ABSTRACT

ABSTRACT. The COVID-19 pandemic has shown the need for neuropsychological care for older adults with memory complaints in different contexts, including rural areas or areas with difficult access. Objective: This study aimed to analyze the clinical utility of the Phototest, through telemedicine, to identify mild cognitive impairment in rural older adults with memory complaints, during the COVID-19 pandemic. Methods: We performed a cross-sectional, case-control, and clinical utility comparison of brief cognitive tests (BCTs). The sample included 111 rural elderly people with mild cognitive impairment (MCI) and 130 healthy controls from the Los Lagos region, Chile. The instruments adopted were modified Mini-Mental State Examination (MMSEm) and adapted version of the Phototest (PT) for Chile. Results: To identify mild cognitive impairment, using a cutoff score of 27-28 points, the Phototest showed a sensitivity of 96.6% and a specificity of 81.8%; indicators superior to those of the MMSEm. Conclusions: The Phototest is more accurate than the MMSEm in identifying cognitive alterations in rural older adults with cognitive memory complaints through telemedicine. Therefore, its use in primary care is recommended in order to perform early detection of preclinical cognitive alterations in mild cognitive impairment or neurodegenerative diseases.


RESUMO. A pandemia de COVID-19 mostrou a necessidade de cuidados neuropsicológicos para adultos idosos com queixas de memória em diferentes contextos, incluindo áreas rurais ou áreas de difícil acesso. Objetivo: Analisar a utilidade clínica do Phototest, por meio da telemedicina, para identificar uma leve deficiência cognitiva em adultos idosos rurais com queixas de memória, durante a pandemia de COVID-19. Métodos: Realizamos uma comparação transversal, caso-controle e utilidade clínica dos testes cognitivos breves. Amostra: Cento e onze idosos rurais com deficiência cognitiva leve (DCL) e 130 controles saudáveis da região de Los Lagos, Chile. Instrumentos: Minimental modificado (MMSEm) e versão do teste fotográfico (PT) adaptada para o Chile. Resultados: Para identificar a DCL, usando pontuação de corte de 27-28 pontos, o Phototest mostrou sensibilidade de 96,6% e especificidade de 81,8%; indicadores superiores aos do MMSEm. Conclusões: O Phototest é mais preciso que o MMSEm para identificar, por meio da telemedicina, alterações cognitivas em adultos idosos rurais com queixas de memória cognitiva. Sendo assim, seu uso na atenção primária é recomendado para realizar a detecção precoce de alterações cognitivas pré-clínicas em DCL ou doenças neurodegenerativas.

ABSTRACT

Resumen La batería neuropsicológica UDS (del inglés Uniform Data Set), se usa a nivel mundial para homogeneizar las investigaciones de enfermedad de Alzheimer. Objetivo: Sintetizar cuantitativamente los resultados de las subpruebas de la UDS, para perfil cognitivo de controles, pacientes con deterioro cognitivo leve y demencia de tipo Alzheimer. Método: Se realizó una búsqueda sistemática avanzada y manual en bases de datos (PubMed/ MedLine, Web Of Science, Scopus, Lilacs, Science Direct, Cochrane Library, PsycINFO) para evaluar el rendimiento diagnóstico de la UDS. Resultados: La revisión sistemática, mostró una sintesís narrativa donde se analizaron 8 artículos que incluyeron 9260 sujetos, con un rango de edad entre 60 y 90 años. La síntesis cuantitativa utilizó 13 artículos con una muestra total de 2.884 participantes, con una edad promedio de 74 años y una media de 15 años de educación. Conclusión: Se describió una síntesis de las puntuaciones mediales, que generan puntos de corte para demencia tipo alzheimer (DTA), deterioro cognitivo leve (DCL) y controles cognitivamente normales, evidenciando una adecuada precisión diagnóstica.


Abstract The neuropsychological battery UDS (of the English Uniform Data Set), is used worldwide to homogenize the investigations of Alzheimer's disease. Objective: Quantitatively synthesize the results of the subtests of the UDS for the cognitive profile of controls, patients with mild cognitive impairment and dementia of the Alzheimer type. Method: An advanced and manual systematic search was performed in databases (PubMed / MedLine, Web of Science, Scopus, Lilacs, Science Direct, Cochrane Library, PsycINFO) evaluating the diagnostic performance of the UDS. Results: The systematic review showed a narrative synthesis where 8 articles were included that included 9260 subjects, with an age range between 60 and 90 years. The quantitative synthesis used 13 articles with a total sample of 2,884 participants, with an average age of 74 years and an average of 15 years of education. Conclusion: We described a synthesis of the medial scores, which generate cut-off points for Alzheimer's type dementia (DTA), mild cognitive impairment (MCI) and cognitively normal controls, evidencing an adequate diagnostic precession.
