The goal of this clinical trial is to learn if Mindfulness-Enhanced Dual-Task Training work to treat PD-MCI in adults. The main questions it aims to answer are:

Does Mindfulness-Enhanced Dual-Task Training improve the cognitive or motor function of participants? Can the combination of Dual-Task Training and Mindfulness achieve better effects?

Researchers will compare 3 groups (Dual-Task Training + Mindfulness, Dual-Task Training, and conventional motor task training) to see if Dual-Task Training and Mindfulness works to treat PD-MCI.

Participants will:

Receive treatment for 4 weeks Receive scale and instrument testing before and after treatment
