Cognitive leisure activities and future risk of cognitive impairment and dementia: systematic review and meta-analysis

BACKGROUND: As life expectancies continue to rise, modifiable lifestyle factors that may prevent cognitive decline and dementia in later life become increasingly important in order to maintain quality of life in old age. METHODS: Five meta-analyses were conducted on data from papers identified in a systematic review. Studies were grouped according to outcomes (dementia, cognitive impairment including amnestic Mild Cognitive Impairment (aMCI), Mild Cognitive Impairment (MCI), and cognitive decline) and output (risk (RR), odds (OR), or hazard ratios (HR)). RESULTS: Nineteen studies met our inclusion criteria and quality assessments. Four of five meta-analyses showed significant associations between participation in cognitive leisure activities and reduced risk of cognitive impairment (OR = 0.69, 95% CI: 0.56-0.85) and dementia (HR = 0.58, 95% CI: 0.46-0.74; RR = 0.61, 95% CI: 0.42-0.90; OR = 0.78, 95% CI: 0.67-0.90). However, one pooled analysis of cognitive impairment studies did not reach significance (HR = 0.85, 95% CI: 0.71-1.02). Mentally stimulating leisure activities were significantly associated with later life cognition (β = 0.11, p = 0.05), better memory (β = 0.20, 95% CI: 0.11-0.29), speed of processing (β = 0.37, 95% CI: 0.29-0.45), and executive functioning (β = 0.23, 95% CI: 0.15-0.29), and less decline in overall cognition (β = -0.23, p < 0.01), language (β = -0.11, p < 0.05), and executive functioning (β = -0.13, p < 0.05). Activities were also shown to reduce rate of cognitive decline (estimate = 0.03, SE = 0.01, p = 0.00). CONCLUSIONS: There is increasing evidence that participation in cognitively stimulating leisure activities may contribute to a reduction of risk of dementia and cognitive impairment in later life. Promoting involvement in such activities across lifespan could be an important focus for primary prevention strategies for governments and health services

Service users' involvement in the development of individual Cognitive Stimulation Therapy (iCST) for dementia: a qualitative study

Individual Cognitive Stimulation Therapy (iCST) is a one to one, carer led psychosocial intervention for people with dementia, adapted from group Cognitive Stimulation Therapy (CST). It is increasingly recognised that involving service users in research is key to developing interventions and treatments that successfully address their needs. This study describes the contribution of people with dementia and carers during the development phase of the intervention and materials

Field testing phase of the development of individual Cognitive Stimulation Therapy (iCST) for dementia

Background: Cognitive Stimulation Therapy (CST) groups for people with dementia are available nationally, and internationally through voluntary organisations, memory services, and in residential care settings. However, groups may not be accessible or best suited for all. Individual Cognitive Stimulation Therapy (iCST) has been developed to provide another means of accessing CST. Methods: The programme was field tested by 22 dyads (carers and people with dementia). Dyads were trained in the iCST approach and provided with a manual and accompanying resources. Researchers contacted dyads weekly to provide support and gather adherence data. Quantitative feedback about each session was also collected using ‘Monitoring Progress’ forms. Upon completion of their allocation sessions, researchers interviewed dyads about their experience. In total, nine dyads were followed up. Inductive thematic analysis was performed on the qualitative data. The aims of field testing were to assess the feasibility of the programme, and the appropriateness of the iCST materials. Results: Sixty-two percent of the themes received an overall ‘high’ rating, and the majority of activities were classed as ‘low’ difficulty. Common barriers to completing sessions were; lack of time, illness, and motivation. Carers felt the manual and resources were ‘good’ and easy to use. Benefits of the programme for the person included; improvements in communication, mood, and alertness. The programme also gave carers insight into the person’s abilities and interests, and provided a new channel of communication. Little support was needed to deliver the programme. Conclusions: Implementation of the iCST intervention was feasible. However, the majority of dyads completed fewer than three sessions per week. The training and support package appeared to be suitable as carers were able to deliver the intervention without intensive support. Barriers occurred largely as a result of life commitments, rather than problems with the intervention itself. This study was limited by a high loss to follow up rate. The effectiveness and cost effectiveness of iCST were investigated in a large scale randomised controlled trial (RCT)

