Children with autism and other developmental disabilities often have sensory integration dysfunction. However, sensory integration dysfunction can also be associated with premature birth, brain injury, learning disorders, and other conditions.
The exact cause of sensory integration dysfunction is not known. It is commonly seen in people with autism, Asperger's syndrome, and other developmental disabilities. Most research suggests that people with autism have irregular brain function. More study is needed to determine the cause of these irregularities, but current research indicates they can be inherited.
Children with sensory integration dysfunction cannot properly process sensory stimulation from the outside world. Your child may:
A health professional, often an occupational or physical therapist, will evaluate your child by observing his or her responses to sensory stimulation, posture, balance, coordination, and eye movements. While many children have a few of the symptoms described above, your health professional will look for a pattern of behavior when diagnosing sensory integration dysfunction.
Sensory integration therapy, usually conducted by an occupational or physical therapist, is often recommended for children with sensory integration dysfunction. It focuses on activities that challenge the child with sensory input. The therapist then helps the child respond appropriately to this sensory stimulus.
Therapy might include applying deep touch pressure to a child's skin with the goal of allowing him or her to become more used to and process being touched. Also, play such as tug-of-war or with heavy objects, such as a medicine ball, can help increase a child's awareness of her or his own body in space and how it relates to other people.
Although it has not been widely studied, many therapists have found that sensory integration therapy improves problem behaviors.
