Vascular Inflammation Is a Risk Factor Associated with Brain Atrophy and Disease Severity in Parkinson’s Disease: A Case-Control Study

Abstract

Patients with PD seem to have abnormal levels of vascular inflammatory markers and miRNAs in the peripheral circulation, and these levels are correlated with specific brain volume changes. This study reinforces the associations among peripheral inflammation, the BBB interface, and gray matter atrophy in PD and further demonstrates that BBB dysfunction with neurovascular impairment may play an important role in PD progression.
