Deciding whether to undergo brain surgery can be one of the most challenging decisions faced by individuals with Parkinson’s disease. This progressive disorder affects movement, causing tremors, muscle stiffness, slow movements, and balance issues—symptoms that tend to worsen over time, making daily tasks like walking, eating, or dressing increasingly difficult.
One treatment option that can provide relief for some patients is deep brain stimulation (DBS), a surgical procedure. During DBS, doctors implant a small device that sends electrical impulses to specific areas of the brain responsible for movement control. This device, powered by a battery, functions similarly to a cardiac pacemaker but for the brain.
While DBS can substantially reduce symptoms such as tremors, rigidity, and bradykinesia for certain individuals, it’s a complex procedure with potential risks, and not everyone is suitable for the surgery. The outcomes vary from person to person, making the decision to proceed an emotional and complicated process for patients and their loved ones.
Researchers at the University of Colorado Anschutz Medical Campus aimed to simplify this decision-making process. They developed the first evidence-based decision aid designed specifically to help people with Parkinson’s better understand DBS and evaluate if it’s right for them. Their work was detailed in the Journal of Parkinson’s Disease.
This tool is intended to inform rather than instruct. Its purpose is to provide patients with comprehensive knowledge about DBS, encouraging a shared decision-making approach, where patients and healthcare providers collaborate to determine the best treatment path. Dr. Michelle Fullard, who led the research and serves as Director of Clinical Research at CU Anschutz Movement Disorders Center, highlighted that the tool helps patients feel more prepared before discussing DBS with their doctors.
Many patients feel uncertain because they lack a clear understanding of how the surgery works or what kind of results to expect. The new decision aid offers straightforward information, empowering patients to participate more actively in their care and ask informed questions.
The development of this tool involved a meticulous scientific process. Researchers first solicited feedback from patients about the information they found missing when considering DBS. They then reviewed numerous scientific studies on the procedure. An initial version was created and tested in clinical settings, with ongoing improvements based on patient input.
Over 120 people with Parkinson’s participated in this development. Fifty-seven provided insights into their informational needs, 22 tested the initial version, and 46 helped evaluate the final version. When assessed, the tool showed very positive results; most users reported that it enhanced their understanding of DBS and increased their confidence in making decisions.
A key feature of the tool is a personalized symptom report. Patients can input their individual symptoms, and the system estimates how likely they are to see improvement after DBS. This helps manage expectations by illustrating what the surgery might realistically achieve and what it may not.
Dr. Fullard emphasized that some patients initially hope DBS will resolve all their issues, which can lead to disappointment if expectations aren’t met. The decision aid aims to set realistic perceptions from the start, providing a clear view of the potential benefits and limitations.
The study also uncovered notable differences between men and women contemplating DBS. Women were more likely to live alone and expressed more concern about post-surgical assistance, particularly for daily activities like meal preparation and household chores. This aligns with previous research indicating women often approach medical decisions differently than men. Despite similar rates of Parkinson’s among men and women, women are less frequently referred for DBS, a gap possibly influenced by disparities in support and informational needs.
The decision aid is currently being tested in a clinical trial to determine if it improves patient satisfaction and decision quality over the long term. It is freely available online, and many Parkinson’s organizations are distributing it within their communities. Healthcare providers are also encouraging patients to use the tool prior to consultations, so discussions are more productive.
Future plans include expanding this research across multiple clinics nationally and adapting the tool for other neurological treatments, such as essential tremor. This effort reflects a broader shift toward patient-centered healthcare, emphasizing education, shared decision-making, and personalized care.
While initial findings are promising, the researchers acknowledge that more studies are needed to assess whether the tool influences long-term health outcomes or quality of life after surgery. Nonetheless, this development suggests that well-designed educational resources can make complex treatment choices more understandable and less stressful—empowering patients with Parkinson’s to navigate one of their toughest medical decisions with greater confidence.
