More | than 850,000 people in the UK live with dementia, with numbers set to rise rapidly over the next decade.
Researchers are trying to work out if it can be treated - or prevented - and one new study suggests boosting iron levels could lower the risk for women.
Research into 16,000 men and women, half of whom had dementia, found women with the condition were twice as likely to have been diagnosed with iron-deficiency anaemia.

One theory is anaemia may cut the amount of oxygen getting to the brain - a lack of iron stops blood cells carrying oxygen from working properly. However, the study did not show the same results in men.

But despite young people being at high risk, research shows stigmas around mental illness still exist on Britain's university campuses.
Six out of 10 students struggle to believe their peers when they say they have a mental-health condition. And many who admitted needing help say this has led to them suffering "humiliation" and "discrimination", according to a study by The Priory Group.
Dr Ian Drever, consultant psychiatrist, said: "It's important students share how they feel with a friend or a professional. They need to acknowledge to them that they are not well and that it's time to get help."

The particles are coated with a protein made by the immune system to fight disease, and it can recognise cancer cells.
Experts say the mouthwash could enable particles to latch on to cancerous growths, and doctors could locate affected areas.
Researchers at Bar-Ilan University, Israel, say trials are due to start later this year.
