Factors associated with the occupational balance in caregivers of people with dementia: A cross-sectional study from the ATENEA project

BACKGROUND

Occupational balance (OB) has been associated with health indicators in informal caregivers (CGs) such as well-being and subjective health. Consequently, maintaining an adequate OB could be crucial to providing adequate care without becoming overwhelmed, converting the condition of caregivers into an important aspect of public health as the ageing population increases. However, little is known about the factors influencing OB in CGs. Thus, this study aimed to explore the associated factors with the OB in CGs of persons with dementia.

METHODS

We cross-sectionally analysed data from 134 CGs and the individuals with dementia. We assessed CGs' OB using the Occupational Balance Questionnaire (OBQ). Simultaneously, several sociodemographic, clinical, and caregiving-related variables including CGs' burden and psychological distress were assessed. The association between the CGs' OB and those factors was explored through robust multiple linear regression.

RESULTS

Firstly, CGs that presented secondary education exhibited a decrement of 5.41 (CI95% = -10.62, -0.41; p-value = 0.03) OB points. Moreover, CGs with higher education experienced a more pronounced OB reduction (β = -7.74; 95%CI = -12.19, -3.29; p-value = < 0.001). Secondly, those CGs that were retired showed an OB increment of 5.52 (CI95% = 1.14, 9.38; p-value = 0.01). Thirdly, receiving assistance with household chores was associated with an OB increase of 5.80 (CI95% = 2.21, 9.38; p-value = 0.001). Fourthly, and regarding clinical measures, CGs experiencing overload or psychological distress were associated with an OB points decrement of 7.87 (CI95% = -12.51, -3.23; p-value = 0.001) and 9.17 (CI95% =-13.51, -4.84; p-value < 0.001), respectively. Finally, 1% increment in the Disability Assessment for Dementia obtained from the individuals with dementia was associated with an increment of 0.11 (CI95% = 0.04, 0.18; p-value = 0.002) OB points.

CONCLUSIONS

This study identified several associated factors with the OB of CGs of persons with dementia. Specifically, we remarked that the CGs' education, employment status, household chores assistance, overload presence, psychological distress symptoms and the functional level of the person with dementia who cared for were important variables that should be considered when evaluating OB or creating OB-related interventions in CGs.

Validation of the Attitudes toward Lying to People with Dementia (ALPD) Questionnaire among Social Workers in Spain

Gerontological interventions should address the various geriatric syndromes suffered by the elderly, such as neurodegenerative diseases. Therapeutic lying is an effective and humanizing strategy to deal with dementia, used by various disciplines in the social and healthcare fields. This intervention strategy is made up of all the different responses to reality that are given to a person with cognitive impairment. This study analyzes the validity of the Spanish adaptation of the Attitudes toward Lying to People with Dementia (ALPD) questionnaire, given to 253 social workers who directly and indirectly intervened with older people suffering from cognitive impairment in public and private centers in Spain during the year 2022. The results of the validity and reliability analyses support the psychometric quality of ALPD for use in Spanish social workers. The statistical results indicate a good fit of the bifactor model (person-focused and lie-focused) and show the questionnaire to be reliable, with adequate psychometric properties. The article concludes with a discussion of practical, formative, and ethical challenges for social work in the field of geriatric services.

Interventions to Relieve the Burden on Informal Caregivers of Older People with Dementia: A Scoping Review

Dementia increases dependence in older adults and decreases their quality of life and that of their family members. These family members often take on the responsibility of caregiving and suffer from burden and health deterioration due to facing various stressors. The aim is to verify the effectiveness of existing interventions aimed at relieving the burden and stress of informal caregivers of older people with dementia. A scoping review was conducted by consulting the Web of Science, Scopus, ProQuest, and PubMed databases, following the guidelines of the PRISMA 2020 Statement. The review protocol has been registered in PROSPERO under number CRD42024558609. Twenty-six articles met the inclusion criteria and were reviewed, studying the type of intervention design, the sample size of caregivers and their main characteristics, the duration and follow-up, and the variables investigated with their respective measurement instruments. The analysis of the different studies showed that the most developed types of interventions are psychoeducational and cognitive-behavioral therapies, both individual and group. These interventions were mainly effective in reducing the burden and depressive symptoms of caregivers. It is considered advisable to implement more randomized controlled trials for further research, because as the number of caregivers increases, so does the need for affordable and effective interventions.

