Evaluación de síntomas neuropsiquiátricos para la detección temprana de trastorno neurocognoscitivo / Evaluation of neuropsychiatry symptoms for the early detection of neurocognitive disorder

RESUMEN INTRODUCCIÓN: El diagnóstico oportuno del trastorno neurocognitivo es de los principales retos en la atención de los trastornos neurocognitivos. Por esto, se han generado estrategias para la detección preclínica de la enfermedad, entre ellas las destinadas a evaluar síntomas neuropsiquiátricos (NPS) como la escala Mild Behavior Impairment - Checklist (MBI-C). MÉTODOS: Inicialmente se realizó una búsqueda en BVSalud, Medline y PsycNet, luego se realizó una búsqueda en bola de nieve. Se incluyeron términos referentes a deterioro comportamental leve (abarcando los NPS en etapas tempranas), deterioro cognitivo leve y términos específicos del MBI-C. RESULTADOS: La presencia de NPS se asocia con un aumento en la incidencia anual de demencia. Al evaluarlos con MBI-C, su puntuación se correlaciona con biomarcadores como una mayor atrofia cortical, la presencia de la proteína β-amiloide, así como disminución en funciones ejecutivas como la capacidad de enfocar la atención y la memoria de trabajo. DISCUSIÓN: Los hallazgos en la literatura sugieren la utilidad de MBI-C como marcador de neurodegeneración en estadios previos a la demencia, esto mediante la evaluación de su capacidad predictiva de forma independiente y al compararla con otros biomarcadores. CONCLUSIONES: MBI-C supone ser un instrumento de fácil aplicabilidad e interpretación, sostenible e incluyente. Sin embargo, quedan vacíos sobre la pertinencia de esta escala, por lo que surge la necesidad de investigar este tema.

ABSTRACT INTRODUCTION: Early diagnosis of neurocognitive disorder is the main challenge of dementia health attention. Therefore, strategies for preclinical detection of the disease have been created, like those intended to evaluate neuropsychiatric symptoms (NPS), like the Mild Behavior Impairment - Checklist (MBI-C). METHODS: Research was performed in BVSalud, Medline, and Psynet. Then a snowball sampling was done. The terms included were mild behavioral impairment (included NPS in initial stages), mild cognitive impairment, and specific terms of MBI-C. RESULTS: The presence of NPS increase the incidence of dementia, with an annual conversion rate of 9%. About MBI-C, the score has been related to biomarkers like worse brain atrophy in patients with Parkinson's Disease and a positive relationship with the presence of B-amyloid protein. Also, Creese and cols. show that mild behavioral impairment (measured by MBI-C) is associated with a faster decrease in attention and working memory. DISCUSSION: MBI-C utility as a neurodegenerative marker has been demonstrated to detect cognitive, neuropsychiatry, and functional symptoms that may precede dementia by evaluating its predictive capacity alone and comparing it to other biomarkers. CONCLUSION: MBI-C is easy to apply and interpret, is sustainable and inclusive. However, there are still gaps in the relevance of the scale, so there is the need to continue investigating this topic.

Butler e a psicanálise: do fracasso das normas à estranheza do gozo / Butler and psychoanalysis: from the failure of norms to the uncanniness of jouissance / Butler y el psicoanálisis: del fracaso de las normas a la rareza del goce

O objetivo deste artigo é fazer avançar o debate entre a psicanálise e os estudos queer, em especial a partir da interlocução traçada por Judith Butler com os trabalhos de Freud e Lacan. Retomando o modo como Butler articula Foucault, Derrida e a psicanálise para pensar os problemas de gênero, evidenciamos que a teoria psicanalítica permite à filósofa situar, a partir de sua concepção da melancolia de gênero, os pontos de fracasso da norma em função da vida psíquica do poder. Ainda que a cisheterossexualidade normativa imponha um roteiro de identificações e escolhas de objeto a seus sujeitos, há uma imprevisibilidade na maneira pela qual cada um responderá às injunções normativas da cultura, o que aponta para uma falha das normas em determinar completamente a subjetividade. A melancolia de gênero se torna, assim, uma marca da importância da psicanálise no percurso de Butler. Em seguida, discutimos as interpelações da filósofa ao simbólico lacaniano, bem como as nuances progressivamente introduzidas em sua leitura da diferença sexual. Ao longo do percurso de Butler, a diferença sexual deixa de ser considerada uma teoria da heterossexualidade e passa a ser apresentada como um conceito-borda, uma fronteira vacilante, que tomamos aqui como um convite para produzirmos uma releitura não normativa da diferença sexual na psicanálise a partir da teoria lacaniana da sexuação. Finalmente, localizamos a estranheza do gozo e o caráter irredutível da sexualidade às normas sociais como um importante eixo partilhado entre Butler e a psicanálise.(AU)

