Core Viewpoint - The introduction of the "brain-machine interface" deep brain stimulator represents a significant advancement in the treatment of Parkinson's disease, allowing patients to manage symptoms more effectively and improve their quality of life [1][2]. Group 1: Treatment Overview - Parkinson's disease is a degenerative neurological condition primarily affecting the elderly, with approximately 5 million patients in China, the highest number globally [1]. - Traditional treatment methods include medication, deep brain stimulation surgery, and rehabilitation, with deep brain stimulation recognized as the preferred surgical option [1]. - The newly developed "brain-machine interface" deep brain stimulator is rechargeable and capable of sensing, marking a technological leap in treatment [1][2]. Group 2: Technological Advancements - The new deep brain stimulator incorporates a small computer that reads and analyzes brain signals related to the disease, allowing for dynamic parameter adjustments without the need for frequent hospital visits [2]. - This technology enables a closed-loop treatment system, enhancing patient comfort and reducing the need for manual parameter adjustments that were previously required at set intervals [2]. Group 3: Patient Experiences - Patients like Mr. Xiao, who suffered from Parkinson's for over 15 years, report significant improvements in their symptoms and overall quality of life following the surgery [2]. - Mr. Wang, another patient, expressed gratitude for the advanced technology, highlighting the positive impact on his condition and emotional well-being [2].
