[Sensory integration and fragile X syndrome].
The fragile X syndrome is the most common inherited sex-linked form of mental retardation. It occurs in approximately 1/1,000 live births and affects both males and females. What is of considerable interest is that a significant number of these children, in addition to a variety of physical, cognitive and behavioral difficulties, also have disturbances of sensory integration function which can, and do, severely effect their behavior and capacity to learn and function in their families and communities.
