Cognitive stimulation program in mild cognitive impairment A randomized controlled trial

Intervention of computer-assisted cognitive training combined with occupational therapy in people with mild cognitive impairment: a randomized controlled trial

Objective

Investigate the impact of combined computerized cognitive training and occupational therapy on individuals with mild cognitive impairment (MCI).

Methods

We randomly assigned 118 MCI patients into two groups: a combined intervention group (n = 37) and a control group (n = 81), the latter receiving standard nursing care. The intervention group additionally underwent 12 weeks of computerized cognitive training and occupational therapy. Blind assessors evaluated cognitive performance, anxiety, depression, and daily living activities before the intervention, post-intervention, and at a 3-month follow-up.

Results

Repeated-measures analysis of variance showed that the sMoCA scores, HAMA scores, and ADL scores of the experimental group at T2 (post-intervention) and T3 (3-month follow-up) were higher than those of the control group, and the difference was statistically significant (p < 0.001, p < 0.001, p = 0.026).

Conclusion

Computerized cognitive training combined with occupational therapy can improve patients' cognitive status, enhance their compliance with continuing care, and maintain their anxiety and self-care ability at a stable level.

Pilot testing cognitive stimulation intervention on older adults' cognitive function, cognitive self-efficacy, and sense of happiness

BACKGROUND

With the ageing population increasing worldwide, identifying effective approaches to counteract cognitive decline becomes significant for maintaining cognitive health and quality of life in older adults. The lack of cognitive activity accelerates age cognitive decline. Cognitive stimulation interventions can maintain older adults' cognitive reserve, enhance their feelings of happiness, and potentially improve their psychosocial wellbeing.

AIM

This study aimed to determine the impact of Cognitive Stimulation Intervention on older adults' cognitive function, cognitive self-efficacy, and sense of happiness.

METHOD

A quasi-experimental methodological approach was applied. Two seniors' clubs were the sites for recruitment in this study as part of the Alexandria Governorate's Ministry of Social Solidarity, Egypt. Eighty older adults (aged 60 and above), randomly assigned into two equal groups. The study group received the study intervention, and the control group received regular seniors' club services.

RESULTS

Cognitive function, cognitive self-efficacy, and sense of happiness scores among the study group, were significantly increased from (22.40 ± 0.67, 54.51 ± 8.63 and 27.68 ± 14.0 respectively) to (24.30 ± 1.07, 87.84 ± 4.96 and 65.98 ± 8.90 respectively) (P < 0.001) following the interventions, and were significantly higher than the control group's post-test percent scores (22.08 ± 0.98, 54.35 ± 6.97, and 28.75 ± 9.60 respectively) (P < 0.001).

CONCLUSIONS

Cognitive Stimulation Intervention effectively fostered the older adults' cognitive function, cognitive self-efficacy, and sense of happiness. Consequently, seniors' clubs, care homes, and other contexts seeking to apply Cognitive Stimulation Intervention to improve older adults' cognitive function, and general wellbeing must embed this intervention as part of their routine care and social activities programs.

Cognitive stimulation and psychosocial results in older adults: A systematic review and meta-analysis

INTRODUCTION

Cognitive stimulation (CS) is a popular and cost-effective intervention, which applies different types of techniques focused on cognitive skills and can be administered by different professionals. CS can be defined as activities that involve cognitive processing usually conducted in a social context and often in a group. Therefore, CS can improve psychosocial functioning and quality of life (QoL), depression, anxiety and activities of daily living (ADLs) independent of the pharmacological treatment such as acetylcholinesterase inhibitors. The objective of this systematic review and meta-analysis was to evaluate the effects of CS on psychosocial outcomes in older adults (aged 65 years or over), with healthy cognitive ageing, mild cognitive impairment (MCI), and dementia.

METHODS

PubMed, Scopus and Web of Science databases were examined from inception to October 2021. A total of 1,997 studies were initially identified in these databases. After discarding studies that did not meet the inclusion criteria, 30 studies were finally included in the systematic review and the meta-analysis performed with robust variance estimator (RVE) due the inclusion of studies with repeated measurements. The quality assessment tools from the National Institutes of Health were used to evaluate the quality of the studies.

