Parkinson’s disease is a long-term condition that slowly damages parts of the brain. It affects how people move and control their muscles. Common symptoms include shaking, stiff muscles, and trouble with balance and coordination. These symptoms usually get worse over time, making it harder for people to do everyday tasks.
Doctors still don’t know exactly what causes Parkinson’s, but researchers are looking into different possibilities. One area of interest is whether certain medications might play a role in the development of this disease.
A recent study by scientists at Queen Mary University of London looked at a possible link between some commonly used seizure medications and the risk of developing Parkinson’s disease. These drugs, known as antiepileptic drugs, are often prescribed to people who have epilepsy or other conditions that cause seizures.
The researchers used health records from people living in the UK. They compared two groups: 1,433 people who had been diagnosed with Parkinson’s and 8,598 people who did not have the disease.
They looked at the prescription histories of both groups to see if they had taken certain antiepileptic drugs. These included carbamazepine, lamotrigine, levetiracetam, and sodium valproate.
What they found was surprising. People who had taken these seizure medications, especially at higher doses or for longer periods, had a greater chance of developing Parkinson’s disease.
The more they took or the more different drugs they used, the higher their risk appeared to be. This kind of pattern is called a “dose-response” relationship, and it often suggests a real connection rather than just a coincidence.
This study is important because it’s the first to look at a wide range of seizure medications and how they might relate to Parkinson’s. However, the researchers say that more studies are needed to be sure about these results. It’s not yet clear why these drugs might increase the risk, or if other factors could be involved.
Understanding how and why this link exists could give scientists new clues about how Parkinson’s starts. It could also help doctors find ways to lower the risk or develop new treatments in the future.
Still, it’s very important to remember that antiepileptic drugs help many people live normal, healthy lives. For people with epilepsy or other seizure disorders, these medications prevent seizures, which can be dangerous or even life-threatening. So, even if there is a small risk, it has to be carefully weighed against the benefits these drugs provide.
Doctors and patients may need to have more detailed conversations when starting or continuing treatment with these medications. The goal should always be to find the safest and most effective plan for each person.
In the end, this study adds an important piece to the puzzle of Parkinson’s disease. It opens up new questions and points toward areas that need more research.
Scientists will continue to investigate how seizure medications might affect brain health, and what steps—if any—might help reduce risk. Until then, people taking these drugs should not stop or change their treatment without talking to their doctor.
