A new study showed that men with the most a common genetic disease in the Western world, the probability of developing dementia is higher than in men without defective genes.

Researchers from the University of Exeter and the University of Connecticut found that men with two defective genes that cause hemochromatosis are more likely to get liver cancer , arthritis and weakness compared to men without the defective genes.

Now, a new analysis of a group of more than 335,000 people of European descent has shown that men who carry two defective genes that cause hemochromatosis are more likely to suffer mental retardation.

The scientists found that 25 of 1,294 men with two defective genes developed dementia, 83 percent more often than men without the defective genes.

The team also found iron accumulation in key brain regions associated with dementia in a subgroup of men with two defective genes that cause hemochromatosis.
