AVM

A brain AVM disrupts the vital exchange of blood between the lungs and heart.

It’s unclear what causes a brain AVM.

As a result of this suggestion, it has become known as the “Ave Maria Stone,” or the “AVM stone.”

The coincidence of dates—1362 on the Kensington Runestone, 1363 on the AVM Stone—is either remarkable corroboration, or should set alarm bells ringing.

The “mooring stones” and the more recent “AVM Stone” are best regarded as well-meaning attempts to corroborate an original find, the authenticity of which is highly suspect.
