Declive cognitivo de atención y memoria en adultos mayores sanos
Bibliographic record
Abstract
RESUMEN: Las funciones cognitivas que declinan normalmente durante el envejecimiento son la atencion y la memoria, una deteccion temprana podria disminuir su deterioro a pesar del avance de los anos. El objetivo es evaluar el declive cognitivo de las funciones de memoria y atencion en el proceso de envejecimiento normal en diferentes edades. Se seleccionaron tareas de memoria y atencion de las escalas “NEUROPSI” y de Montreal Cognitive Assesment “MOCA”. Se evaluaron 186 adultos mayores sanos, con una edad promedio de 61.14 anos, distribuidos en 4 grupos de acuerdo con la edad. Las tareas de mayor sensibilidad que declinan durante el envejecimiento normal fueron para la memoria T2, T3, T4 y las de atencion: T9, T10 y T12. El grupo de mayor edad G4-75 a 85 anos presento bajos puntajes en la realizacion de las tareas, existiendo diferencias estadisticamente significativas entre los diferentes grupos de edad, demostrando la existencia de una disminucion de atencion y memoria conforme avanza la edad. Palabras Clave: Funciones Cognitivas; Envejecimiento Normal; Adultos Mayores; Declive Cognitivo. ABSTRACT The cognitive functions that normally decline during aging are attention and memory, early detection could decrease its deterioration despite the advance of years. The objective is to assess the cognitive decline of the functions of memory and attention in the process of normal aging at different ages. Memory and attention tasks were selected from the NEUROPSI and the Montreal Cognitive Assessment MOCA scales. The tasks of greater savings decline during normal aging were for T2, T3, T4 memory and attention: T9, T10 and T12. The Group of older G4-75 to 85 years had low scores in the accomplishment of the tasks, there are statistically significant differences between different age groups, demonstrating the existence of a decrease in attention and memory as advancing age. Key words: Cognitive Functions; Normal Aging; Older Adults; Cognitive Decline. RESUMO As funcoes cognitivas que declinam normalmente durante o envelhecimento sao a atencao e a memoria, uma deteccao precoce pode diminuir a sua deterioracao apesar do avanco dos anos. O objetivo e avaliar o declinio cognitivo das funcoes de memoria e atencao no processo de envelhecimento normal em diferentes idades. Foram selecionadas tarefas de memoria e atencao das escalas “NEUROPSI” e de Montreal Cognitive Assesment “MOCA”. Foram avaliados 186 adultos idosos saudaveis, com uma idade media de 61.14 anos, distribuidos em 4 grupos de acordo com a idade. As tarefas de maior sensibilidade que declinam durante o envelhecimento normal foram para a memoria T2, T3, T4 e as de atencao: T9, T10 e T12. O grupo de maior idade G4-75 a 85 anos apresentou baixas pontuacoes na realizacao das tarefas, existindo diferencas estatisticamente significativas entre os diferentes grupos etarios, demonstrando a existencia de uma diminuicao de atencao e memoria a medida que avanca a idade. Palavras-chave: Funcoes cognitivas; Envelhecimento Normal; Adultos mais velhos; Declinio cognitivo

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
