The clinical manifestations of LRRK2-related PD have been described as being more benign than those shown in idiopathic PD, where motor symptoms (disease severity, rate of progression, occurrence of falls, and dyskinesia) and non-motor symptoms (cognition and olfaction) are less severe (17), whereas familial PD caused by LRRK2 have been described as being similar to idiopathic PD (18). This evidence concerns the gene LRRK2 and drug-induced dyskinesia.