Effectiveness of psychological interventions for reducing depressive symptomatology and overload and improving quality of life in informal caregivers of non-institutionalized dependent elderly: a systematic review

Introduction

The phenomenon of aging is distinguished by profound life transformations, with the most dependent group being constituted by elderly individuals. The responsibility for their care primarily falls on the figure of the informal caregiver. The scarcity of time, the stress associated with caregiving, the financial, work-related, and personal difficulties it entails, make it a collective with high probabilities of experiencing various psychological disorders. Interventions that have shown the best results are those of multiple components, composed of various techniques that seek to adapt to the reality of the informal caregiver.

Method

The purpose of this study is a systematic review of effective interventions on depressive symptoms, emotional wellbeing, burden, or quality of life in informal caregivers of non-institutionalized dependents from 2018 to the present. A search was conducted in November 2023, on Pubmed, Pubmed Central, Proquest, and Scielo. The final review was conducted on 11 articles.

Results

The results indicate that multiple component interventions including cognitive behavioral techniques and psychoeducation in combination with stress coping techniques and social support are more effective on depressive symptoms, burden, quality of life, and increasing the social support network.

Discussion

Results on web-based programs demonstrate their efficacy and effectiveness, but require a greater number of trials to adjust their methodological quality and content to the idiosyncrasies of the informal caregiver.

Risk of dementia among antidepressant elderly users: A population-based cohort analysis in Spain

The use of antidepressants with anticholinergic effects has been associated with an increased risk of dementia. However, the results published are contradictory. The aim of the study is to compare the risk of developing dementia in elderly who were prescribed tricyclic antidepressants (TCA) versus those who were prescribed selective serotonin reuptake inhibitors (SSRIs) and other antidepressants (OA). A prospective population-based cohort study was performed using the Spanish Database for Pharmacoepidemiological Research in Primary Care (BIFAP) data (from 2005 to 2018). The cohort study included 62,928 patients age ≥ 60 without dementia and with antidepressant long-term monotherapy. Patients were divided into exposure antidepressant groups based on ATC system [TCA, SSRIs users and OAs users]. The risk of dementia was calculated by Cox regression models, providing hazard ratios (HR) and 95 % confidence intervals. The Kaplan-Meier model was used for survival analysis. Chi2 test was used as association test. The results showed SSRI users had higher dementia risk than TCA users (HR = 1.864; 95%CI = 1.624-2.140). Moreover, OA users had also significant risk of dementia (HR = 2.103; 95%CI = 1.818-2.431). Several limitations are the variation of the trend in the prescription of antidepressants, the small number of patients that use some antidepressants, the lack of information related to the dose, or socioeconomic characteristics, the use of antidepressant drugs for other indications, or the therapeutic compliance. Our findings showed that older users of SSRI and OA have more risk of developing dementia than TCA elderly users. However, additional studies would be needed.