RESULTS

CS was significantly associated with a higher QoL in participants who received personalized/adapted CS (RVE = 0.11±0.19 [-0.76, 0.99], t(1.86) = 0.6, p = 0.61). .

CONCLUSION

Personalized/adapted CS seems to improve QoL in older adults.

Is it possible to prevent the progression of mild cognitive impairment through non-pharmacological treatments?

INTRODUCTION

Mild cognitive impairment produces slight cognitive and motor disturbances without affecting daily life during aging, however, if this symptomatology is not controlled, the speed of deterioration can increase, and even some cases of dementia can appear in the elderly population.

OBJECTIVE

To describe non-pharmacological therapies that seek to prevent, control and reduce the symptoms of mild cognitive impairment.

METHODS

An initial search was carried out in the databases of PubMed, Lilacs, EBSCO, ScienceDirect, Taylor & Francis and ProQuest. The results found were filtered through the PRISMA system and biases evaluated using the Cochrane Handbook for Systematic Reviews of Interventions.

RESULTS

Four categories of non-pharmacological therapies were created, using 50 articles found in the search, which contribute to controlling and improving cognitive and motor areas, in order to reduce the symptoms presented by mild cognitive impairment. The treatments have different methods, instruments and objectives, so that no meta-analysis of the studies could be performed. In addition, limitations related to the sample, the effectiveness of the results and the methodological quality were found.

CONCLUSIONS

It was found that non-pharmacological therapies prevent, improve and control the symptoms caused by mild cognitive impairment, however, it is necessary to carry out more studies with better methodologies to corroborate these results.

A systematic review and network meta-analysis comparing various non-pharmacological treatments for older people with mild cognitive impairment

BACKGROUND AND OBJECTIVE

Non-pharmacological therapy appeared to alleviate Mild Cognitive Impairment (MCI) symptoms and signs, according to systematic studies. This network meta-analysis aimed to assess the impact of non-pharmacological therapies on improving cognition in individuals with MCI and identified the most effective intervention.

METHODS

We reviewed six databases in search of potentially relevant studies of non-pharmacological therapies such as Physical exercise (PE), Multidisciplinary intervention (MI), Musical therapy (MT), Cognitive training (CT), Cognitive stimulation (CS), Cognitive rehabilitation (CR)，Art therapy (AT), general psychotherapy or interpersonal therapy (IPT), and Traditional Chinese Medicine (TCM) (such as acupuncture therapy, massage, auricular-plaster and other related systems) and others. Excluded the literature such as missing full text, missing search results, or no reporting specific values and combined with the inclusion criteria and exclusion criteria in this article, the literature ultimately included in the analysis addressed the following seven non-drug therapies PE, MI, MT, CT, CS, CR, AT. Mini-mental state evaluation paired meta-analyses were undertaken by taking weighted average mean differences with confidence intervals (CI) of 95%. The network meta-analysis was conducted to compare various therapies.

RESULTS

A total of 39 randomized controlled trials, including two three-arm studies, with 3157 participants were included. PE was most likely to be the most effective intervention to slow down the cognitive ability of patients (SMD = 1.34, 95%CI: 0.80, 1.89). CS and CR had no significant effect on cognitive ability.

CONCLUSIONS

The non-pharmacological therapy had the potential to greatly promote the cognitive ability of the adult population with MCI. PE had the best chance of being the best non-pharmacological therapy. Due to the limited sample size, substantial variability among different study designs, and the potential for bias, the results should be regarded with caution. Our findings should be confirmed by future multi-center randomized controlled, high-quality large-scale studies.

Cognitive Effects of a Cognitive Stimulation Programme on Trained Domains in Older Adults with Subjective Memory Complaints: Randomised Controlled Trial

