Washington DC, June 29 -- Simon Fraser University 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 personalised treatment strategies, ensuring patients receive medications that target the right areas of their brain more effectively.

The new study by the Simon Fraser University (SFU) researchers, published in the journal Movement Disorders, looks at why levodopa - the main drug used in dopamine replacement therapy - is sometimes le...
