How Does Deep Brain Stimulation Work?

Deep Brain Stimulation

Deep brain stimulation (DBS) is a neurosurgical operation that employs electrical stimulation and implanted electrodes to treat movement disorders such as Parkinson’s disease (PD), essential tremor, dystonia, and other neurological illnesses. When medicines are no longer effective or their negative effects interfere with a person’s everyday activities, doctors may utilize DBS to treat movement disorders or neuropsychiatric diseases.

How does it work?

Disorganized electrical signals in the parts of the brain that govern movement generate movement-related symptoms in Parkinson’s disease and other neurological diseases. DBS blocks the erratic signals that produce tremors and other movement disorders when it is effective. Neurosurgeons implant one or more cables called “leads” inside the brain after a battery of tests to find the best location. The leads are connected to a very small neurostimulator (electrical generator) placed beneath the person’s collarbone, similar to a heart pacemaker, by an insulated wire extension.

The neurostimulator transmits constant pulses of electric current through the leads and into the brain.

The doctor programs the neurostimulator to deliver an electrical signal a few weeks after it is implanted. This programming process could take several visits over several weeks or months to guarantee that the current is appropriately adjusted and giving effective results. The clinician finds an appropriate balance between increasing symptom control and limiting negative effects when changing the equipment.

DBS is often beneficial to three categories of PD patients:

  • Patients with excessive tremors who have failed to respond to medicines.
  • Patients with movement symptoms may benefit from greater or more frequent treatment doses but are unable to do so due to side effects.
  • Patients with symptoms that respond well to treatment but who, despite medication changes, endure severe motor fluctuations and dyskinesias when the meds wear off.

Essential Tremor – Essential tremor is the most prevalent movement disorder, and DBS can be a useful treatment, especially in severe cases where the trembling is incapacitating, affecting daily activities like dressing, shaving, eating, and drinking. Because tremor is the only symptom of essential tremor, DBS can help persons with the illness live more comfortably and perform effectively.

Dystonia – Dystonia is a very uncommon movement disease, but its symptoms — aberrant postures and twisting movements — sometimes respond to DBS when other treatments fail. The underlying etiology of dystonia – genetic, drug-induced, or other — determines an individual’s response to DBS. If the cause is unknown, the doctor will likely do more testing as part of the DBS evaluation.

Psychiatric Conditions – People suffering from depression, obsessive-compulsive disorder (OCD), or Tourette disorder may benefit from DBS surgery, according to several recent research. More research is needed to see if DBS is useful in treating psychiatric problems and if the risks and side effects outweigh the benefits.

Note:- As soon as one gets to know that they have Parkinson’s disease, the person can begin thinking about DBS. DBS is surely advantageous in the future even if now not ready to go.

Best destination or hospital for DBS surgery:-

Indian healthcare personnel has experience working worldwide and possess the essential abilities to perform successful deep brain stimulation surgery. The doctor’s degree of expertise is exceptional and deserves praise. The post-operative care and therapy that the patients receive are simply exceptional.

This is why only a highly skilled and experienced surgeon should do this procedure. India is known for producing a big number of highly proficient brain surgeons who have studied at some of the world’s top medical schools. When compared to other western countries, deep brain stimulation treatment in India is more reasonable.

If we talk about the cost, deep brain stimulation surgery cost totally depends upon the medical or the condition of the patient, tools, number of days stay in the hospital, medication, and the device used during the surgery.


As you’ll be in a completely different country and culture, traveling abroad for medical treatment may be an unusual experience, full of unexpected and unplanned incidents. This is something that MEdigence destination guides can help you with. But apart from that, Medigence’s HIPPA-compliant server makes it an excellent platform for conducting confidential consultations about patients’ medical records. Only the patients have access to this platform, which keeps all of the vital information about the patients safe and protected.
