Findings identify complement dysregulation, especially involving C1q, as an early correlate of tau-linked synaptic pathology, and support a role for complement activation in the AD molecular cascade.

In biomarker-confirmed AD, NREM SP and SO activity are associated with CSF orexin concentrations and moderate associations between orexin and longitudinal cognitive and neuropsychiatric outcomes, independent of Aβ42 and tau.

CSF p-tau205 as a biomarker of Alzheimer's disease pathology and progression with potential value for biological staging is supported and when incorporated into a conceptual CSF-based staging model, the final p-tau205-positive stage showed the strongest association with cortical atrophy, cognitive impairment, and risk...

Frontotemporal lobar degeneration (FTLD) is a common cause of early-onset dementias marked by progressive declines in behavior, cognition, and/or movement. FTLD neuropathologies, including TDP-43 proteinopathies and primary tauopathies, do not have reliable fluid biomarkers for in-vivo diagnosis nor biomarkers that dir...

Together, these experiments show that GarsΔETAQ/+ mice display robust and selective peripheral nerve pathology that manifests in a general distal-to-proximal fashion, priming this CMT2D allele for testing treatments and evaluating mechanisms underlying peripheral nerve vulnerability.

These findings highlight the complementary roles of CSF and plasma tau biomarkers in tracking disease progression: CSF biomarkers capture early pathological changes, whereas plasma biomarkers more effectively reflect disease progression within symptomatic stages.

This study provides Class II evidence that plasma NfL/p-tau217 discriminates patients with CJD from those with AD and Diagnosing AD with a single abnormal p-tau plasma biomarker risks misdiagnosing prion diseases as AD.
