According to a study by University of Washington researchers, diagnostic ultrasound in the first trimester of pregnancy is linked to increased autism severity in the child.
The study, published in Autism Research, was based on a three-step model. The fist part studied genetic vulnerability to autism, followed by studies on outside stressors and the time of stress.
The researchers now plan to look into the possibility of ultrasound being a cause for autism in children.
Questions to think about:
- Does the study provide reason for stricter guidelines?
- What could be the genetic reasons for autism triggered by ultrasound?
- Could the practice of ultrasound be linked with other disorders?
