Deep brain stimulation (DBS) for dystonia is a surgical treatment in which thin electrodes placed in the globus pallidus internus (GPi), or sometimes the subthalamic nucleus (STN), deliver continuous, adjustable electrical stimulation that calms the abnormal brain signals causing dystonic contractions. It is the most effective treatment for disabling dystonia that medicines and botulinum toxin no longer control.
Its effect is proven in sham-controlled randomized trials. In primary generalized and segmental dystonia, stimulation improved movement scores by 15.8 points against 1.4 points with sham;[1] in cervical dystonia, pooled data from 208 patients show a 58.8% average improvement;[2] in Meige syndrome, about 60% at one year;[3] and in tardive dystonia, 76%.[4] At Neuromodulation in Turkey, Prof. Atilla YILMAZ, MD and a dedicated 25-member DBS team have performed 1,200+ neuromodulation procedures, including 800+ DBS surgeries, for patients from 60+ countries.
How does DBS work in dystonia?
Dystonia is caused by abnormal, overly synchronized activity in the network that links the basal ganglia, thalamus, cerebellum and motor cortex. The globus pallidus internus is a key output station of this network. High-frequency stimulation there disrupts the abnormal pattern, so the muscles stop receiving the faulty “pull” signal. Nothing is removed or destroyed; the stimulation is reversible and can be adjusted at any time.
A DBS system has three parts:
- Two electrodes (leads), one on each side of the brain, usually in the GPi
- Extension wires running under the skin behind the ear and down the neck
- A pulse generator, a small battery-powered device under the skin below the collarbone, programmed wirelessly
Who can benefit from DBS for dystonia?
DBS is considered when dystonia is disabling and adequate trials of medication and, for focal forms, botulinum toxin have not given enough relief. The best results are seen in:
- Generalized and segmental isolated dystonia, especially DYT1 (TOR1A)
- Cervical dystonia not controlled by injections
- Meige syndrome (orofacial and cranial dystonia)
- Tardive dystonia and tardive dyskinesia
- Myoclonus-dystonia (DYT11, SGCE)
Acquired dystonia from brain damage, such as dyskinetic cerebral palsy, responds less, and the decision is made individually. See am I a candidate for DBS?
GPi or STN: which target is used for dystonia?
The globus pallidus internus (GPi) is the most studied target and was used in the landmark randomized trials in generalized, segmental and cervical dystonia.[1][5] The subthalamic nucleus (STN) is an alternative with similar results in cervical dystonia and Meige syndrome in the published data.[6][3] STN stimulation needed less electrical energy in the Meige trial, while GPi has the longest track record. Prof. YILMAZ chooses the target for each patient according to the type of dystonia, accompanying symptoms such as tremor, and the patient’s anatomy.
How successful is DBS for dystonia?
Average improvement in published studies.[4][7][3][2][8][9] Rating scales and follow-up differ between studies. Literature data, not our own case series; individual results vary. Full detail on DBS for dystonia success rates.
How quickly does DBS work in dystonia?
Dystonia improves more slowly after DBS than tremor or Parkinson’s disease. Quick, jerky (phasic) movements and tremor often settle within days to weeks. Fixed (tonic) postures loosen gradually over months as the muscles and the brain network adapt. Most of the benefit is usually reached within 6 to 12 months, and in the long-term trials it was maintained at 3 and 5 years.[10][11] Patience during the first months is part of the treatment.
What are the risks of DBS for dystonia?
- Surgical risks: bleeding in the brain and infection are the most important; both are uncommon. In our own case series the infection rate is 1.6%.
- Stimulation side effects: for example slurred speech, muscle pulling or slowness of movement. These are usually reversible by changing the settings.
- Hardware issues: lead or wire problems and battery replacement for non-rechargeable devices. Dystonia usually needs more energy than Parkinson’s disease, so rechargeable stimulators are often preferred.
Your personal risk is discussed in detail during the evaluation. See DBS surgery and recovery.
Why patients choose Neuromodulation in Turkey for dystonia DBS
- A surgeon who trains other surgeons. Prof. YILMAZ holds official proctorship agreements with Medtronic, Abbott and Boston Scientific — the world's three leading manufacturers of DBS systems appoint him to train other neurosurgeons on their technology.
- Our results. In our own case series, patients treated with DBS for cervical dystonia, Meige syndrome and myoclonus-dystonia have shown more than 90% improvement in their symptoms, based on clinical assessment and documented on video. Individual results vary.
- Experience. 1,200+ neuromodulation procedures, including 800+ DBS surgeries, for patients from 60+ countries. Prof. YILMAZ has trained 40+ neurosurgical fellows and observers from 30 countries.
- A dedicated DBS team of 25 people, including neurologists, psychiatrists, psychologists, physiotherapists, DBS nurses and interpreters.
- The latest technology. Prof. YILMAZ was the first surgeon in Turkey to use the Abbott Liberta RC™ system with NeuroSphere™ Virtual Clinic remote programming and the Medtronic Percept™ BrainSense™ adaptive DBS technology. All planning uses 3 Tesla MRI. See what makes DBS for dystonia successful.
- Remote programming by video call for compatible systems, so international patients can have their settings adjusted from home.
- A transparent package price: An all-inclusive DBS package at our center typically ranges between USD 30,000 and USD 45,000, depending on the package and the type of device selected. The final figure is confirmed after your evaluation. See international patients.
Frequently asked questions
Is DBS a cure for dystonia?
No. DBS controls the symptoms but does not remove the cause. The benefit continues as long as stimulation continues, and it has been shown to last for years.[11]
Is DBS for dystonia safe?
DBS is an established operation performed for more than two decades. Serious complications are uncommon, and stimulation side effects can usually be reversed by reprogramming. In our own case series the infection rate is 1.6%.
Am I awake during DBS surgery for dystonia?
At our center DBS for dystonia is performed under general anesthesia, with MRI-based planning and intraoperative imaging to confirm electrode position.
How long does a DBS battery last in dystonia?
Dystonia uses more energy than many other indications, so non-rechargeable batteries may need replacement after a few years. Rechargeable systems can last much longer. The choice is discussed before surgery.
Can DBS be done if botulinum toxin still works partly?
Yes. DBS is considered when the overall control is not good enough, not only when injections fail completely. Many patients need fewer or no injections after DBS.
How much does DBS for dystonia cost?
An all-inclusive DBS package at our center typically ranges between USD 30,000 and USD 45,000, depending on the package and the type of device selected. The final figure is confirmed after your evaluation.
