    The importance of recognizing faciobrachial dystonic seizures in rapidly progressive dementias
    (2016) SIMABUKURO, Mateus Mistieri; NÓBREGA, Paulo Ribeiro; PITOMBEIRA, Milena; CAVALCANTE, Wagner Cid Palmeira; GRATIVVOL, Ronnyson Susano; PINTO, Lécio Figueira; CASTRO, Luiz Henrique Martins; NITRINI, Ricardo
    ABSTRACT Background: Creutzfeldt-Jakob Disease (CJD) is the prototypical cause of rapidly progressive dementia (RPD). Nonetheless, efforts to exclude reversible causes of RPD that mimic prion disease are imperative. The recent expanding characterization of neurological syndromes associated with antibodies directed against neuronal cell surface or sympathic antigens, namely autoimmune encephalitis is shifting paradigms in neurology. Such antigens are well known proteins and receptors involved in synaptic transmission. Their dysfunction results in neuropsychiatric symptoms, psychosis, seizures, movement disorders and RPD. Faciobrachial dystonic seizure (FBDS) is a novel characterized type of seizure, specific for anti-LGI1 encephalitis. Objective: In order to improve clinical recognition we report the cases of two Brazilian patients who presented with characteristic FDBS (illustrated by videos) and anti-LGI1 encephalitis. Methods: We have included all patients with FBDS and confirmed anti-LGI1 encephalitis and video records of FDBS in two tertiary Brazilian centers: Department of Neurology of Hospital das Clínicas, Sao Paulo University, Sao Paulo, Brazil and Hospital Geral de Fortaleza, Fortaleza, Brazil between January 1, 2011 and December 31, 2015. Results: Both patients presented with clinical features of limbic encephalitis associated with FBDS, hyponatremia and normal CSF. None of them presented with tumor and both showed a good response after immunotherapy. Conclusion: FBDSs may be confounded with myoclonus and occurs simultaneously with rapid cognitive decline. Unawareness of FDBS may induce to misdiagnosing a treatable cause of RPD as CJD.

    Leukoencephalopathy resolution after atypical mycobacterial treatment: a case report
    (2015) OLIVEIRA, Marcos C. B.; SATO, Douglas Kazutoshi; SOARES-NETO, Herval R.; LUCATO, Leandro T.; CALLEGARO, Dagoberto; NITRINI, Ricardo; MEDEIROS, Raphael S. S.; MISU, Tatsuro; FUJIHARA, Kazuo; CASTRO, Luiz H.
    Background: Association of leukoencephalopathy and atypical mycobacteriosis has been rarely reported. We present a case that is relevant for its unusual presentation and because it may shed further light on the pathogenic mechanisms underlying reversible encephalopathies. Case report: We report the case of a Hispanic 64-year-old woman with cognitive decline and extensive leukoencephalopathy. Magnetic resonance imaging revealed white-matter lesions with increased water diffusivity, without blood-brain-barrier disruption. Brain biopsy showed tissue rarefaction with vacuolation, mild inflammation, few reactive astrocytes and decreased aquaporin water-channel expression in the lesions. Six months later, she was diagnosed with atypical mycobacterial pulmonary infection. Brain lesions resolved after antimycobacterial treatment. Conclusion: We hypothesize leukoencephalopathic changes and vasogenic edema were associated with decreased aquaporin expression. Further studies should clarify if reversible leukoencephalopathy has a causal relationship with decreased aquaporin expression and atypical mycobacterial infection, and mechanisms underlying leukoencephalopathy resolution after antimycobacterial treatment. This article may contribute to the understanding of pathogenic mechanisms underlying magnetic resonance imaging subcortical lesions and edema, which remain incompletely understood.

