Cholinergic Degeneration and Cognitive Function in Early GBA1‐Related Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective The phenotype of patients with Parkinson's disease carrying GBA1 variants (GBA‐PD) suggest similarities to symptomatology associated with early cholinergic system degeneration. Therefore, this study aims to investigate the clinical features and the cholinergic innervation pattern in patients with early GBA‐PD versus those without the GBA1 ...

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.
