Steps In The Deep Brain Stimulation (DBS) Procedure
- Consultation with our doctors at Aster.
- If Deep Brain Stimulation (DBS) is a treatment option for you, extended examinations are conducted
- Once it has been established that there are no contraindications, and you have provided consent, we can proceed to the admission for the surgery.
- Pre—operative management of medication and preparation are conducted.
- Surgery is performed, and patients are usually kept awake with light sedation, to better test brain functions, effects and side effects.
- Patients are then introduced to the Deep Brain Stimulation (DBS) neurostimulator, it‘s programming, and functional testing
- Transfer to a rehabilitation clinic, if required.
- Regular aftercare for outpatients (at least once a year) and follow-up care for inpatients, if needed.
Can I Wait For Some Time Before Considering Deep Brain Stimulation (DBS)?
There is a window of opportunity where Deep Brain Stimulation (DBS) is helpful for you. Deep Brain Stimulation (DBS) Therapy is no longer an option when:
- Medications stop improving your symptoms
- There is severe disability.
- Surgery is not advisable for any other contraindication
Think Earlier – A lot of people assume that Deep Brain Stimulation (DBS) Therapy is a last-ditch effort to preserve your way of life. This however is not true, and Deep Brain Stimulation (DBS) should be considered and evaluated when your medications are becoming less effective at controlling your movements. Speaking with a Deep Brain Stimulation (DBS) expert can help you find the right answers - it's never too early to talk with your doctor about Deep Brain Stimulation (DBS), and it's important not to wait too long.
What Are the Risk? Safety Profile Of Deep Brain Stimulation (DBS) Therapy?
Deep Brain Stimulation (DBS) has been in use for nearly 30 years. Any possible risks and complications are well known and can be easily predicted. It is a relatively safer procedure with minimal risk.
Our Deep Brain Stimulation (DBS) Speciality Clinic at the hospital can provide you with the detailed information on potential complications and risks involved in the procedure.
Are the benefits of DBS predictable?
A. Individual patient outcomes depend on several factors, including age, proper patient selection, target selection and accuracy of final electrode location, programming settings, adjustments in medicines following DBS.
B. Symptoms of PD that improve with levodopa, improve after DBS. The only exception is tremor which will subside after DBS, even if it is not relieved by levodopa.
C. Partial or incomplete response to DBS in PD patients may be partly due to incorrect patient selection (patients not having PD but other diseases resembling PD) or suboptimal DBS electrode placement.
D. Unrealistic expectations from DBS can also result in patients being dissatisfied with the treatment.
E. A critical factor influencing successful outcomes for DBS is a multidisciplinary team that specializes in the care of patients with DBS devices. The typical team includes a movement disorder specialist, a neurosurgeon who has a specialty training in stereotactic and functional neurosurgery and a neuropsychologist who has knowledge and experience assessing cognitive, mood and behavioural changes in PD. Patient outcomes are better when DBS surgeries are performed regularly by the team in high volume centres.
F. Device programming and management of medications following DBS should ideally be provided by an experienced movement disorder specialist.
What is the role of DBS in Parkinson's Disease?
- Experiencing fluctuations in response to levodopa with or without dyskinesias
- Tremor which is not relieved by levodopa
- Who cannot tolerate high doses of drugs. Recent studies have shown that patients with mild to moderate fluctuations or dyskinesias with levodopa treatment benefit as much as those with more advanced disease. Therefore early referral is indicated before patients experience any disability due to these phenomena.
- Long-term results of DBS have shown significant improvement in the motor symptoms of PD and the fluctuations in response to treatment. As patients require less medications after DBS, they also have much reduction in the dyskinesias. Majority of patients regain the the ability to perform activities of daily living independently and the quality of life of patients improves
How does deep brain stimulation work?
