David Hessl, a UC Davis M.I.N.D. Institute fragile X syndrome researcher, and a team of collaborators have devised a new system of scoring IQ tests taken by children with fragile X syndrome. Fragile X is a genetic disorder that causes intellectual disabilities, including autism. Treatment of fragile X syndrome depends on its manifestations in the individual, and range from behavioral therapy to medication. Widespread use of these new normalized scores would allow physicians to better treat their patients, Hessl said. Details of the new method are published online in the Journal of Neurodevelopmental Disorders.
