What is sensory system dysfunction?
Sensory system dysfunction occurs when the body is not registering, processing, or modulating sensory input normally, leading to misinterpretations of their body and surroundings. This means that the brain is not receiving, understanding, and using the information that is coming in from the environment and the body correctly. A child’s sensory system may be over -stimulated or under-stimulated due to their inability to continuously modulate the incoming sensory experiences needed to function and learn. A child can have one or more sensory systems that are over-sensitive or under-sensitive to certain inputs.Under-sensitive (sensory seeking):Over-sensitive (aversive or fright, flight, or fight responses):Sensory Defensiveness:Tactile System Dysfunction: Tactile Defensiveness is an over-sensitivity of the protective touch systems.
