Associations of Monocyte Glucocerebrosidase with Cognition and Cholinergic Innervation in GBA1 Parkinson's Disease

Key Points

The research aims to investigate the relationship between monocyte glucocerebrosidase activity and cognitive decline in early-stage Parkinson's Disease.
Analyzed monocytic GCase activity in relation to cognition and cholinergic innervation in patients with Parkinson's Disease.
Evaluated peripheral measurements and their correlation with central cholinergic dysfunction.
Assessed cognitive decline using established cognitive assessment tools.
Monocytic GCase activity did not correlate with cognitive decline in early-stage Parkinson's Disease.
No significant link was found between GCase activity and regional cholinergic denervation.
Peripheral measurements are not indicative of central cholinergic dysfunction.

Abstract

Monocytic GCase activity does not appear to be a reliable biomarker for cognitive decline in early-stage PD and is not linked to regional cholinergic denervation. Peripheral measurements do not reflect central processes underlying cholinergic dysfunction. © 2026 The Author(s).
