Q: What is Parkinson's disease?
A: Parkinson's disease is a progressive disorder that affects the part of the brain responsible for movement, also known as the basal ganglia. It is most commonly known to cause a tremor (shaking or trembling) of the hands, but can also affect walking and initiation of movements. It can cause other symptoms such as problems with sleep and mood changes.
Q: Can you explain how DBS works and how it helps Parkinson’s patients?
A: Deep brain stimulation (DBS) is brain surgery which involves precisely inserting an electrode into each side of the basal ganglia deep in the part of the brain that controls movement. Each electrode is fixed to the skull and connected to a pacemaker implanted in the chest. DBS delivers electrical signals that neuromodulate the motor circuitry to improve the signs and movement symptoms of Parkinson's, such as stiffness and slowness. It reduces the fluctuations in movements despite medications and restores quality of life. It also improves dystonia and tremor.
Q: What is the most rewarding part of performing DBS surgery for Parkinson’s patients?
A: DBS is a highly technical operation. Patients are put to sleep, and I’m able to use a minimally invasive technique, with minimal hair removal, to complete a quick operation. The surgery is technically challenging. Getting an accurate result of electrodes placed within 1mm of their intended target is key. The most satisfying part of my job is seeing the improved symptoms after the patient wakes, their gratitude and later hearing about the activities they have been able to return to.
Q: How effective is the treatment?
A: Movement disorders can be debilitating, impacting every aspect of daily life. At The London Clinic, we are proud to offer innovative deep brain stimulation therapy—an advanced treatment backed by scientific research and delivered by leading experts.
The safety and effectiveness of deep brain stimulation have been well established in treating Parkinson’s disease, tremor, and dystonia. Research has shown that this therapy can improve symptoms by over 50% in individuals with dystonia, with benefits continuing to increase over time. For those with Parkinson’s disease, deep brain stimulation can also reduce medication dependence and improve tolerance.
Q: What advice would you give to someone recently diagnosed with Parkinson’s who is considering surgical options?
A: Ask your doctor about DBS. If you have had symptoms for at least a couple of years despite medication, then it may improve these symptoms and your quality of life. In the UK there is a huge unmet need for DBS compared to the prevalence of Parkinson's disease, which is one of the most common neurological disorders. If someone says you are not a candidate for the surgery find out why and seek second opinions.