Discovery of novel multifunctional ligands targeting GABA transporters, butyrylcholinesterase, β-secretase, and amyloid β aggregation as potential treatment of Alzheimer's disease

Alzheimer's disease (AD) is a global health problem in the medical sector that will increase over time. The limited treatment of AD leads to the search for a new clinical candidate. Considering the multifactorial nature of AD, a strategy targeting number of regulatory proteins involved in the development of the disease is an effective approach. Here, we present a discovery of new multi-target-directed ligands (MTDLs), purposely designed as GABA transporter (GAT) inhibitors, that successfully provide the inhibitory activity against butyrylcholinesterase (BuChE), β-secretase (BACE1), amyloid β aggregation and calcium channel blockade activity. The selected GAT inhibitors, 19c and 22a - N-benzylamide derivatives of 4-aminobutyric acid, displayed the most prominent multifunctional profile. Compound 19c (mGAT1 IC50 = 10 μM, mGAT4 IC50 = 12 μM and BuChE IC50 = 559 nM) possessed the highest hBACE1 and Aβ40 aggregation inhibitory activity (IC50 = 1.57 μM and 99 % at 10 μM, respectively). Additionally, it showed a decrease in both the elongation and nucleation constants of the amyloid aggregation process. In contrast compound 22a represented the highest activity and a mixed-type of eqBuChE inhibition (IC50 = 173 nM) with hBACE1 (IC50 = 9.42 μM), Aβ aggregation (79 % at 10 μM) and mGATs (mGAT1 IC50 = 30 μM, mGAT4 IC50 = 25 μM) inhibitory activity. Performed molecular docking studies described the mode of interactions with GATs and enzymatic targets. In ADMET in vitro studies both compounds showed acceptable metabolic stability and low neurotoxicity. Successfully, compounds 19c and 22a at the dose of 30 mg/kg possessed statistically significant antiamnesic properties in a mouse model of amnesia caused by scopolamine and assessed in the novel object recognition (NOR) task or the passive avoidance (PA) task.

Impact of discontinuing non-pharmacological interventions on cognitive impairment in dementia patients by COVID-19 lockdown. A pilot observational, longitudinal, retrospective study carried out in an adult day center in Spain during the COVID-19 pandemic

Background

The lockdown imposed during the COVID-19 pandemic led to social isolation and prevented patients with dementia from receiving a suite of non-pharmacological interventions (NPIs) that prevent cognitive decline. This discontinuation of NPIs could substantially affect the mental health status of people with dementia in social care settings, such as adult day care centers (ADCs).

Propose

The study aimed to evaluate the effects of the COVID-19 lockdown on mental health and cognitive impairment in patients with dementia who could not attend their usual ADCs and did not receive our NPIs, based on World Health Organization (WHO) Guidelines.

Methods

Observational, longitudinal, retrospective study carried out in an adult day center in Spain and reported it in accordance with the Strengthening Reporting of Observational Studies in Epidemiology (STROBE) statement. Cognitive status was assessed using the Mini-Mental State Examination (MMSE) in 80 patients attending the ADC of the "Leonese Association of Dementia Patients" (León, Spain), who had been evaluated with this instrument before the COVID-19 lockdown.

Results

We observed a 0.4-point decrease in MMSE score/month (IQR = 1.4) during lockdown versus a 0.1-point decrease/month (IQR = 0.3) before this period (p = 0.038). Notably, this translated to >10-point decreases in MMSE score/year in 33.8% of participants during lockdown versus 5.5% earlier (p < 0.001). No statistically significant associations (p < 0.05) were found between the individual characteristics of the caregivers and the occurrence of the event.

Conclusion

The reported declines in MMSE scores reveal a significant acceleration of cognitive decline during the period of inactivity. This could suggest that our NPIs, focused on slowing cognitive decline, are beneficial and, therefore, necessary in patients with dementia.

Intranasal Drug Administration in Alzheimer-Type Dementia: Towards Clinical Applications

Alzheimer-type dementia (ATD) treatments face limitations in crossing the blood-brain barrier and systemic adverse effects. Intranasal administration offers a direct route to the brain via the nasal cavity's olfactory and trigeminal pathways. However, nasal physiology can hinder drug absorption and limit bioavailability. Therefore, the physicochemical characteristics of formulations must be optimized by means of technological strategies. Among the strategies that have been explored, lipid-based nanosystems, particularly nanostructured lipid carriers, are promising in preclinical investigations with minimal toxicity and therapeutic efficacy due to their ability to overcome challenges associated with other nanocarriers. We review the studies of nanostructured lipid carriers for intranasal administration in the treatment of ATD. Currently, no drugs for intranasal administration in ATD have marketing approval, with only three candidates, insulin, rivastigmine and APH-1105, being clinically investigated. Further studies with different candidates will eventually confirm the potential of the intranasal route of administration in the treatment of ATD.

