Sensory Processing Disorder (SPD) is the newest term for, and is used synonymously with, Sensory Integration Disorder, Sensory Integration Dysfunction (SI Dysfunction) and Dysfunction in Sensory Integration (DSI).
What is Sensory Processing Disorder?
Definition of SPD. Sensory processing refers to the way the nervous system receives messages from the senses and turns them into responses. For those with Sensory Processing Disorder, sensory information goes into the brain but does not get organized into appropriate responses.
Sensory integration is a normal, neurological, developmental process which begins in the womb and continues throughout one’s life. Although, it is important to note, the most influential developmental time is in the first seven years of life. Sensory processing is the process by which the brain takes in sensory input and interprets this information for use.
