What is Deep Brain Stimulation (DBS)?

Deep Brain Stimulation (DBS) is a surgical procedure that involves implanting a device to send electrical signals to specific brain areas. It is used to treat movement and neurological disorders, offering symptom relief and improving the quality of life for many patients.

Conditions Treated with DBS

  • DBS is an effective treatment for:

    • Parkinson’s Disease: Reduces tremors, stiffness, and motor symptoms.
    • Dystonia: Alleviates involuntary muscle contractions.
    • Essential Tremor: Controls severe tremors affecting daily tasks.
    • Epilepsy: Reduces the frequency and severity of seizures.
    • Obsessive-Compulsive Disorder (OCD): Helps manage severe symptoms when other treatments fail.

How Does DBS Work?

  1. Electrode Placement:
    Electrodes are implanted in targeted brain regions based on the condition being treated.

  2. Pulse Generator Implantation:
    A small device, similar to a pacemaker, is implanted in the chest or abdomen to deliver electrical signals.

  3. Programming the Device:
    Doctors adjust the settings to optimize symptom relief without side effects.

  4. Continuous Stimulation:
    Electrical impulses modulate abnormal brain activity, improving symptoms.

Benefits of Deep Brain Stimulation

  • Non-Destructive: Unlike other surgical options, DBS doesn’t damage brain tissue.
  • Customizable: Stimulation can be adjusted as symptoms evolve.
  • Improved Quality of Life: Enables patients to regain independence and reduce medication use.

Risks and Considerations

While DBS is generally safe, potential risks include:

  • Surgical Risks: Infection, bleeding, or device malfunction.
  • Temporary Side Effects: Tingling, speech issues, or mood changes.
  • Adjustments Required: Device settings may need fine-tuning post-surgery.

What to Expect During DBS Surgery

  1. Pre-Surgical Assessment:
    Includes imaging scans (MRI, CT) and discussions with a neurologist and neurosurgeon.

  2. Surgery:
    Performed under local or general anesthesia, typically lasting 4–6 hours.

  3. Recovery:
    Most patients return to normal activities within a few weeks.

  4. Post-Surgery Programming:
    Device settings are fine-tuned over several visits to achieve the best results.

Who is a Candidate for DBS?

  • Individuals with severe symptoms unresponsive to medications.
  • Patients in good overall health and capable of undergoing surgery.
  • Those without cognitive impairments or severe psychiatric conditions.
