It is a condition that can be caused by a number of diseases that gradually destroy nerve cells and damage the brain, resulting in a decline in cognitive functions, according to the World Health Organization.

While age is still the strongest known risk factor for dementia, researchers have found a set of 12 "potentially modifiable risk factors," according to The Lancet Commission's 2020 report:

"Together the 12 modifiable risk factors account for around 40% of worldwide dementias, which consequently could theoretically be prevented or delayed," according to The Lancet.
