[Dyslexia as a multideficit disorder]

The article provides a review of research on dyslexia. Various views on the role of genetic and environmental factors in the etiology and pathogenesis of this disorder are examined. The results of neurophysiological and neuropsychological studies are presented, indicating a disturbance of some higher mental functions in dyslexia. The main neurocognitive deficits observed in dyslexia are considered: a disturbance of certain parameters of attention and working memory, a decrease in the speed of information processing, and insufficient automation of new skills. Based on the data presented, dyslexia appears to be a multifactorial and multideficit disorder.