Cost-Effectiveness of the Comprehensive Interdisciplinary Program-Care in Informal Caregivers of People with Alzheimer's Disease

People with Alzheimer's disease (AD) diagnosis who get informal care remain at home longer, reducing the demand for healthcare resources but increasing the stress of caregiving. Research on the effectiveness of physical training, psychoeducational, cognitive-behavioural, and health education programs in reducing the caregiver load and enhancing health-related quality of life (HRQoL) exist, but none exist about an integrated interdisciplinary program. The goals of this project are (1) to assess the Integral-CARE Interdisciplinary Program (IP) applicability, safety, effects on HRQoL, and the incremental cost-effectiveness ratio for AD caregivers; (2) to evaluate the IP applicability and cost-effectiveness to enhance the physical, psychoemotional, cognitive-behavioural dimensions, and the health education status of informal caregivers, and (3) to study the transference of the results to the public and private sectors. A randomized controlled trial will be conducted with an experimental (IP) and a control group (no intervention). The PI will be conducted over nine months using face-to-face sessions (twice a week) and virtual sessions on an online platform (once a week). There will be an initial, interim (every three months), and final assessment. Focus groups with social and health agents will be organized to determine the most important information to convey to the public and private sectors in Extremadura (Spain). Applicability, safety, HRQoL, incremental cost-effectiveness ratio, and HRQoL will be the main outcome measures, while secondary measures will include sociodemographic data; physical, psychoemotional, health education, and cognitive-behavioural domains; program adherence; and patient health status. Data will be examined per procedure and intention to treat. A cost-effectiveness study will also be performed from the viewpoints of private and public healthcare resources.

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.

Factores que influyen en la sobrecarga de cuidadores informales de pacientes con Trastorno Neurocognitivo debido a enfermedad de Alzheimer

La sobrecarga es uno de los fenómenos presentados en los cuidadores de pacientes con Alzheimer. El objetivo de esta investigación fue identificar los factores que influyen en la sobrecarga de cuidadores informales de pacientes con Alzheimer, partícipes de un programa de intervención en Bucaramanga, Santander, Colombia. El estudio fue transversal anidado en un ensayo controlado aleatorizado con 3 grupos en paralelo, y con una muestra a conveniencia de 58 cuidadores. Adicionalmente, se aplicó la escala de carga del cuidador de Zarit y una entrevista estructurada, al igual que se utilizó un modelo de efectos mixtos con varianza no estructurada. Se encontró que la edad media fue de 55.6 años (79.3 %), mujeres e hijos (70.7 %), un bajo uso de redes de apoyo (8.6 %) y una mediana de dedicación al cuidado de 24 horas/día. Como factores asociados a la sobrecarga, por cada año del cuidador, la sobrecarga disminuye 0.5 puntos (p = 0.005), así como se encuentra con más sobrecarga a los cuidadores cuyos pacientes tienen una mayor afectación del comportamiento (p = 0.003), los cuidadores que tienen otro empleo (p = 0.025) y la falta de apoyo brindado por otros familiares (p = 0.014). Estos resultados permiten caracterizar a familiares cuidadores en quienes se requiere una intervención multidisciplinaria.

