- Performance of a sample of patients with Mild Cognitive Impairment (MCI), Alzheimer's Disease (AD) and healthy elderly on a lexical decision test (LDT) as a measure of pre-morbid intelligence(2015) SERRAO, Valéria Trunkl; BRUCKI, Sônia Maria Dozzi; CAMPANHOLO, Kenia Repiso; MANSUR, Letícia Lessa; NITRINI, Ricardo; MIOTTO, Eliane CorreaObjective: The objective of this study was to describe the performance of healthy elderly patients with aging-related pathologies (MCI) and patients with AD on a lexical decision test. Methods: The study included 38 healthy elderly subjects, 61 MCI and 26 AD patients from the Neurology Department of the Hospital das Clinicas, Behavioral and Cognitive Neurology Group. The neuropsychological instruments included the episodic memory test (RAVLT), subtests from the WAIS-III (Matrix Reasoning and Vocabulary) to determine estimated IQ, the Boston naming test (BNT) and Lexical Decision Test (LDT).Results:All groups differed on the MMSE, as expected according to their pathologies, memory tests, naming and estimated IQ. For the vocabulary and the LDT - measures of crystalized intelligence no differences were found. Conclusion: The LDT demonstrated that lexical decision can be used as a measure of pre-morbid IQ among the individuals assessed in a Brazilian sample.
- 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.
- Prevalence of cognitive impairment in Brazilian indigenous community from Amazonas(2022) CARVALHO, Anna Paula de; BRUCKI, Sonia Maria Dozzi; NITRINI, Ricardo; BEZERRA, Camila Carlos; SILVA, Fernanda Carini da; SOUZA-TALARICO, Juliana Nery deABSTRACT. Studies on the prevalence of dementia in the indigenous population are still scarce worldwide. In the few available studies, prevalence evidence varies from low to very high, with early onset of the disease and high mortality rate after the initial diagnosis. Still, little is known about the rate of dementia in indigenous populations from low- and middle-income countries, where the dementia prevalence in the general population is estimated to increase significantly in the next decades. Objective: This study aimed to determine the prevalence of cognitive impairment and associated factors in Brazilian indigenous people of the Mura ethnicity in Amazonas, Brazil. Methods: A total of 217 indigenous individuals aged 50 years and older from Amazonas, Brazil, were submitted to cognitive assessment. Attention, memory, verbal fluency, visuospatial performance, and mood state composed the cognitive impairment diagnosis. Results: The prevalence of cognitive impairment was 43.3% (95%CI 36.6-49.7) and varied according to age [OR=1.03 (95%CI 1.00-1.06)], education [OR=0.74 (95%CI 0.62-0.87)], body mass index [OR=0.91 (95%CI 0.83-0.98)], and income [OR=0.52 (95%CI 0.27-0.99)]. Conclusions: Cognitive impairment had an early onset in an indigenous community, and its prevalence was greater in older individuals with low education and low family income. These findings highlight the importance of implementing public indigenous health policies focusing on health professional training for early cognitive impairment detection.
- Reader response: Circulating cortisol and cognitive and structural brain measures: The Framingham Heart Study(2019) BARBOSA, Breno J. A. P.; SOUZA-TALARICO, Juliana N. de; NITRINI, Ricardo; BRUCKI, Sonia M. D.
