Summary: This study explored the cognitive decline and dementia outcomes among same-sex and mixed-sex couples. The results showed that both groups experienced cognitive decline regardless of baseline diagnosis. Generally, there were no statistically significant differences between the same-sex and mixed-sex groups in terms of functioning, dementia severity, or neuropsychological testing, except for two exceptions. Participants with mild cognitive impairment in same-sex relationships showed less functional impairment at baseline, while the same-sex group with dementia had a slower decline in attention/working memory. Therefore, there were no cognitive health disparities among same-sex couples consistent with a minority stress model. Further research on protective factors is needed.

Summary: Neuropsychiatric symptoms (NPS) have been identified as risk factors for conversion to Alzheimer's disease (AD) and other dementia types in patients with Mild Cognitive Impairment (MCI). Four NPS profiles emerged based on prominent symptoms in MCI patients, with Irritability and Apathy being predictors of dementia conversion. The findings suggest that NPS can be used as early diagnosis facilitators and to identify different illness trajectories in MCI progression.

Summary: Cognitive impairment is a serious condition associated with aging and disruption of inflammation and innate immunity. Recent studies have shown that the innate immune system is prevalent in patients with Alzheimer's disease, and peripheral neutrophil markers can predict a decline in cognitive function in patients with mild cognitive impairment. Furthermore, altered levels of pro-inflammatory interleukins have been reported in patients with mild cognitive impairment, potentially playing a role in the progression from early cognitive impairment to dementia.

Summary: The study found that older adults with mild cognitive impairment (MCI) exhibited reduced parasympathetic function during non-rapid eye movement sleep, especially in those with amnestic MCI. This may serve as an early biomarker for dementia detection.

Summary: This study aimed to investigate the association between the change in white matter hyperintensities (WMH) burden and conversion to dementia in individuals with mild cognitive impairment (MCI) who are either amyloid-positive (A & beta;+) or amyloid-negative (A & beta;-). The results showed that individuals with A & beta;+ had the highest increase in WMH burden and steepest accumulation over time compared to individuals with A & beta;-.

Summary: Physical activity has a positive effect on cognition in people with dementia and mild cognitive impairment, especially in terms of global cognition. Positive effects were also shown on executive function and memory, confirming the relevance of physical activity in the treatment of cognitive impairment.

Summary: Mild cognitive impairment (MCI) is a clinical condition with a high risk of progressing to dementia. Early diagnosis and intervention at the MCI stage are considered critical strategies in disease management. Lack of consensus on guidelines for routine screening of MCI leads to a considerable number of undiagnosed patients in the community.

Summary: Cognitive training is a potential technique for treating cognitive impairment caused by neurological injury and disease. Different training methods have different mechanisms of action and engage distinct brain regions. Mnemonic strategy training (MST) showed superior effects in the short term and increased activation and functional connectivity in multiple brain regions.

Summary: This study aimed to investigate the prevalence and differentiating features of Mild Behavioral Impairment (MBI) with respect to major neurocognitive disorders (MNDs) and primary psychiatric disorders (PPDs). The results showed that patients with MBI had higher scores of psychopathology, specifically in terms of negative symptoms, compared to patients with PPDs. Additionally, MBI patients frequently reported higher severity of apathy and motor retardation.

Summary: The visual cognitive assessment test (VCAT) is a language-neutral screening tool for detecting MCI/mild dementia. This meta-analysis showed that VCAT demonstrated acceptable diagnostic accuracy in distinguishing MCI/mild dementia in cognitively normal older adults.

Summary: This study proposed a two-stage screening frame for high-risk MCI subjects, finding that ADAS-13 was more sensitive for filtering out high-risk individuals. The optimal model included a change rate of clinical assessments and three neuroimaging measurements, significantly associated with a net reclassification improvement (NRI) of 0.246 and integrated discrimination improvement (IDI) of 0.090. The ADAS-13 longitudinal models had the best discrimination performance.

Summary: Timely diagnosis of cognitive impairment is a key goal of the National Plan to Address Alzheimer's Disease, but studies on factors contributing to timely diagnosis are limited. This retrospective observational study found that only 26% of respondents with incident dementia and 11.4% with incident MCI received a timely diagnosis. Non-Hispanic Black and individuals with lower educational attainment were less likely to receive timely diagnosis of dementia or MCI compared to Non-Hispanic White respondents or those with a college degree.

Summary: Through FAQ assessment, it was found that PD-MCI patients had more difficulties with tax records and traveling, while AD-MCI patients were more impaired in managing finances and remembering appointments. The classification accuracy of the FAQ differed between MCI related to PD and AD.

Summary: This article discusses a recent study that suggests using a miRNA triad, consisting of miR-181a-5p, miR-146a-5p, and miR-148a-3p, for diagnosing ACI, MCI, and AD. The study explores the impact of elevated levels of this miRNA triad on neural plasticity and cognitive function in the brain and the potential of inhibiting it to improve cognitive function in MCI and AD.

Summary: Modeling censored survival data involves estimating the conditional hazard function through parametric or semiparametric models, with the latter allowing for a weaker assumption of hazard proportionality. Kernel estimation can verify assumptions and capture changes in the hazard function over time and covariates.

Summary: The advent of high-resolution imaging has made data on surface shape widespread, leading to the need for a functional approach in shape analysis. Three innovative forms of analysis are introduced, including surface integration, focusing on sub-spaces with interesting behavior, and comparing individual shapes with a relevant control set. These ideas are particularly useful in medical contexts for assessing individual patients.

Summary: Protein kinases (PKs) are extensively studied drug targets, particularly in the field of oncology and neurodegeneration. Tau protein hyperphosphorylation, a post-translational modification observed in Alzheimer's disease (AD), highlights the involvement of PKs in neurodegeneration. The efficacy of protein kinase inhibitors (PKIs) and protein phosphatase 2 A (PP2A) activators in AD has been investigated in preclinical and clinical studies, but the outcomes have been variable. This review examines the results of these studies and evaluates the potential of targeting tau hyperphosphorylation as a disease modifying therapy.
