CONCLUSION: the motor cortical excitability is increased in PD patients. The excitability is higher with the more serious symptom side.

结论：PD患者的运动皮质兴奋性增高，且与症状严重程度相关。

TDCS can lead to reversible shifts in cortical excitability and has the potential to interfere in these abnormal pathophysiological processes.

TDCS能在大脑皮层产生可逆性的兴奋并且有具有干涉异常的病理生理过程的潜能。