The aim of this article is to branch out the debate between psychoanalysis and queer studies, focusing on the interlocution drawn by Judith Butler with the works of Freud and Lacan. Returning to the way Butler articulates Foucault, Derrida and psychoanalysis to think about gender trouble, we show that psychoanalytic theory allows the philosopher to situate, from her conception of gender melancholy, the points of failure of the norm in function of the psychic life of power. After all, even though normative cis-heterosexuality imposes a script of identifications and object-choices on its subjects, there is an unpredictability to the way in which each one will respond to the normative injunctions of culture, so that norms fail to fully determine subjectivity. Gender melancholy thus becomes a mark of the importance of psychoanalysis in Butler's path. Then, we discuss the philosopher's interpellations to the Lacanian symbolic order, as well as the nuances progressively introduced in her reading of sexual difference. Along Butler's path, sexual difference is no longer considered a theory of heterosexuality and is presented as a border-concept, a vacillating frontier, which we take here as an invitation to produce a non-normative rereading of sexual difference in psychoanalysis, resorting to the Lacanian theory of sexuation. Finally, we locate the uncanniness of jouissance and the irreducible character of sexuality to social norms as an important shared axis between Butler and psychoanalysis.(AU)

Volviendo a la forma en que Butler articula a Foucault, Derrida y el psicoanálisis para pensar los problemas de género, mostramos que la teoría psicoanalítica permite a la filósofa ubicar, desde su concepción de la melancolía de género, los puntos de falla de la norma en función de la vida psíquica del poder. Aunque la cis-heterosexualidad normativa imponga identificaciones y elecciones de objeto a sus sujetos, hay una imprevisibilidad en la forma en que cada uno responderá a los mandatos normativos de la cultura, lo que apunta a un fracaso de las normas para determinar completamente la subjetividad. La melancolía de género se convierte, entonces, en una marca de la importancia del psicoanálisis en la trayectoria de Butler. En seguida, discutimos las interpelaciones de la filósofa a lo simbólico lacaniano, así como los matices progresivamente introducidos en su lectura de la diferencia sexual.

Finalmente, ubicamos la rareza del goce y el carácter irreductible de la sexualidad a las normas sociales como un importante eje compartido entre Butler y el psicoanálisis.(AU)

Treatment adherence in patients with diffuse neuropsychiatrie disorders associated with systemic lupus erythematosus / Adherencia al tratamiento en pacientes con trastornos neuropsiquiátricos difusos asociados a lupus eritematoso sistémico

ABSTRACT Introduction: Systemic lupus erythematosus (SLE) is a chronic disease that affects multiple systems and may include neurological and psychiatric events that could compromise treatment adherence and long-term outcomes in SLE. Objective: To evaluate treatment adherence in patients with diffuse neuropsychiatric disorders associated with SLE. Methods: A cross-sectional descriptive study was conducted. Treatment adherence was eval uated with the Morisky Medication Adherence Scale (MMAS-8) in patients with diffuse neuropsychiatric disorders associated with SLE (cognitive impairment, psychosis, mood disorders, and anxiety). Results: A total of 60 patients with neuropsychiatric disorders associated with SLE were included. Thirteen patients (21.6%) had high adherence, 9 (15%) had medium adherence, and 38 patients (63.3%) had low treatment adherence. Conclusion: This study has identified that almost two-thirds of the participants (63.3%) had low treatment adherence.

RESUMEN Introducción: El lupus eritematoso sistémico (LES) es una enfermedad crónica que afecta a múltiples sistemas, entre ellos el sistema nervioso, con eventos neurológicos y psiquiátricos que podrían influir en la adherencia al tratamiento y los resultados a largo plazo de la enfermedad.

Neuropsiquiatría del síndrome de Susac: a propósito de un caso / Neuropsychiatry of Susac Syndrome: a Case Report

RESUMEN El síndrome de Susac es una entidad clínica poco frecuente, posiblemente mediada por un proceso autoinmune; la tríada clásica se compone de retinopatía, disminución en la agudeza auditiva y síntomas neuropsiquiátricos (encefalopatía). Hay pocos casos descritos con sintomatología neuropsiquiátrica como la sintomatología principal. Presentamos un caso de síndrome de Susac, que corresponde a una mujer de 34 arios, con predominio de sintomatologia neuropsiquiátrica, caracterizada por un síndrome de Klüver-Bucy parcial, un síndrome apático, risa y llanto patológico y alteraciones cognitivas de predominio atencional; dichos síntomas mejoraron cualitativamente con el uso de terapia inmunológica. Este caso revela la importancia de las manifestaciones neuropsiquiátricas como presentación clínica en pacientes con entidades neurológicas.

