چکیده انگلیسی
Hyperlexia is a condition rarely reported in Spanish-speaking children, characterized by the ability to recognize written words without formal training. We present two unrelated autistic children with hyperlexia from Colombia (South America) who were followed for 8Â years with formal neuropsychological evaluations of language, motor skills, visual perception, attention and behavior. Both children taught themselves to read before 5Â years of age but showed minimal comprehension; both displayed obsessional reading and difficulties in social skills and attention. Brain CT scans were normal. Hyperlexia has been associated with hyperactivation of the left superior temporal cortex; we conclude that the orthographic route is a probable mechanism for the development of hyperlexia.
