Summary

Story summary

A Johns Hopkins University study shows that quantitative susceptibility mapping (QSM) MRI can predict mild cognitive impairment (MCI) in older adults without cognitive issues.
The study tracked 158 participants for up to 7.7 years, finding a link between higher brain iron levels and MCI risk.
Increased iron disrupts cognitive functions and may signal neurodegeneration in memory-related brain areas.
QSM MRI is noninvasive and cost-effective, potentially enabling early Alzheimer's interventions.
Researchers plan to standardize QSM for wider clinical application, with iron accumulation as a future treatment target.
