Study suggests link between autism, pain sensitivity
Quote:
New research by a UT Dallas neuroscientist has established a link between autism spectrum disorder (ASD) and pain sensitivity.
The study, led by Dr. Xiaosi Gu, outlines alternations in pain perception faced by people on the autism spectrum and how those changes can affect them in social functions.
Gu said there were three main findings from the study:
It confirmed that people with ASD are hypersensitive to pain, a finding that has been documented in previous studies.
In a new finding, the study showed that when people with ASD anticipate painful stimulus, their brains generate greater neural responses in the ACC, compared to those without ASD.
In addition, the research indicated that the more brain activity the participants show during pain anticipation, the less they score on an empathy quotient questionnaire. Gu said people with autism often are poor at empathy, which is the ability to understand what another person may be feeling. This result indicates that pain anticipation is related to social impairments faced by those with autism.
She said that a withdrawal from interactions may be a way of protecting oneself.
"The risks of encountering pain are part of daily life and are normal for non-ASD individuals, but may be overwhelming for autistic people," Gu said. "Therefore, one possible explanation of our finding is that to protect themselves, individuals with ASD may not engage in social interactions as much. You reduce the risk of encountering pain or other sensory experiences that are very normal for non-ASD individuals, but not for those with ASD."