Validation of the Chinese version of the Family Crisis Oriented Personal Evaluation Scales in families of patients with dementia

Caring for people with dementia causes heavy care burdens to their families. Family coping is important in decreasing burdens and promoting family adaptation. To comprehensively assess and understand these issues, we validated the Chinese version of the Family Crisis Oriented Personal Evaluation Scales (F-COPES) which is widely used to evaluate family coping. Data for psychometric property evaluation were obtained from 215 family members of patients with dementia. The instrument showed satisfactory content validity (scale content validity index 0.98), convergent validity (r = 0.50, P < 0.01), and internal consistency (Cronbach's alpha 0.86). The confirmatory factor analysis identified six factors, namely, acquiring relatives' support, acquiring friends' support, acquiring neighbors' or others' support, seeking spiritual support, reframing, and passive appraisal (χ²/df 1.86, CFI 0.88, TLI 0.87, PGFI 0.68, RMSEA 0.06). This instrument may serve as a useful scale for assessing the coping behaviors of families of patients with dementia in mainland China.

Impact of Educational Level on Versions (Basic and Complete) of the Montreal Cognitive Assessment

BACKGROUND

One of the most marked problems in the use of screening instruments for the diagnosis of dementia or cognitive impairment in the elderly is the influence of educational level on the results of psychometric tests. The Montreal Cognitive Assessment (MoCA) questionnaire is one of the most widely used dementia screening instruments internationally and with greater proven validity. There is a version of this instrument called MoCA "Basic" which was developed to reduce education bias. The aim of the study was to compare the psychometric characteristics of the MoCA, full versus basic, versions in older adults.

METHOD

Participants (N = 214) completed both versions of the MoCA, and screening measures to corroborate their health status.

RESULTS

Internal consistency was satisfactory in both versions: MoCA full (0.79) and MoCA basic (0.76). The overall correlation between both tests was high (0.73). There was no relationship between the dimensions included in each version. Educational level and age explained 33.8% of the total variance in MoCA Full and 31.8% in MoCA Basic. Among educational levels, there are statistically significant differences in participants with <6 years of education.

CONCLUSIONS

The results confirm that both versions are reliable instruments and also show that in both versions the educational level of <6 years of education continues to have an impact on performance. Therefore, it can be considered that the MoCA Basic version for the Ecuadorian population with <6 years of education continues to imply literacy competencies.

Regression-Based Normative Data for Independent and Cognitively Active Spanish Older Adults: Free and Cued Selective Reminding Test, Rey-Osterrieth Complex Figure Test and Judgement of Line Orientation

The aim of this work was to develop normative data for neuropsychological tests for the assessment of independent and cognitively active Spanish older adults over 55 years of age.

METHODS

regression-based normative data were calculated from a sample of 103 nondepressed independent community-dwelling adults aged 55 or older (66% women). The raw data for the Free and Cued Selective Reminding Test (FCSRT), the Rey-Osterrieth Complex Figure Test (ROCF) and the Judgement of Line Orientation Test (JLO) were regressed on age, sex and education. The model predicting the FCSRT delayed-recall (FCSRT-Del) scores also included the FCSRT immediate-recall (FCSRT-Imm) scores. The model predicting the ROCF immediate-recall (ROCF-Imm) scores included the ROCF copy-trial (ROCF-C) scores, and the model predicting the ROCF delayed-recall (ROCF-Del) scores included both the ROCF-C and the ROCF-Imm scores. In order to identify low scores, z-scores were used to determine the discrepancy between the observed and the predicted scores. The base rates of the low scores for both the SABIEX normative data and the published normative data obtained from the general population were compared.

RESULTS

the effects of the different sociodemographic variables (age, sex and education) varied throughout the neuropsychological measures. Despite finding similar proportions of low scores between the normative data sets, the agreement was irrelevant or only fair-to-good.

CONCLUSIONS

the normative data obtained from the general population might not be sensitive enough to identify low scores in cognitively active older adults, incorrectly classifying them as cognitively normal compared to the less active population.

