Abstract

Savant syndrome is a rare and unusual condition that occurs in the presence of severe developmental disabilities, disorders, and injuries. The syndrome can be congenital from birth to childhood or acquired as a result of a brain injury or damage to the central nervous system. There are several findings that indicate that savant syndrome usually occurs with significant brain metabolism alterations resulting in critical brain network changes. These types of changes in the brain are usually explained by the “tyranny of the left hemisphere” theory, which indicates the inhibition of the left hemisphere to allow the right hemisphere to develop savant abilities. Another way to temporarily simulate these types of changes in the brain can be through different neuromodulation techniques such as transcranial magnetic stimulation and transcranial direct current stimulation. Such neuromodulation techniques might help us discover the “hidden talent” potential through modulating the brain network metabolism. We herein discussed the types of savant syndrome along with its relation to specific neurometabolic network alterations. Furthermore, we provide a perspective on how newly developed neuromodulation and cognitive rehabilitation techniques can help simulate savant syndrome in healthy individuals through modulating the brain network activity.

Keywords: Savant syndrome, autism spectrum disorder, traumatic brain injury, acquired savant syndrome, congenital Savant syndrome, epilepsy.
