Transcranial Direct Current Stimulation for Treating Parkinson´s Disease-related Pain in OFF State

Brief summary (registry, in English)

Parkinson's Disease (PD) is a neurodegenerative disorder characterized by motor and non-motor symptoms. Pain is a significant symptom in PD, affecting a large percentage of patients and impacting their quality of life. The mechanisms of pain in PD involve complex changes in pain-modulating pathways, including dopaminergic and non-dopaminergic systems. To address the lack of pain management strategies, the investigators propose exploring non-pharmacological therapies like transcranial direct current stimulation (tDCS). tDCS is a safe and non-invasive technique that modulates neuronal activity. It has shown positive effects on pain processing in healthy individuals and chronic pain patients, but its potential for PD-associated pain remains largely unexplored. The primary motor cortex (M1) is a target for tDCS as it is believed to influence pain processing in other brain regions involved in sensory and emotional aspects. Initial studies suggest the benefits of tDCS in PD, including enhanced motor potentials and potential modulation of dopaminergic pathways. However, there are currently no published studies specifically investigating the effects of tDCS on PD-related pain, highlighting the need for further research. A proof-of-concept trial is proposed to examine the effects of a single tDCS session on M1 in PD patients during the OFF state (without medication) and after taking dopaminergic medication. The study aims to assess the pain-relieving effects of tDCS in PD and explore potential synergies between tDCS and dopaminergic medication. By better understanding the impact of tDCS on pain relief in PD, this research may offer insights into alternative non-pharmacological approaches for managing pain in PD.
