Resumo: | Diffuse axonal injury (DAI) is a microscopic injury caused by a rotational acceleration of the head, the result of a traumatic brain injury (TBI), and is associated with high levels of morbidity and mortality. Researchers have studied the origin of verbal memory deficits in this population. This study aims at analyzing the relation between the different measures of verbal memory performance (immediate memory, deferred memory, learning progress, and percentage of retention) of patients with DAI. To this end, 14 adult patients with CMRRC-RP DAIs were collected, who willingly performed one of the following tests: Logic Memory I and II (ML) of the Wechsler Memory Scale -III (WMS-III), or the Auditory Verbal Learning Test (AVLT). Pearson's and Ponto-Bisserial's correlation coefficients were performed, and the results showed significant correlations between sex and the immediate memory variable (rpb=-.63, p=.008) in addition to the correlations between the variables immediate memory and the evolution of learning (r=.73, p=.003), immediate memory and deferred memory (r=.91, p=.000), immediate memory and the percentage of retention (r=.81, p=.003), deferred memory and the evolution of learning (r=.88, p=.000), deferred memory and the percentage of retention (r=.95, p=.000), and finally evolution of learning and the percentage of retention (r=.78, p=.005). Contrary to expectations, the results showed no significant correlations between these variables and the clinical variables; GCS score and coma time. In general, it was possible to infer that the four dependent variables correlate with each other, which means that the performance of patients with DAI in one of these variables will influence their performance in the others, because the stages of the memory process are correlated. If primary phases of the memory process fail, subsequent ones will not be successful, resulting in poor verbal memory performance. |

Investigadores têm estudado a origem dos défices de memória verbal nesta população. A presente investigação objetiva analisar a relação entre as diferentes medidas de desempenho de memória verbal (memória imediata, memória diferida, evolução da aprendizagem e percentagem de retenção) de doentes com LAD. Para tal foram recolhidos 14 doentes adultos com LAD do CMRRC-RP, os quais realizaram uma das seguintes provas: Memória Lógica I e II (ML) da Escala de Memória de Wechsler-III (WMS-III) ou o teste de Aprendizagem Audio-Verbal de Rey (RAVLT). Foram realizados coeficientes de correlação de Pearson e de Ponto-Bisserial e os resultados mostraram correlações significativas entre o sexo e a variável memória imediata (rpb=-.63, p=.008), bem como correlações entre as variáveis memória imediata e a evolução da aprendizagem (r=.73, p=.003), memória imediata e a memória diferida (r=.91, p=.000), memória imediata e a percentagem de retenção (r=.81, p=.003), memória diferida e a evolução da aprendizagem (r=.88, p=.000), memória diferida e a percentagem de retenção (r=.95, p=.000) e por fim, evolução da aprendizagem e a percentagem de retenção (r=.78, p=.005). Ao contrário do esperado, os resultados não mostraram correlações significativas entre estas variáveis e as variáveis clínicas pontuação da GCS e tempo de coma. De uma forma geral, foi possível inferir que as quatros variáveis dependentes correlacionam-se entre si, o que significa que o desempenho dos doentes com LAD numa destas variáveis influenciará o seu desempenho nas restantes. Isto acontece uma vez que as fases do processo de memória estão relacionadas. Se fases mais primárias do processo de memória falharem, as posteriores não irão obter sucesso, refletindo-se em fracos desempenhos de memória verbal.2020-05-27T13:20:16Z2019-12-13T00:00:00Z2019-12-13info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/28589engMartins, Cátia Daniela Pintoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:55:18Zoai:ria.ua.pt:10773/28589Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:01:05.740458Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