Resilience, Emotional Intelligence, and Occupational Performance in Family Members Who Are the Caretakers of Patients with Dementia in Spain: A Cross-Sectional, Analytical, and Descriptive Study

Background: The concern in the scientific community for the study of people with dementia and their families is comprehensible, especially the importance of knowing the effects that caring for the patient has on their family dynamic, paying special attention to the main caregiver. The objective of this study was to analyze the relationship of resilience and emotional intelligence with functional performance in the main caregivers of people with dementia in Spain according to the phase of the disease. Methods: A cross-sectional, descriptive, and analytical study was carried out. A total of 144 primary family caregivers of patients with dementia in Spain were included in the study. The following variables were measured: sociodemographic, psychosocial, and occupational, as well as resilience and emotional intelligence. Results: The caregivers obtained a low moderate resilience (mean = 64.01 ± 14.5), an emotional intelligence bordering between moderate and high (mean = 78.48 ± 14.82), and a 61.8% self-care categorized as somewhat and quite a bit. The presence of higher levels of resilience in family caregivers of people with dementia were positively related to the time spent on self-care (r = 0.227; p = 0.033) and leisure (r = 0.262; p = 0.014), especially in the moderate phase of the disease, while in the severe phase, this relationship appeared with productivity (r = 0.355; p = 0.034). The higher levels of emotional intelligence were positively related to a greater time dedicated to self-care (r = 0.233, p = 0.005), as well as the data observed in the moderate and severe phase (r = 0.214; p = 0.046 and r = 0.398; p = 0.016 respectively). Conclusions: The primary caregivers of relatives with dementia who have higher levels of resilience and emotional intelligence spend more time on self-care and leisure activities, especially in the moderate phase of the disease.

Effectiveness of technology-based interventions in detection, prevention, monitoring and treatment of patients at risk or diagnosed with mild cognitive impairment: protocol for a systematic review

INTRODUCTION

The gradual changes over the decades in the longevity and ageing of European society as a whole can be directly related to the prolonged decline in the birth rate and increase in the life expectancy. According to the WHO, there is an increased risk of dementia or other cognitive disorders as the population ages, which have a major impact on public health. Mild cognitive impairment (MCI) is described as a greater than expected cognitive decline for an individual's age and level of education, but that does not significantly interfere with activities of daily living. Patients with MCI exhibit a higher risk of dementia compared with others in the same age group, but without a cognitive decline, have impaired walking and a 50% greater risk of falling.The urban lifestyle and advent of smartphones, mobility and immediate access to all information via the internet, including health information, has led to a totally disruptive change in most general aspects.This systematic review protocol is aimed at evaluating the effectiveness of technology-based interventions in the detection, prevention, monitoring and treatment of patients at risk or diagnosed with MCI.

METHODS AND ANALYSIS

This review protocol follows the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols reporting guidelines. The search will be performed on MEDLINE (PubMed), CENTRAL, CINAHL Plus, ISI Web of Science and Scopus databases from 2010 to 2020. Studies of interventions either randomised clinical trials or pre-post non-randomised quasi-experimental designs, published in English and Spanish will be included. Articles that provide relevant information on the use of technology and its effectiveness in interventions that assess improvements in early detection, prevention, follow-up and treatment of the patients at risk or diagnosed with MCI will be included.

ETHICS AND DISSEMINATION

Ethics committee approval not required. The results will be disseminated in publications and congresses.

Therapeutic potential of nanoemulsions as feasible wagons for targeting Alzheimer's disease

Alzheimer's disease (AD) is an irreversible dementia state with characteristic clinical manifestations, including declining cognitive skills and loss of memory, which particularly affects the older population. Despite significant efforts in the field of nano-based drug delivery, there have been few successes achieved in the design of a rational drug therapy. Nanoemulsions (NEs) have potential for the delivery of AD therapeutics owing to their capability for brain drug delivery. Still, there is a long way to go before such therapeutics become a reality in the clinic. In this review, we highlight the preclinical assessment of NEs for AD and discuss the regulatory constraints to their clinical acceptance.