Age-related subjective memory complaints (SMC) are a common concern among older adults. However, little is known about the effects of cognitive stimulation (CS) interventions on subjective memory complaints. The aim of this study was to analyse the effectiveness of a CS programme on global cognition and cognitive functions of older adults with SMC. A randomised clinical trial was conducted on older adults with SMC, including 308 participants ≥65 years of age assessed 6 and 12 months after the intervention. The assessment instrument was the Spanish version of the Mini-Mental State Examination (MEC-35), and all domains of the instrument were assessed. For statistical analysis, the data were analysed using robust ANOVA with means truncated at 20% utilising a two-way repeated measures model, with between (groups) and within (measurements) factors. In post hoc tests, a Wilcoxon signed-rank test of exact permutations between groups and Bonferroni correction were applied. In post hoc between-group tests, significant differences were found: (1) post-treatment in MEC-35, temporal orientation, short-term memory (STM), global language and praxis, and language and praxis (p ≤ 0.005); (2) at 6 months in MEC-35, global orientation, temporal orientation, and STM (p = 0.005); (3) at 12 months in MEC-35, global orientation, temporal orientation, STM, global language and praxis, and language (p = 0.005). This study shows benefits in global cognition and orientation, temporal orientation, STM, and language in older adults with SMC.

Cognitive stimulation and cognitive results in older adults: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

The lack of cognitive activity accelerates age cognitive decline. Cognitive stimulation (CS) tries to enhance cognitive functioning. The purpose of this systematic review and meta-analysis was to evaluate the effects of CS on cognitive outcomes (general cognitive functioning and specific cognitive domains) in older adults (aged 65 years or older, cognitively healthy participants, or with mild cognitive impairment, or dementia).

METHODS

PubMed, Scopus and Web of Science databases were examined from inception to October 2021. A total of 1,997 studies were identified in these databases, and. 33 studies were finally included in the systematic review and the meta-analysis. Raw means and standard deviations were used for continuous outcomes. Publication bias was examined by Egger's Regression Test for Funnel Plot Asymmetry and the quality assessment tools from the National Institutes of Health.

RESULTS

CS significantly improves general cognitive functioning (mean difference=MD = 1.536, 95%CI, 0.832 to 2.240), memory (MD = 0.365, 95%CI, 0.300 to 0.430), orientation (MD = 0.428, 95%CI, 0.306 to 0.550), praxis (MD = 0.278, 95%CI, 0.094 to 0.462) and calculation (MD = 0.228, 95%CI, 0.112 to 0.343).

CONCLUSION

CS seems to increase general cognitive functioning, memory, orientation, praxis, and calculation in older adults.

Cognitive Impairment in Older Adults: Epidemiology, Diagnosis, and Treatment

Cognitive impairment and dementia affect dozens of millions of people worldwide and cause significant distress to patients and caregivers and a financial burden to families and health care systems. Careful history-taking, cognitive and physical examination, and supplemental neuroimaging and fluid-based biomarkers can accurately diagnose neurocognitive disorders. Management includes non-pharmacological and pharmacological treatments tailored to the etiology and to the individual.

Effects of a Cognitive Stimulation Program in Institutionalized Patients with Dementia

Background: The advances achieved by the available research that focus on understanding memory operation and cognitive functions have helped the development of specific treatment approaches. These can help to maintain or improve the cognitive function and well-being of people with dementia. The use of cognitive stimulation in dementia has a long history. There are multiple studies that have demonstrated its benefits on the cognitive levels of patients with mild to moderate dementia. However, all of the studies on this type of non-pharmacological intervention conclude that there is a need for more clinical trials in order to give more solidity to the evidence already found. The objective of this pilot study was to assess the effects of an occupational therapy cognitive training program on the cognitive function of institutionalized older adults with dementia. Methods: The study was a pilot randomized clinical controlled trial. A total of 58 participants with major neurocognitive disorder or dementia were randomized to the occupational therapy cognitive training program group or to the conventional occupational therapy group twice a week for 5 weeks. The cognitive level was measured with the Global Deterioration Scale (GDS) and the Lobo’s Cognitive Mini Test (LCMT), which is the Mini-Mental Status Examination in Spanish. Measures were taken at baseline (week 0), after 5 weeks of treatment (week 5), and after 6 weeks of follow up (week 12). A value of p < 0.05 was considered as statistically significant. Results: There were no statistical differences between groups in the LCMT global scores at baseline or after the intervention at week 5. However, the analysis of the specific cognitive areas assessed in the Lobo’s Cognitive Mini Test indicated that that the intervention group significantly improved comprehension of verbal commands and praxis (p = 0.021). At the follow-up measure, the differences obtained in relation to verbal commands and praxis maintained the statistical differences significantly (p = 0.009). Conclusions: Occupational therapy based on cognitive training shows positive effects on the maintenance of the global cognitive state of institutionalized older adults with dementia and improves significantly the comprehension of verbal commands and praxis.

