Crucigrams vs. videojuegos: cuál es la mejor practica para prevenir la pérdida de la memorya

En los adultos mayores, el Deterioro cognitivo leve (DCL) confere un major riesgo de progression a la dementia, particularly a la enfermedad de Alzheimer’s. Es habitual que, en este sentido, se recomiende el uso de practica que exijan la agudeza cerebral como una estrategia posible para prevenir esos efectos.

Sin embargo, para la ciencia the effectiveness of cognitive training in patients in the beginnings of certain cognitive loss was not clearly determined. Now a new study carried out jointly by more than a dozen researchers from the University of Columbia and the University of Duke published in the magazine NEJM Evidence mostró que hacer crucigrams tiene una vantagea sobre los videojuegos de computadora para el funcción de la memorya in adultos mayores con deterioro cognitivo leve.

In a randomized controlled trial, led by Davangere P. Devanand, professor of psychiatry and neurology at Columbia, with Murali Doraiswamy, professor of psychiatry and medicine at Duke, they determined that the participants (with an average age of 71 years) trained to hacer prácticas estimulantes para la cognition.

“Este es el primer estudio que documenta los beneficios tanto corto como largo plazo del entrenamiento de crucigramas en el hogar en comprásiona con otra intervention. “Los resultados son importantes in light of the difficulty to show improvements with interventions in mild cognitive impairment,” explained Devanand, who oversees research on cerebral aging and mental health in Colombia.

Los crucigramas se usan y recomienda muy habitualmente para mantener activo el cerebropero no se habian estudiado systematicamente en el deterioro cognitivo leve.

To carry out their study, the researchers randomly assigned 107 participants with mild cognitive impairment (DCL) in two different sites to training with crosswords or cognitive games with intensive training for 12 weeks followed by reinforcement sessions of up to 78 weeks.

Both interventions were delivered through a computerized platform with weekly compliance monitoring. The findings were “surprising”, according to the specialists. Los crucigramas fueron superiores a los juegos cognitivos en la medida de resultado cognitiva primaria, ADAS-Cog, tanto a las 12 semanas como a las 78 semanas. También lo fueron en las preguntas frecuentes, una medida del funcción diario, a las 78 semanas.

La contracción del cerebro (medida con MRI) fue menor para los crucigramas a las 78 semanas. “The benefits were observed not only in cognition but also in daily activities with indications of cerebral contraction in magnetic resonance, which suggests that the effects are clinically significant,” explained Devanand.

The studio also highlighted the importance of commitment. Based on remote electronic monitoring of computer use, participants in a later stage of disability can be more involved with more familiar crosswords than with computerized cognitive games.

Two strong points of the trial were the rate of participation of 28% of persons from minority ethnic groups and the low rate of abandonment (15%) for a long trial at home. One limitation of the study was the absence of a control group that did not receive cognitive training.

Si bien estos resultados son muy alentadores, los autores emphasisan la necessidad de replicar en un ensayo controlado más grande con un grupo de controlo inactivo. “La conjunción de tres potencialidades que implica mejorar la cognición, la función y la neuro protección es el Santo Grail para este campo de estudio. “Additional research to scale up cerebral training as a digital therapy in the home to delay Alzheimer’s should be a priority for this area of ​​work”, concluded Doraiswamy.