ABSTRACT Susac syndrome is a rare clinical condition, possibly mediated by an autoimmune process; the classic triad is composed of retinopathy, decreased hearing acuity and neuropsychiatric symptoms (encephalopathy). There are few cases reported with neuropsychiatric symptoms as the main manifestation. We present a case of Susac syndrome in a 34-year-old female with a predominance of neuropsychiatric symptoms, characterised by partial Klüver-Bucy syndrome, apathy syndrome, pathological laughter and crying, and cognitive dysfunction predominantly affecting attention, which showed a qualitative improvement with the use of immunological therapy. This case report highlights the importance of neuropsychiatric manifestations as clinical presentation in patients with neurological conditions.

Síndrome de Sjögren neuropsiquiátrico / Neuropsychiatrie Sjögren's Syndrome

RESUMEN El síndrome de Sjögren primario (SSp) es una enfermedad autoinmune que afecta principalmente al tejido glandular. A pesar de ello, puede involucrar otros sistemas, siendo el compromiso neuropsiquiátrico una manifestación extraglandular común. Su presentación clínica varía ampliamente según el dominio que se encuentre afectado, y por tanto puede dividirse en tres grandes categorías: sistema nervioso central, sistema nervioso periférico y psiquiátrico. Algunas de estas complicaciones comparten mecanismos fisiopatológicos comunes, entre los principales la vasculitis/vasculopatía, la infiltración linfocítica y la presencia de anticuerpos antineuronales. La diversidad en la presentación clínica de esta entidad impide hacer una aproximación diagnóstica común, por lo cual la utilización de estudios específicos depende de un adecuado reconocimiento y de la localización por parte del clínico. El tratamiento debe dirigirse al mecanismo fisiopatológico implicado y, de acuerdo con el tipo de manifestación, puede incluso estar limitado al manejo sintomático.

ABSTRACT Primary Sjögren's syndrome is an autoimmune disease that mainly involves glandular tissue. Despite this, it can potentially develop systemic involvement, within which neuropsychiatric manifestations are common. The clinical presentation may vary widely depending on the domain affected, and may thus be classified into three categories: central nervous system, peripheral nervous system, and psychiatric. Some of these complications share a common pathophysiology, amongst which are vasculitis/ vasculopathy, lymphocytic infiltration and positive antineuronal antibodies. The wide clinical presentation makes it difficult to establish a common diagnostic approach, making it essential for the clinician to recognise and localise the type of compromise, so that diagnostic tools can be more advantageously employed. Treatment must be directed towards the underlying pathophysiology, and depending on the type of compromise, it can even be limited solely to the management of symptoms.

Phineas Gage's great legacy / O grande legado de Phineas Gage

ABSTRACT. The case of Phineas Gage is an integral part of medical folklore. His accident still causes astonishment and curiosity and can be considered as the case that most influenced and contributed to the nineteenth century's neuropsychiatric discussion on the mind-brain relationship and brain topography. It was perhaps the first case to suggest the role of brain areas in determining personality and which specific parts of the brain, when affected, can induce specific mental changes. In addition, his case contributed to the emergence of the scientific approaches that would later culminate in psychosurgery. Gage is a fixed element in the studies of neurology, psychology, and neuroscience, having been solidified as one of the greatest medical curiosities of all time, deserving its prominence.

RESUMO. O caso de Phineas Gage é parte integrante do folclore médico. Seu acidente ainda causa espanto e curiosidade, e pode ser considerado como o caso que mais influenciou e contribuiu para a discussão neuropsiquiátrica do século XIX sobre a relação mente-cérebro e topografia cerebral. Foi talvez o primeiro caso a sugerir o papel de áreas cerebrais na determinação da personalidade e que partes específicas do cérebro, quando afetadas, podem induzir mudanças mentais específicas. Além disso, seu caso contribuiu para o surgimento de abordagens cientificas que culminariam posteriormente na psicocirurgia. Gage é um elemento fixo nos estudos de neurologia, psicologia e neurociências, tendo sido solidificado como uma das grandes curiosidades médicas de todos os tempos que merece seu destaque.

