If you’re a man carrying a common genetic variant, you could be twice as likely to develop dementia in your lifetime compared to women.

An Australian study made the connection between risk and variants in the haemochromatosis gene, which is critical for regulating iron levels in the body.

It’s not yet known why having two copies of this variant increases the risk of dementia for males but not females.
