Scientists are still not sure of why a bunch of US diplomats in Cuba experienced mysterious neurological symptoms. However, they’re still in search of solutions. A new study revealed today in JAMA by the University of Pennsylvania reveals that brain changes have been present in US government officers who had been stationed in Havana. However, there’s still no proof of the theory that a sonic weapon had attacked the diplomats.
The examine carried out superior brain imaging on 40 government personnel who have been stationed in Cuba. A bunch of 48 healthy patients had been used as control. In comparison with the management group, the brains of the Cuba sufferers confirmed distinct differences in brain volume and connectivity. There was a decreased white matter in the affected patients. Changes in tissue volume particularly impacted the cerebellum — the region of the brain responsible for executive functioning.
“The areas implicated in the sufferers’ brains, particularly the cerebellum as well as the visuospatial and auditory networks, align with the neurological signs that had been noticed in the patients,” mentioned lead author Ragini Verma, Ph.D., professor of radiology and head of the imaging lab at the University of Pennsylvania. Verma stated the changes had been evident even after scientists excluded the outcomes of sufferers with a historical past of brain injuries.
Still, outside scientists cast doubt on the examine; arguing that its methods are far from iron-clad. First off, the imaging methods used in the sufferers aren’t meant to search out disease, neuroscientist Douglas Fields informed Gizmodo.
