Brief Summary:
This study aims to verify transcranial direct current stimulation(tDCS) efficacy for Parkinson's disease (PD)-related dysphagia and its mechanism. Subjects are randomly split into two groups: control (sham tDCS + conventional dysphagia treatment) and experimental (real tDCS + conventional treatment).
Assessments will be conducted at baseline, after the completion of intervention, and at the 3-month follow-up. Swallowing function will be evaluated via gold-standard videofluoroscopic swallowing study (VFSS) and scales. Resting-state functional magnetic resonance imaging (rs-fMRI) or functional near-infrared spectroscopy (fNIRS) will be measures for tracking changes in abnormal brain regions/networks.
Correlations between swallowing recovery and brain function changes, plus group imaging differences, will reveal tDCS's neurophysiological mechanism.

Detailed Description:
This study aims to verify the efficacy of tDCS in treating dysphagia in PD and explore its mechanism. Subjects are randomly divided into two groups: the control group receives sham tDCS as well as the conventional dysphagia treatment, while the experimental group undergoes real tDCS combined with conventional dysphagia treatment.
All subjects will be evaluated before treatment, after treatment, and 3 months later (follow-up). Swallowing function in both groups will be assessed using the gold standard VFSS and swallowing scales. Additionally, techniques including amplitude of low frequency fluctuation (ALFF) and functional connectivity (FC) in rs-fMRI or fNIRS will be used to observe changes in abnormal brain regions and brain network connectivity before and after treatment in both groups.
This study will also explore the correlation between swallowing function recovery and the alteration of brain function, compare the imaging differences between the two groups, and thereby reveal the neurophysiological mechanism underlying tDCS in the treatment of PD-related dysphagia.
