A new study reveals that a common type of brain scan used to detect Alzheimer’s disease may also help identify individuals at risk for other neurodegenerative conditions before symptoms appear. Researchers found that subtle changes in brain structure, visible through advanced imaging techniques, could serve as early biomarkers for diseases like Parkinson’s and frontotemporal dementia. The findings suggest potential for earlier intervention and personalized treatment approaches, though further validation is needed. Experts emphasize the need for broader testing to confirm whether these imaging patterns reliably predict disease progression across different patient groups.
