Novel detection method for iron in Alzheimer’s brain
For many years, scientists have observed a correlation between Alzheimer’s disease and a surplus of iron in the brain. However, a causal link between the two has not been proven yet. We lack knowledge concerning the specific form of iron that is involved in the development of neurodegenerative diseases.…
