Percentage of correct responses on individual items between pre- and post-course evaluation. In the diagnosis domain, significant improvement of correct responses was observed in the following items; Q1: definite diagnosis of PD requires neuro-imaging confirmation; Q3: the presence of rest tremor is mandatory for the diagnosis of PD; and Q8: freezing of gait often precedes tremor and/or bradykinesia and dyskinesia (Q8). In the therapeutic options domain, significant improvement of correct responses were observed in the following items: Q16) the most effective drug available for PD is levodopa; Q17: levodopa has been shown to accelerate the progression of PD; Q19: dopamine agonists have definite evidence on slowing disease progression; and Q20: PD can be cured by deep brain stimulation surgery. In the disease course domain, significant improvement of correct responses was observed in the following items: Q22: wheelchair- or bed-bound is inevitable in PD; and Q25: deep brain stimulation surgery can stop PD progression
