Iron metabolism is associated with the gene hemochromatosis (HFE Human genome nomenclature committee ID:4886), and mutations in HFE are a cause of the iron mismetabolism disease, hemochromatosis. Effects of hemochromatosis and transferrin gene mutations on peripheral iron dyshomeostasis in mild cognitive Feb 5, 2021 · Men with iron overload due to hereditary hemochromatosis are at increased risk of developing dementia, an analysis of UK Biobank data indicates. The Australian PATH cohort study (n = 1354) found an increased risk of cognitive impairment with higher levels of iron intake (HR 1. 19 This suggests that haemochro - matosis itself may cause cognitive decline. , heightened dietary iron induced cognitive deficits in aged mice while showing no discernible impact in younger mice [28]. We postulate that in our described case, haemochromatosis may have accelerated the patient’s cognitive decline. Assogna , 4 J. QSM could be used to quantify brain iron overload in vivo , highlighting its potential clinical application for assessing cognitive impairment in patients with thalassemia.
