Sensory integration disorder or dysfunction (SID) / Sensory Processing disorder (SPD) is a neurological disorder that results
from the brain's inability to integrate, process, and respond to certain information received from the body's five basic sensory
systems. These sensory systems are responsible for detecting sights, sounds, smell, tastes, temperatures, pain and the position
and movements of the body. The brain then forms a combined picture of this information in order for the body to make sense of
its surroundings and react to them appropriately. The ongoing relationship between behavior and brain functioning is called
sensory integration (SI). Sensory integration provides a crucial foundation for later, more complex learning and behavior.
Sensory experiences include touch, movement, body awareness, sight, sound, smell, taste, and the pull of gravity. Distinguishing
between these is the process of sensory integration (SI). While the process of sensory integration occurs automatically and
without effort for most, for some the process is inefficient. Extensive effort and attention are required in these individuals for
sensory integration to occur, without a guarantee of it being accomplished. When this happens, goals are not easily completed,
resulting in sensory integration disorder (SID) / sensory processing disorder (SPD).
