What Is Deep Brain Stimulation?

Deep Brain Stimulation (DBS) is a groundbreaking neurosurgical procedure used to treat a variety of neurological and psychiatric disorders. Often referred to as a “brain pacemaker,” DBS involves implanting electrodes into specific areas of the brain to deliver electrical impulses that regulate abnormal brain activity.

Originally developed to treat movement disorders like Parkinson’s disease, DBS has expanded its scope over the years and is now being explored for conditions such as epilepsy, obsessive-compulsive disorder (OCD), depression, and even Alzheimer’s disease.

In this comprehensive guide, we will explore everything you need to know about deep brain stimulation — from how it works and who can benefit from it, to the latest advancements in the field and the growing prominence of DBS treatment in Turkey.

How Does Deep Brain Stimulation Work?

(DSB)  works by modulating the electrical activity in targeted areas of the brain. The procedure involves three main components:

1. Electrodes (leads) – Thin wires implanted into specific brain regions.
2. Extension wire – A connecting wire that runs under the skin from the head to the chest or abdomen.
3. Implantable Pulse Generator (IPG) – A battery-powered device, similar to a heart pacemaker, placed under the skin in the chest or abdomen. It sends continuous electrical pulses to the brain.

The Brain Regions Targeted by DBS

Depending on the condition being treated, different areas of the brain are targeted:

• Subthalamic Nucleus (STN) – Most commonly used for Parkinson’s disease.
• Globus Pallidus Internus (GPi) – Used for Parkinson’s disease and dystonia.
• Ventral Intermediate Nucleus (Vim) – Used for essential tremor.
• Anterior Limb of the Internal Capsule (ALIC) – Used for OCD and depression.

These areas are responsible for movement control, mood regulation, and other neurological functions. By stimulating these regions, DBS can help reduce symptoms and improve quality of life.

Who Is a Candidate for Deep Brain Stimulation?

DBS is typically recommended for patients who:

• Have been diagnosed with a neurological disorder that does not respond well to medication.
• Experience significant side effects from medication.
• Are in overall good health and can tolerate brain surgery.

Approved Conditions for DBS

Currently, DBS is FDA-approved for the following conditions:

1. Parkinson’s Disease
2. Essential Tremor
3. Dystonia
4. Epilepsy (certain focal epilepsy cases)
5. Obsessive-Compulsive Disorder (OCD)

Research is ongoing into its effectiveness for treating depression, Tourette syndrome, chronic pain, and Alzheimer’s disease.

The Deep Brain Stimulation Procedure: Step-by-Step

1. Pre-Surgical Evaluation

Before undergoing DBS surgery, patients undergo a thorough evaluation that includes:

• Neurological exams
• Psychological assessments
• MRI or CT scans to map the brain
• Trial of medication to assess responsiveness

2. Surgical Implantation

The DBS procedure is typically done in two stages:

Stage 1: Electrode Placement

• Performed under local anesthesia (the patient is awake to help guide electrode placement).
• Using stereotactic techniques, the surgeon implants electrodes in the targeted brain area.
• Microelectrode recording may be used to confirm the correct placement.

Stage 2: Implantation of the Pulse Generator

• Done under general anesthesia.
• The IPG (battery) is implanted under the skin in the chest or abdomen.
• Wires from the brain electrodes are tunneled under the skin and connected to the IPG.

3. Post-Surgery Programming and Adjustment

• The IPG is activated a few weeks after surgery.
• Regular follow-ups are needed to adjust the stimulation settings for optimal symptom control.
• Programming is done using an external device and may take several sessions over weeks or months.

Benefits of Deep Brain Stimulation

DBS offers a range of benefits for patients with neurological disorders:

• Symptom Reduction: Tremors, rigidity, and dyskinesia (involuntary movements) are significantly reduced in Parkinson’s patients.
• Improved Quality of Life: Patients often experience greater independence and ability to perform daily tasks.
• Reduced Medication Dependence: Many patients can lower their medication dosage after DBS, reducing side effects.
• Reversible and Adjustable: Unlike older lesioning surgeries, DBS is reversible and the stimulation can be adjusted as needed.

Risks and Complications of DBS

Like any surgical procedure, DBS carries some risks, including:

• Surgical Risks: Infection, bleeding in the brain, and seizures.
• Hardware Complications: Lead migration, device malfunction, or erosion of the skin over the IPG.
• Side Effects of Stimulation: Mood changes, speech difficulties, tingling sensations, or balance issues.

However, with advancements in surgical techniques and careful patient selection, complications are relatively rare and often manageable.
