Is CyberKnife Treatment for Parkinson's Disease Reliable?
At present, no technological intervention can completely cure Parkinson's disease, and CyberKnife therapy can only partially alleviate symptoms. Also known as neuroablation, this procedure involves destroying overactive neural clusters in the brain's basal ganglia. While its effectiveness has been widely recognized, it is considered a destructive surgical method. Once the nerves are damaged, the effects are irreversible, and some patients report unsatisfactory long-term outcomes.
Understanding the Risks of Neuroablation
Approximately 4% of patients undergoing this procedure experience complications such as intracranial hemorrhage or targeting errors. Moreover, the surgery typically can only be performed on one side of the brain, meaning it can only manage symptoms on one side of the body. Performing bilateral ablation simultaneously is generally avoided due to the risk of severe complications. Even when staged separately, the complication rate remains as high as 30%.
Potential Side Effects of Bilateral Ablation
Patients who undergo bilateral neuroablation may experience symptoms such as reduced voice volume, difficulty swallowing, drooling, fatigue, and balance issues. Due to these risks and the irreversible nature of the procedure, it has become less common in Western medical practices.
A Shift Toward Brain Pacemaker Surgery
Brain pacemaker surgery, also known as deep brain stimulation (DBS), has increasingly replaced neuroablation. This method offers a reversible and adjustable form of neuromodulation. Unlike ablation, DBS does not destroy brain tissue and allows for external adjustments to stimulation settings, giving patients multiple programmable options.
Advantages of Deep Brain Stimulation
DBS provides several benefits, including minimal invasiveness, the ability to charge the device, and the flexibility to adapt to future treatment advancements. It also avoids the irreversible damage associated with traditional neuroablation techniques, making it a safer and more adaptable long-term solution for managing Parkinson's symptoms.