    Acute Disseminated Encephalomyelitis in COVID-19: presentation of two cases and review of the literature
    (2020) LOPES, Cesar Castello Branco; BRUCKI, Sonia Maria Dozzi; PASSOS NETO, Carlos Eduardo Borges; CORAZZA, Luiza Alves; BAIMA, Jose Pedro Soares; FIORENTINO, Matheus Dalben; TATSCH, Joao Fellipe Santos; MARTIN, Maria da Graca Morais; LUCATO, Leandro Tavares; GOMES, Helio Rodrigues; ROCHA, Maria Sheila Guimaraes; FORTINI, Ida; NITRINI, Ricardo; CASTRO, Luiz H.
    Background: Neurological manifestations of COVID-19 are still incompletely understood. Neurological manifestations may be due to direct viral effect on neurons and glial cells, to an immune-mediated response to the virus, or to a hypercoagulable state and associated endothelial damage, as well as to severe systemic disease with prolonged intensive care unit stay. Objective: To describe two patients with severe SARS-CoV-2 infection and delayed recovery of consciousness after sedation withdrawal, in whom MRI disclosed multifocal white matter brain lesions, compatible with the diagnosis of acute disseminated encephalomyelitis. Methods: Observational report of two cases of severe COVID-19 infection in patients from two tertiary hospitals in Sao Paulo, Brazil. Results: These patients underwent neurologic and systemic evaluation for delayed awakening after sedation withdrawal. MRI displayed multifocal centrum semiovale lesions, suggestive of demyelinating inflammation. Cerebrospinal fluid (CSF) polymerase chain reaction (PCR) for SARS-CoV-2 was negative in both cases. Conclusion: A recurrent pattern of multifocal white matter lesions can occur in COVID-19 patients, possibly associated with delayed awakening. Additional studies are necessary to elucidate the role of the viral infection and of inflammatory and immune-mediated associated changes in neurological manifestations of COVID-19.

    Rapidly progressive dementia due to neurosarcoidosis
    (2013) FORTES, Gabriela Carneiro C.; OLIVEIRA, Marcos Castello B.; LOPES, Laura Cardia G.; TOMIKAWA, Camila S.; LUCATO, Leandro T.; CASTRO, Luiz Henrique M.; NITRINI, Ricardo
    ABSTRACT Rapidly progressive dementia (RPD) is typically defined as a cognitive decline progressing to severe impairment in less than 1-2 years, typically within weeks or months. Accurate and prompt diagnosis is important because many conditions causing RPD are treatable. Neurosarcoidosis is often cited as an unusual reversible cause of RPD. Methods: We report two cases of neurosarcoidosis presenting as RPD. Results: Case 1: A 61-year-old woman developed a RPD associated with visual loss. In seven months she was dependent for self-care. Magnetic resonance imaging (MRI) revealed temporal and suprasellar brain lesions. Treatment with high-dose intravenous prednisolone was associated with partial improvement. Case 2: A 43-year-old woman who was being treated for diabetes insipidus developed a severe episodic amnesia one year after onset of cognitive symptoms. Previous MRI had shown a hypothalamic lesion and she had been treated with oral prednisone and cyclophosphamide. There was reduction of the MRI findings but no improvement in the cognitive deficits. Brain biopsy disclosed noncaseous granulomas and granulomatous angiitis; treatment was changed to high-dose intravenous methylprednisolone, with poor symptomatic response. Conclusion: The diagnosis of RPD due to neurosarcoidosis can be challenging when the disease is restricted to the nervous system. In these cases, clinical presentation of RPD associated with neuroendocrine and visual dysfunction, imaging findings showing hypothalamic lesions and, in some cases, brain biopsy, are the key to a correct diagnosis. It is possible that earlier diagnoses and treatment could have led to a better outcome in these patients.

    Background: More than one-third of COVID-19 patients present neurological symptoms ranging from anosmia to stroke and encephalopathy. Furthermore, pre-existing neurological conditions may require special treatment and may be associated with worse outcomes. Notwithstanding, the role of neurologists in COVID-19 is probably underrecognized. Objective: The aim of this study was to report the reasons for requesting neurological consultations by internists and intensivists in a COVID-19-dedicated hospital. Methods: This retrospective study was carried out at Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo, Brazil, a 900-bed COVID-19 dedicated center (including 300 intensive care unit beds). COVID-19 diagnosis was confirmed by SARS-CoV-2-RT-PCR in nasal swabs. All inpatient neurology consultations between March 23rd and May 23rd, 2020 were analyzed. Neurologists performed the neurological exam, assessed all available data to diagnose the neurological condition, and requested additional tests deemed necessary. Difficult diagnoses were established in consensus meetings. After diagnosis, neurologists were involved in the treatment. Results: Neurological consultations were requested for 89 out of 1,208 (7.4%) inpatient COVID admissions during that period. Main neurological diagnoses included: encephalopathy (44.4%), stroke (16.7%), previous neurological diseases (9.0%), seizures (9.0%), neuromuscular disorders (5.6%), other acute brain lesions (3.4%), and other mild nonspecific symptoms (11.2%). Conclusions: Most neurological consultations in a COVID-19-dedicated hospital were requested for severe conditions that could have an impact on the outcome. First-line doctors should be able to recognize neurological symptoms; neurologists are important members of the medical team in COVID-19 hospital care.
