Background: Dementia is a growing global health challenge, with significant socioeconomic implications. This study examined the informal care duration and related costs along with the total cost of care for older individuals with dementia in Benin, West Africa, providing insights into a region with limited dementia research.
Methods: We conducted a cost-of-illness study in Benin. Both hospital and community recruitments were used to enroll adults aged ≥60 years and their primary caregivers. Structured questionnaire and validated tools were used to collect the demographic, clinical, healthcare resource utilization data as well as informal care duration. Replacement costs approach was performed to valuate informal care time. Official exchange rates from the World Bank were used to convert costs from local currency to purchasing power parities dollars (PPP$).
Results: Data from 135 individuals with varying dementia stages revealed that dementia places substantial caregiving demands, predominantly on women who provide up to 8 h of daily care. In 2021, the mean annual cost of dementia care was estimated to be PPP$ 2,399.66 ± 2,057.07. Informal care represented a significant portion of dementia expenses, up to 92% of the total care costs in this study.
Discussion: Policy interventions are urgently needed to address the dementia care challenges in Benin, especially because economic transitions and educational advancements may reduce the availability of informal caregivers. This emphasizes the vital role of informal caregivers and underscores the need of implementing dementia policies to support families facing the evolving challenges of dementia care.
Introduction: Older individuals with a higher cardiovascular disease (CVD) burden have a higher risk for accelerated cognitive decline and dementia. Physical activity (PA) is an inexpensive and accessible preventive measure to CVD, cognitive impairment, and dementia. The current study examined (1) whether PA moderates the relationship between CVD burden and cognition and (2) whether the moderating effect of PA differs by race/ethnicity groups and by APOE-ɛ4 status.
Methods: Our cross-sectional study included participants from the Washington Heights-Inwood Columbia Aging Project (WHICAP), a multiethnic, community-based, longitudinal study on aging and dementia among individuals aged 65 years and older who reside in northern Manhattan. All participants underwent an interview and a neuropsychological assessment for global cognition, memory, language, visuospatial, and speed functioning.
Results: In 2,122 older individuals without dementia, having a higher CVD burden was associated with worse cognitive scores for global, language, speed, and visuospatial cognitive functions. PA mitigated the relationship between CVD burden and visuospatial function. Furthermore, PA mitigated the association of CVD burden with global cognition, language, and visuospatial functions in APOE-ɛ4 carriers but not in non-carriers.
Discussion/conclusion: Our study suggests that PA may mitigate the negative association between CVD and cognition, especially in APOE-ɛ4 carriers. The moderating effect of PA did not differ by race/ethnicity.
Background: Stroke is a leading cause of acquired disability in adults worldwide, and the burden of stroke is projected to increase. Current long-term stroke outcome data including functional status, activity, and participation limitations as well as information on health-related quality of life (HRQoL) are vital for future rehabilitation and resource planning of stroke survivors.
Methods: First-ever stroke survivors from a population-based cohort with ischemic stroke or intracerebral hemorrhage were followed up 3-4 years after stroke onset via clinic appointments, home visits, or telephone. Ischemic stroke was stratified by clinical syndrome (Oxfordshire Community Stroke Project classification) and pathogenetic mechanism (TOAST classification). We assessed the participants' functional status and independence with the modified Rankin Scale (mRS) and Barthel Index (BI) and their HRQoL across several domains (Short Form Questionnaire-36, EuroQoL-5D, and Stroke Impact Scale (SIS)). We used logistic and linear regression analyses to analyze potential baseline predictors of 3-4-year outcome.
Results: Four hundred individuals were included; 151 died before clinical follow-up and 47 (12%) were lost to detailed follow-up. Two hundred and two individuals (median age: 72, IQR: 65-79; 40% female) were followed up after a median of 3.2 years (IQR: 3.1-3.5). Nineteen individuals (9%) had a recurrent stroke during the 3-4-year follow-up period. Among the 202 follow-up attendees, 147 (73%) had favorable functional outcome (mRS ≤2) and 134 (69%) of the 195 respondents reported good-excellent HRQoL according to SF-36. Age (HR: 1.03; 95% CI: 1.00-1.05), initial stroke severity (HR: 1.16; 95% CI: 1.10-1.22; p < 0.001), living with in-home care or in care facility at baseline (HR: 8.77; 95% CI: 2.98-25.64), and recurrent stroke (HR: 3.58; 95% CI: 1.47-8.77) were predictors of poor functional outcome (mRS>2). Poor functional outcome/death was less common among IS due to Other Causes and Small Artery Occlusion than other pathogenetic mechanisms (20% and 33% vs. 56-68%; p < 0.01). SIS respondents with poor functional outcomes (n = 32) reported worst outcome in the hand domain of SIS (median: 28/100; IQR: 0-73).
