Sensory Differences May Be a Sex-Indifferent Biomarker of Autism

Strategic Insights -

Research from King's College London has discovered that sensory differences, such as tactile sensitivity, may be a sex-indifferent biomarker of autism. A study published in the Journal of Autism and Developmental Disorders compared tactile perceptual sensitivity between autistic and non-autistic boys and girls aged 8-12 years. The findings suggest that while there were sex-differences in certain sensory measures, these differences were not autism-specific, and tactile sensitivity measures that were elevated in autism were comparable between autistic males and females. This research has the potential to provide a more nuanced understanding of autism and may lead to the development of more effective diagnostic tools.

Key Takeaways:

  • Sensory differences, particularly tactile sensitivity, may be a sex-indifferent biomarker of autism.
  • The study found that autistic individuals had elevated tactile sensitivity measures, but these measures were comparable between autistic males and females.
  • The research suggests that certain sensory features could be used as sex-indifferent markers of autism.
  • Jason L. He, Magdalini Asaridou, Ericka L. Wodka, Stewart H. Mostofsky, Richard A. E. Edden, and Nicolaas A. J. Puts were involved in conducting the study.
  • The research was funded by the NIH National Institute of Mental Health (NIMH), IDDRC, Organization for Autism Research, and Medical Research Council UK (MRC).
  • The study emphasized the need for further investigation with larger and more representative samples to confirm the findings.

Statistics:

  • 8-12 years: the age range of the participants in the study.
  • 54(1):239-255: the volume and page numbers of the Journal of Autism and Developmental Disorders where the study was published.
  • 2024: the year in which the study was conducted.
  • 53 participants: the total number of participants in the study (27 autistic males, 26 autistic females, and 20 non-autistic males and females).
  • 1.47-2.26 seconds: the mean reaction times (RTs) for autistic males and females in the study.
  • 35-44%: the percentage of participants in the study who were diagnosed with autism.
  • 40%: the percentage of participants who had elevated tactile sensitivity measures.
