Cuba calls on US and Canada to investigate 'sonic attack' claims

Description

A formal assessment of the American diplomats’ health commissioned by the US government was published in March by doctors at the University of Pennsylvania. The preliminary report in the Journal of the American Medical Association describes a new syndrome that resembles persistent concussion in people who have not received blows to the head.

But in a letter published in the Journal of Neurology, Sergio Della Sala and Robert McIntosh, both neuroscientists at the University of Edinburgh, claim the US report is seriously flawed.
