Parkinson’s disease is a serious condition that affects how people move. It happens when certain brain cells stop working properly, leading to problems like shaking, stiff muscles, and trouble with balance. Over time, these symptoms can get worse, making everyday activities like walking and talking more difficult.
Scientists at Queen Mary University of London recently made an unexpected discovery about Parkinson’s disease. They found that some common epilepsy drugs might be linked to a higher risk of developing the condition.
Epilepsy is a disorder that causes seizures, and doctors often prescribe special medications called antiepileptic drugs to help control these seizures. These drugs work by calming abnormal electrical activity in the brain. But in this study, researchers noticed a connection between taking these drugs and a greater chance of developing Parkinson’s disease.
To explore this, the scientists examined medical records from a large group of people. They looked at data from 1,433 patients who had Parkinson’s and compared them with 8,598 people who did not have the disease. They focused on whether these people had taken certain epilepsy drugs, including carbamazepine, lamotrigine, levetiracetam, and sodium valproate—medications commonly used to control seizures.
The results showed a clear pattern: People who had taken epilepsy drugs were more likely to have Parkinson’s disease. The risk seemed to increase with the amount of medication taken. Those who had been prescribed these drugs more often or were taking more than one type had an even higher chance of developing the condition.
This is an important finding because it’s the first study to look at multiple epilepsy drugs and their possible link to Parkinson’s disease. The results raise serious questions. Could these drugs be playing a role in triggering Parkinson’s in some people? Or is there another reason why people taking these medications seem more likely to develop the disease?
It’s important to note that this study does not prove that epilepsy drugs cause Parkinson’s disease.
There may be other factors involved. For example, epilepsy itself has been linked to a higher risk of Parkinson’s, so it’s possible that the disease, rather than the drugs, is the real reason for the increased risk. However, the study’s findings are strong enough that scientists say more research is needed.
If further studies confirm this link, doctors may need to be more careful when prescribing epilepsy drugs, especially for people who might already be at risk for Parkinson’s. Researchers may also look for safer alternatives or ways to reduce the risk for those who need these medications.
While this discovery raises concerns, it could also lead to something positive. If scientists understand how epilepsy drugs might be linked to Parkinson’s, they could develop new treatments or protective strategies in the future.
For now, this research—led by Daniel Belete and published in JAMA Neurology—is just the first step. More studies will be needed to fully understand what is happening and how to best protect people from Parkinson’s disease.
