Question

Quizplus · Accepted Answer

Multiple studies have indicated that there are multiple genetic factors involved in the development of autism. However, there is no conclusive evidence linking autism with vaccines or a single malfunctioning gene variant. While some studies suggest an enlarged prefrontal cortex in autistic individuals, this finding is not consistent across all studies and is not a proven causal factor in the disorder.
