Savant
Savant syndrome ( SAV-ənt, sə-VAHNT, US also səv-AHNT) is a phenomenon where someone demonstrates exceptional aptitude in one domain, such as art or mathematics, with such aptitude often coinciding with some form of social or intellectual impairment.
Those with the condition generally have a neurodevelopmental condition, such as autism, or have experienced a brain injury. About half of cases are associated with autism, and these individuals may be known as autistic savants. The other half often have some form of central nervous system injury or disease. While the condition usually becomes apparent in childhood, some cases develop later in life.
