Sensory Processing Disorder (SPD) is defined as a neurological disorder that results from the brain’s inability to integrate certain information received from the bodies 7 sensory systems (tactile, visual, auditory, olfactory, taste, vestibular, proprioceptive). These systems are responsible for detecting and registering sights, sounds, smells, tastes, temperatures, pain, and the positions and movement of the body. From this information, the brain forms a combined picture of its surroundings and reacts to them appropriately. All sensory systems work together to help people learn, to attend, read, write, do math, participate in motor activities, and participate in daily activities. Taking in sensory information in an accurate manner, elicits a functional adaptive motor or behavioral response. The ongoing relationship between behavior and brain functioning as it relates to interpreting sensory information if referred to as sensory integration (SI). This process occurs automatically, unconsciously, and without effort for most people. For others, the process is inefficient or incomplete, and requires extensive effort and attention for sensory integration to occur. SPD can effect level of arousal, attention, emotional behavior, social relationships, as well as motor skill functioning. Hypersensitivity can elicit a “fight” or “flight” response, and hyposensitivity can elicit not enough engagement to be successful developmentally or with various tasks.
