Altered tactile sense

The social impairments and high anxiety seen in people with autism or related disorders may be partly due to a disruption in the nerves of the skin that sense touch, a new study in mice suggests. (…) A majority of people with autism spectrum disorders also have an altered tactile sense; they are often hypersensitive to light touch. (…) They tend to be very wary of social touch [like a hug or handshake], or if they go outside and feel a gust of wind, it can be very unnerving. (…) The finding that dysfunction in the touch system can contribute to behavioral problems is exciting. (…) It gives you a sense of how fundamental these sensory features might be.