Neuropsychiatrie symptoms as the only acute manifestation of a stroke in the left hemisphere. Case report / Alteraciones neuropsiquiátricas como única manifestación de accidente cerebrovascular en hemisferio izquierdo. Reporte de caso

ABSTRACT We report the case of a 60-year-old female patient with a history of hypertension and dyslipidemia, who suddenly presented with a clinical picture of emotional lability, disorientation, complex visual hallucinations and persecutory delusions. There were no associated neurological findings in her initial physical examination. At a local hospital she was initially diagnosed with late-onset bipolar disorder and a manic episode with psychotic features, then referred to the mental health unit, where nuclear magnetic resonance (NMR) imaging of the brain revealed an acute ischemic stroke in the territory of the left posterior cerebral artery (PCA) with haemorrhagic reperfusion to the occipital cortex. Complete and spontaneous resolution of her clinical condition was achieved after approximately 15 days.

RESUMEN Se presenta el reporte de caso de una mujer de 60 anos de edad con antecedente de hipertensión arterial y dislipidemia, quien presenta cuadro clínico de inicio súbito consistente en labilidad emocional, desorientación alopsíquica global, alucinaciones visuales complejas e ideación delirante de tipo persecutorio, sin hallazgos neurológicos asociados en el examen físico inicial. Se enfocó en hospital local como un trastorno bipolar de inicio tardío con episodio actual maníaco con características psicóticas y es remitida a unidad de salud mental. Posteriormente hallazgos de resonancia magnética nuclear (RMN) cerebral revelaron una lesión correspondiente a ataque cerebrovascular (ACV) isquémico agudo en territorio de la arteria cerebral posterior (ACP) izquierda con reperfusión hemorrágica a nivel de corteza occipital. Se alcanzó una resolución espontánea completa de su cuadro clínico en un curso aproximado de 15 días.

Comorbilidad neuropsiquiátrica en pacientes con fibromialgia / Neuropsychiatric comorbidity in patients with fibromyalgia

RESUMEN Introducción: La fibromialgia es una causa común de dolor crónico en el mundo, con una prevalencia en la población general del 0,2% al 6,4%. Estos pacientes tienen una mayor probabilidad de presentar trastornos neuropsiquiátricos. El objetivo fue describir el perfil sociodemográfico y clínico de pacientes con fibromialgia y comorbilidad neuropsiquiátrica. Métodos: Estudio transversal, descriptivo. Se recolectó información de las historias clínicas de pacientes con fibromialgia y comorbilidad neuropsiquiátrica, de una institución especializada en Antioquia, durante los años 2010 al 2016. Se aplicaron herramientas de estadística descriptiva. Resultados: De 1.106 registros médicos con diagnóstico confirmado de fibromialgia, 497 presentaban comorbilidad neuropsiquiátrica. La mediana de edad fue de 54 años (RIC 15), la mayoría eran mujeres, residían en zona urbana y estaban casados o convivían con su pareja. Estatus socioeconómico bajo-medio y nivel educativo básico-medio, fueron los más reportados. Los síntomas más frecuentes fueron alteraciones del sueño (70,6%), mialgias (66,4%) y fatiga crónica (55,9%). Los trastornos neuropsiquiátricos más frecuentes fueron depresión (85,7%), migraña (35%) y ansiedad (14,7%). Los fármacos más utilizados fueron los inhibidores de la recaptación de serotonina y duales, acetaminofén y gabaérgicos. Manejo con terapias complementarias e intervención psicológica se observaron en baja proporción. Conclusiones: La fibromialgia y las enfermedades neuropsiquiátricas son patologías que coexisten con frecuencia; la presentación sociodemográfica y clínica es similar a lo descrito en la literatura, sin embargo, la presencia de depresión en esta población fue mayor. Un enfoque terapéutico transdisciplinario, favorecería la calidad de vida de los pacientes y el curso de la enfermedad.