Cognitive Stimulation as Alternative Treatment to Improve Psychological Disorders in Patients with Mild Cognitive Impairment

(1) Background: Mild cognitive impairment is becoming one of the most common clinical manifestations affecting older people. For this reason, developing non-pharmacological strategies to help improve or maintain the physical condition of patients with mild dementia has become a priority. Therefore, the objective of this study is to provide evidence about the effects of a cognitive stimulation program on cognitive performance, anxiety, depression, and quality of life in people with mild cognitive impairment (MCI) and aged > 70. (2) Methods: This study is a randomized clinical trial. A total of 72 elderly people with MCI participated: 35 in the control group who did not receive any intervention and 36 in the experimental group who received a cognitive stimulation program for 12 weeks. Cognitive performance, depression, anxiety and health-related quality of life (HRQoL) were measured using the Mini-Mental State Examination (MMSE), the Yesavage Geriatric Depression Scale, the Hamilton Rating Scale, and the SF-12, respectively. (3) Results: In the experimental group, significant results were obtained on cognitive performance, depression, anxiety and general health, emotional role, social functioning, vitality, mental health and mental component summary domains of the SF-12. (4) Conclusions: a cognitive stimulation program of 12 weeks improves cognitive performance, anxiety, depression, and HRQoL in people with MCI aged > 70.

Effectiveness of Personalized Cognitive Stimulation in Older Adults with Mild Possible Cognitive Impairment: A 12-month Follow-up Cognitive Stimulation in Mild Cognitive Impairment

OBJECTIVE

The objective of this study was to analyze the long-term effects of a personalized cognitive stimulation (PCS) program on the global cognition, cognitive aspects, activities of daily living (ADLs), anxiety, and depression in older adults with possible mild cognitive impairment (MCI).

METHODS

A 12-month follow-up analysis was carried out in a single-blind, randomized clinical trial to research the long-term effects of a 10-week PCS program evaluating the cognitive level, depression, and anxiety of older adults with possible MCI.

RESULTS

Fifty older adults were assessed 12 months after the CS program, 23 in the intervention group and 27 in the control group. There were significant differences between the groups at 12 months in the global cognition (p = .002), in global orientation (p < .001), and in spatial orientation (p = .004) in favor of the intervention group, measured with the Spanish version of the Mini-Mental Status Examination (MEC-35).

CONCLUSIONS

A PCS program could be effective in improving global cognition and global and spatial orientation.

CLINICAL IMPLICATIONS

A PCS program based on cognitive levels in older adults with possible MCI achieves improvements in global cognition and global and spatial orientation. PCS programs can be applied successfully by trained occupational therapists.

Non-pharmacological Approaches to Apathy and Depression: A Scoping Review of Mild Cognitive Impairment and Dementia

Apathy and depression are frequently observed as behavioral and psychological symptoms of dementia, respectively, and are important for ensuring adequate care. This study aims to explore effective non-pharmacological interventions for apathy and depression with mild cognitive impairment (MCI) and dementia. Five search engines including PubMed, Scopus, CINAHL, PsycInfo, and Web of Science were used to extract relevant studies. Inclusion criteria were studies that involved participants who were diagnosed with MCI or dementia, included quantitative assessments of each symptom, and employed randomized controlled trials. Twenty studies were extracted, with interventions have been conducted in care facilities, the community, and hospitals. Participants in many studies had MCI or mild-to-moderate dementia but were not diagnosed with the subtypes of dementia. Few studies had set apathy and depression as the primary outcomes of non-pharmacological interventions. The findings suggested that emotional and stimulation-oriented approaches to apathy and depression would be useful for people with MCI or mild-to-moderate dementia. It would be helpful for therapists to assess the clinical features of the target symptoms for selecting suitable interventions. Additionally, increasing the number of randomized controlled trials focusing on apathy or depression as primary outcomes would offer a more definite conclusion for future systematic reviews.

