The main symptom of sensory processing disorder is oversensitivity or lack of responsiveness to an environmental stimulus, affecting one or multiple senses, explains WebMD. Patients may lack coordination, be difficult to converse or play with, bump into things, and not know the position of their limbs.
Some patients with sensory processing disorder yell if someone touches them or retreat in fear from certain food textures. Others fail to react to extreme temperatures or pain. Although children are typically identified as having sensory processing disorder, adults can show symptoms, notes WebMD. Medical professionals diagnose the disorder when symptoms are severe enough to interrupt normal daily activities.
