- Diagnóstico e manejo da demência da doença de Parkinson e demência com corpos de Lewy: recomendações do Departamento Científico de Neurologia Cognitiva e do Envelhecimento da Academia Brasileira de Neurologia(2022) PARMERA, Jacy Bezerra; TUMAS, Vitor; FERRAZ, Henrique Ballalai; SPITZ, Mariana; BARBOSA, Maira Tonidandel; SMID, Jerusa; BARBOSA, Breno José Alencar Pires; SCHILLING, Lucas Porcello; BALTHAZAR, Márcio Luiz Figueiredo; SOUZA, Leonardo Cruz de; VALE, Francisco Assis Carvalho; CARAMELLI, Paulo; BERTOLUCCI, Paulo Henrique Ferreira; CHAVES, Márcia Lorena Fagundes; BRUCKI, Sonia Maria Dozzi; NITRINI, Ricardo; CASTILHOS, Raphael Machado; FROTA, Norberto Anízio FerreiraABSTRACT Parkinson’s disease dementia (PDD) and dementia with Lewy bodies (DLB) represent the second most common type of degenerative dementia in patients aged 65 years and older, leading to progressive cognitive dysfunction and impaired quality of life. This study aims to provide a consensus based on a systematic Brazilian literature review and a comprehensive international review concerning PDD and DLB. Moreover, we sought to report on and give recommendations about the best diagnostic approaches focusing on primary and secondary care. Based on the available data, we recommend clinicians to apply at least one brief global cognitive instrument to assess PDD, such as the Mini-Mental State Examination and preferably the Montreal Cognitive Assessment and the Addenbrooke’s Cognitive Examination-Revised. Validated instruments to accurately assess functional abilities in Brazilian PD patients are still incipient. Further studies should focus on biomarkers with Brazilian cohorts.
conferenceObject IMPACT OF COVID-19 PANDEMIC ON MENTAL HEALTH, SOCIAL CONNECTEDNESS AND COGNITIVE PERFORMANCE OF OLDER ADULTS(2021) SOUZA-TALARICO, Juliana; SILVA, Fernanda; JESUS, Maria Clara; BARBOSA, Breno J. A. P.; NITRINI, Ricardo; BRUCKI, Sonia M. D.- Manejo das demências em fase avançada: recomendações do Departamento Científico de Neurologia Cognitiva e do Envelhecimento da Academia Brasileira de Neurologia(2022) BRUCKI, Sonia Maria Dozzi; APRAHAMIAN, Ivan; BORELLI, Wyllians Vendramini; SILVEIRA, Victor Calil da; FERRETTI, Ceres Eloah de Lucena; SMID, Jerusa; BARBOSA, Breno José Alencar Pires; SCHILLING, Lucas Porcello; BALTHAZAR, Márcio Luiz Figueiredo; FROTA, Norberto Anízio Ferreira; SOUZA, Leonardo Cruz de; VALE, Francisco Assis Carvalho; CARAMELLI, Paulo; BERTOLUCCI, Paulo Henrique Ferreira; CHAVES, Márcia Lorena Fagundes; NITRINI, Ricardo; SCHULTZ, Rodrigo Rizek; MORILLO, Lilian SchafirovitsABSTRACT Alzheimer’s disease (AD) and other neurodegenerative dementias have a progressive course, impairing cognition, functional capacity, and behavior. Most studies have focused on AD. Severe dementia is associated with increased age, higher morbidity-mortality, and rising costs of care. It is fundamental to recognize that severe dementia is the longest period of progression, with patients living for many years in this stage. It is the most heterogeneous phase in the process, with different abilities and life expectancies. This practice guideline focuses on severe dementia to improve management and care in this stage of dementia. As it is a long period in the continuum of dementia, clinical practice should consider non-pharmacological and pharmacological approaches. Multidisciplinary interventions (physical therapy, speech therapy, nutrition, nursing, and others) are essential, besides educational and support to caregivers.