ABSTRACT Introduction: Fibromyalgia is a common cause of chronic pain in the world, with a prevalence of 0.2% to 6.4% in the general population. These patients are more likely to have neuropsychiatric disorders. The objective of this study was to describe the sociodemographic and clinical profile of patients with fibromyalgia and neuropsychiatric comorbidity. Methods: A cross-sectional, descriptive study was conducted in which Information was collected from the medical records of patients with fibromyalgia and neuropsychiatric comorbidity, from specialist institution in Antioquia, during the years 2010 to 2016. Descriptive statistics tools were applied. Results: Of the 1,106 medical records with a confirmed diagnosis of fibromyalgia, 497 had neuropsychiatric comorbidity. The median age was 54 years (IQR 15), and the majority were women, residing in an urban area, and were married or living with their partner. Low-medium socioeconomic status and basic-medium educational level were the most reported. The most frequent symptoms were sleep disturbances (70.6%), myalgia (66.4%), and chronic fatigue (55.9%). The most frequent neuropsychiatric disorders were depression (85.7%), migraine (35%), and anxiety (14.7%). The most commonly used drugs were serotonin and dual reuptake inhibitors, acetaminophen, and GABAergic drugs. A low percentage was managed with complementary therapies and psychological intervention. Conclusions: Fibromyalgia and neuropsychiatric diseases are diseases that frequently coexist. Although the sociodemographic and clinical presentation is as described in the literature, the presence of depression was greater in this population. A multidisciplinary therapeutic approach would favour the quality of life of the patients and the course of the disease.

The BvFTD is associated with a hypofunction in the areas of the prefrontal cortex, cingulate cortex and others. Apathy and disinhibition are the main symptomatology of study. Conclusions. There is a lack of updated articles that describe neuropsychiatric characteristics along with their imaging description in this population that favors the development of medical and non-medical approaches.

Cognitive impairment in bipolar disorder Neuroprogression or behavioral variant frontotemporal dementia? / Comprometimento cognitivo no transtorno bipolar: neuroprogressão ou variante comportamental da demência frontotemporal?

ABSTRACT Patients with Bipolar Disorder (BD) usually display cognitive deficits with aging. However, the correlation between BD and dementia syndromes is inconclusive, despite the similarity with behavioral variant frontotemporal dementia. We report a 78-year-old female patient who had bipolar type 1 disorder since adolescence. Her symptoms ranged from apathy to psychotic mania. She had had three hospitalizations, and since her last stay 10 years ago, her symptoms had remained stable. However, in the past 2 years, she displayed different symptoms, such as irritability manifested as verbal and physical aggression, cognitive impairment, repetitive pattern of behavior, perambulation, persecutory delusions, disorientation, and hyporexia. Treatment with anticholinesterases or mood stabilizers promoted no improvement. She scored 17/30 points on the Mini-Mental State Examination. Neuropsychological assessment suggested deficits in executive function, attention, and memory. Neuroimaging tests revealed frontotemporal degeneration and hypoperfusion. Diagnostic and therapeutic approaches for this type of patient represent a significant challenge for clinicians.

RESUMO Pacientes com Transtorno Bipolar (TB) costumam apresentardéficits cognitivosao envelhecer. No entanto, a correlação com síndromes demenciais é inconclusiva, apesar da similaridade com a variante comportamental da demência frontotemporal (bvFTD). Nósrelatamos uma paciente de 78 anos de idade com TB tipo 1 desde a adolescência. Seus sintomas variavam de apatia a mania psicótica. A paciente passou por 3 internações, sendo a última há 10 anos, seguida de estabilização clínica. No entanto, nos últimos 2 anos, ela apresentou sintomas diferentes, como irritabilidade expressada por agressões verbal e física, comprometimento cognitivo, padrão repetitivo de comportamento, perambulação, delírios persecutórios, desorientação e hiporexia. O tratamento com anticolinesterásicos ou estabilizadores de humor não revelou melhora. Apresentou 17/30 pontos no miniexame do estado mental, a avaliação neuropsicológica sugeriu déficit de função executiva, atenção e memória. Os exames de neuroimagem demonstraram atrofia e hipoperfusão fronto-temporal. Abordagens diagnósticas e terapêuticas para este tipo de paciente representam um desafio significativo para os clínicos.

Sundown syndrome in patients with Alzheimer's disease dementia / Síndrome do entardecer em pacientes portadores de demência da doença de alzheimer

ABSTRACT The sundown syndrome is a complex neurobehavioral disorder in patients with dementia associated with high financial cost and significant caregiver burden. It is a multifactorial phenomenon with unclear pathophysiology, characterized by the presence of neuropsychiatric symptoms in the evening period. Objective: To analyze the main neuropsychiatric symptoms, their correlation with one another, with comorbidities, and with time of day of greatest symptom intensity in patients with Alzheimer's disease dementia. Methods: This is a cross-sectional, observational and explanatory study in which caregivers/relatives of elderly patients with dementia were interviewed using a structured tool called the Neuropsychiatric Inventory (NPI). Results: The sample studied was composed of 38 patients, 60.5% female and 39.5% male, with mean age of 81±6 (67-94) years. A high frequency of neuropsychiatric symptoms in the evening period was observed, predominantly irritability (55.3%), nocturnal behavior (47.4%), and aggressiveness (42.1%). Only 36.8% of the family caregivers used non-pharmacological strategies. Conclusion: The frequency of neuropsychiatric symptoms was exacerbated in the evening among patients with Alzheimer's disease, especially for those behavioral symptoms that had a positive correlation with one another.

