[pt] Esse trabalho se voltou para o desenvolvimento de um teste de avaliação do processamento sintático na compreensão da linguagem no envelhecimento. Esse teste tem como objetivo oferecer um auxílio no diagnóstico de Comprometimento Cognitivo Leve (CCL). Este é um quadro que pode evoluir para a Doença de Alzheimer (DA). Por isso, o diagnóstico o mais cedo possível de um comprometimento cognitivo no envelhecimento pode oferecer um melhor prognóstico para o paciente, a partir de acompanhamento médico e reabilitação neuropsicológica. Sabe-se que a idade avançada é um dos principais fatores de risco para o desenvolvimento da DA. Esta pesquisa se justifica na medida em que a população mundial vem envelhecendo em ritmo acelerado e também pela enorme carência de um instrumento de avaliação voltado para o processamento sintático no envelhecimento e, principalmente, pela carência de um instrumento em português brasileiro. Uma revisão sistemática feita nas plataformas PubMed, LILACS e SciELO revelou que por volta dos últimos 5 anos pouquíssimos estudos avaliaram o processamento sintático de pacientes com CCL. E o número de estudos que consideraram o processamento sintático de sentenças com estrutura mais complexa é mais reduzido ainda. Apresentamos, portanto, neste trabalho, um protótipo de um teste de compreensão de sentenças que variam em nível de complexidade sintática, construído com base em pesquisas na área de Psicolinguística e de Neuropsicologia Clínica. Trata-se de um teste de identificação de figura a partir de uma tarefa de verificação de correspondência entre sentença e imagem. Esse teste explora a compreensão de sentenças com oração relativa de sujeito e de objeto; interrogativas de sujeito e de objeto; clivadas de sujeito e de objeto; passivas reversíveis (implausíveis e neutras) e irreversíveis; estruturas com verbo de perspectiva; e ativas simples reversíveis e irreversíveis. Como a literatura reporta, até mesmo no envelhecimento saudável, espera-se um declínio no processamento dessas estruturas sintáticas mais complexas, que acarretam maior demanda cognitiva. Em um quadro de envelhecimento não saudável, esse declínio estaria mais acentuado e evidente. Por isso, esse teste pode ser uma medida promissora na detecção de um CCL que afete o domínio da linguagem. Foi realizado um estudo piloto com um grupo de 43 adultos mais jovens e um grupo de 10 idosos sem comprometimento cognitivo, para avaliar a funcionalidade do teste desenvolvido. Os dois grupos realizaram a tarefa de identificação de imagens sem dificuldades, com média de tempo similar e baixo percentual de erros, tendo estes ocorrido com as estruturas mais complexas do conjunto de sentenças examinadas. Os resultados do piloto sugerem, portanto, que o teste pode ser um instrumento sensível na avaliação do processamento sintático na compreensão de sentenças por parte de adultos e idosos. / [en] This work focused on the development of a test to assess syntactic processing in language comprehension in aging. This test aims to help in the diagnosis of Mild Cognitive Impairment (MCI), a condition that can progress to Alzheimer s Disease (AD). Thus, the early diagnosis of cognitive impairment in aging can offer a better prognosis for the patient, based on medical follow-up and neuropsychological rehabilitation. It is known that one that greatest risk factor for AD is advancing age. This research is very relevant because the world population has been aging at an accelerated pace and because there is a huge lack of an assessment instrument aimed at syntactic processing in aging, mainly due to the lack of a test in Brazilian Portuguese. A systematic review carried out on the PubMed, LILACS and SciELO platforms revealed that over the last 5 years very few studies have evaluated the syntactic processing of patients with MCI. And the number of studies that considered the processing of syntactically complex sentences is even smaller. Therefore, in this work, we present a prototype of a test of comprehension of sentences that vary in level of syntactic complexity, developed on the basis of research in the fields of Psycholinguistics and Clinical Neuropsychology. It is a sentence-picture matching task, in which participants must evaluate the correspondence between the sentence and the correct illustration. This test explores the comprehension of sentences with subject and object relative clause; subject and object interrogatives; sentences with subject and object topicalization; reversible (implausible and neutral) and irreversible passive sentences; structures with perspective verb; and reversible and irreversible active sentences. As the literature reports, even in healthy aging, a decline in the processing of more complex syntactic structures is expected, which entail greater cognitive demand. In a context of unhealthy aging, this decline would be more accentuated and evident. Therefore, this test can be a promising measure in the detection of a MCI that affects the language domain. A pilot study was conducted with a group of 43 younger adults and a group of 10 elderly people without cognitive impairment, to evaluate the functionality of the developed test. Both groups performed the image identification task without difficulties, with a similar average time and a low percentage of errors, which occurred with the most complex structures of the set of the examined sentences. Therefore, the pilot study results suggest that the test can be a sensitive measure in the evaluation of syntactic processing in sentence comprehension by adults and the elderly.

Our lives become longer with new advancements in medicine and technology. As a result, cognition and memory impairments will become a growing concern[23]. To be able to treat cognitive decline, dementia and related diseases, the need for early detection of memory deficiencies increases. This study aimed to validate the use of a new digital interaction version of a common memory test, the Rey Auditory Verbal Learning Test (RAVLT), compared with norm from the traditional human-to-human interaction version of the same test. This was performed through userstudies with both test versions in a counterbalanced order. The results consisted of quantitative results from the tests together with qualitative data from interviews with the participants in connection to each test occasion. The results showed a slight difference in some aspects of the quantitative test results, but at the same time, no significant difference for most of the measured results. Further, the interviews demonstrated that the differences in interaction and experience between the versions of the tests could be the reason for some of the differences in the quantitative result. The conclusion from this study was that there are many difficult problems to solve for speech interfaces in neurocognitive tests like the RAVLT. In line with previous research [22], the results highlight the importance of a natural speech interaction that conforms with the basic principles of human conversation, to create a stress-free experience and test results that can be reliable and comparable.

