National Academies, December 2020, commissioned by the State Department: directed, pulsed radio-frequency energy "appears to be the most plausible mechanism" for the Havana Syndrome cases it studied.
Overall, directed pulsed RF energy, especially in those with the distinct early manifestations, appears to be the most plausible mechanism in explaining these cases among those that the committee considered, along with PPPD as a secondary reinforcing mechanism, as well as the possible additive effects of psychological conditions.
