Neurocysticercosis and cognitive impairment among people with epilepsy in Taenia solium endemic regions of rural southern Tanzania: A hospital-based cross-sectional study in mental health clinics of selected sites in Tanzania. Epilepsy Behav 2024; 159:110010. [PMID: 39186856 DOI: 10.1016/j.yebeh.2024.110010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Revised: 07/20/2024] [Accepted: 08/20/2024] [Indexed: 08/28/2024]
Abstract
BACKGROUND Epilepsy poses a significant public health problem in many parts of the world. The majority of people with epilepsy (PWE) are from low-income and middle-income countries (LMICs). Taenia solium neurocysticercosis (NCC) is estimated to cause 30% of preventable epilepsy in PWE in areas of T. solium endemicity. This study was conducted to assess the prevalence of NCC in PWE, evaluate the presence of cognitive impairment in PWE and assess potentially contributing factors. METHODS PWE were recruited within a mental health clinic-based cross-sectional study in rural Southern Tanzania. PWE underwent a detailed neurological examination, including mental state, and a blood sample was collected for T. solium cysticercosis (CC) serology testing. Patients who were serologically positive for CC and those detected to have prominent neurological deficits apart from epilepsy were invited to receive a cerebral computed tomography (CT) examination. RESULTS Out of the 223 people with epilepsy (PWE) recruited, 221 underwent clinical examination. Among these, 26 (11.8 %) had cognitive impairment, and 2 had neurological signs or symptoms without cognitive impairment. Twenty-five of the 223 PWE (11.2 %) tested positive for CC, of which 4 had cognitive impairment. One hundred and ninety-eight (88.8 %) tested negative for CC, of which 22 had cognitive impairment. A total of 36 participants underwent CT scans, with 18 testing positive and 18 testing negative for CC. Of the 36 who had CT scans, 8 (22.2 %) were diagnosed with NCC; 7 were CC positive, and 1 was CC negative; only the latter had cognitive impairment. Multivariate logistic regression confirmed that cognitive impairment in PWE was 8.62 times higher for Kongwa participants than Chunya, with a statistically significant association (95 % CI: 1.75, 156; p = 0.037). Additionally, having and education was associated with a 91 % reduction in the odds of cognitive impairment (OR = 0.09) compared to no education, which was also statistically significant (95 % CI: 0.01, 0.33; p = 0.002). There was no association between cognitive impairment and NCC. CONCLUSION Our study found a 22.2 % prevalence of NCC among PWE. Cognitive impairment was present in 11.8 % of PWE but was not significantly associated with NCC. Socioeconomic and educational factors may play a larger role in cognitive impairment among PWE.

Abstract
Introduction Key component of early detection of dementia is a brief and culturally appropriate cognitive screening tool. This study aimed to perform a cultural adaptation of the Brief Cognitive Screening Battery (BCSB) and to obtain normative data from the older adult population. Methods Cross-cultural adaptation process to develop BCSB-INA was performed. This was followed by a feasibility study from community dwelling older adults from several urban and rural areas in North Sumatra, Indonesia. Results The BCSB-INA was generally well understood and showed not much discrepancy in translation from the original version. There were differences in semantic and phonemic fluency and CDT based on years of education, but no difference was found on other domain, including the delayed recall of the FMT. The battery was more influenced by age than education. Discussion The BCSB-INA is culturally appropriate and feasible to be used in population with heterogenous educational background in Indonesia.

Abstract
With the worldwide increase in life span, surgical patients are becoming older and have a greater propensity for postoperative cognitive impairment, either new onset or through deterioration of an existing condition; in both conditions, knowledge of the patient's preoperative cognitive function and postoperative cognitive trajectory is imperative. We describe the clinical utility of a tablet-based technique for rapid assessment of the memory and attentiveness domains required for executive function. The pathogenic mechanisms for perioperative neurocognitive disorders have been investigated in animal models in which excessive and/or prolonged postoperative neuroinflammation has emerged as a likely contender. The cellular and molecular species involved in postoperative neuroinflammation are the putative targets for future therapeutic interventions that are efficacious and do not interfere with the surgical patient's healing process.

