Savant Syndrome. Those suffering of Savant syndrome often score low on intelligence tests but have an island of brilliance - some incredible ability, as in computation, drawing, or musical memory. Many are also diagnosed with autism, which mostly afflicts males, and about 4 in 5 savants are males. Savants may have virtually no language ability, yet may be able to compute numbers as quickly and accurately as an electronic calculator, or identify almost instantly the day of the week that corresponds to any given date in history.
