Sensory sensitivity to noise, lights, crowds, or touch can cause children and adults who have sensory processing disorders to become confused and frightened. The overloaded senses may lead to reactions that parents perceive as behavior problems when they are really just signs of sensory overload.
Sensory meltdowns are not social interactions like tantrums. The child rarely cares whether anyone pays him or her attention. The meltdown is also unlikely to disappear as soon as the want is met. Instead, it will subside after the offensive stimulus has been removed.
