Summary: Dementia is a major cause of death and disability worldwide. A global cost model was constructed to estimate the total societal costs of dementia, including direct and indirect economic costs. In 2019, the annual global societal costs of dementia were estimated to be $1313.4 billion, with the highest costs seen in high-income countries.

Summary: This study analyzed the influence of apathy on resource utilization in patients with dementia of the Alzheimer's type. The findings suggest that apathy is a significant factor driving costs in mild to moderate dementia. Effective treatment of apathy may lead to reduced overall costs in Alzheimer's disease.

Summary: Population ageing is a global social phenomenon where the risk of dementia may be changing in certain countries and areas. This systematic review examined recent observations of a possible decrease in dementia frequency in some Western countries between 1977 and 2014. The studies included had heterogeneity in clinical criteria and methodological quality.

Summary: The study found a higher incidence of dementia in rural China than previously reported, with rates increasing with age and AD being the most common type of dementia. Poor education was associated with increased risk of VaD and AD, while engagement in social activities was identified as an independent protective factor for VaD.

Summary: This article discusses the potential role of microorganisms in the development of Alzheimer's disease, focusing on whether Lyme disease is a cause of Alzheimer's disease or Lewy body dementia. The paper concludes that there is no convincing evidence supporting a causal relationship between Lyme disease and either Alzheimer's disease or Lewy body dementia.

Summary: Home health (HH) is an important source of care for early-stage/undiagnosed Alzheimer's Disease and Related Dementias (ADRD) patients. This study aims to investigate the prevalence and predictors of incident ADRD diagnosis following HH. The results show that 10% of HH patients without diagnosed ADRD received an incident diagnosis within 1 year. Furthermore, HH patients with impaired overall cognition and community-referred patients were more likely to receive an incident ADRD diagnosis.

Summary: The study found that low and high plasma magnesium concentrations were associated with high risk of vascular-related non-Alzheimer dementia, with the lowest risk observed at a concentration of 2.07mg/dL. No association was observed for Alzheimer dementia. Mediation analysis suggested that diabetes may be in the causal pathway between low plasma magnesium concentrations and high risk of non-Alzheimer dementia.

Summary: This focused review provides an update on current magnetic resonance imaging methods for measuring cerebrovascular disease lesions and early cerebrovascular disease-related brain injury. It discusses the clinical implications and relevance of these imaging markers for cognitive decline, incident dementia, and disease progression in Alzheimer's disease and related dementias. The review also presents the outlook and challenges in the field.

Summary: Epilepsy affects approximately 1% of the world population, and despite the availability of many antiepileptic drugs, a significant number of patients do not respond to treatment or show high pharmacokinetic variability, emphasizing the importance of therapeutic drug monitoring (TDM). A novel HPLC-DAD technique was developed in this study to quantify multiple antiepileptic drugs in human saliva, demonstrating sensitive drug quantification and a potential new approach for individualized treatment monitoring and assessing patient adherence.

The mutation may affect mRNA secondary structure and stability, thus potentially influencing MEF2C protein levels.

Summary: The Toulouse-Pieron Cancelation Test (TP) is a classic psychometric tool used for assessing selective/sustained attention, processing speed, and visuo-perceptual abilities. This study provides normative scores for the TP in a sample of Portuguese healthy adults, finding that education is a major predictor of TP-WE and TP-DI.

Summary: The study on FTD and its subtypes found that levels of NfL in CSF and serum can serve as biomarkers for the disease and are associated with cognitive decline. Genetic cases, especially FTD-GRN, have higher NfL levels. These findings suggest that NfL may have potential value in evaluating disease severity and developing therapies for FTD.

Summary: Frontotemporal dementia in genetic forms is highly heterogeneous and begins many years prior to symptom onset. This study used an unsupervised machine learning algorithm, cTI, to analyze large-scale population datasets and obtained individual scores of disease stage based on MRI metrics. The results suggest that cTI can identify data-driven disease stages in genetic forms of frontotemporal dementia.

Summary: In Portugal, there is a lack of gold standard tests to assess acute stroke patients in hospitals. Cognitive deficits are common after stroke and have a negative impact on a patient's quality of life and rehabilitation. This study aimed to adapt the Oxford Cognitive Screening to European Portuguese speakers (OCS-Pt), establish normative data cut-offs, and evaluate the psychometric properties of OCS-Pt. Results showed that OCS-Pt is a promising cognitive screening tool for acute stroke survivors in Portugal.

Summary: This study aims to estimate the prevalence of amyloid abnormality in individuals with different cognitive statuses and examine the factors that may affect these estimates. The results show that CSF-based estimates using adjusted data-driven cutoffs were higher than PET-based estimates in individuals without dementia, suggesting that preclinical and prodromal AD may be more prevalent than previously estimated. This finding has important implications for clinical trial recruitment strategies and healthcare planning policies.

By analyzing 320,444 women who had reached menopause between 1990 and 2018 in a free breast cancer screening program, it was found that the median age at menopause has been increasing and there are regional differences among different percentile ranges.

Summary: This study evaluates the efficacy of inhibiting or reducing histone deacetylases (HDACs) in Alzheimer's disease (AD) models by modifying gene transcription. The results show that inhibiting class I HDACs can ameliorate ER-mitochondria cross-talk in AD by normalizing calcium signaling between the two organelles. The selective HDAC inhibitor, Tacedinaline (Tac), counteracted the impaired ER-mitochondria communication and reduced amyloid beta levels in AD cells and animal models. These findings suggest that transcriptional regulation of ER-mitochondria communication could be a promising target for innovative therapeutics in AD.
