- Scientists have developed a groundbreaking technique, ASA-PD, to visualise tiny brain clusters called alpha-synuclein oligomers, believed to trigger Parkinson's disease.
- The technique uses ultra-sensitive fluorescence microscopy, enabling researchers to directly observe these previously unseeable protein clumps in human brain tissue.
- The study found that oligomers were larger and brighter, with a unique sub-class, in brain samples from Parkinson's patients compared to healthy individuals.
- This breakthrough is expected to deepen understanding of Parkinson's development, potentially paving the way for new treatments and offering an "atlas of protein changes" across the brain.
- Experts suggest this method could also be applied to research into other neurodegenerative conditions such as Alzheimer's and Huntington's, with Parkinson's UK calling it an "important step forward".
