How do Sensory Processing Problems Affect Behavior? Both males and females with fragile X syndrome are often reported as having behavioral issues related to sensory processing disorders. Sensory integration problems have been noticed even in very young children with fragile X. Parents may notice the infant's hypersensitivity to light, sounds, touch, and textures. Some young children may show tactile defensiveness, with strong negative reactions to being held or to certain textures of clothing. High arousal levels to visually complex or crowded environments, unpredictable events, and maintenance of eye contact are also common. Each of these areas may affect behavior. Hypersensitivity and difficulty in modulating arousal may cause overreactions to highly stimulating situations, changes in routine, or demands for interaction. Self-stimulation, such as hand flapping, rocking, or biting the skin, clothing, or objects, may result. Acting out, with temper tantrums or hitting, may also be the consequence of an over stimulating situation.
Many undesirable behaviors shown by persons with fragile X syndrome can be controlled by a combination of medication and environmental changes. See Working with Difficult Behaviors, Medication, Sensory Integration Characteristics, and Intervention for Sensory Integration Disorders. Gail Harris-Schmidt, Ph.D., CCC-SLP |
Problems with eye gaze are another result of sensory processing overload. The demand for direct eye contact,
along with conversation, is too much for many persons with fragile X syndrome. Even when interacting with their parents, some children with fragile X turn away from direct eye gaze. |
