Associations between antidiabetic medications and cerebrospinal fluid biomarkers of Alzheimer's disease.

Background: It has been hypothesized that insulin resistance is pivotal in mediating amyloid and tau dysregulations in Alzheimer's disease (AD).

Objective: To investigate the impact of different antidiabetic agents, their daily dosage intake, and treatment duration on cerebrospinal fluid (CSF) AD biomarkers among patients with type 2 diabetes.

Methods: This cross-sectional study selected patients between 50 and 80 years with diabetes and CSF AD biomarkers screened between 2017 and 2023 in the VALCODIS Cohort.

Fast Declining Prediction in Alzheimer's Disease from Early Clinical Assessment.

Intoduction: The heterogenicity in Alzheimer's Disease (AD) progression hinders individual prognosis. The present work is an observational 2-year longitudinal study in patients with mild cognitive impairment due to AD (n= 52, with positive CSF biomarkers). The aim of this study is to predict which patients are at risk of fast progression.

Defining Alzheimer's Disease through Proteomic CSF Profiling.

Alzheimer disease (AD) is the main cause of dementia, and its complexity is not yet completely understood. Proteomic profiles can provide useful information to explore the pathways involved and the heterogeneity among AD patients. A proteomic analysis was performed in cerebrospinal fluid (CSF) samples from mild cognitive impairment due to AD (MCI-AD) and control individuals; both groups were classified by amyloid β42/amyloid β40 levels in CSF (data available in BioStudies database (S-BSST1456)).

Insights from a 7-Year Dementia Cohort (VALCODIS): ApoE Genotype Evaluation.

The VALCODIS (Valencian Cognitive Diseases Study) cohort was designed and studied at the Hospital Universitari i Politècnic La Fe (Valencia, Spain) for the research of cognitive diseases, especially in the search for new biomarkers of Alzheimer's disease (AD). Participants in the VALCODIS cohort had cerebrospinal fluid (CSF) and blood samples, neuroimaging, and neuropsychological tests. The ApoE genotype was evaluated to identify its relationship with CSF biomarkers and neuropsychological tests in AD and non-AD participants.
