Multiple sensory hypersensitivity - "Sensory Modulation Disorder" and the Important Points that Otolaryngologists should know

In patients presenting with the chief complaint of hyperacusis, we examined for the presence of hypersensitivity symptoms of other sensory organs using two questionnaires, namely, Khalfa hyperacusis and sensory profile, and identified 5 cases of multiple sensory hypersensitivity; their clinical features are reported here. There were 5 cases of visual hypersensitivity and 4 cases of tactile hypersensitivity. We considered that the multiple sensory hypersensitivity was attributable to a sensory modulation disorder of the central nervous system. No specific tests, diagnostic methods or treatments for sensory hypersensitivity have been established yet and further studies are required.
