Tick Tock Autism Clock

The biological clock ticks away as parent’s age is linked to autism.

Scientific journal, Autism Research, recently published a study linking parent’s ages to autism. The researchers were based at the University of California, Davis where they analyzed five million births of the 12,159 cases of autism discovered during the 1990s in California.

The new study suggested that as the birthing age for women increases by 5 years, her risk of having an autistic child increased as well. The research specifies that women under 25 have the lowest risk, while women 40 years old have a 77 percent higher risk.

Contrary to prior studies, this new research also dispels the belief that the mothers’ age is solely responsible for producing autism in children. The autism research also found that fathers play an important part in predicting autism. By analyzing men, the study found men over 40 who had children with women under 30 had a 59 percent chance of having autistic children.

The lead author of the paper, Janie F. Shelton, reinforced these facts about the research “we can’t say that the shifting trend of maternal age is responsible for the increased rates of autism.”

By targeting the mother and father’s age, this information also provides clues to how we can finally find the cause of autism. Because older parents may use fertility treatments in addition to being exposed to a wider variety of substances over time, it provides another hint in curing autism.

    This is stupid. Autism affects 1 in 90 & the ages of the parents are all across the board. Some are teens, some young adults, some older adults, some middle age adults.
