Preoperative Instructions: Instructions such as fasting or stopping some medications before surgery.
Aftercare Arrangements: Plan for follow-up care for programming the device and the recovery process.
Support System: Engage the people around you for emotional support while recovering.
Preparing Mentally and Emotionally: Use relaxation techniques and make an appointment with a counsellor if you are able in order to prepare emotionally.
Follow Instructions: Follow all instructions from your medical team before, during and after the procedure.

Procedure for Deep Brain Stimulation (DBS)

Deep Brain Stimulation (DBS) is a surgical procedure that involves the implantation of a medical device, commonly referred to as a neurostimulator or brain pacemaker, to alleviate the symptoms of various neurological disorders. This procedure requires a skilled surgical team and careful postoperative management. Here is an overview of the DBS procedure:

Pre-Surgery Evaluation:

Thorough review of the patient’s previous medical history

Brain imaging (MRI or CT scan) for target area identification

Please note we can only process inquiries for England and Scotland.

Anesthesia:

It is performed under local anesthetic or so-called light sedation

Patient can sometimes stay awake during parts of the procedure for accurate placement of electrodes

Electrode Implantation:

A small hole is drilled in the skull

Thin electrodes are precisely implanted in a specific target of the brain

Pulse Generator Implantation:

A small pulse generator (similar to a pacemaker) is implanted under the skin, usually near the collarbone or in the abdomen

Those electrodes in the brain are connected to the pulse generator.

Testing and Adjustment:

The system is then tested to verify the placement of the electrodes

The pulse generator is tuned to provide the appropriate electrical impulses

Post-Surgery Adjustments:

Device programming occurs initially

Ongoing in-clinic visits for device adjustments (settings, etc.)

After Surgery Care

Hospital Stay: The patient is usually monitored in the hospital for a brief period following the surgery to ensure no immediate complications.
Programming: After a few weeks of healing, the neurostimulator is programmed by a neurologist to deliver the appropriate electrical stimulation settings for symptom control. These settings can be adjusted over time to optimize the therapeutic effect.
Follow-Up: Regular follow-up appointments are scheduled to assess the patient’s progress, adjust stimulation settings, and address concerns.
Lifestyle Adjustments: Patients are provided with guidelines for daily activities, including care for the implanted device and managing any potential interactions with other electronic devices.

Risks and Complications

Surgical risks include infection, bleeding, and adverse reactions to anesthesia.
Neurological complications, like stroke, seizure, or cognitive changes.
Hardware-related issues, including device malfunction, electrode displacement, or lead breakage.
Changes in mood, behavior, or personality due to the brain’s altered electrical activity.
Individual outcomes vary, and not all patients experience significant symptom improvement.

Recovery after Deep Brain Stimulation

Recovery after deep brain stimulation (DBS) is a crucial phase in the treatment process. DBS is a medical procedure involving the implantation of electrodes into specific brain regions to treat various neurological conditions, such as Parkinson’s disease, essential tremors, and dystonia. The recovery process can vary depending on the condition being treated, the individual’s overall health and the surgical approach used.
