Professor Zhang Jianguo: Deep Brain Stimulation and Neuromodulation Specialist
Professor Zhang Jianguo is a senior neurosurgeon, professor, doctoral supervisor, deputy director of the Neurosurgery Center and director of Functional Neurosurgery at Beijing Tiantan Hospital. His clinical and academic work focuses on deep brain stimulation, Parkinson’s disease, dystonia, essential tremor, Tourette syndrome, drug-resistant epilepsy, trigeminal neuralgia, hemifacial spasm, and advanced neuromodulation.
Clinical and Academic Focus
- deep brain stimulation for Parkinson’s disease;
- dystonia and essential tremor;
- Tourette syndrome and other movement disorders;
- drug-resistant epilepsy surgery;
- trigeminal neuralgia and hemifacial spasm;
- implantable neuromodulation devices;
- postoperative programming and remote follow-up;
- revision of ineffective or complicated DBS; and
- second opinions before functional neurosurgery.
Deep Brain Stimulation
Deep brain stimulation, or DBS, uses implanted electrodes to deliver adjustable electrical stimulation to specific brain targets. It does not cure Parkinson’s disease, but it can improve selected medication-responsive motor symptoms, reduce fluctuations and dyskinesia, and sometimes lower medication burden.
Professor Zhang led clinical development and adoption of domestically manufactured DBS systems in China and has extensive experience with implantation and long-term programming.
DBS for Parkinson’s Disease
Potential candidates usually have a confirmed diagnosis, meaningful response to levodopa, disabling motor fluctuations, tremor, or dyskinesia despite optimized medication, and acceptable cognitive and psychiatric status.
Target selection may include the subthalamic nucleus or globus pallidus internus. The choice depends on symptoms, medication goals, cognition, mood, speech, gait, age, and the team’s assessment.
DBS generally provides less reliable benefit for medication-unresponsive balance, freezing, speech, or cognitive symptoms. Careful expectations are essential.
Dystonia and Essential Tremor
DBS may be considered for severe dystonia that remains disabling despite medication and other treatment. Response varies with the dystonia type, genetic cause, duration, skeletal deformity, and target.
For medication-refractory essential tremor, DBS can reduce limb tremor and improve function. Alternatives may include focused ultrasound or other lesion-based procedures in selected patients.
Tourette Syndrome
DBS for Tourette syndrome is reserved for a small group with severe, persistent, treatment-refractory tics after comprehensive neurological and psychiatric assessment. Target selection and expected benefit remain individualized.
Drug-Resistant Epilepsy
Epilepsy is considered drug-resistant when appropriate antiseizure medicines fail to achieve sustained seizure freedom. Evaluation may include prolonged video EEG, epilepsy-protocol MRI, PET, neuropsychology, and invasive monitoring.
Treatment can involve removal or disconnection of the seizure source, laser or radiofrequency ablation in selected cases, vagus-nerve stimulation, DBS, responsive stimulation where available, or dietary and medication strategies.
Trigeminal Neuralgia and Hemifacial Spasm
Microvascular decompression can provide durable relief when a blood vessel compresses the trigeminal or facial nerve. Other options include medication, percutaneous procedures, botulinum toxin for hemifacial spasm, or radiosurgery depending on diagnosis and health.
DBS Programming and Remote Care
DBS treatment continues after surgery. Programming adjusts contacts, amplitude, pulse width, frequency, and medication to balance symptom control with side effects.
Professor Zhang has contributed to Chinese guidance on remote DBS programming. Remote care requires a compatible approved device, secure platform, trained team, patient consent, and a clear plan for urgent local support.
Who May Consider a Consultation?
- patients with Parkinson’s disease and disabling motor fluctuations or tremor;
- patients with severe medication-refractory dystonia or essential tremor;
- patients considering DBS and needing multidisciplinary selection;
- patients with poor benefit or side effects after DBS;
- patients needing programming or device revision review;
- patients with drug-resistant focal epilepsy;
- patients with trigeminal neuralgia or hemifacial spasm; or
- patients seeking a second opinion before functional neurosurgery.
Medical Records to Prepare
- a concise symptom and treatment timeline;
- movement-disorder diagnosis and medication-response records;
- videos showing symptoms in medication-on and medication-off states when safe;
- brain MRI and CT in original DICOM format;
- neuropsychological and psychiatric assessments;
- DBS operative notes, lead location imaging, device model, and programming history;
- seizure diary, video EEG, epilepsy MRI, PET, and previous monitoring reports;
- complete medication history with response and side effects;
- cardiac, anesthesia, and other preoperative assessments; and
- a clear list of functional goals and questions.
Planning an International Consultation
A prolonged seizure, sudden severe weakness, confusion, suspected device infection, exposed hardware, or abrupt loss of stimulation with serious symptoms requires urgent local assessment.
Stable patients should confirm whether imaging, DBS device data, or epilepsy studies can be reviewed. Remote medical-record review or programming requires physician and device authorization. Final surgical eligibility usually requires in-person multidisciplinary evaluation.
How CMCS Can Assist
CMCS – China Medical Concierge Shanghai is an independent medical concierge and health management company, not a hospital. We assist international patients with organizing and translating neurological records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.
Access to Professor Zhang, remote review, DBS, programming, epilepsy surgery, or a specific device is subject to doctor and hospital approval. CMCS does not guarantee appointments, surgical eligibility, device compatibility, or clinical outcomes.