- Current clinical and research practices on frontotemporal dementia in Brazil: a national survey(2023) SOUZA, Leonardo Cruz de; BRUCKI, Sonia Maria Dozzi; SCHILLING, Lucas Porcello; SILVA, Leticia Costa da; TAKADA, Leonel Tadao; BAHIA, Valeria Santoro; BARBOSA, Breno Jose Alencar Pires; BALTHAZAR, Marcio Luiz Figueredo; FROTA, Norberto Anizio Ferreira; NITRINI, Ricardo; CARAMELLI, Paulo; SMID, JerusaBackground Frontotemporal dementia (FTD) is a frequent cause of young-onset dementia and represents a major challenge for the diagnosis and clinical management. It is essential to evaluate the difficulties faced by physicians on the diagnostic workup and on patient care.Objective The aim of this study was to investigate the current practices and the local limits on the diagnosis and management of FTD in Brazil.Methods We elaborated an online survey, composed of 29 questions and divided in four parts, comprising questions about existing health facilities, clinical practices related to FTD, and suggestions to increment the national research on FTD. The invitation to participate was sent by email to all neurologists affiliated to the Brazilian Academy of Neurology ( n = 3658), and to all physicians who attended the XII Meeting of Researchers on Alzheimer's disease, in 2019 ( n = 187). The invitation was also diffused through social media.Results 256 Brazilian physicians answered the questionnaire. The three most relevant disorders for the differential diagnosis of FTD were Alzheimer's disease (AD) ( n = 211), bipolar disorder ( n = 117) and dementia with Lewy bodies ( n = 92). Most respondents (125/256) reported the difficulty in performing genetic testing as the main limit in the diagnostic of FTD. 93% and 63% of participants considered that the assessment of social cognition and AD CSF biomarkers are useful for the diagnosis of FTD, respectively.Conclusions The present study may provide valuable insights for the medical education and clinical training of physicians, and to foster future research on FTD in Brazil.

- Gerstmann's syndrome and unilateral optic ataxia in the emergency department(2017) BARBOSA, Breno José Alencar Pires; BRITO, Marcelo Houat de; RODRIGUES, Júlia Chartouni; KUBOTA, Gabriel Taricani; PARMERA, Jacy BezerraABSTRACT. A 75-year-old right-handed woman presented to the emergency department with simultanagnosia and right unilateral optic ataxia. Moreover, the patient had agraphia, acalculia, digital agnosia and right-left disorientation, consistent with complete Gerstmann's syndrome. This case highlights the concurrence of Gerstmann's syndrome and unilateral optic ataxia in the acute phase of a left middle cerebral artery stroke.
- Diagnóstico da doença de Alzheimer: recomendações do Departamento Científico de Neurologia Cognitiva e do Envelhecimento da Academia Brasileira de Neurologia(2022) SCHILLING, Lucas Porcello; BALTHAZAR, Marcio Luiz Figueredo; RADANOVIC, Márcia; FORLENZA, Orestes Vicente; SILAGI, Marcela Lima; SMID, Jerusa; BARBOSA, Breno José Alencar Pires; FROTA, Norberto Anízio Ferreira; SOUZA, Leonardo Cruz de; VALE, Francisco Assis Carvalho; CARAMELLI, Paulo; BERTOLUCCI, Paulo Henrique Ferreira; CHAVES, Márcia Lorena Fagundes; BRUCKI, Sonia Maria Dozzi; DAMASCENO, Benito Pereira; NITRINI, RicardoABSTRACT This paper presents the consensus of the Scientific Department of Cognitive Neurology and Aging from the Brazilian Academy of Neurology on the diagnostic criteria for Alzheimer’s disease (AD) in Brazil. The authors conducted a literature review regarding clinical and research criteria for AD diagnosis and proposed protocols for use at primary, secondary, and tertiary care levels. Within this clinical scenario, the diagnostic criteria for typical and atypical AD are presented as well as clinical, cognitive, and functional assessment tools and complementary propaedeutics with laboratory and neuroimaging tests. The use of biomarkers is also discussed for both clinical diagnosis (in specific conditions) and research.