Pharmacist-Physician Interprofessional Collaboration to Promote Early Detection of Cognitive Impairment: Increasing Diagnosis Rate

The increased pressure on primary care makes it important for other health care providers, such as community pharmacists, to collaborate with general practitioners in activities related to chronic disease care. Therefore, the objective of the present project was to develop a protocol of action that allows close pharmacist-physician collaboration to carry out a coordinated action for very early detection of cognitive impairment (CI). Methods: A comparative study to promote early detection of CI was conducted in 19 community pharmacies divided into two groups: one group with interprofessional collaboration (IPC) and one group without interprofessional collaboration (NonIPC). IPC was defined as an interactive procedure involving all pharmacists, general practitioners and neurologists. A total of 281 subjects with subjective memory complaints were recruited. Three tests were used in the community pharmacies to detect possible CI: Memory Impairment Screening, Short Portable Mental State Questionnaire, and Semantic Verbal Fluency. Individuals with at least one positive cognitive test compatible with CI, were referred to primary care, and when appropriate, to the neurology service. Finally, we evaluated the differences in clinical and diagnostic follow-up in both groups after six months. Results: The NonIPC study group included 38 subjects compatible with CI referred to primary care (27.54%). Ten were further referred to a neurology department (7.25%) and four of them (2.90%) obtained a confirmed clinical diagnosis of CI. In contrast, in the IPC group, 46 subjects (32.17%) showed results compatible with CI and were referred to primary care. Of these, 21 (14.68%) were subsequently referred to a neurology service, while the remaining 25 were followed up by primary care. Nineteen individuals out of those referred to a neurology service obtained a confirmed clinical diagnosis of CI (13.29%). The percentage of subjects in the NonIPC group referred to neurology and the percentage of subjects diagnosed with CI, was significantly lower in comparison to the IPC group (p-value = 0.0233; p-value = 0.0007, respectively). Conclusions: The creation of IPC teams involving community pharmacists, general practitioners, and neurologists allow for increased detection of patients with CI or undiagnosed dementia and facilitates their clinical follow-up. This opens the possibility of diagnosis in patients in the very early stages of dementia, which can have positive implications to improve the prognosis and delay the evolution of the disease.

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.

Intervention Program to Improve Grief-Related Symptoms in Caregivers of Patients Diagnosed With Dementia

The objectives of the present study were to adapt a grief intervention program to family caregivers of patients with dementia, and assess its effectiveness in improving the symptoms of grief and other health-related variables. The intervention was based on Shear and Bloom's grief intervention program, with the necessary adaptations for use in the grieving process for a family member's illness. A total of 52 family caregivers of individuals with dementia participated. They were evaluated using a battery of self-report measures assessing grief, overload, resilience, post-traumatic growth, experiential avoidance, health-related quality of life, and benefits of care. The results suggest that the program is effective in improving grief symptoms, caregiver burden, resilience, post-traumatic growth, and quality of life of family caregivers. It is necessary to create and implement interventions targeting caregivers' feelings and manifestations of ambiguous grief, because there is a lack of programs providing an efficient solution for the mental and physical health of caregivers, and because of the human and socioeconomic cost involved in neglecting this group.

Computerized cognitive stimulation for people with dementia or with mild cognitive impairment: a bibliometric review

Many studies have found that non-pharmacological interventions, such as cognitive stimulation (CS), can benefit people with dementia (PWD) or with mild cognitive impairment (MCI). The use of the computerized cognitive stimulation (CCS) had proven to be an ally to those who want to detect and mitigate this disease.

OBJECTIVE

The purpose of this paper was to analyze the scientific production in CCS in PWD or with MCI in journals indexed in Clarivate Analytics' Web of Science and Elsevier's Scopus since 2000.

METHODS

Data collected from Web of Science and Scopus during 2000-2019.

