The Tau Global Conference 2025, hosted by the Alzheimer's Association, CurePSP, and the Rainwater Charitable Foundation, convened international experts from academia, industry, government, and philanthropy to explore advances and challenges in tauopathy research. The meeting highlighted progress across tau biology, including emerging models of tau regulation, degradation, and propagation; advances in biomarker development for the diagnosis and staging of tauopathies; and evolving therapeutic strategies targeting diverse aspects of tau pathophysiology.

Disruption of circadian rhythms is a key feature of neurodegenerative diseases and a non-motor feature of Parkinson's disease, which significantly impairs health-related quality of life; yet, the underlying mechanisms are only partially understood. Preclinical animal models with neuropathological and symptomatic significance might contribute to a better understanding of circadian dysfunction. [...]

Parkinson's disease (PD) is characterized by marked phenotypic heterogeneity particularly with regard to cognitive decline, which may be partly driven by ageing-related molecular pathways. Peroxisome Proliferator-Activated Receptor γ (PPARγ) represents a key downstream component of such pathways, while genetic variation in its coactivator gene peroxisome proliferator-activated receptor γ coactivator-1-α (PPARGC1A) may further modulate disease trajectories.

Psychiatric biomarker research is characterized by subtle but potentially informative biological signals that often lie close to methodological noise. Compared with neurodegenerative or infectious diseases, candidate blood and cerebrospinal fluid (CSF) markers in major psychiatric disorders often show small-to-moderate group differences, substantial patient-control overlap, and a more demanding path to clinical use.

Metacognition plays a crucial role in learning and decision-making across the life span. However, the neurophysiological substrates of metacognitive processes remain poorly understood. [...]

Transient insults to the brain can convert neurons chronically hyperexcitable. Key molecular mechanisms that link hypoxic events, e.g. [...]

Lactate, a well-known metabolite and signalling molecule, holds therapeutic potential for neurodegenerative diseases. Here, we investigated the effects of chronic lactate treatment on cognition and molecular biomarkers in the 5XFAD mouse model of Alzheimer’s disease (AD) and in wild-type (WT) controls using behavioural testing alongside proteomic and transcriptomic analyses. [...]

Implanted deep brain stimulation devices are now capable of chronically recording activity from intracranial brain areas during stimulation. This new type of data has the potential to increase our understanding of disease-related brain activity and its modulation in response to therapy or other types of stimuli. [...]

Traditional endpoints in acute ischaemic stroke trials, most commonly the mRS, incompletely capture the full spectrum of patient outcomes. The win ratio (WR) is a hierarchically structured composite outcome measure that prioritises endpoints according to clinical importance. [...]

Several medications are available for rapid tranquilisation in psychomotor agitation, but choosing among them varies across local practices and this variation is compounded by inconsistent guidelines. We performed a systematic review with individual participant data network meta-analysis to inform evidence-based recommendations.In this systematic review and individual participant data meta-analysis, we searched multiple databases from database inception to Nov 14, 2025, for randomised trials comparing intramuscular or intravenous treatments for rapid tranquilisation (primary outcome defined as sedation within 15-30 min) in patients with psychomotor agitation in general or psychiatric emergency settings.
