Summary: This article reviews the discovery and development of biomarkers for Alzheimer's disease (AD), discussing the use of cerebrospinal fluid (CSF) and blood-based biomarkers. The proposed ATN scheme may provide a common language for researchers studying AD. Blood-based biomarkers offer a promising alternative to CSF biomarkers.

Summary: The study reviews and summarizes the physiological and pathophysiological functions, structures, and genetics of alpha-syn in Alzheimer's disease (AD). Numerous associations of alpha-syn with A beta and tau suggest its significance as a partner in the pathological roles of AD. Understanding the involvement of alpha-syn in the pathology of A beta and tau could help address unresolved issues of AD. Specifically, the current status of CSF alpha-syn in AD recommends it as an additional biomarker in AD diagnosis.

Summary: Alzheimer's disease is a prevalent neurodegenerative disorder characterized by progressive deterioration, loss of neurons, and cognitive decline. Amyloid beta and Tau proteins are key biomarkers of the disease, and their abnormal levels in biofluids, particularly cerebrospinal fluid, are directly linked to the incidence and progression of Alzheimer's. Developing sensitive and reliable methods for screening and evaluating these biomarkers in cerebrospinal fluid can aid in early diagnosis and treatment. This article discusses the impact of Alzheimer's on cerebrospinal fluid and provides an overview of the latest biosensors for detecting amyloid beta and Tau in cerebrospinal fluid samples.

Summary: This study found that levels of A beta 42 and pTau in cerebrospinal fluid are more direct indicators of the pathogenesis of Alzheimer's disease than clinical diagnosis. Through a collaborative effort, novel associations with AD risk loci and multiple biological pathways related to A beta 42 and pTau were identified.

Summary: CSF t-tau is a reliable biomarker for sCJD, but false positive results may occur, especially in rpAD and acute encephalopathies. The t-tau/p-tau ratio may improve the diagnostic accuracy in centers where specific biomarkers are not available.

Summary: Late-onset and early-onset dementia exhibit neurobiological and clinical differences. This study compared the clinical and FDG-PET features of posterior cortical atrophy (PCA), the visual variant of Alzheimer's disease, between late-onset and early-onset cases. The results showed that the main difference between the two groups was a higher prevalence of Balint-Holmes symptoms in the early-onset cases, which was associated with severe bilateral occipito-temporo-parietal hypometabolism. In the late-onset cases, there was a reduction of FDG uptake mainly in the right posterior regions. Age was found to be correlated with metabolism in different brain regions.

Summary: This study investigated the relationship between A beta 42/A beta 40 ratios and cerebral A beta pathology using App knock-in mouse models. The results showed a negative association between A beta 42/A beta 40 ratios and cerebral A beta plaque burden in App(NL-F/NL-F) mice, with stronger correlations observed in CSF compared to serum. Additionally, the decline in A beta 42/A beta 40 ratios in CSF and serum occurred after the deposition of A beta aggregates in the brain reached significance. However, no similar changes were observed in App(NL/NL) mice.

Summary: This study aimed to investigate the potential influence of different storage conditions on the quantification of biomarkers related to Alzheimer's disease in cerebrospinal fluid. The results showed that temperature and storage days significantly impacted the concentrations of certain biomarkers. However, the use of a ratio between two biomarkers could partially compensate for this influence. Other biomarkers were not affected by the tested storage conditions. The findings suggest that specific correction factors can be applied for samples stored at 4 degrees C.

Summary: This study assessed the use of cerebrospinal fluid (CSF) biomarkers as an alternative to positron emission tomography (PET) for confirming brain amyloid beta (A beta) pathology. The results showed a robust concordance between CSF biomarkers and amyloid PET, and the ratios of CSF biomarkers exhibited higher diagnostic accuracy for A beta pathology confirmation.

Summary: Posterior cortical hypometabolism measured with F-18-fluorodeoxyglucose (FDG)-PET is a marker of neurodegeneration in Alzheimer's disease, and it is mainly associated with structural neurodegeneration and tau pathology, rather than amyloid pathology.

Summary: The number of patients with Alzheimer's disease (AD) and non-AD has increased significantly in recent decades. The amyloid cascade hypothesis highlights the role of amyloid-beta protein in the development of AD. CSF A beta(42/40) has been extensively studied and integrated into diagnostic tools for AD, while blood-based A beta(42/40) has also been found to have abnormal levels in sync with CSF biomarker values.

Summary: This study aimed to develop the first German-language adaptation of TASIT-SIM, an ecologically valid test for assessing Theory of Mind (ToM) abilities in healthy adults. Thirteen scenes were selected and filmed at different intensities to determine the best materials for the test. Through Rasch analysis, intensity versions were chosen that showed optimal performance in participants with medium ToM abilities. In conclusion, the Basel Version of the Awareness of Social Inference Test - Theory of Mind (BASIT-ToM) was developed, incorporating the strengths of TASIT-SIM and addressing its limitations. Further validation of BASIT-ToM is needed in both healthy and clinical populations.
