The theme of the 2026 World Parkinson Congress was the Red Thread.
In Chinese and Japanese folklore, the Red Thread of Fate is an invisible string that connects people whose lives are meant to intersect. The thread may stretch or become tangled, but it can never be broken.
Parkinson's is not a thread anyone would choose. Yet it has a remarkable way of connecting people. At the World Parkinson Congress, neurologists, scientists, care partners, industry leaders, advocates, and people living with Parkinson's came together from around the world, all united by a common goal: to better understand, treat, and ultimately solve Parkinson's disease.
While we shared that common purpose, each person experienced the Congress through a different lens and walked away with something unique.
My experience was a little different. As a vendor and a person living with Parkinson's, I spent most of my time in the exhibit hall rather than attending the sessions. Instead of sitting in lecture rooms, I had the opportunity to do something equally valuable: talk with people.
So I started asking a simple question:
"What was your biggest takeaway from the World Parkinson Congress?"
The answers were as diverse as the people I met, but certain themes surfaced again and again.
Here's what I heard.
1. Parkinson's Is Not a One-Size-Fits-All Disease
One of the themes I heard repeatedly was that Parkinson's is far more complex than we once believed.
For years, Parkinson's was often viewed through a relatively simple lens. If you had a known genetic mutation, your disease was considered genetic. If not, it was labeled sporadic and thought to be driven by a combination of aging, environmental exposures, and factors we didn't fully understand.
Today, that picture is changing.
While the number of people diagnosed with Parkinson's continues to rise worldwide, researchers are increasingly recognizing that Parkinson's is not a single disease with a single cause. It is likely a collection of different biological pathways that can lead to similar symptoms.
Anyone living with Parkinson's can see this firsthand. No two people have the exact same experience. Symptoms vary. Progression varies. Responses to medications, exercise, and therapies vary.
Many attendees spoke about the importance of moving beyond a one-size-fits-all approach and toward personalized care. The goal is not simply to find one answer for everyone, but to better understand the unique factors driving each individual's disease.
The future of Parkinson's may not be one cure that works for all. It may be a combination of targeted treatments and interventions tailored to the person in front of us.
Another topic that came up repeatedly throughout the Congress was the possible role of environmental toxins in Parkinson's disease.
Much of this conversation has been driven by the work of Dr. Ray Dorsey and Dr. Michael Okun, neurologists and co-authors of The Parkinson's Plan. They have been outspoken advocates for investigating the environmental factors that may be contributing to the rise of Parkinson's worldwide.
Paraquat was frequently mentioned, but it is only one of several environmental exposures researchers are studying. Drs. Dorsey and Okun have also highlighted industrial solvents such as trichloroethylene (TCE) and perchloroethylene (PCE), along with other pesticides and pollutants that may increase Parkinson's risk. Growing concern about these chemicals is beginning to influence public policy. Earlier this year, Vermont became the first state to pass a ban on paraquat, reflecting increased awareness of the potential connection between environmental exposures and Parkinson's disease.
Researchers are also investigating Parkinson's hot spots, regions where rates of the disease appear to be unusually high. The goal is to better understand whether environmental exposures, agricultural practices, industrial pollutants, or other factors may help explain these clusters.
There is still much we do not know. However, this area of research continues to gain attention as scientists work to better understand what causes Parkinson's disease and whether some risk factors may be preventable. Understanding the causes of Parkinson's may ultimately prove just as important as developing new therapies to treat it.
3. Access to Care Is a Global Challenge
Perhaps the most sobering takeaway from the Congress was the reality that access to Parkinson's care remains out of reach for far too many people.
Around the world, millions of people living with Parkinson's struggle to access the medications, therapies, and specialists they need. Even when care is available, affordability can become a barrier.
I experienced that reality firsthand.
Recently, I sought occupational therapy to help manage one of my Parkinson's symptoms. The session lasted 45 minutes and the total charge was $750. Even with insurance covering roughly half the cost, I was left with a bill of nearly $375.
When you're living with a progressive neurological disease, treatment is not a luxury. It is a tool that can help maintain independence, function, and quality of life. Yet costs like these force many people to make difficult decisions about the care they can afford.
