Autism is generally considered to be present from birth, meaning people are born with the genetic traits that increase their likelihood of having autism. Scientific consensus indicates autism roots during early fetal brain development, with about 80% of autism cases linked to genetic factors. Signs of autism may not always be obvious immediately at birth but tend to emerge as the child grows. Environmental factors during pregnancy and early childhood can influence how autism manifests but do not cause autism by themselves. Autism is not developed later in life and is not linked to postnatal influences like vaccines or toxins. It is a neurodevelopmental condition that lasts throughout life.
