“The HFE gene is routinely tested for in most Western countries including Australia when assessing people for haemochromatosis – a disorder that causes the body to absorb too much iron. Our findings suggest that perhaps this testing could be offered to men more broadly,” Professor Olynyk said.
“While the HFE gene is critical for controlling iron levels in the body, we found no direct link between iron levels in the blood and increased dementia risk in affected men.
“This points to other mechanisms at play, possibly involving the increased risk of brain injury from inflammation and cell damage in the body.”