RESUMO A síndrome do entardecer ou "pôr do sol" - "sundown syndrome" - é uma alteração neurocomportamental complexa em pacientes portadores de demência que geram custos financeiros excessivos e desgaste importante a seus cuidadores. Trata-se de um fenômeno multifatorial com fisiopatologia incerta, que caracteriza-se pela presença de sintomas neuropsiquiátricos no período vespertino. Objetivo: Analisar os principais sintomas neuropsiquiátricos, sua correlação entre si, com comorbidades e o horário do dia de maior intensidade destes em pacientes portadores de demência da doença de Alzheimer. Métodos: Trata-se de um estudo analítico transversal, observacional e explanatório no qual foram entrevistados cuidadores/familiares de pacientes idosos portadores de demência utilizando uma ferramenta estruturada denominada Neuropsychiatric Inventory (NPI). Resultados: A amostra estudada foi de 38 pacientes, 60,5% feminino e 39,5% masculino, com 81±6 (67-94) anos de idade. Foi observada uma alta frequência de sintomas neuropsiquiátricos no período vespertino, principalmente irritabilidade (55,3%), comportamento noturno (47,4%), agressividade (42,1%). Apenas 36,8% dos cuidadores familiares empregavam estratégias não farmacológicas. Conclusão: A frequência dos sintomas neuropsiquiátricos são exacerbados ao entardecer em pacientes com doença de Alzheimer; principalmente os sintomas comportamentais com correlação positiva entre si.

Non-invasive brain stimulation therapies / Terapias de neuroestimulação não invasivas

Noninvasive brain stimulation therapies are a promising field for the development of new protocols for the treatment of neuropsychiatric disorders. They are based on the stimulation of neural networks with the intent of modeling their synaptic activity to adequate levels. For this, it is necessary to precisely determine which networks are related to which brain functions, and the normal activation level of each of these networks, so that it is possible to direct the stimulation to the affected networks in order to induce the desired effects. These relationships are under intense investigation by the scientific community, and will contribute to the advancement of treatments by neurostimulation, with the emergence of increasingly accurate and effective protocols for different disorders. Currently, the most used techniques are Transcranial Direct Current Stimulation and Transcranial Magnetic Stimulation, with the most common applications being for treating Major Depressive Disorder. The advancement of research in this field may determine new target networks for stimulation in the treatment of other disorders, extending the application of these techniques and also our knowledge about brain functioning.

As terapias biológicas não invasivas se apresentam como um campo promissor para o desenvolvimento de novos protocolos de tratamento de transtornos neuropsiquiátricos. Elas se baseiam na estimulação de redes neurais com intuito de modular sua atividade sináptica para níveis adequados. Para isso, é necessário a determinação precisa de quais redes estão relacionadas a quais funções cerebrais, e do nível de ativação normal de cada uma dessas redes, para que então seja possível direcionar a estimulação às redes afetadas a fim de induzir os efeitos desejados. Essas relações estão sob intensa investigação pela comunidade científica, e vão contribuir para o avanço dos tratamentos por neuroestimulação, com o surgimento de protocolos cada vez mais precisos e efetivos para diferentes transtornos. Atualmente, as técnicas mais utilizadas são a Estimulação Transcraniana por Corrente Contínua e a Estimulação Magnética Transcraniana, sendo a aplicação mais comum no tratamento do Transtorno Depressivo Maior. O avanço das pesquisas possivelmente determinará novas redes alvo para estimulação no tratamento de outros transtornos, estendendo a aplicação dessas técnicas e também do nosso conhecimento sobre o funcionamento cerebral.

