A recent US research has found the presence of additional brain cells in autistic children especially in an important area in the brain in charge of communication and emotional development.
Researchers found close to 67% increase in the number of brain cells in the prefrontal cortex. This may also explain the reason for autistic children to have bigger sized brains as compared to normal children.
Autism may have well begun during the development of the child in the womb, more-so during the second trimester of pregnancy when the prefrontal cortex begins to develop.
The prefrontal cortex in the brain deals with language and communication. It also facilitates mood, social ability and attention. Autistic children are found to portray some trouble in these areas.
