Parkinson’s disease is a serious condition that slowly affects how people move. It often begins with mild symptoms like shaking hands, stiff muscles, or slower movements.
Over time, everyday activities like walking, talking, or even eating can become very hard. This illness touches many lives, and scientists around the world are working to better understand what causes it and how to treat or prevent it.
A recent study from Queen Mary University of London has made a discovery that could help us think differently about Parkinson’s. The researchers focused on a group of medications called antiepileptic drugs.
These drugs are normally given to people with epilepsy to help stop seizures by calming the brain’s electrical activity. But the scientists wanted to see if these same drugs might be linked to Parkinson’s disease in some way.
To find out, the researchers looked at medical records from a large group of people in the UK. They studied 1,433 people who had been diagnosed with Parkinson’s and compared them to 8,598 people who did not have the disease. The key question was: had these people ever taken antiepileptic drugs like carbamazepine, lamotrigine, levetiracetam, or sodium valproate?
The results were surprising. People who had taken these seizure medications were more likely to develop Parkinson’s disease than those who hadn’t. And the risk wasn’t the same for everyone.
The more prescriptions a person had for these drugs, and the more types they had taken, the higher their chances seemed to be. In other words, the risk increased depending on how much and how often the drugs were used.
This kind of result is called a “dose-dependent” relationship, which means the amount of the drug matters. It’s the first time researchers have looked so closely at this wide range of epilepsy medications and their possible connection to Parkinson’s. That makes this study an important step forward in understanding the bigger picture.
But it’s also important to say what this study doesn’t show. It doesn’t prove that these drugs cause Parkinson’s. There could be other reasons behind the link.
For example, some people might have early signs of Parkinson’s before they even get diagnosed, and those early symptoms might look like seizures or other problems that lead doctors to prescribe antiepileptic drugs. So, we don’t know yet whether the drugs themselves play a direct role in causing the disease.
Even so, the findings are valuable. Doctors who treat people with epilepsy or other conditions that require these drugs might want to consider the long-term effects more carefully—especially in patients who could be at risk for Parkinson’s.
It’s part of a growing movement in healthcare called “personalized medicine,” where treatment decisions are made with each person’s unique risks and needs in mind.
This study also shows how complex the brain is, and how closely connected different conditions can be. Epilepsy and Parkinson’s may seem like very different problems, but they might have links we’re only beginning to understand.
Researchers still have a lot of work to do. Future studies will need to explore exactly how these drugs could affect the brain and whether some people are more vulnerable than others. But this is a good reminder that all medications, even those we’ve used for years, can have effects we don’t fully expect.
In the end, discoveries like this one help improve care for people with epilepsy and Parkinson’s. They guide doctors toward safer treatment choices and give scientists new ideas for how to protect the brain. With more research, we may one day learn how to lower the risk of Parkinson’s or even stop it before it starts.