From Charcot's descriptions to the current understanding of neuropsychiatric symptoms in multiple sclerosis / Das descrições de Charcot à compreensão atual dos sintomas neuropsiquiátricos na esclerose múltipla

ABSTRACT Neuropsychiatric disorders in multiple sclerosis have been known since the original clinicopathological description by Charcot in the late nineteenth century. Charcot, in the last decades of his life, became involved in the field of neuropsychiatry. This produced a battle between rival schools in the era that still echoes to this day. Charcot's intuition, including the line of thought of Babinski, one of his most famous disciples, was that there was a connection between mood disorders and many of the diseases of the nervous system. Medicine's concern with establishing a relationship between mood disorders and disease stems from the ancient and middle ages with references found in the Hippocratic doctrine. However, it was only in the second half of the nineteenth and early twentieth century, with Charcot's discoveries, that this discussion was established in a structured way, laying the foundations of neuropsychiatry.

RESUMO Os distúrbios neuropsiquiátricos na esclerose múltipla são conhecidos desde a descrição clínico-patológica original de Charcot no final do século XIX. Charcot nas últimas décadas de sua vida se envolveu no campo da neuropsiquiatria. Isso produziu uma batalha de escolas rivais na época que ainda ecoa até hoje. A intuição de Charcot, incluindo a linha de pensamento de Babinski, um de seus discípulos mais famosos, foi a teoria correta da conexão entre os transtornos do humor e muitas das doenças do sistema nervoso. A preocupação da Medicina em estabelecer uma relação entre transtornos do humor e doenças vem das idades antiga e média, com referências encontradas na doutrina hipocrática. No entanto, foi apenas na segunda metade do século XIX e início do século XX que, com as descobertas de Charcot essa discussão foi realizada de maneira estruturada, estabelecendo os fundamentos da neuropsiquiatria.

Hermann Oppenheim, a pioneer of modern German neurology / Hermann Oppenheim, um pioneiro da moderna neurologia alemã

Hermann Oppenheim (1858-1919) was a leading fgure of the modern German neurology. In spite of the antisemitic ofcial policy, besides his complex personality, he had achieved widespread recognition of his professional qualifcation that attracted neurologists from all around the world to his private clinic. However, he did not held prominent positions at University milieu, in spite of being the main assistant to Karl Westphal (1833­1890) at the Charité-Hospital, in Berlin. Oppenheim was the author of an encyclopedic book of neurology titled "Lehrbuch der Nervenkrankheiten für Ärzte und Studierende" ("Textbook of Nervous Diseases for Doctors and Students"), frst ed., 1894. He also published signifcant works on several disorders, including "traumatic neurosis" (1889) that was criticized by Jean-Martin Charcot (1825­1893), among others. He was clinically responsible for the frst successful removal of brain tumors, including pineal tumor. He coined the term "dystonia musculorum deformans", and he led to several other achievements such as amyotonia congenita ("Oppenheim's disease"), besides Oppenheim's reflex.

Hermann Oppenheim (1858-1919) foi uma fgura importante da moderna neurologia alemã. Apesar da política ofcial anti-semita, além de sua personalidade complexa, ele alcançou amplo reconhecimento de sua qualifcação profssional que atraiu neurologistas de todo o mundo para sua clínica particular. No entanto, ele não ocupou posições de destaque no meio universitário, apesar de ser o principal assistente de Karl Westphal (1833-1890) no Charité-Hospital, em Berlim. Oppenheim foi o autor de um livro enciclopédico de neurologia intitulado "Lehrbuch der Nervenkrankheiten für Ärzte und Studierende" ("Livro Didático de Doenças Nervosas para Médicos e Alunos"), editado em 1894. Ele também publicou trabalhos signifcativos sobre vários distúrbios, incluindo "neurose traumática" ( 1889) que foi criticado por Jean-Martin Charcot (1825­1893), entre outros. Ele foi clinicamente responsável pela primeira remoção bem sucedida de tumores cerebrais, incluindo o tumor pineal. Ele cunhou o termo "distonia musculorumdeformans" e levou a outras várias conquistas como a amiotonia congênita ("doença de Oppenheim"), além do reflexo de Oppenheim.

Neurodiversidad en el siglo XXI, ¿Moda o realidad? / Neurodiversity in the 21st century: fashion or reality?

La neurodiversidad surge desde la comunidad autista, con una propuesta en que la diversidad en las características humanas aparecen como resultado de variaciones normales en el campo neurológico. Metafóricamente existirían personas con "cableados diferenciados" a partir de los cuales se redefinirían las especificidades humanas. Históricamente estas personas han sido tradicionalmente reducidas a condiciones, discapacidades o patologías, es decir, el énfasis de la mirada habría estado puesto en el déficit o carencia. Ejemplos de la neurodiversidad serían la discalculia, dislexia, dispraxia, Síndrome de Tourette, TDAH y en especial las personas portadoras de trastorno espectro autista (TEA). En un momento histórico en que los movimientos sociales promueven cambios en los paradigmas, distintas personas con condiciones neurológicas diversas están trabajando como activistas sociales para generar cambios en la conceptualización de la normalidad y la enfermedad mental. Se pone en jaque así las metodologías de intervención de los sistemas educativos tradicionales y los enfoques clínico en el ámbito de la salud. El presente ensayo busca revisar el estado del arte en la mirada moderna y postmoderna de los conceptos de las patologías neuropsiquiátricas y de la neurodiversidad.

