Regular exercise modulates iron storage and trafficking in the brain and skeletal muscles, and physical activity reduces cortical hepcidin. The findings reveal how exercise can be beneficial for those with Alzheimer's disease.
Researchers found tiny deposits of elemental copper and iron in the brains of Alzheimer's patients. The findings may shed new light on how these elemental metals contribute to Alzheimer's development and progression.
Researchers hypothesize vitamin B1 (thiamine) deficiency may play a significant role in dementia associated with alcohol use disorder. It is known iron deposits in the brain contribute to neurodegenerative diseases. Those with AUD have elevated levels of both iron in their blood and thiamine deficiency. Thiamine is vital for maintaining the blood-brain barrier. Thiamine deficiency associated with AUD disrupts the integrity of the BBB, allowing for more iron deposits within the brain and leading to oxidative tissue damage.
Iron accumulation in the brain's neocortex has been linked to cognitive decline in people with Alzheimer's disease.
Iron levels in the basal ganglia steadily increase throughout development and, in two sub-regions, continue to increase into adulthood. Decreased levels of iron in the putamen was correlated with impaired cognitive performance involving reasoning and spatial processing. Findings suggest the brain requires iron for healthy cognitive development.
Study finds no association between mineral levels or dietary mineral intake and an increased risk of multiple sclerosis.
Analyzing genetic data from over 48,000 people, researchers discovered higher iron levels are associated with an increased risk of cardioembolic stroke.
Researchers have identified an over accumulation of iron in the mitochondria of mice genetically engineered to have Huntington's disease.
Findings could provide a new avenue for treating multiple sclerosis, researcher report.
A new neuroimaging study finds iron is distributed in an unusual way in the brains of people with Parkinson's disease.