[Long-term effect analysis of a cognitive stimulation program in mild cognitive impairment elderly in Primary Care: A randomized controlled trial]

OBJECTIVE

To provide evidence about the efficacy of a community health intervention through a cognitive stimulation program at long term in older people with mild cognitive impairment.

DESIGN

Randomized controlled trial (CONSORT group norms).

LOCATION

San José Norte-Centro Primary Care Center and La Caridad Foundation (Zaragoza, Spain).

PARTICIPANTS

Twenty-nine people over 65 years old with a 24-27 MEC score that completed 48 months follow up. They were randomized between the intervention group (15) and the control group (14).

INTERVENTIONS

The intervention was applied in 10 sessions of 45min for 10 weeks using the red notebook tool for mental activation that works memory, orientation, language, praxis, gnosis, calculation, perception, logical reasoning, attention and executive functions.

MAIN MEASUREMENTS

The main outcome variables were MEC-35, Set-test, Barthel index, Lawton-Brody scale, Goldberg anxiety scale and Yesavage geriatric depression scale short form.

RESULTS

Increases of the main result variable over the baseline level of MEC-35 were analyzed. On average, the intervention group obtained higher scores than control: 3.14 points post intervention, 3.76 points after 6 months and 2.26 points more than control group after 12 months. All the differences were statistically significant. After 48 months the intervention group obtained 2 points more than control group. The intervention did not improve verbal fluency, activity daily living and mood.

CONCLUSIONS

Our cognitive stimulation program seems to improve cognitive performance, measured with the variable MEC-35 at post intervention, 6, 12 and 48 months. There is no evidence of improvement in verbal fluency, activity daily livings and mood. Clinicaltrials.gov Identifier: NCT03831061.

Home/community-based interventions to improve function in persons with mild cognitive impairment/early dementia

Persons with mild cognitive impairment/early dementia have a possible 20-year trajectory of disability and dependence with little information on the effectiveness of interventions to improve function. This review investigates the literature of home/community-based interventions for physical and executive function in persons with mild cognitive impairment/early dementia. A 2007-2020 systematic literature search was conducted through PubMed, CINAHL Plus with Full Text and PsycINFO. Of the 1749 articles retrieved, 18 eligible studies were identified and consisted of three types of interventions: cognitive training-only (n = 7), multicomponent (n = 9), and physical activity-only (n = 2). Results showed that the interventions impacting function in persons with cognitive impairment incorporated a visual/written element, technology-based training, caregiver support, and modified duration/increased frequency of interventions. In studies improving function, participants simulated Instrumental Activities of Daily Living. They addressed cognitive function using both objective and subjective cognitive measures. We found gaps in the literature in incorporating race/ethnicity and appropriate socioeconomic status measures.

Effects of a Cognitive Rehabilitation Programme on the Independence Performing Activities of Daily Living of Persons with Dementia-A Pilot Randomized Controlled Trial

Background: In all types of dementia, cognitive abilities are affected, behaviour is altered and functional capacity is progressively lost. This cognitive deterioration manifests in the decrease of abilities required to perform the activities of daily living (ADL). The objective of this pilot study was to assess the effect of an Occupational Therapy programme based on the training of ADL through cognitive stimulation on the independence of ADL of persons with dementia. Methods: Institutionalized older adults with major neurocognitive disorder or dementia (N = 58) were randomly allocated to receive either the Occupational Therapy ADL cognitive stimulation programme or conventional Occupational Therapy. The cognitive level and the independence level performing ADL were measured at baseline (week 0), after 5 weeks of treatment (week 5) and after 6 weeks of follow up (week 12). A value of p < 0.05 and α = 0.0025 (Bonferroni correction) was considered as statistically significant. Results: The results obtained showed improvements in the level of independence performing ADLs in the intervention group compared to the control group (p = 0.006). The improvements were seen in relation to feeding (p = 0.001), dressing (p = 0.005) and bladder and bowel incontinence (p = 0.003), the changes observed in feeding are statistically significant. However, those improvements were not maintained after the follow up period. There were no significant changes in relation to the cognitive level (p = 0.741). Conclusions: Occupational Therapy based on ADL cognitive stimulation can have a positive effect, increasing the independence of subjects with major neurocognitive disorder or dementia who are institutionalised.