Abstract. Neurodiversity arises from the autistic community, with a proposal in which diversity in human characteristics are a result of normal variations in the neurological field. Metaphorically, there would be people with " differentiated wiring" from which human specificities would be redefined. Historically, these people have been traditionally reduced to pathologies, disabilities, or conditions, i.e., the emphasis of the perspective has been in deficit or lack of something. Examples of neurodiversity would be dyscalculia, dyslexia, dyspraxia, Tourette Syndrome, ADHD, and especially, people living with autism spectrum disorders (ASD). In a historical moment in which social movements promote changes in paradigms, different people with various neurological conditions are working as social activists to generate changes in the conceptualization of normality and mental illness. This questions the intervention methods in traditional educational systems and the clinical approaches in the field of health. This essay seeks to review the state of the art in modern and postmodern concepts of neuropsychiatric diseases and the neurodiversity perspective.

Endoplasmic Reticulum Stress: Implications for Neuropsychiatric Disorders / 전남의대학술지

The Endoplasmic reticulum (ER), an indispensable sub-cellular component of the eukaryotic cell carries out essential functions, is critical to the survival of the organism. The chaperone proteins and the folding enzymes which are multi-domain ER effectors carry out 3-dimensional conformation of nascent polypeptides and check misfolded protein aggregation, easing the exit of functional proteins from the ER. Diverse conditions, for instance redox imbalance, alterations in ionic calcium levels, and inflammatory signaling can perturb the functioning of the ER, leading to a build-up of unfolded or misfolded proteins in the lumen. This results in ER stress, and aiming to reinstate protein homeostasis, a well conserved reaction called the unfolded protein response (UPR) is elicited. Equally, in protracted cellular stress or inadequate compensatory reaction, UPR pathway leads to cell loss. Dysfunctional ER mechanisms are responsible for neuronal degeneration in numerous human diseases, for instance Alzheimer's, Parkinson's and Huntington's diseases. In addition, mounting proof indicates that ER stress is incriminated in psychiatric diseases like major depressive disorder, bipolar disorder, and schizophrenia. Accumulating evidence suggests that pharmacological agents regulating the working of ER may have a role in diminishing advancing neuronal dysfunction in neuropsychiatric disorders. Here, new findings are examined which link the foremost mechanisms connecting ER stress and cell homeostasis. Furthermore, a supposed new pathogenic model of major neuropsychiatry disorders is provided, with ER stress proposed as the pivotal step in disease development.

Similarities of Aspects of Biological Rhythms between Major Depression and Bipolar II Disorder Compared to Bipolar I Disorder: A Finding from the Early-Onset Mood Disorder Cohort

OBJECTIVE: The biological rhythm is closely related to mood symptoms. The purpose of this study was to assess the differences in biological rhythms among subjects with mood disorder [bipolar I disorder (BD I), bipolar II disorder (BD II), major depressive disorder (MDD)] and healthy control subjects.METHODS: A total of 462 early-onset mood disorder subjects were recruited from nine hospitals. The controls subjects were recruited from the general population of South Korea. Subject groups and control subject were evaluated for the Korean language version of Biological Rhythms Interview of Assessment in Neuropsychiatry (K-BRIAN) at the initial evaluation.RESULTS: The mean K-BRIAN scores were 35.59 [standard deviation (SD)=13.37] for BD I, 43.05 (SD=11.85) for BD II, 43.55 (SD=12.22) for MDD, and 29.1 (SD=8.15) for the control group. In the case of mood disorders, biological rhythm disturbances were greater than that in the control group (p<0.05). A significant difference existed between BD I and BD II (BD I <BD II, p<0.001) and between BD I and MDD (BD I<MDD, p< 0.001) but no difference was observed between BD II and MDD.CONCLUSION: BD II and MDD are similar to each other but different from BD I in biological rhythm patterns in early-onset mood disorder cases. Biological rhythm disturbances are similar for early-onset major depression and BD II.
