Scientists have told which men should be afraid of dementia

A new study has shown that men with the most common genetic disease in the Western world are more likely to develop dementia than men without defective genes.

Researchers from the University of Exeter and the University of Connecticut have found that men with two defective genes that cause hemochromatosis are more likely to develop liver cancer, arthritis and frailty than men without the defective genes.

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

The scientists found that 25 of 1294 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 areas of the brain associated with dementia in a subset of men with two defective genes that cause hemochromatosis.