Recent research show that young people with mild intellectual disabilities are raising complaints against the society´s demand for categorization in order to provide the right amount of support (Ineland, Molin & Sauer 2013, Tideman 2012). This study’s purpose is to find out if and how students attending a senior high school for people with intellectual disability, are affected by their school attendance in their identity making. With focus on finding out:1.What situations within the school prove specific importance in relation to students’ identity making?2.How are the students identity making limited or enabled by their attendance at the school for students with intellectual disabilities? 3.How are the students identity making affected by being included or excluded?The theoretical framework is inspired by theories based on social constructionism. The author has chosen to adopt an intersectional analysis that claims that different power relations in society affects and reinforce each other. Another important theory is social identity theory and representations theory. These theories explain how social identity is created in the relation between the individual and the social world that she exists in. The empirical material was collected through interviews with six students currently attending a senior high school for people with intellectual disability, “gymnasiesärskola” in Swedish. The results show that the specific situations that proved importance for the student’s identity making were: When they were not being able to make choices. How other people, especially teachers, were relating to them combined with the social climate in groups they belonged to. And the overall sense of not being “normal” and having a diagnosis. Results that appeared to be new compared to other studies were that the students interpreted their diagnosis as a school issue and not something that was connected to their own person.

Background: To reduce the reliance on clinical judgment for the regulation of sports-related traumatic brain injury, identifying and measuring objective to biofluid biomarkers can provide important insight into the diagnosis (Determining the type and origin of a disorder) and prognosis (Determining the chance of survival of a disorder) of SR-TBIs. A biomarker is a qualitative or quantitative measurement that provides a measure of a subject’s physiological or pathological condition at a specific time or during a disease state. Recent literature has suggested that biomarkers can help in the screening of patients exhibiting symptoms of mild traumatic brain injury (mTBI). Despite insights from recent research, it is not clear whether biomarkers and assessments of sports-related TBI are well-aligned. The objective of this study sought to review the current literature on predictive values of biomarkers: glial fibrillary acidic protein (GFAP), calcium channel binding protein S100 subunit beta (S100β), total-tau and neuron-specific enolase (NSE) for sports-related Traumatic Brain Injuries (SR-TBIs) to improve comprehension of biological and clinical contexts that can help evaluate the use of these biomarkers in sports-related TBIs and their potential function. Methods: The study was reported based on guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA: 2020 Edition) of 8 studies related to the assessment of biomarkers concerning SR-TBI. Literature searches were carried out on PubMed, Google Scholar, ScienceDirect, and ResearchGate. With an evidentiary table, the characteristics of the studies included in the meta-analysis (n = 14 studies) were presented. A significant role for biomarkers in the management of mild traumatic brain injury is suggested by the results of this analysis. From the literature, the significance of biomarkers in SR-TBI was identified along with the biomarkers that can facilitate more accurate clinical decision-making. Results:The initial search resulted in 73 articles, and the application of exclusion criteria and removal of duplicates resulted in the inclusion of 14 articles. Eight of the included studies were ([26], [27], [28], [30], [34], [39], [40], [41]), three were cohort studies ([25], [37], [45]) one was a pilot study [32], one interview, and an observational study [44]. The review was carried out to determine the efficacy of Biomarkers GFAP, S100β, Total-tau, and NSE to help in the screening of mild traumatic brain injury (mTBI) in patients showing symptoms. The focus is on athletes presenting at an emergency department with possible mTBI requiring a CT scan based on the application of a clinical algorithm. A forest plot was utilized, and the studies had low heterogeneity or variability (P Conclusions: It was established that the utility of biofluid biomarkers in the prediction of mild traumatic brain injury due to SRC is significant when the markers are used in large combinations. The four biofluid biomarkers (S100β, total-tau, GFAP, NSE) under study have strong predictive ability for mTBI, and their use can reduce the number of CT scans among TBI patients participating in athletic activities. Although preliminary evidence shows that other diagnostic treatments may help to mitigate traumatic brain injury sequelae, clinical trials are needed to further test their efficacy, specifically with diverse and high-risk populations. Luckily, the research on mTBI biomarkers is rapidly advancing, and should these biomarkers be better established clinically, they could easily hold many important roles.

The accuracy of neuropsychological assessment is critical in the diagnosis of cognitive impairments in older adults. However, existing neuropsychological tests may not be suitable for minority populations. This thesis aimed to address this issue by recruiting cognitively-healthy South Asian older adults and assessing cognitive function in this group. Results showed that typically used assessments, despite being translated, were not suitable for this cohort. Furthermore, skills required for test completion such as mathematics and writing/hand dexterity (which are related to education levels) influenced test scores. Therefore, new assessments of general cognitive function and associative memory were developed to improve the accuracy of neuropsychological test scores. The new tests were not affected by education and they achieved high internal and test re-test reliability. Time of day (TOD) that testing takes place is also known to affect cognition. Interestingly, no TOD effects were observed in this cohort. It was hypothesised that engagement in the daily five Islamic prayers may have contributed to this lack of a TOD effect. However, the results did not confirm this. The thesis then looked at overall prayer engagement and cognition. Results showed that engagement in the daily five prayers and Quran recitation significantly increased scores on assessments of processing speed. This thesis demonstrates that accurately assessing cognition in South Asian older adults is challenging and that the cognitive tests used must be suitable for this cohort. Interesting findings emerged for prayer engagement which may have wider implications for the field of cognitive reserve.
