Parkinson’s disease is a long-term condition that slowly affects the brain and nervous system.
It causes shaking, stiff muscles, and problems with balance and movement. Over time, these symptoms get worse and can make everyday tasks harder.
Millions of people around the world live with Parkinson’s, but doctors still don’t fully understand what causes it. Some researchers are now looking into whether certain medications might play a role.
One group of medications under investigation are antiepileptic drugs. These are medicines used to treat seizures in people with epilepsy and other conditions that cause convulsions. A new study from Queen Mary University of London, published in JAMA Neurology, has looked closely at this possible link.
The researchers wanted to find out if people who take certain antiepileptic drugs are more likely to develop Parkinson’s disease. They studied health records from a large number of people in the UK.
The study compared 1,433 people who had been diagnosed with Parkinson’s disease to 8,598 people without the disease. This second group served as a control group to help researchers spot differences.
They looked at prescription records to see if people had taken any of four commonly used antiepileptic drugs: carbamazepine, lamotrigine, levetiracetam, and sodium valproate.
The findings showed that people who had taken these drugs had a higher risk of developing Parkinson’s disease, especially if they had taken more than one type of drug or had taken higher doses.
This kind of pattern is called a “dose-response relationship.” It means that the more of a drug someone takes, the stronger the effect—or in this case, the higher the risk. This discovery is important because it is one of the first studies to examine several different antiepileptic drugs and their possible link to Parkinson’s.
Even though this study doesn’t prove that antiepileptic drugs directly cause Parkinson’s disease, it does suggest a possible connection that needs to be explored further. Learning more about how these drugs might be involved in the development of Parkinson’s could help doctors better understand the disease and how to prevent it.
Still, it’s important to remember that antiepileptic drugs are very useful. They help many people live better lives by stopping seizures, which can be dangerous if untreated. For people with epilepsy, these medications are often necessary. That’s why any possible risks must be carefully weighed against the benefits.
Doctors need to take a balanced approach when prescribing these drugs, especially for patients who may need them long-term. It’s also important for patients and doctors to talk openly about the risks and benefits of any treatment.
This research is an important step in understanding more about Parkinson’s disease. Future studies will try to confirm these results and figure out why antiepileptic drugs might be linked to Parkinson’s. Scientists hope to uncover the biological reasons behind the connection and use that knowledge to improve care.
As research continues, the goal is to help both patients and doctors make informed decisions about treatment. For now, people taking antiepileptic drugs should not stop their medication without talking to their doctor. Instead, they should stay informed and work closely with their healthcare providers to choose the best plan for their health.
