BDNF rs6265 single-nucleotide polymorphism is involved in levodopa-induced dyskinesia in Parkinson's disease via its regulation of the cortical thickness of the left postcentral gyrus.

ABSTRACT:

Background

Brain-derived neurotrophic factor (BDNF) gene rs6265 single-nucleotide polymorphism (SNP) is thought to be involved in neuroplasticity and influence the development of levodopa-induced dyskinesia (LID) in Parkinson's disease (PD). This study aimed to determine how the BDNF rs6265 SNP regulates cortical thickness and to investigate the association between BDNF and the pathological mechanisms of LID in PD.

Methods

This cross-sectional study recruited 75 patients with PD, including 37 patients with LID and 38 patients without LID, and 33 healthy controls. All the participants underwent T1-weighted magnetic resonance imaging (MRI) scans, clinical evaluations, and BDNF rs6265 genotyping. Two-way factorial analysis of covariance (ANCOVA) was