- Second-Generation RT-QuIC Assay for the Diagnosis of Creutzfeldt-Jakob Disease Patients in Brazil(2020) BARBOSA, Breno Jose Alencar Pires; CASTRILLO, Bruno Batitucci; ALVIM, Ricardo Pires; BRITO, Marcelo Houat de; GOMES, Helio R.; BRUCKI, Sonia M. D.; SMID, Jerusa; NITRINI, Ricardo; LANDEMBERGER, Michele C.; MARTINS, Vilma R.; SILVA, Jerson L.; VIEIRA, Tuane C. R. G.The recent development of IQ-CSF, the second generation of real-time quaking-induced conversion (RT-QuIC) using cerebrospinal fluid (CSF), for the diagnosis of Creutzfeldt-Jakob Disease (CJD) represents a major diagnostic advance in the field. Highly accurate results have been reported with encouraging reproducibility among different centers. However, availability is still insufficient, and only a few research centers have access to the method in developing countries. In Brazil, we have had 603 suspected cases of CJD since 2005, when surveillance started. Of these, 404 were undiagnosed. This lack of diagnosis is due, among other factors, to the lack of a reference center for the diagnosis of these diseases in Brazil, resulting in some of these samples being sent abroad for analysis. The aim of this research study is to report the pilot use of IQ-CSF in a small cohort of Brazilian patients with possible or probable CJD, implementing a reference center in the country. We stored CSF samples from patients with possible, probable or genetic CJD (one case) during the time frame of December 2016 through June 2018. All CSF samples were processed according to standardized protocols without access to the clinical data. Eight patients presented to our team with rapidly progressive dementia and typical neurological signs of CJD. We used CSF samples from seven patients with other neurological conditions as negative controls. Five out of seven suspected cases had positive tests; two cases showed inconclusive results. Among controls, there was one false-positive (a CSF sample from a 5-year-old child with leukemia under treatment). The occurrence of a false positive in one of the negative control samples raises the possibility of the presence of interfering components in the CSF sample from patients with non-neurodegenerative pathologies. Our pilot results illustrate the feasibility of having CJD CSF samples tested in Brazilian centers and highlight the importance of interinstitutional collaboration to pursue a higher diagnostic accuracy in CJD in Brazil and Latin America.
- Diagnóstico da demência frontotemporal: recomendações do Departamento Científico de Neurologia Cognitiva e do Envelhecimento da Academia Brasileira de Neurologia(2022) SOUZA, Leonardo Cruz de; HOSOGI, Mirna Lie; MACHADO, Thais Helena; CARTHERY-GOULART, Maria Teresa; YASSUDA, Mônica Sanches; SMID, Jerusa; BARBOSA, Breno José Alencar Pires; SCHILLING, Lucas Porcello; BALTHAZAR, Marcio Luiz Figueredo; FROTA, Norberto Anízio Ferreira; VALE, Francisco Assis Carvalho; CARAMELLI, Paulo; BERTOLUCCI, Paulo Henrique Ferreira; CHAVES, Márcia Lorena Fagundes; BRUCKI, Sonia Maria Dozzi; NITRINI, Ricardo; BAHIA, Valéria Santoro; TAKADA, Leonel TadaoABSTRACT “Frontotemporal dementia” (FTD) is a clinical syndrome characterized by the focal involvement of the frontal and/or temporal lobes. FTD has three clinical phenotypes: the behavioral variant and two linguistic subtypes, namely, non-fluent/agrammatic primary progressive aphasia (PPA-NF/A) and semantic PPA (PPA-S). FTD is the second most common cause of dementia in individuals under the age of 65 years. This article presents recommendations for the diagnosis of FTD in the Brazilian scenario, considering the three levels of complexity of the health system: primary health care, secondary and tertiary levels. Diagnostic guidelines are proposed, including cognitive testing, behavioral and language assessments, laboratory tests, and neuroimaging.
- Declínio cognitivo subjetivo, comprometimento cognitivo leve e demência - diagnóstico sindrômico: recomendações do Departamento Científico de Neurologia Cognitiva e do Envelhecimento da Academia Brasileira de Neurologia(2022) SMID, Jerusa; STUDART-NETO, Adalberto; CÉSAR-FREITAS, Karolina Gouveia; DOURADO, Marcia Cristina Nascimento; KOCHHANN, Renata; BARBOSA, Breno José Alencar Pires; SCHILLING, Lucas Porcello; BALTHAZAR, Márcio Luiz Figueiredo; FROTA, Norberto Anízio Ferreira; SOUZA, Leonardo Cruz de; CARAMELLI, Paulo; BERTOLUCCI, Paulo Henrique Ferreira; CHAVES, Márcia Lorena Fagundes; BRUCKI, Sonia Maria Dozzi; NITRINI, Ricardo; RESENDE, Elisa de Paula França; VALE, Francisco Assis CarvalhoABSTRACT This consensus, performed by the Brazilian Academy of Neurology (BAN) will approach practically how to evaluate patients with cognitive complaints and how to clinically and etiologically diagnose the three clinical syndromes associated with the different stages of cognitive decline: subjective cognitive decline (SCD), mild cognitive impairment (MCI), and dementia. This BAN consensus discusses SCD diagnosis for the first time, updates MCI and dementia diagnoses, recommends the adequate cognitive tests and the relevant etiological work-up and care of patients with cognitive decline at different levels of care within the Brazilian Unified Health System. We also review the main assessment instruments used in Brazil and Latin America.
