Enhancing Immediate Memory, Potential Learning, and Working Memory with Transcranial Direct Current Stimulation in Healthy Older Adults.

BACKGROUND: Transcranial direct current stimulation (tDCS) has emerged as a prevention method or minimizer of the normal cognitive deterioration that occurs during the aging process. tDCS can be used to enhance cognitive functions such as immediate memory, learning, or working memory in healthy subjects. The objective of this study was to analyze the effect of two 20-min sessions of anodal transcranial direct stimulation on immediate memory, learning potential, and working memory in healthy older adults. METHODS: A randomized, single-blind, repeated-measures, sham-controlled design was used. The sample is made up of 31 healthy older adults, of whom 16 were in the stimulation group and 15 were in the sham group. The anode was placed on position F7, coinciding with the left dorsolateral prefrontal cortex region, and the cathode was placed on Fp2, the right supraorbital area (rSO). RESULTS: When comparing the results of the treatment group and the sham group, differences were observed in working memory and learning potential; however, no differences in immediate memory were found. CONCLUSION: The results showed that tDCS is a non-invasive and safe tool to enhance cognitive processes in healthy older adults interested in maintaining some cognitive function.

Mindfulness-based Cognitive Therapy to Improve Sleep Quality in Older Adults with Insomnia

There is a high prevalence of insomnia in older adults, which has negative consequences for their well-being and quality of life. The recommendation for first-line treatments is to administer non-pharmacological interventions. The objective of this research was to verify the effectiveness of Mindfulness-Based Cognitive Therapy in older adults with subclinical and moderate insomnia, studying its impact on sleep quality. One hundred and six older adults participated and were assigned to the subclinical insomnia (n = 50) or moderate insomnia (n = 56) groups; subsequently, they were randomly assigned to the control and intervention groups. Subjects were evaluated at two times with the Insomnia Severity Index and the Pittsburgh Sleep Quality Index. Significant results were obtained on both scales, with a reduction in insomnia symptoms in the subclinical and moderate intervention groups. The administration of a treatment that combines mindfulness and cognitive therapy is effective for treating insomnia in older adults. (AU)

Existe una alta prevalencia de insomnio en los adultos mayores, lo que tiene consecuencias negativas para su bienestar y calidad de vida. La recomendación para los tratamientos de primera línea es administrar intervenciones no farmacológicas. El objetivo de esta investigación fue verificar la efectividad de la terapia cognitiva basada en mindfulness en adultos mayores con insomnio subclínico y moderado, estudiando su impacto en la calidad del sueño. Participaron 106 adultos mayores que fueron asignados a los grupos de insomnio subclínico (n = 50) o de insomnio moderado (n = 56); posteriormente, fueron asignados aleatoriamente a los grupos de control y de intervención. Los sujetos fueron evaluados antes y después de la intervención con el índice de gravedad del insomnio y el índice de calidad del sueño de Pittsburgh. Se obtuvieron resultados significativos en ambas escalas, con una reducción de los síntomas de insomnio en los grupos de intervención subclínica y moderada. La administración de un tratamiento que combina mindfulness y terapia cognitiva es eficaz para tratar el insomnio en adultos mayores. (AU)

La desesperanza como predictora de la soledad en adultos mayores / Hopelessness as a predictor of loneliness in older adults

Antecedentes y objetivo: La desesperanza se caracteriza por un conjunto de esquemas cognitivos negativos sobre el futuro, conceptualizándose en base a 3 dimensiones: afectiva, motivacional y cognitiva. Este constructo se encuentra vinculado a la soledad cuya incidencia en adultos mayores es cada vez más alta. El objetivo de esta investigación es comprobar si los factores de desesperanza predicen los niveles de soledad en adultos mayores.Material y método: Participaron 138 personas no institucionalizados de la ciudad de Valencia con edades entre los 65 y 90 años, y con una edad media de 73,67 (DE=4,8), siendo el 59,4% mujeres. Se aplicó para evaluar a los participantes la escala de desesperanza de Beck (BHS) y la escala de soledad de la Universidad de California (UCLA).Resultados: Los factores motivacional y cognitivo actúan como predictores estadísticamente significativos de la soledad, mientras que el factor afectivo no se presenta como un factor significativo. El modelo final obtuvo una R2adj=0,442, F(3, 87)=23,97; p<0,001.Conclusiones: La soledad es un fenómeno de gran preocupación en el ámbito de la gerontología debido a su alta incidencia y repercusión. Los resultados señalan que la desesperanza, concretamente la pérdida de motivación y las expectativas negativas sobre el futuro, son cuestiones críticas para el desarrollo de sentimientos de soledad en los adultos mayores. De este modo, resulta relevante atender a estas variables para poder aplicar programas de prevención de la soledad. (AU)

Background and objective: Hopelessness is characterized by a set of negative cognitive schemas about the future, conceptualized on the basis of three dimensions: affective, motivational and cognitive. This construct is linked to loneliness, the incidence of which in older adults is increasingly high. The aim of this research is to test whether hopelessness factors predict levels of loneliness in older adults.Material and methods: 138 non-institutionalized persons from Valencia city between 65-90 years old participated, with a mean age of 73.67 (SD=4.8), and 59.4% were women. The Beck Hopelessness Scale (BHS) and University of California Los Angeles Loneliness Scale (UCLA) were administered to assess participants.Results: The motivational and cognitive factors acted as statistically significant predictors of loneliness, while the affective factor was not presented as a significant factor. The final model obtained an R2adj=.442, F(3, 87)=23.97, p<.001.Conclusions: Loneliness is a phenomenon of great concern in the field of gerontology due to its high incidence and impact. The results indicate that hopelessness, specifically loss of motivation and negative expectations about the future, are critical issues for the development of feelings of loneliness in older adults. Thus, it is relevant to pay attention to these variables in order to apply loneliness prevention programs. (AU)

A Longitudinal Study of Episodic and Semantic Autobiographical Memory in aMCI and Alzheimer's Disease Patients.

BACKGROUND: The main objective of this study was to analyze the evolution of autobiographical memory (both episodic and semantic) in patients with mild cognitive impairment, patients with Alzheimer's disease, and a healthy control group. We compared these groups at two time points: first, at baseline, and in a follow-up after 18 months. METHOD: Twenty-six healthy older adults, 17 patients with mild amnestic cognitive impairment, and 16 patients with Alzheimer's disease, matched on age and educational level, were evaluated at both time points with the Autobiographical Memory Interview. RESULTS: The results showed significant longitudinal deterioration in episodic and semantic autobiographical memory in patients with mild cognitive impairment and in patients with Alzheimer's disease, but not in healthy older adults. CONCLUSIONS: The deterioration of episodic and semantic autobiographical memory in AD is confirmed; however, although the episodic was impaired in aMCI, a pattern that evolved toward deterioration over a period of eighteen months was observed for the semantic autobiographical memory.
