This review covers recent advances (2023-2024) in neuroimaging research into the pathophysiology, progression, and treatment of Alzheimer's disease (AD) and related dementias (ADRD). Despite the rapid emergence of blood-based biomarkers, neuroimaging continues to be a vital area of research in ADRD. Here, we discuss neuroimaging as a powerful tool to topographically visualize and quantify amyloid, tau, neurodegeneration, inflammation, and vascular disease in the brain.

Background: No standardized strategy for integrating κ-free light chain (κ-FLC) index into routine cerebrospinal fluid (CSF) diagnostics has yet been established.
Objective: To determine agreement between κ-FLC index and CSF-restricted oligoclonal bands (OCB), and to identify κ-FLC index range where second-line OCB testing is needed.
Methods: A retrospective analysis was conducted in patients who had κ-FLC measurement between December 2023 and December 2024 at the Medical University of Innsbruck.

Background: Alzheimer disease (AD) is characterized by amyloid-β plaques (A), tau tangles (T), and neurodegeneration (N), collectively defining the ATN framework. While imaging biomarkers are well-established, the prognostic value of plasma biomarkers in predicting cognitive decline remains underexplored. This study compares plasma and imaging A/T/N biomarkers in predicting cognitive decline and evaluate the impact of combining biomarkers across modalities.

Background: In relapsing-remitting multiple sclerosis (RRMS), the assessment of clinical disease activity can be challenging.
Objectives: To determine the diagnostic potential of serum neurofilament light (sNfL) and glial fibrillary acidic protein (sGFAP) to distinguish a relapse from other causes of deterioration.
Methods: In this multicenter, prospective study, RRMS patients with new neurological symptoms in the last 14 days were followed for 12 weeks.

Background: Exposure of mammals to ototoxic compounds causes hair cell (HC) loss in the vestibular sensory epithelia of the inner ear. In chronic exposure models, this loss often occurs by extrusion of the HC from the sensory epithelium towards the luminal cavity. HC extrusion is preceded by several steps that begin with detachment and synaptic uncoupling of the cells from the afferent terminals of their postsynaptic vestibular ganglion neurons.