The physician's Alzheimer's disease management guide: Early detection and diagnosis of cognitive impairment, Alzheimer's disease and related dementia. AIMS Public Health 2022; 9:661-689. [PMID: 36636148 PMCID: PMC9807411 DOI: 10.3934/publichealth.2022047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 09/07/2022] [Accepted: 09/13/2022] [Indexed: 01/16/2023] Open
Abstract
Primary care professionals play a critical role in the care of their patients. In clinical practice, early detection and diagnosis of Mild Cognitive Impairment, Alzheimer's disease and related dementia are often missed or delayed. Disclosure of diagnosis is not timely or not revealed. Though the methods that could improve early detection and diagnosis have remained the same over the decades with little change, they provide opportunities for early intervention, treatment and improvement in patient care. Emerging research suggests that though the disease process begins years prior to the clinical diagnosis, the healthcare system and health care professionals remain distant and reluctant to provide the service of annual cognitive assessment, which has been recommended by the Medicare program for older adults aged 65 years and older. Findings support that Alzheimer's disease and related cognitive impairments have gone under detected, underdiagnosed and undertreated. This article seeks to provide valuable and equitable information in the form of a clinician's guide for removing the barriers to early detection and diagnosis of cognitive impairments and offers an unprecedented opportunity to improve the clinical outcomes and care of older adults with various levels of cognitive decline, including mild cognitive impairment, Alzheimer's disease, and related dementias. This article provides information on understanding and addressing the challenges faced by health care professionals, including primary care clinicians; removing the barriers to cognitive assessments; educating this professional group on the importance of brain health, early detection, and diagnosis for their older adult patients; and providing these professionals with the ability to transfer their knowledge into more defined care planning. Until cognitive screening has been fully accepted and implemented for the optimal the care of older adults, health-related efforts should include the promotion and education of brain health, early detection, and diagnosis in the education of health care providers.

[PMID: 35779574 DOI: 10.1016/j.jamda.2022.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 05/23/2022] [Accepted: 05/24/2022] [Indexed: 10/17/2022]
Abstract
OBJECTIVE To examine the association between B vitamins status and the risk of dementia in older adults through a systematic review and meta-analysis of cohort studies. DESIGN Systematic review and meta-analysis. SETTING AND PARTICIPANTS Older adults aged ≥60 years from community, nursing home, institution, or hospital. METHODS PubMed, Cochrane Library, EMBASE, Web of Science, CINAHL, ClinicalTrials, WHO-ICTRP, NHS Trusts, and ACTR were searched from the date of their inception up to November 28, 2021. We included cohort studies that assessed the association between serum B vitamins or B vitamins intake and the risk of dementia among older adults aged ≥60 years. The quality of all studies was assessed by the modified Newcastle-Ottawa Scale (NOS). The hazard ratios (HRs) and 95% CIs were calculated by the random effects model. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach was used to rate the certainty of evidence. RESULTS Eleven cohort studies with sample sizes ranging from 233 to 3634 were included in the meta-analysis. Levels of serum folate showed statistically significant association with the risk of dementia (≥10 nmol/L: HR 1.57, 95% CI 1.01-2.46, low certainty; <10 nmol/L: HR 0.93, 95% CI 0.88-0.99, very low certainty). However, levels of vitamin B6 intake showed no statistically significant effects on risk of dementia; levels of serum vitamin B12 and vitamin B12 intake also showed no statistically significant effects on risk of dementia in older adults. CONCLUSIONS AND IMPLICATIONS The results from our meta-analysis suggest that vitamin B6, B12, and folate may not be modifiable risk factors for dementia among older adults. Current evidence on the relationship between vitamin B status and dementia is not sufficient for development of vitamin B recommendations. More high-quality cohort studies are needed to confirm the relationship between the two in the future.

Abstract
Objectives Dementia poses one of the greatest global health challenges, affecting 50 million people worldwide. With 10 million new cases each year, dementia is a growing burden, particularly in low- and middle-income countries (LMIC). This study aimed to identify the facilitators and barriers to providing quality dementia assessment and care in LMICs from a global health perspective. Methods/Design A qualitative semi-structured interview study with 20 dementia expert healthcare providers from 19 countries. To be included, providers had to: practice dementia assessment or care in LMICs where the population over age 60 is projected to more than double by 2050 and be recognized as a leading dementia expert in the region based on position, research publications, and/or policy leadership. Interviews were analyzed by a multidisciplinary team of researchers using thematic analysis. Results Barriers to dementia assessment and care included stigma about dementia, poor patient engagement in and access to healthcare, inadequate linguistic and cultural validation, limited dementia capable workforce, competing healthcare system priorities, and insufficient health financing. Facilitators included the rise in dementia awareness campaigns, dementia training for general practitioners, availability of family support and family caregivers, and national and international collaborations including coordinated policy efforts and involvement in international research initiatives. Conclusions Findings from this study provide insights for prioritizing dementia assessment and care capacity-building in LMICs as a global health priority and for tailored public health approaches to strengthen dementia assessment and care at the individual, community, national, and multi-national levels.