The development of individual cognitive stimulation therapy (iCST) for dementia

BACKGROUND: Adopting a systematic approach to the development of an intervention, supported by robust theoretical, empirical, and clinical rationales represents best practice. The Medical Research Council (MRC) provides a framework for a systematic step-wise approach to the evaluation of complex interventions. This study describes the development phase of the individual cognitive stimulation therapy (iCST) for dementia trial, within this framework. METHODS: In the preclinical phase, a recent Cochrane Review of cognitive stimulation for dementia and the current literature on individual cognitive stimulation interventions were examined to establish an evidence base. In addition, people with dementia, carers, and care staff were consulted regarding the acceptability of iCST, and a panel was put together to advise the team on the adaptation of group cognitive stimulation therapy (CST). Phase I (modeling) involved consultations with service users and experts in a series of focus groups, interviews, an online survey, and a consensus conference. Finally, Phase II field testing of the intervention was carried out. RESULTS: Two drafts of the materials were produced before a final version ready for use in the main randomized controlled trial (RCT). Key changes between the drafts included: editorial amendments to improve the clarity of instructions, emphasize the person centeredness of the approach, and reduce the overall length of the introduction section; the simplification of academic terminology and activities deemed "too difficult"; adjustments made to the monitoring-progress forms and session rating scale to enhance user-friendliness; the addition of a "Getting started" section; amendments made to the content of the toolkit; and clearer distinction made between the level of difficulty of activities. CONCLUSION: The rigorous development of the intervention was beneficial as the feasibility of the intervention was explored both in theory and practice, and consulting with service users ensured that materials were appropriately tailored to their needs. A Phase III RCT is currently being conducted to determine the effectiveness of iCST

The failed liberalisation of Algeria and the international context: a legacy of stable authoritarianism

The paper attempts to challenge the somewhat marginal role of international factors in the study of transitions to democracy. Theoretical and practical difficulties in proving causal mechanisms between international variables and domestic outcomes can be overcome by defining the international dimension in terms of Western dominance of world politics and by identifying Western actions towards democratising countries. The paper focuses on the case of Algeria, where international factors are key in explaining the initial process of democratisation and its following demise. In particular, the paper argues that direct Western policies, the pressures of the international system and external shocks influence the internal distribution of power and resources, which underpins the different strategies of all domestic actors. The paper concludes that analysis based purely on domestic factors cannot explain the process of democratisation and that international variables must be taken into more serious account and much more detailed

Down regulation of the high-affinity IgE receptor associated with successful treatment of chronic idiopathic urticaria with omalizumab

Chronic idiopathic urticaria is a condition that is often controllable with antihistamine therapy. However, some patients have disease burden that is difficult to manage, non-responsive to antihistamines and often requires immunosuppressive medications such as corticosteroids or cyclosporine. We present here a study that demonstrates the effectiveness of omalizumab in treating this condition and the temporal relationship between improvement and down regulation of the high affinity IgE receptor (FcεRI). For this, blood samples were obtained from a symptomatic patient before each treatment and processed for flow cytometric analysis of FcεRI levels on the surface of blood basophils. Down regulation of FcεRI was observed in association with significant clinical improvement and discontinuation of immunosuppressive medications

Symptoms and syndromes associated with SARS-CoV-2 infection and severity in pregnant women from two community cohorts

We tested whether pregnant and non-pregnant women differ in COVID-19 symptom profile and severity, and we extended previous investigations on hospitalized pregnant women to those who did not require hospitalization. Two female community-based cohorts (18-44 years) provided longitudinal (smartphone application, N = 1,170,315, n = 79 pregnant tested positive) and cross-sectional (web-based survey, N = 1,344,966, n = 134 pregnant tested positive) data, prospectively collected through self-participatory citizen surveillance in UK, Sweden and USA. Pregnant and non-pregnant were compared for frequencies of events, including SARS-CoV-2 testing, symptoms and hospitalization rates. Multivariable regression was used to investigate symptoms severity and comorbidity effects. Pregnant and non-pregnant women positive for SARS-CoV-2 infection were not different in syndromic severity, except for gastrointestinal symptoms. Pregnant were more likely to have received testing, despite reporting fewer symptoms. Pre-existing lung disease was most closely associated with syndromic severity in pregnant hospitalized. Heart and kidney diseases and diabetes increased risk. The most frequent symptoms among non-hospitalized women were anosmia [63% pregnant, 92% non-pregnant] and headache [72%, 62%]. Cardiopulmonary symptoms, including persistent cough [80%] and chest pain [73%], were more frequent among pregnant who were hospitalized. Consistent with observations in non-pregnant populations, lung disease and diabetes were associated with increased risk of more severe SARS-CoV-2 infection during pregnancy
