An autistic savant (historically described as an idiot savant) is a person with both autism and savant syndrome. Savant syndrome describes a person having a developmental or mental handicap of some sort with extraordinary mental abilities not found in most people. This usually means (but not in all cases) a lower than average general intelligence (IQ) but very high narrow intelligence in one or more fields. Savant syndrome skills involve striking feats of memory and arithmetic calculation and sometimes include unusual abilities in art or music. Savant syndrome is sometimes abbreviated as "savantism", and individuals with the syndrome are often nicknamed savants. This can be a source of confusion since a savant can also mean a person of learning, especially one of great knowledge in a particular subject.

Abilities

Savant syndrome is usually recognized during early childhood as coincident with other developmental abnormalities; the plurality of cases occur in children with autism. Males with savant syndrome outnumber females by roughly 6:1[1]—slightly higher than the disparity for autism spectrum disorders.

Most autistic savants have extensive mental abilities called splinter skills.[2] Why autistic savants are capable of these astonishing feats is not quite clear. Some savants have obvious neurological abnormalities (such as the lack of corpus callosum in Kim Peek's brain). Many savants are known to have abnormalities in the left hemisphere of the brain.[3]

There are only about 100 recognized prodigious savants in the world.[4]