Conclusions: Most 3-4-year stroke survivors have favorable functional outcomes and are independent in ADL in a population-based cohort. Despite its relative rarity, recurrent stroke was a predictor of poor functional outcome, emphasizing the need of adequate secondary prevention.
Background: The gut microbiota (GM) of the human body comprises several species of microorganisms. This microorganism plays a significant role in the physiological and pathophysiological processes of various human diseases.
Methods: The literature review includes studies that describe causative factors that influence GM. The GM is sensitive to various factors like circadian rhythms, environmental agents, physical activity, nutrition, and hygiene that together impact the functioning and composition of the gut microbiome. This affects the health of the host, including the psycho-neural aspects, due to the interconnectivity between the brain and the gut. Hence, this paper examines the relationship of GM with neurodegenerative disorders in the context of these aforesaid factors.
Conclusion: Future studies that identify the regulatory pathways associated with gut microbes can provide a causal link between brain degeneration and the gut at a molecular level. Together, this review could be helpful in designing preventive and treatment strategies aimed at GM, so that neurodegenerative diseases can be treated.
Introduction: Survivors of stroke are at risk of experiencing subsequent major adverse cardiovascular events (MACE). We aimed to determine the incidence of, and risk factors for, MACE after first-ever ischemic stroke, by age group (18-64 years vs. ≥65 years).
Methods: Observational cohort study using patient-level data from the Australian Stroke Clinical Registry (2009-2013), linked with hospital administrative data. We included adults with first-ever ischemic stroke who had no previous acute cardiovascular admissions and followed these patients for 2 years post-discharge, or until the first post-stroke MACE event. A Fine-Gray sub-distribution hazard model, accounting for the competing risk of non-cardiovascular death, was used to determine factors for incident post-stroke MACE.
Results: Among 5,994 patients with a first-ever ischemic stroke (median age 73 years, 45% female), 17% were admitted for MACE within 2 years (129 events per 1,000 person-years). The median time to first post-stroke MACE was 117 days (89 days if aged <65 years vs. 126 days if aged ≥65 years; p = 0.025). Among patients aged 18-64 years, receiving intravenous thrombolysis (sub-distribution hazard ratio [SHR] 0.51 [95% CI, 0.28-0.92]) or being discharged to inpatient rehabilitation (SHR 0.65 [95% CI, 0.46-0.92]) were associated with a reduced incidence of post-stroke MACE. In those aged ≥65 years, being unable to walk on admission (SHR 1.33 [95% CI 1.15-1.54]), and history of smoking (SHR 1.40 [95% CI 1.14-1.71]) or atrial fibrillation (SHR 1.31 [95% CI 1.14-1.51]) were associated with an increased incidence of post-stroke MACE. Acute management in a large hospital (>300 beds) for the initial stroke event was associated with reduced incidence of post-stroke MACE, irrespective of age group.
Conclusions: MACE is common within 2 years of stroke, with most events occurring within the first year. We have identified important factors to consider when designing interventions to prevent MACE after stroke, particularly among those aged <65 years.
Background: Population-based studies examining the prevalence of trigeminal neuralgia (TN) and persistent idiopathic facial pain (PIFP) are rare, and data on TN prevalence in Türkiye are very limited, with the prevalence of PIFP being unknown. This study aimed to determine the prevalence of TN and PIFP in Türkiye.
Materials and methods: This population-based epidemiological study has a cross-sectional and descriptive design, and it was carried out in Afyonkarahisar, Türkiye. Participants aged 18 years and older were screened by using a self-assessment form to determine potential patients with TN or PIFP.
Results: A total of 19,237 individuals were included in this study, of which 17,223 responded to the survey questions. TN was diagnosed in 17 individuals, and the prevalence of TN was calculated as 98.5 per 100,000. PIFP was diagnosed in 35 patients, and the prevalence of PIFP was calculated as 202 per 100,000. The mean age of the patients with TN was 54.29 ± 12.98 years, the mean age of patients with PIFP was 49.80 ± 16.10 years, and the female-to-male ratio was 1.13/1 for TN and 2.18/1 for PIFP.
Conclusion: The prevalence of PIFP in Türkiye has been reported for the first time by this study. Additionally, a much higher prevalence of TN was found when compared to previous study.
