“…además de los factores psicológicos y neurobiológicos recién revisados, los antecedentes teóricos y empíricos, dan cuenta también, de variables sociodemográficas y experiencias de vida que influenciarían el funcionamiento cognitivo de los adultos mayores (Brewster et al, 2014).…”

“…en este contexto glymour y Manly (2008), plantean que circunstancias vitales de la temprana y mediana edad, podrían modificar el funcionamiento cognitivo en la adultez mayor, por la influencia de los patrones de estilo de vida, los que a su vez se correlacionan de manera directa con el nivel socioeconómico, variable que se asocia al nivel educativo y la etnia, resultando complejo delimitar el real influjo de cada variable (Brewster et al, 2014).…”

“…Diferentes investigaciones han detectado asociaciones positivas entre el envejecimiento cognitivo y el nivel educativo, concluyendo que la calidad y la duración de la escolarización influyen de manera directa en el funcionamiento cognitivo global y en la reserva cognitiva (allegri et al, 2010); Brewster et al, 2014). Un estudio reciente realizado por Meléndez -Moral y su equipo (2012) concluyó que los sujetos con más edad y menos años de escolarización, tienen mayor riesgo de cumplir con los criterios de inclusión para el diagnóstico de Dcl; su muestra estuvo constituida por sujetos de entre 60 y 89 años de edad.…”

“…otras variables que han sido exploradas en su relación con el funcionamiento cognitivo, son las actividades recreativas y de ocio (Brewster et al, 2014). Un estudio inicial acerca del riesgo de Demencia desarrollado en china, demostró que las actividades comunitarias y recreativas, como la jardinería, eran un factor protector en la incidencia de demencia (Zhang y Zhang, 1999).…”

“…Buscando una mayor precisión en la comprensión del funcionamiento cognitivo, Brewster et al, (2014) realizó un estudio longitudinal en el que se examinó la influencia de las experiencias de vida y los factores demográficos en el funcionamiento cognitivo de adultos mayores. ellos encontraron que la edad, la alfabetización, el nivel socioeconómico en la niñez, y la actividad física, tienen una influencia significativa en el funcionamiento cognitivo (Brewster et al, 2014).…”

Resumeneste artículo presenta una breve reseña sobre el Deterioro cognitivo leve en adultos mayores, considerando los principales precursores que anuncian, y los factores de riesgo que aceleran los procesos de envejecimiento cognitivo, los cuales aumentan la probabilidad de recibir un diagnóstico de Dcl. a su vez, la presencia de Dcl aumenta el riesgo y eventual tránsito hacia la demencia, especialmente la demencia de tipo alzheimer. por otra parte, en el artículo se describen las diferentes modalidades de presentación del deterioro cognitivo, revisando también el Dcl asociado a la sintomatología depresiva, a la enfermedad de parkinson y otras enfermedades degenerativas del sNc. la presente revisión, permite dar cuenta de hallazgos recientes y relevantes con relación a la disfunción cognitiva en adultos mayores, quienes representan una proporción cada vez mayor de la población nacional y mundial. Palabras clave: envejecimiento, deterioro cognitivo leve, indicadores tempranos, demencia Abstract this article presents a brief overview of mild cognitive impairment in older adults, considering its main anticipating precursors, and the risk factors that may accelerate the processes of cognitive aging, which increases the likelihood of being diagnosed with Mci. in turn, the presence of Mcl increases the risk and eventual transition to dementia, particularly alzheimer's dementia. Moreover, the article describes the different forms cognitive impairment may present itself, and also reviews MCI associated with depressive symptoms, parkinson's disease and other degenerative diseases of the cNs. this revision accounts for recent and relevant findings regarding cognitive dysfunction in the elderly, who represent a growing share of national and global populations.

ImportancePhysical activity is associated with the risk for cognitive decline, but much of the evidence in this domain comes from studies with short follow-ups, which is prone to reverse causation bias.ObjectiveTo examine how length of follow-up, baseline age, physical activity amount, and study quality modify the longitudinal associations of physical activity with cognition.Data SourcesObservational studies of adults with a prospective follow-up of at least 1 year, a valid baseline cognitive measure or midlife cohort, and an estimate of the association of baseline physical activity and follow-up cognition were sought from PsycInfo, Scopus, CINAHL, Web of Science, SPORTDiscus, and PubMed, with the final search conducted on November 2, 2022.Study SelectionTwo independent researchers screened titles with abstracts and full-text reports.Data Extraction and SynthesisTwo reviewers independently assessed study quality and extracted data. Pooled estimates of association were calculated with random-effects meta-analyses. An extensive set of moderators, funnel plots, and scatter plots of physical activity amount were examined. This study is reported following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.Main Outcomes and MeasuresPooled estimates of the associations between physical activity and global cognition, as well as specific cognitive domains, were examined.ResultsA total of 104 studies with 341 471 participants were assessed. Analysis of binary outcomes included 45 studies with 102 452 individuals, analysis of follow-up global cognition included 14 studies with 41 045 individuals, and analysis of change in global cognition included 25 studies with 67 463 individuals. Physical activity was associated with a decreased incidence of cognitive impairment or decline after correction for funnel plot asymmetry (pooled risk ratio, 0.97; 95% CI, 0.97-0.99), but there was no significant association in follow-ups longer than 10 years. Physical activity was associated with follow-up global cognition (standardized regression coefficient, 0.03; 95% CI, 0.02-0.03) and change in global cognition (standardized regression coefficient, 0.01; 95% CI, 0.01 to 0.02) from trim-and-fill analyses, with no clear dose-response or moderation by follow-up length, baseline age, study quality or adjustment for baseline cognition. The specific cognitive domains associated with physical activity were episodic memory (standardized regression coefficient, 0.03; 95% CI, 0.02-0.04) and verbal fluency (standardized regression coefficient, 0.05; 95% CI, 0.03-0.08).Conclusions and RelevanceIn this meta-analysis of the association of physical activity with cognitive decline, physical activity was associated with better late-life cognition, but the association was weak. However, even a weak association is important from a population health perspective.

Introduction: Earlier studies of the effects of childhood socioeconomic status (SES) on later-life cognitive function consistently report a social gradient in later-life cognitive function. Evidence for their effects on cognitive decline is, however, less clear. Methods:The sample consists of 5324 participants in the Whitehall II study, 8572 in the Health and Retirement Study (HRS), and 1413 in the Kame Project, who completed self-report questionnaires on their early life experiences and underwent repeated cognitive assessments. We characterized cognitive trajectories using latent class mixed models, and explored associations between childhood SES and latent class membership using logistic regressions. Results:We identified distinct trajectories classes for all cognitive measures examined.Childhood socioeconomic deprivation was associated with an increased likelihood of being in a lower trajectory class.Discussion: Our findings support the notions that cognitive aging is a heterogeneous process and early life circumstances may have lasting effects on cognition across the life-course.
