychiatric assessment must then start with more proactive efforts to reintegrate psychiatry and neurology.

Improving Access to Autism Evaluation: A Coordinated Developmental-Behavioral Pediatrics and Pediatric Neurology Diagnostic Pathway.

A shortage of board-certified developmental-behavioral pediatricians generates a bottleneck for children and families who seek autism diagnostic services. Wait time for autism evaluation commonly exceeds a year. To improve access, clinicians developed a coordinated Developmental-Behavioral Pediatrics and Pediatric Neurology autism diagnostic pathway. For a subset of children referred to neurology clinic, pediatric neurologists completed the medical part of an autism evaluation and Knights of Columbus Developmental Center psychologists or speech-language pathologists completed developmental assessments. Forty-four autism diagnostic evaluations completed through this coordinated pathway over the course of six months had shortened wait time [mean=50.89 days; range 3 to 184 days; median= 48.50 day]. Parents reported satisfaction with the autism evaluation and resources navigation process. Sustainability and scalability efforts are discussed.

Forensic Neurology: Practice Considerations and Training Opportunities.

Neurologic evidence, including MRI, PET, and EEG, has been introduced in more than 2,800 criminal cases in the past decade, including 12% of all murder trials and 25% of death penalty trials, to argue whether neurologic diseases are present, contribute to criminal behavior, and ultimately whether the defendant is less criminally responsible, competent to stand trial, or should receive a reduced punishment for his or her crime. Unfortunately, neurologists are often not involved in these criminal cases despite being the medical specialty with the most relevant training and expertise to address these issues for the court. Reasons for the absence of neurologists in criminal cases include a lack of awareness from lawyers, judges, and other expert witnesses on the value of including neurologists in forensic evaluations, and the lack of experience, training, and willingness of neurologists to work as expert witnesses in criminal cases. Here, we discuss forensic neurology, a field bridging the gap between neurology, neuroscience, and the law. We discuss the process of performing forensic evaluations, including answering 3 fundamental questions: the neurologic diagnostic question, the behavioral neurology/neuropsychiatry question, and the forensic neurology question. We discuss practical aspects of performing forensic expert witness work and important ethical differences between the neurologist's role in treatment vs forensic settings. Finally, we discuss the currently available pathways for interested neurologists to receive additional training in forensic assessments.

[Evaluation of the management of hypertension among stroke patients in a neurology department of Côte d'Ivoire]. / Évaluation de la prise en charge de l'hypertension artérielle après un accident vasculaire cérébral dans un service de neurologie en Côte-d'Ivoire.

Introduction: Reducing blood pressure after stroke is important to prevent recurrent stroke, but we have no data about the control of blood pressure in our context. The purpose of this study was to assess management of hypertension among post-stroke patients in a neurology department. Method: It was a retrospective study involving hypertensive stroke patients. They were followed up at 1, 3, 6 and 12 months after discharge. Results: 141 patients fulfilled the inclusion criteria. The mean age was 61 years. Almost all patients (94.3%) received a dual antihypertensive therapy combining mainly an ACE inhibitor and a diuretic (70.2%). During follow-up, only 76 patients were assessed at M1, 50 at M3, 44 at M6 and 42 at M12. The average monthly cost of antihypertensive treatment was 13,771 CFA francs (21 euros). Non-adherence to antihypertensive medication were mostly noted in widows, patients without occupation, those with low education and no health insurance. At one year, blood pressure was controlled in 80% of the 42 patients still present. Non-control of blood pressure was related to poor therapeutic compliance (p<0.05). Conclusion: This study highlights follow-up issues in hypertensive post-stroke patients with a high number of lost to follow-up. Blood pressure was controlled in patients who were regularly followed and adherent to antihypertensive treatment.

Recientemente, un grupo liderado por la Multiple Sclerosis Data Alliance ha desarrollado un core data set para la recolección de datos del mundo real en EM a nivel global. Nuestro objetivo ha sido adaptar y consensuar este conjunto de datos globales a las necesidades de América Latina para que pueda ser implementado por los registros ya desarrollados y en proceso de desarrollo en la región. Material y métodos. Se conformó un grupo de trabajo regionalmente y se adaptó el core data set creado globalmente (proceso de traducción al español, incorporación de variables regionales y consenso sobre variables que se iban a utilizar). El consenso se obtuvo a través de la metodología Delphi remoto de ronda de cuestionarios y discusión a distancia de las variables del core data set. Resultados: Veinticinco profesionales de América Latina llevaron adelante el proceso de adaptación entre noviembre de 2022 y julio de 2023. Se estableció un acuerdo sobre un core data set de nueve categorías y 45 variables, versión 2023, con la sugerencia de implementarlo en registros desarrollados o en vías de desarrollo y cohortes de EM en la región. Conclusión: El core data set busca armonizar las variables recolectadas por los registros y las cohortes de EM en América Latina con el fin de facilitar dicha recolección y permitir una colaboración entre fuentes. Su implementación facilitará la recolección de datos de vida real y la colaboración en la región.(AU)