- Nonpharmacological interventions for cognitive impairments following primary progressive aphasia: A systematic review of the literature(2013) CARTHERY-GOULART, Maria Teresa; SILVEIRA, Amanda da Costa da; MACHADO, Thais Helena; MANSUR, Leticia Lessa; PARENTE, Maria Alice de Mattos Pimenta; SENAHA, Mirna Lie Hosogi; BRUCKI, Sonia Maria Dozzi; NITRINI, RicardoABSTRACT This study provided a systematic review on nonpharmacological interventions applied to patients diagnosed with Primary Progressive Aphasia (PPA) and its variants: Semantic (SPPA), Nonfluent (NFPPA) and Logopenic (LPPA) to establish evidence-based recommendations for the clinical practice of cognitive rehabilitation for these patients. Methods: A PubMed and LILACS literature search with no time restriction was conducted with the keywords PPA (and its variants) AND rehabilitation OR training OR intervention OR therapy OR treatment OR effectiveness. To develop its evidence-based recommendations, a research committee identified questions to be addressed and determined the level of evidence for each study according to published criteria (Cicerone et al., 2000). Overall evidence for treatments was summarized and recommendations were derived. Results: Our search retrieved articles published from 1995 to 2013: 21 for SPPA, 8 for NFPPA, 3 for LPPA and 8 for PPA with no specification. Thirty-five studies were rated as Class III, consisting of studies with results obtained from one or more single-cases and that used appropriate single-subject methods with adequate quantification and analysis of results. The level of evidence of three functional interventions could not be established. One study was rated as Class II and consisted of a nonrandomized case-control investigation. Conclusion: Positive results were reported in all reviewed studies. However, in order to be recommended, some investigation regarding the intervention efficacy was required. Results of the present review allows for recommendation of some nonpharmacological interventions for cognitive deficits following PPA as Practice Options. Suggestions for further studies on PPA interventions and future research are discussed.
- Effects of working memory training on cognition in healthy older adults: A systematic review(2022) LIMA-SILVA, Thais Bento; ORDONEZ, Tiago Nascimento; SANTOS, Gabriela dos; MOREIRA, Ana Paula Bagli; VERGA, Cássia Elisa Rosseto; ISHIBASHI, Graciela Akina; SILVA, Guilherme Alves da; PRATA, Patrícia Lessa; MORAES, Luiz Carlos de; BRUCKI, Sonia Maria DozziABSTRACT. The working memory (WM) training in older adults can benefit their cognition. However, there is a dearth of literature reviews on the subject. Objective: This study aimed to investigate and evaluate the effects of WM training on the cognition of healthy older adults, in individual and group interventions reported in the literature. Methods: This is a systematic review involving a qualitative analysis of publications on the SciELO, LILACS, and MEDLINE databases carried out between March and June 2021. Results: A total of 47 studies were identified and analyzed, comprising 40 in older adults only and 7 comparing older and younger adults, investigating individual or group WM training or other types of intervention focused on WM effects. Conclusions: Both individual and group intervention contributed to the maintenance and/or improvement of cognition in older adults exploiting brain plasticity to promote mental health and prevent cognitive problems that can negatively impact quality of life of this group.
- Recalling feature bindings differentiates Alzheimer's disease from frontotemporal dementia(2017) CECCHINI, Mario Amore; YASSUDA, Monica Sanches; BAHIA, Valeria Santoro; SOUZA, Leonardo Cruz de; GUIMARAES, Henrique Cerqueira; CARAMELLI, Paulo; CARTHERY-GOULART, Maria Teresa; PATROCINIO, Flavia; FOSS, Maria Paula; TUMAS, Vitor; LIMA-SILVA, Thais Bento; BRUCKI, Sonia Maria Dozzi; NITRINI, Ricardo; SALA, Sergio Della; PARRA, Mario A.It has been challenging to identify clinical cognitive markers that can differentiate patients with Alzheimer's disease (AD) from those with behavioral variant frontotemporal dementia (bvFTD). The short-term memory binding (STMB) test assesses the ability to integrate colors and shapes into unified representations and to hold them temporarily during online performance. The objective of this study is to investigate whether free recall deficits during short-term memory binding (STMB) test can differentiate patients with AD from those with bvFTD and controls. Participants were 32 cognitively intact adults, 35 individuals with AD and 18 with bvFTD. All patients were in the mild dementia stage. Receiver-operating characteristic (ROC) analyses were used to examine the diagnostic accuracy of the STMB. The results showed that AD patients performed significantly worse than controls and bvFTD patients in the STMB test, while the latter groups showed equivalent performance. The bound condition of the STMB test showed an AUC of 0.853, with 84.4% of sensitivity and 80% of specificity to discriminate AD from controls and an AUC of 0.794, with 72.2% of sensitivity and 80% of specificity to differentiate AD from bvFTD. Binding deficits seem specific to AD. The free recall version of the STMB test can be used for clinical purposes and may aid in the differential diagnosis of AD. Findings support the view that the STMB may be a suitable cognitive marker for AD.
