Sounds can be terrifying to them; tastes and smells can make them vomit; bright lights can be unbearable; and textures can cause great pain. Sensory processing disorders are caused by the brain’s inability to respond properly to stimuli affecting the five senses. People with an undiagnosed disorder may be hypersensitive, whiny, anxious, finicky, or even become sick to their stomach. They may react dramatically to sensory stimulation, such as bright lights, or be unresponsive and not react to sensations such as hot and cold.