The Parkinson's community is working tirelessly to advance research and develop better treatments. But breakthroughs alone are not enough. Those treatments, therapies, and support services must also be accessible to the people who need them.
Access to care should not depend on where you live, what insurance you have, or how much money you can afford to spend.
4. We Need Science Written for Real People
People living with Parkinson's may be among the most informed and engaged patients you'll ever meet, but most of us are not scientists.
We read studies. We attend webinars. We follow clinical trials and research updates because we are searching for answers and looking for anything that might help us live better today and tomorrow.
The challenge is that much of the research is written by scientists for scientists. Scientific papers are filled with technical language, complex terminology, and assumptions that can make them difficult for the average person to understand.
Since I started writing about Parkinson's research, I've realized that one of the biggest gaps isn't a lack of information. It's accessibility. The science matters, and the discoveries matter, but they can only make a difference if people understand what they mean and how they apply to their lives.
We need more people who can bridge that gap by translating complex research into clear, practical language. Knowledge shouldn't be locked behind scientific jargon. It should be accessible to the people who need it most.
5. Lifestyle Is Taking Center Stage
One of the most encouraging themes throughout the World Parkinson Congress was the growing recognition that living well with Parkinson's requires more than medication alone.
For years, treatment conversations focused primarily on drugs and procedures. While those remain essential, there is now a much deeper appreciation for the role that exercise, nutrition, sleep, stress management, and social connection play in managing the disease and improving quality of life.
You could see that shift everywhere. The gyms were packed every morning. People were not waiting passively for the next breakthrough. They were taking action and investing in their health today.
But movement alone is not enough. Jimmy Choi, a leading Parkinson's advocate and research champion, spoke about the importance of training like an athlete. The message was clear: move with purpose. Challenge yourself. Build strength, endurance, balance, and resilience. Exercise is not simply about staying active; it is about training for the life you want to live.
No one suggested that lifestyle interventions replace medication. Instead, there was excitement around the growing body of evidence showing that healthy daily habits can help improve symptoms, preserve function, and support long-term well-being.
That may have been the most empowering message of all. While researchers continue working toward tomorrow's breakthroughs, there are meaningful steps we can take today.
6. Constipation Is Real
I couldn’t write this without mentioning the topic that came up about every five minutes, fittingly since I was standing at a booth talking about fiber. Let’s just say it was a very “regular” conversation.
As a vendor sharing NeuroFiber Bars, I had hundreds of conversations with people living with Parkinson’s. Over and over again, constipation wasn’t a side note, it was often one of the first things people brought up.
This isn’t just a minor inconvenience. For many, it’s a daily struggle that affects comfort, quality of life, and even how consistently medications seem to work.
What stood out most was the growing awareness that constipation may be more than just a symptom to manage. Research increasingly suggests it can appear years and sometimes even decades before a Parkinson’s diagnosis.
That raises an important question. Instead of automatically reaching for another over the counter fix, should we be spending more time understanding why this is happening in the first place?
If constipation is tied to early changes in the gut that precede motor symptoms, then what’s happening in digestion may offer clues that go far beyond digestion itself.
Constipation is real. It deserves attention. And it may be quietly pointing us toward something much bigger about Parkinson’s.
Explore why constipation is a neurological red flag.
My Biggest Takeaway
After speaking with more than 100 people, one thing became clear. There is a red thread running through the entire Parkinson’s community. It is not one idea or one treatment, but a shared determination that connects everyone in the room.
The Parkinson’s community is not sitting around waiting for a cure.
People are educating themselves. They are advocating for better care. They are exercising. They are experimenting with nutrition. They are supporting one another. And they are demanding answers.
That red thread shows up in different ways, but the message is consistent. Parkinson’s is personal. Environmental factors matter. Access to care is unequal. Science must be understandable. Lifestyle matters. And the gut may be telling us something important long before symptoms appear.
Most of all, I left inspired.
Inspired by the researchers searching for answers.
Inspired by the care partners showing up every day.
And inspired by the people living with Parkinson’s who continue to face this disease with courage, resilience, and hope.
For me, that red thread was the greatest takeaway of all.
