Sensory

Many children with Fragile X are sensitive to certain sensations. They may become frantic at the sound of a loud noise or may be easily distracted by slight sounds in the room. They may be bothered by the texture of their clothes against their skin, or they may be unable to focus on the parts of their environment that are important, such as the sound of the teacher’s voice. Infants with Fragile X may have problems drinking from a bottle, perhaps because the feel of the nipple upsets them. Some children try to avoid being touched, and even a brief tickle or hug may be overwhelming. Even though many of these symptoms are often life-long, most people affected by Fragile X, with the proper intervention, can find ways to handle or avoid the discomfort. (See the Are there treatments for Fragile X syndrome? section for more information.)

Children with Fragile X may also have problems with balance. A sense of balance helps keep the body upright and stable. Problems with balance, coordination, and connective tissue can cause difficulties for children with Fragile X as they learn to sit, stand, and walk, or later, to ride a bike. Even so, most children with Fragile X learn to do these tasks.
