Serum NFL in PD according to motor and cognition severity. (A) Mean serum NFL level was significantly elevated in patients with PD who displayed severe motor disorder based on the H-Y stage (p < 0.01). (B) Mean serum NFL level was markedly higher in patients with PDD compared to PD-MCI, PD-NC and control. Mean levels are shown with SD; *p < 0.01. H-Y = Hoehn & Yahr; MCI = mild cognitive impairment; NFL = neurofilament light chain; PD = Parkinson disease; PDD = PD with dementia; PD-NC = PD with normal cognition