The accuracy of placement is confirmed prior to implantation of the DBS electrode by the movement disorder specialist, first, by recording characteristic firing patterns of brain cells in the target area using a procedure called microelectrode recording. This is followed by a test electrical stimulation to assess the benefits or any unwanted effects of stimulation in that location. Once the location is confirmed, the DBS electrode is implanted in that spot. In the days to weeks following DBS surgery, the movement disorder specialist will select the appropriate current settings in the implanted IPG that will provide the best clinical benefits to the patient using a remote controller-like device. This procedure is called programming. It may need a few programming sessions in the first 3-6 months to identify the best stimulation settings for an individual. Thereafter, clinic visits can be annual, to check battery settings, battery life and for adjustment of drugs.
How long does deep brain stimulation last?
A well-done deep brain stimulation can help patients for as long as 15 years with an improved quality of life.
Are You A Candidate For Deep Brain Stimulation (DBS)?
A lot of research has gone into finding the a suitable patient for Deep Brain Stimulation (DBS). Preliminary screening can be done by answering following four questions to see if Deep Brain Stimulation (DBS) therapy may be useful for you.
- Are your medicines not able to control your symptoms completely throughout the day – Yes/No
- Is troubling dyskinesias (involuntary excessive movements) becoming a problem for you? – Yes/No
- Has your frequency and dosage of DA drugs increased in the last few months? – Yes/No
- Are drug combinations causing side effects such as: sleepiness, nausea, hallucinations, confusion/other thinking problems, lightheadedness upon standing, behavioral/personality changes? – Yes/No
"Yes" to some of the questions above provides you a guidance and you should further ask your doctor if Deep Brain Stimulation (DBS) Therapy is right for you.

What Are The Benefits Of Deep Brain Stimulation (DBS) In Parkinson’s Disease?
The following are 6 major outcomes of the Deep Brain Stimulation (DBS) procedure:
- Reduces dyskinesia and fluctuations
- Up to 5 additional hours of good movement without dyskinesia
- Treats tremors and rigidity
- Improves activities of daily living
- Works day and night
- Improves quality of life.
Is the Deep Brain Stimulation (DBS) A Well Established form of Therapy ?
This therapy started developing in 1987 and is backed by decades of research, innovation, and experience. There is a lot of clinical evidence and it is supported by 5 Level 1 clinical studies—the highest quality of evidence. As of 2017, more than 150,000 people have received Deep Brain Stimulation (DBS) worldwide.
Which are the conditions treated by DBS?
DBS is a recommended treatment for Parkinson’s disease, Essential Tremor and Primary Generalized Dystonias. It has also shown success in some forms of secondary dystonias and Tourette syndrome. The most common condition for which DBS is used is Parkinson's disease (PD). DBS cannot cure any of these diseases but gives substantial relief from the abnormal movements and improves the quality of life of persons affected by these diseases.
When to get deep brain stimulation?
Deep brain stimulation is a major surgical procedure that requires the utmost care and expertise. In addition, it is required to get deep brain stimulation in case of debilitating conditions which cause motor problems like Parkinson's, inability to walk, the rigidity of movements, and slow movement of limbs to the extent of disturbing regular life.
Why is deep brain stimulation used?
Deep brain stimulation is now being used widely with excellent acceptance for patients with movement disorders like tremors, Parkinsonism, Parkinson's disease, dystonia(loss of muscle tone), psychiatric disorders like OCD(obsessive-compulsive disorder).
What is deep brain stimulation?
DBS involves delivering small amounts of electricity via 2 thin electrodes (one on each side of the brain) which are introduced through 2 small holes in the skull and implanted into specific target areas deep in the brain. This procedure called stereotactic neurosurgery, is different from usual neurosurgery. The source of the electric current delivered, is a sophisticated pacemaker-like device (implantable pulse generator or IPG) placed under the skin of the chest, below the collar bone. The IPG on the chest is connected to the two electrodes within the brain through extension cables passing under the skin of the neck, behind the ear. Several software packages are available to plan the placement of the electrode using the brain MRI of the person.
