> The syndrome is unexplained, but US scientists say it is most probably caused by directed microwave radiation.
A lot of scientists, American and non-American alike, doubted the microwave weapon theory.
> The US accused Cuba of carrying out "sonic attacks", which it strongly denied, and the incident led to increased tension between the two nations.
The sound of the "sonic attacks" turned out to be the sound of indigenous Cuban crickets. Oops! https://www.the-scientist.com/news-opinion/recording-of-soni...

> A 2019 US academic study found "brain abnormalities" in the diplomats who had fallen ill, but Cuba dismissed the report.
As did a lot of academics:
"The latest brain scans may provide fresh evidence of some injury, but the study was not without critics and some researchers have questioned whether there was any kind of attack at all.
“Finding evidence of brain change doesn’t provide evidence of brain injury or damage,” said Dr. Jon Stone, a professor of neurology at the Centre for Clinical Brain Sciences at the University of Edinburgh, who was not involved in the study.
Dr. Sergio Della Sala, a professor of human cognitive neuroscience also at the University of Edinburgh, in an email called the study “half baked.”
He noted that 12 of the affected workers who had a history of concussion prior to going to Cuba were included in the analyzes. “In comparison, none of the controls declared previous brain injury. This in itself could cause statistical group differences,” Della Sala said."

In his commentary Della Sala writes: "The JAMA article represents a case of poor neuropsychology; clinically inappropriate and methodologically improper." https://www.sciencedirect.com/science/article/abs/pii/S00109...