- Unusual Presentation in Infratentorial Superficial Siderosis: Acute Intracranial Hypertension(2021) ROCHA, Maria Sheila Guimaraes; MIRO, Hugo Salomao Grangeiro; MANFROI, Gregori; DIAS, Arthur De Medeiros; CARDOSO, Raphaella; BRUCKI, Sonia Maria DozziSuperficial siderosis (SS) of the nervous system is a rare acquired condition related to hemosiderin deposits in subpial layers of the brain, brainstem, cerebellum, cranial nerves, and spinal cord, leading to brain iron-mediated neurodegeneration. The cardinal neurological features are slowly progressive hearing loss, ataxia, and pyramidal signs. Here we describe an atypical case of infratentorial SS evolving with acute intracranial hypertension in the absence of typical chronic signs.
- Effects of a Non-focal Plasticity Protocol on Apathy in Moderate Alzheimer's Disease: A Randomized, Double-blind, Sham-controlled Trial(2014) SUEMOTO, Claudia Kimie; APOLINARIO, Daniel; NAKAMURA-PALACIOS, Ester Miyuki; LOPES, Leonardo; LEITE, Renata Elaine Paraizo; SALES, Manuela Castro; NITRINI, Ricardo; BRUCKI, Sonia Maria; MORILLO, Lilian Shafirovitz; MAGALDI, Regina Miksian; FREGNI, FelipeBackground: Apathy is the most common neuropsychiatric symptom in Alzheimer's disease (AD) and it is associated with changes in prefrontal neural circuits involved with generation of voluntary actions. To date no effective treatment for apathy has been demonstrated. Objective: We aimed to investigate the effects and safety of repetitive transcranial direct current stimulation (tDCS) on apathy in moderate AD patients. Methods: Forty patients were randomized to receive either active or sham-tDCS over the left dorsolateral prefrontal cortex (DLPFC). Patients received six sessions of intervention during 2 weeks and were evaluated at baseline, at week 1 and 2, and after 1 week without intervention. Clinical raters, patients, and caregivers were blinded. The primary outcome was apathy. Global cognition and neuropsychiatric symptoms were examined as secondary outcomes. Results: The mean MMSE score at baseline was 15.2 +/- 2.9 and the mean Apathy Scale score was 27.7 +/- 6.7. Changes on apathy scores over time were not different between active and sham tDCS (P = 0.552 for repeated measures). Further analyses confirm that changes from baseline did not differ between groups after the sixth session (active tDCS -1.95 (95%CI -3.49, -0.41); sham-tDCS -2.05 (95% Cl -3.68, 0.42); P = 0.9891. Similarly, tDCS had no effect on secondary outcomes (P > 0.40). tDCS was well tolerated and not associated with significant adverse effects. Conclusion: In this adequately powered study for minimal clinically significant difference, our findings show that using the parameters we chose for this study, repeated anodal tDCS over the left DLPFC had no effect on apathy in elderly patients with moderate AD.
- Visuospatial processing: A review from basic to current concepts(2014) TRÉS, Eduardo Sturzeneker; BRUCKI, Sonia Maria DozziABSTRACT Introduction: Visuospatial processing is a fundamental aspect in human cognition, belonging to a complex and intricate network. It is, in other words, one of the building blocks of an individual's identity and behavior. Objective: To allow an overall and updated review of visuospatial processing and its related events, in light of new techniques and evidence, focusing on basic concepts of higher cortical functions, its pathways and associated systems. Methods: The study was conducted based on the national and international databases LILACS, MEDLINE, ScieLo and Pubmed; using the search word "visuospatial" in combination with "pathway", "processing", "function", "fMRI" and "attention". Results: A total of 77 references deemed relevant for its historical, conceptual or updated relevance were selected out of 1222 retrieved; including English, Spanish and Portuguese languages. A critical review was carried out and many new aspects discussed. Conclusion: A new functioning and construction of sight processing is being shaped, culminating now in a model based on dynamic and integrated interactions between pathways and systems