RESULTS

The data show that dementia research is exponentially developing following the evolution of widespread use of computer science. As such, this article was of enormous importance doing a bibliometric analysis of what has been done in the area since the beginning of this century. The search terms identified 61 papers related to the use of computers applied to CS in PWD or MCI, and the International Journal of Geriatric Psychiatry and Journal of Alzheimer's Disease had the largest number of publications. The most cited article was the Faucounau et colleagues. Major research' countries are United Kingdom, Spain and United States.

CONCLUSIONS

The findings in these papers were analysed to find recommendations for future work in this area. The CCS has been increasingly used as an intervention tool for PWD or MCI, and there still seems to be a possibility for evolution in good quality publications.

Caring for Family Members With Alzheimer's and Burnout Syndrome: Impairment of the Health of Housewives

Being a housewife may already be a psychosocial risk factor leading to chronic stress and burnout, and this may be aggravated when the housewife must also become the caregiver of a family member with Alzheimer’s. The burnout syndrome and how it can affect general health and the presence of emotional disorders were studied in housewives who were family caregivers of an Alzheimer’s patient. The sample selected was made up of 193 housewives, 96 of whom were also caregivers for a family member with Alzheimer’s. Sociodemographic measures used were the Maslach Burnout Inventory and The General Health Questionnaire. Burnout was found in a significant percentage of participants. Emotional exhaustion, effect on general health, and presence of emotional disorders were higher in caregivers. Emotional exhaustion, general health, and anxiety were more influential, while depersonalization affected the appearance of depressive symptoms more. Being a caregiver and emotional exhaustion appeared to be the best predictors of emotional disorders. It was confirmed that emotional exhaustion influenced appearance of anxiety and depression equally in both groups. In the case of caregivers, an exhaustion-illness spiral was produced. In this group, emotional exhaustion seemed to become more severe as a consequence of the presence of chronic illnesses, and possibly influence the number of hours spent on care and having children living at home. Future research should analyze in greater depth and in a larger sample, the role of these variables and widen the focus of attention to personal variables that could be acting as protective factors and could be subject to intervention. The discussion concludes with some actions that should be included in prevention programs for the groups studied.

The impact of dementia on hospital outcomes for elderly patients with sepsis: A population-based study

BACKGROUND

Prior studies have suggested that dementia adversely influences clinical outcomes and increases resource utilization in patients hospitalized for acute diseases. However, there is limited population-data information on the impact of dementia among elderly hospitalized patients with sepsis.

METHODS

From the 2009-2011 National Hospital Discharge Database we identified hospitalizations in adults aged ≥65 years. Using ICD9-CM codes, we selected sepsis cases, divided them into two cohorts (with and without dementia) and compared both groups with respect to organ dysfunction, in-hospital mortality and the use of hospital resources. We estimated the impact of dementia on these primary endpoints through multivariate regression models.

RESULTS

Of the 148 293 episodes of sepsis identified, 16 829 (11.3%) had diagnoses of dementia. Compared to their dementia-free counterparts, they were more predominantly female and older, had a lower burden of comorbidities and were more frequently admitted due to a principal diagnosis of sepsis. The dementia cohort showed a lower risk of organ dysfunction (adjusted OR: 0.84, 95% Confidence Interval [CI]: 0.81, 0.87) but higher in-hospital mortality (adjusted OR: 1.32, 95% [CI]: 1.27, 1.37). The impact of dementia on mortality was higher in the cases of younger age, without comorbidities and without organ dysfunction. The cases with dementia also had a lower length of stay (-3.87 days, 95% [CI]: -4.21, -3.54) and lower mean hospital costs (-3040€, 95% [CI]: -3279, -2800).

CONCLUSIONS

This nationwide population-based study shows that dementia is present in a substantial proportion of adults ≥65s hospitalized with sepsis, and while the condition does seem to come with a lower risk of organ dysfunction, it exerts a negative influence on in-hospital mortality and acts as an independent mortality predictor. Furthermore, it is significantly associated with shorter length of stay and lower hospital costs.
