Researchers say they’ve found clear and direct evidence that autism begins during prenatal brain development. Video courtesy UC-San Diego Health System.
All I can say is "wow". This type of research was done years ago looking at dyslexia which revealed many problems with development of the brain in the areas needed for phonemic and phonologic awareness (awareness of sounds in language and how they can manipulate sounds to communicate information.
I look forward to further research on this to reinforce the need to address red flag signs early.
