That’s the average for people in their early 80s, but risk rises very fast after that.

About 1 in 3 people that reach 90 are likely to die from dementia complications.

With modern early detection and treatment. The incidence of severe dementia can probably be reduced significantly in the future.

The study data shows there is no difference across all three groups so magnesium was not a factor

This article actually says:

The articles that are written by journalists are more readable.

Correlation isn’t causation, but it will probably be decades before magnesium investigated by pharmaceutical companies if it happens.
