Common Myths About Parkinson’s Disease – Busted
Introduction
When most people hear “Parkinson’s disease,” they immediately think of tremors or shaky hands. While tremor is a well-known symptom, Parkinson’s is far more complex than that. It’s a chronic and progressive condition that affects everyone differently—and unfortunately, there are still many misconceptions floating around about what it is, how it progresses, and how it can be treated.
Let’s break down some of the most common myths and set the record straight with facts, expert insight, and recent research.
Frequently Asked Questions About Parkinson’s Disease (and the Truth Behind the Myths)
1. “Parkinson’s only affects movement.”

Not true. Yes, Parkinson’s is classified as a motor disorder, but it also comes with a host of nonmotor symptoms that can show up even before movement-related issues appear. These can include:
- Cognitive issues or even dementia
- Depression and anxiety
- Sleep disturbances
- Pain
- Apathy
- Sexual dysfunction
- Bowel incontinence
Many people overlook these symptoms, but they can be just as—if not more—disabling than the motor symptoms. According to research, in the later stages, these nonmotor symptoms can have a huge impact on quality of life, independence, and life expectancy.
2. “Parkinson’s medication only works for a few years.”
This is a long-standing myth, especially about levodopa, one of the most commonly prescribed Parkinson’s medications. Many people believe it only works for about five years—but that’s simply not true.
Levodopa can continue to relieve symptoms for decades. However, as Parkinson’s progresses, the brain slowly loses the enzyme aromatic acid decarboxylase (AADC) that helps convert levodopa into dopamine. This loss of enzyme—not the medication itself—is what reduces the drug’s effectiveness over time.
So while each dose may eventually work for a shorter period (known as “wearing-off”), the medication doesn’t suddenly stop working because you’ve been on it too long.
3. “Levodopa makes Parkinson’s symptoms worse.”
This is another big misconception. Levodopa does not worsen Parkinson’s symptoms.
It’s true that some people develop dyskinesia—involuntary, jerky movements—while taking levodopa. But this side effect is more related to the progression of the disease than how long you’ve been taking the medication.
According to the American Parkinson’s Disease Association (APDA), dyskinesia usually appears after 4–10 years of levodopa use. And in many cases, the mobility benefits from levodopa far outweigh the side effects of dyskinesia. In other words: better movement with some extra motion beats being immobile.
4. “Tremor always means Parkinson’s.”
Not necessarily. Tremor is a hallmark symptom of Parkinson’s, but not all tremors are caused by Parkinson’s.
Other conditions can also cause tremors, such as:
- Drug-induced parkinsonism
- Vascular parkinsonism
- Essential tremor
- Dystonic tremor
- Psychogenic disorders
- Dopa-responsive dystonia
A proper diagnosis is key. Don’t jump to conclusions based on tremors alone.
5. “Doctors can accurately predict how Parkinson’s will progress.”
This would be helpful—but unfortunately, it’s not that simple. Parkinson’s affects every person differently. Some progress quickly, others slowly, and the range of symptoms can vary widely.
Scientists still aren’t entirely sure why some people have more severe symptoms or faster progression than others. It could be related to how the disease starts in the brain, but more research is needed to fully understand these differences.
6. “Everyone with Parkinson’s has a tremor.”
Actually, about 20% of people with Parkinson’s never develop a tremor at all.
In some cases, nonmotor symptoms show up first, before any shaking or movement problems. Experts believe this could be due to which parts of the brain are affected. For example, some scientists think that a severe tremor is linked to the loss of dopamine neurons in a specific brain region near the substantia nigra—the retrorubral area.
7. “Parkinson’s causes sudden flare-ups.”
Unlike conditions like multiple sclerosis, Parkinson’s doesn’t usually involve sudden flare-ups or relapses. It typically progresses slowly and steadily over time, although symptoms might fluctuate a bit throughout the day.
If someone with Parkinson’s suddenly experiences a sharp worsening of symptoms, it’s usually due to other issues like:
- Infections (the most common cause of sudden worsening)
- Stress or anxiety
- Missing or mismanaging medications
- Medication side effects
- Health problems after surgery
The good news? Studies show that over 80% of these sudden symptom increases are treatable or reversible.
8. “Only medication can help.”
Wrong again. While medication is a critical part of managing Parkinson’s, it’s not the only tool in the toolbox.
Exercise—especially when started early—can significantly improve symptoms and even slow the progression of the disease. Research has shown that people who exercise for at least 2.5 hours a week have a slower decline in quality of life than those who don’t.
And it’s not just physical benefits—exercise can also improve sleep and cognitive function in people with Parkinson’s. So get moving! Regular activity is one of the best ways to take control of the disease.
9. “Parkinson’s is a death sentence.”
Let’s clear this up: Parkinson’s itself is not fatal.
Many people with Parkinson’s live long, meaningful lives. That said, it can increase the risk of serious health issues, especially in the later stages. For example:
- Falls are a major concern and can lead to complications or surgery.
- Pneumonia is another risk, especially if swallowing becomes difficult, causing food to enter the lungs.
While Parkinson’s may shorten life expectancy somewhat—particularly in those who develop it at a younger age—it’s not always the case. Many people live for decades after diagnosis, especially with proper care and support.
Conclusion: Understanding Parkinson’s is Key
There’s a lot of misinformation out there about Parkinson’s disease, but we now know more than ever. From medication myths to exercise benefits, the truth is that Parkinson’s is manageable, and many of the fears surrounding it are based on outdated information.
The key takeaway? Every person’s experience with Parkinson’s is unique. With the right mix of medication, exercise, support, and knowledge, it’s possible to lead a full, active life.
If you or someone you love is living with Parkinson’s, don’t let myths shape your understanding—stay informed, stay proactive, and stay hopeful.
