Dementia due to iron deficiency (Q86451): Difference between revisions

Iron is a mineral thought to be implicated in Alzheimer neuropathology. It has been found to co-localise with amyloid plaques and is thought to be implicated in the pathological process leading to amyloid plaque aggregation. Iron plasma levels have also been found to be positively associated with cognitive function in elderly individuals. These associations were detected even in the absence of anaemia, where low iron levels might lead to lower haemoglobin levels and possible cerebral hypoxia, consequently other mechanisms might also be at play.
