Cognitive plasticity is a topic of interest since it allows us to analyse the potential cognitive modifiability of a person. Previous research has demonstrated the existence of plasticity in old age [Baltes, P. B. (1987). Theoretical propositions of life-span developmental psychology: On the dynamics between growth and decline. Developmental Psychology, 23(5), 611-626] regardless of presence or absence of cognitive deterioration [Calero, M. D., & Navarro, E. (2004). Relationship between plasticity, mild cognitive impairment and cognitive decline. Archives of Clinical Neuropsychology, 19, 653-660]. In this context, the present study was designed to analyse the presence of plasticity in elderly persons who seemed to present cognitive deterioration, and to explore the relation between cognitive plasticity and the results obtained from a memory training programme. One hundred and thirty-three elderly persons participated in the study and were evaluated by means of a cognitive plasticity test (Position test) and various tests for measuring the effects of the training. Part of the elderly population received the memory training, whose effects were measured immediately after the training and again after 9 months. The results demonstrate that the programme significantly improves cognitive performance, while plasticity is shown to be an important modulating variable on the improvement achieved.

A topic of great interest in gerontology research is the prediction of cognitive deterioration which marks the transition from mild cognitive impairment (MCI) to dementia. In this area the term plasticity is a construct of prime importance. Previous studies have demonstrated the existence of plasticity in healthy older persons, and it is thought that this is what discriminates between healthy individuals and those at risk for dementia. The aim of the present study is to demonstrate that plasticity exists in persons with MCI, and that a lack of plasticity may be one of the risk factors related to cognitive decline. An adapted version of the Auditory Verbal Learning Test-the AVLT of Learning Potential-was used to assess plasticity. Participants in the research were 203 older persons whose cognitive status had previously been determined using a cognitive screening test. The results show that plasticity exists in persons with MCI and that its presence is associated with less marked cognitive decline.

The purpose of this study was to validate a reduced version (15 items) of the Boston Naming Test (BNT) in a sample of 78 low-educational elderly persons with or without dementia, as determined by independent assessment with a battery of cognitive tests. The reduced version was found to be equivalent to the complete BNT, and to have criterion validity with respect to other measures of dementia. We conclude that the reduced version is a useful instrument for assessing patients who require shorter testing methods because of severe cognitive deterioration or their low level of education.
(1) Introduction: With older adults, cognitive intervention programs are most often used for preventing or reversing a decline in cognitive functions, but it has been recently noted that there are insufficient high-quality research studies that report the effects of cognitive intervention on the cognitive functioning of older adults. (2) Objective: To analyze the available evidence concerning the effect of cognitive interventions for improving or maintaining the general cognitive status of older adults who present different cognitive levels. (3) Method: a review of studies published between 2010 and 2019 using the following databases: PubMed, PsycINFO, Cochrane, Google Scholar, ProQuest and Medline. (4) Results: We selected 13 systematic reviews and/or meta-analyses. The results showed that the cognitive intervention programs improved general cognitive functioning and specific cognitive functions regardless of the initial cognitive level; that cognitive decline was slowed in older persons with dementia; and there was improvement in activities of daily living. Regarding duration of the results, benefits were maintained for periods of 2 months to 5 years. (5) Conclusion: Cognitive interventions have proven effective for maintaining and/or improving cognitive functioning in older adults regardless of their initial cognitive status. Even so, there are few studies that follow up these results to see whether they are maintained in the long term and whether there is transfer to other skills of daily life. However, we were able to observe in the present review how the participants’ cognitive level varied according to sociodemographic differences, and to identify which components of cognitive programs make them more effective. Based on the results found, we highlight the importance of designing cognitive intervention programs that meet these effectiveness criteria, in order to maximize the positive effects of such programs when working with a population of older adults.
Objectives: To study changes in the cognitive status and dependency of patients aged over 65 years during hospitalization for bone fracture and how these changes relate to the total number of days of admission and absolute rest during hospitalization. Along with cognitive decline, musculoskeletal disorders are considered key factors in this patient population. As well as requiring hospital admission and/or surgical treatment, fractures increase the risk factors that contribute to disability and dependency in older adults. Method: A longitudinal case-series study with repeated follow-up assessments was conducted. The sample consisted of 259 older adults. The following tests were administered: Barthel index, Lawton-Brody's scale, Phototest, and informant questionnaire on cognitive decline in the elderly. Results: The main variable which fosters functional dependency, cognitive decline, and functional loss and diminishes functional gain (both in the hospital and at home) is the number of days of bed rest during hospitalization. Conclusions: The present study reveals that the greater impact on levels of functional dependency and cognitive decline comes from the patient's days of bed rest in hospital, rather than the total days of hospitalization. These findings could be taken into consideration when discussing post-discharge functional recovery.
