The dramatic rise in autism prevalence over the past few decades is nothing short of alarming.
What exactly is autism? I ask this because when I was a child, it was so rare that none of us had ever heard of or known anyone with it.The Autism Speaks website defines autism thus:
Autism, or autism spectrum disorder (ASD), refers to a broad range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication.
A few decades ago, autism was rare, but then it rose meteorically. “Reported rates of autism in the United States increased from < 3 per 10,000 children in the 1970s to > 30 per 10,000 children in the 1990s, a 10-fold increase.”
Since the 1990s, we have seen another tenfold increase. According to the Centers for Disease Control, autism affects an estimated 1 in 31 children and 1 in 45 adults in the United States today.
In just two generations, the prevalence of autism has risen 100-fold. Was there a similar explosion for any other medical or public health condition?
Can this 1,000 percent increase be explained by genetics, as some doctors suggest?
A 100-fold increase in two generations—roughly 40 years—defies the principles of genetic evolution, which operates on timescales spanning centuries, not decades. This unprecedented rise points to environmental factors, including food additives, medicines, vaccines, and other toxins, as the primary drivers of the autism epidemic.
Genetics likely plays some role in autism. Twin studies suggest that autism’s heritability ranges from 60% to 90%, indicating a strong genetic component.
However, genetic changes do not occur quickly enough to explain a 100-fold increase in prevalence within two generations, only two reproductive cycles.
Evolution through genetic mutation and natural selection is a gradual process that often requires thousands of years to produce significant changes at the population level.
No one would attribute the increase in obesity, diabetes, and other chronic diseases over the past few decades to genetics instead of environmental factors like diet and exercise. Autism is exhibiting a similar trend.
