Brain scan breakthrough reveals why Parkinson’s drugs don’t always work

Researchers are using an advanced brain imaging method called MEG to understand why Parkinson’s drug levodopa doesn’t work equally well for everyone. By mapping patients’ brain signals before and after taking the drug, they discovered that it sometimes activates the wrong brain regions, dampening its helpful effects. This breakthrough could pave the way for personalized treatment strategies, ensuring patients receive medications that target the right areas of their brain more effectively.