Introduction: The primary objective of the core data set is to reduce heterogeneity and promote harmonization among data sources in EM, thereby reducing the time needed to execute real life data collection efforts. Recently, a group led by the Multiple Sclerosis Data Alliance has developed a core data set for collecting real-world data on multiple sclerosis (MS) globally. Our objective was to adapt this global data set to the needs of Latin America, so that it can be implemented by the registries already developed and in the process of development in the region. Material and methods: A working group was formed regionally, the core data set created globally was adapted (translation process into Spanish, incorporation of regional variables and consensus on variables to be used). Consensus was obtained through the remote Delphi methodology of a round of questionnaires and remote discussion of the core data set variables. Results: A total of 25 professionals from Latin America carried out the adaptation process between November 2022 and July 2023. Agreement was established on a core data set of nine categories and 45 variables, version 2023 to suggest its implementation in developed or developing registries, and MS cohorts in the region. Conclusion: The core data set seeks to harmonize the variables collected by registries and cohorts in MS in Latin America in order to facilitate said collection and allow collaboration between sources. Its implementation will facilitate real life data collection and collaboration in the region.(AU)

Cronología de la investigación sobre la dinámica cerebral de Justo Gonzalo / Chronology of Justo Gonzalo’s research on brain dynamics

Introducción: El neurocientífico español Justo Gonzalo y Rodríguez-Leal (1910-1986) investiga la organización funcional de la corteza cerebral durante más de cuatro décadas. Sus hallazgos le llevan a formular una teoría neurofisiológica basada en las leyes de la excitabilidad nerviosa, que denomina dinámica cerebral. En el presente trabajo se expone de forma cronológica cómo surgen las principales ideas sobre las que se articula.Desarrollo: En 1939 Gonzalo observa los denominados fenómenos de acción dinámica: desfasamiento, facilitación y repercusión cerebral. Le siguen dos principios: efecto cerebral de la lesión según la magnitud y posición (1941), y organización sensorial, según un desarrollo espiral (1947). Paralelamente, caracteriza lo que llama el síndrome central de la corteza cerebral. En la década de los cincuenta desarrolla los conceptos de gradiente cortical, similitud y alometría. En contraposición a las concepciones modulares de la corteza cerebral, en las que una región es responsable de una función, Gonzalo expresa que ‘los gradientes corticales dan la localización de los sistemas mientras la similitud y alometría revelan su trama funcional’.Conclusiones: La teoría de dinámica cerebral se articula en dos etapas. La primera (de 1938 a 1950) se caracteriza por una importante base clínica con observación de nuevos fenómenos y formulación de nuevos conceptos. La segunda (de 1950 a 1960) incluye la introducción de conceptos de mayor alcance, como el gradiente funcional cortical, y leyes de alometría que se basan en un cambio de escala. Actualmente, varios autores consideran que el concepto de gradiente es clave para entender la organización cerebral.(AU)

Introduction: The Spanish neuroscientist Justo Gonzalo y Rodríguez-Leal (1910-1986) investigated the functional organisation of the cerebral cortex over more than four decades. His findings led him to formulate a neurophysiological theory based on the laws of nervous excitability, which he called brain dynamics. This paper presents in chronological order how the main ideas on which it is based arose.Development: In 1939, Gonzalo observed the phenomena of dynamic action: asynchrony or disaggregation, facilitation and cerebral repercussion. This was followed by two principles: the cerebral effect of lesions according to their magnitude and position (1941), and spiral development of the sensory field (1947). At the same time, he characterised what he called the central syndrome of the cerebral cortex. In the 1950s he developed the concepts of the cortical gradient, similarity and allometry. In contrast to modular conceptions of the cerebral cortex, in which one region is responsible for one function, Gonzalo argued that ‘cortical gradients provide the location of systems, while similarity and allometry reveal their functional mechanism.’Conclusions: The theory of brain dynamics was established in two stages. The first (between 1938 and 1950) had an important clinical foundation, involving the observation of new phenomena and the formulation of new concepts. The second (between 1950 and 1960) included the introduction of more far-reaching concepts, such as the functional cortical gradient, and allometry laws based on a change of scale. Today, various authors believe that the concept of the gradient is crucial for understanding how the brain is organised.(AU)

Influencia de la capacidad manipulativa en la calidad de vida y actividades de la vida diaria en la esclerosis múltiple / Influence of manipulative skills on quality of life and activities of daily living in multiple sclerosis

