AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with Parkinson's disease who have swallowing problems. It tests brain stimulation (tDCS) together with usual swallowing treatment.

Age
18 to 100 years
Sex
All sexes can join.
Disease stage
Parkinson's disease, or multiple system atrophy or progressive supranuclear palsy, with swallowing problems shown on a VFSS swallowing X-ray test.
Biomarker or test result
Mini-Mental State Examination (MMSE) score above 23.

Main reasons for not taking part

  • Another disease that causes swallowing problems
  • Pneumonia
  • Severe heart or kidney failure
  • Metal implants in the body
  • Memory or thinking problems, or unable to cooperate

Clinical Efficacy and Mechanism of tDCS for Dysphagia in Patients With Parkinson's Disease

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.

Inclusion: Meet the Chinese Diagnostic Criteria for Parkinson's Disease (2016) or MDS Diagnostic Criteria for Multiple System Atrophy or Progressive Supranuclear Palsy; VFSS examination indicates dysphagia; Mini-Mental State Examination (MMSE) score >23; Willing to cooperate with the study and sign the informed consent form.

Exclusion: Having metal implants in the body; Comorbid with other diseases that cause dysphagia; Comorbid with pneumonia, or severe cardiac/renal insufficiency; With cognitive impairment or inability to cooperate.
