Treffert, now retired from the University of Wisconsin School of Medicine, diagnosed Amato with “acquired savant syndrome.” In the 30 or so known cases, ordinary people who suffer brain trauma suddenly develop almost-superhuman new abilities: artistic brilliance, mathematical mastery, photographic memory.

Is a savant a genius?

However, studies of brain function, such as positron emission tomography (PET), single photon emission CT (SPECT) or functional MRI, are much more informative regarding savant syndrome, and, indeed, autism itself, since these newer techniques provide information about the brain at work, rather than simply viewing brain architecture.
