Sensory Issues are commonly seen in the children with AUTISM. They often get an diagnosis of Sensory Integration Disorders as they have dysfunctional sensory system. Sometimes one or more senses are either over- or under-reactive to stimulation.Such sensory problems may be the underlying reason for such behaviors as rocking, spinning, and hand-flapping. Although the receptors for the senses are located in the peripheral nervous system (which includes everything but the brain and spinal cord), it is believed that the problem stems from neurological dysfunction in the central nervous system–the brain. As described by individuals with autism, sensory integration techniques, such as pressure-touch can facilitate attention and awareness, and reduce overall arousal. Temple Grandin, in her descriptive book, Emergence: Labeled Autistic, relates the distress and relief of her sensory experiences.