Introducción: Más de un 50% de los pacientes diagnosticados con esclerosis múltiple (EM) comunican problemas con la función manipulativa e impedimentos en su vida diaria a causa de esta alteración. Por ello, el objetivo del presente estudio es determinar la afectación que la fuerza de pinza, la fuerza de presa y la destreza manipulativa ejercen sobre la calidad de vida y la autonomía personal de las personas diagnosticadas de EM, y estudiar si existe diferencia de estos aspectos entre los distintos tipos de esta enfermedad. Sujetos y métodos: Se contó con una muestra total de 126 participantes, de los cuales 57 fueron controles, y 69, casos. A todos ellos se les evaluó con el Multiple Sclerosis Quality of Life-54, el Nine-Hole Peg Test, la dinamometría de pinza y de presa para la medición de la fuerza, y el índice de Barthel para la evaluación de las actividades básicas de la vida diaria. Resultados: Las personas con EM presentaron peores fuerza de pinza, fuerza de presa, destreza manipulativa, desempeño en actividades básicas de la vida diaria y calidad de vida (p < 0,001). La fuerza de presa es un factor condicionante en el desempeño de actividades básicas y calidad de vida en personas con EM. En cuanto al tipo de EM, el tipo remitente-recurrente presentó mejores valores (p < 0,001).Conclusiones: Los hallazgos de este estudio apuntan a que los pacientes diagnosticados con EM presentan una disminución en la fuerza de pinza, la fuerza de presa, la destreza manipulativa, la calidad de vida y la autonomía en las actividades de la vida diaria en comparación con la población sana.(AU)

Introduction: More than 50% of patients diagnosed with multiple sclerosis report problems with manipulative function and impairments in their daily lives due to this disorder. Therefore, the aim of the present study is to determine how pinch strength, prey strength and manipulative dexterity affect the quality of life and personal autonomy of people diagnosed with multiple sclerosis and to study whether there is a difference in these aspects between different types of multiple sclerosis.Subjects and methods: There was a total sample of 126 participants, of which 57 were controls and 69 cases. All of them were assessed with a Multiple Sclerosis Quality of Life-54 test, Nine-Hole Peg Test and Barthel Index.Results: People with multiple sclerosis have worse pinch strength, prey strenght, manipulative dexterity, performance in basic activities of daily living and quality of life (p < 0.001). Prey strength is a conditioning factor for performance and quality of life in people with multiple sclerosis. As for the type of multiple sclerosis, relapsing-remitting multiple sclerosis presented better values (p < 0.001).Conclusions: The findings of this study point to the fact that patients diagnosed with multiple sclerosis have a decrease in prey strength, pinch strength, manipulative dexterity, quality of life and autonomy in activities of daily living compared to the healthy population.(AU)

Characterizing Vitamin B12 Deficiency in Neurology Outpatients: A Retrospective Observational Study.

OBJECTIVES: Clinical manifestations of vitamin B12 deficiency are varied and may result in missed or delayed diagnosis. This investigation explores the diverse clinical manifestations and demographic characteristics of vitamin B12 deficiency in neurology outpatients, aiming to enhance timely diagnosis and outcomes. METHODS: The severity of vitamin B12 deficiency was classified as absolute (≤150 pg/mL) or borderline deficiency (150-300 pg/mL). We conducted a retrospective analysis of 165 outpatients with vitamin B12 deficiency at the department of neurology between May 2020 and May 2021. RESULT: Absolute vitamin B12 deficiency was found in 23.0% of the patients. The most common age range was 50-60 years, the most common cause was vegetarianism, and the most common symptom was headache. Epileptiform symptoms were more likely to occur in younger patients (<20 years old) with vitamin B12 deficiency, whereas psychiatric symptoms were more likely to occur in older patients (>70 years old). Vegetarians, salivation, and nonmegaloblastic anemia were more obvious in patients with absolute vitamin B12 deficiency, whereas headaches often showed borderline B12 deficiency. CONCLUSIONS: The clinical characteristics of vitamin B12 deficiency are complex and nonspecific. The diagnosis should be based on multiple factors.

François Rabelais and his dystonic giants.

Spasmodic torticollis was an early designation used for cervical dystonia. The origin of this name is attributed to French physician and writer François Rabelais in the mid-sixteenth century. This early description of torticollis in the book Pantagruel was an inspiration for the understanding of cervical dystonia. The art expressed in Rabelais' literature ‒ which was immortalized by the drawings of Gustave Doré ‒ influenced poetry, art, and photography, and led to the adoption of the term torticollis in the neurological sciences.

Uma designação inicial usada para distonia cervical era torcicolo espasmódico. A origem desse termo é atribuída ao médico e escritor francês François Rabelais em meados do século XVI. Essa descrição inicial do torcicolo no livro Pantagruel foi uma inspiração para a compreensão da distonia cervical. A arte exibida na literatura de Rabelais ‒ imortalizada pelos desenhos de Gustave Doré ‒ influenciou a poesia, a arte e a fotografia, e levou à adoção do termo torcicolo nas ciências neurológicas.
