The brains of men and women are wired differently and could explain why they suffer different mental illnesses, say scientists.

They measured 45 areas and found the frontal lobe, for decisions and problem-solving, was bigger in women.

Men were bigger in areas used for space perception, social and sexual behaviour.

Women are more likely to suffer depression from a lack of serotonin, while boys are more likely to have autism due to a hormone in the brain, New Scientist mag said.
