Autism

Abnormal brain growth and function are features of autism, an increasingly

common developmental disorder that now affects 1 in 60 boys in the US. Now

researchers from the University of Pittsburgh and Thoughtful House Center for

Children in Austin, Texas, have found remarkably similar brain changes to those

seen in autism in infant monkeys receiving the vaccine schedule used in the

1990’s that contained the mercury-based preservative thimerosal.

 

The group’s findings were published yesterday in the journal Acta

Neurobiologiae Experimentalis. They used scanning techniques that assessed

both brain growth and brain function in the same animals over time. The research

team was able to see differences in the way the brains of vaccinated and

unvaccinated animals developed. Scans were performed before and after the

administration of primary MMR and DTaP/Hib boosters that were given at the human

equivalent of 12 months of age.

 

Throughout the study period, vaccinated animals showed an increase in total

brain volume – a feature of the brain in many young children with autism -

when

compared with unvaccinated animals.  However, a specific part of the brain

associated with emotional responses that is thought to be important in autism,

the amygdala, did not show abnormalities until after the 12-month vaccines had

been given. In addition, after the 12-month vaccines only, the functional brain

scans showed significant differences between vaccinated and unvaccinated groups.

These functional scans looked at the activity of receptors for morphine-like

compounds (opioids) that may play a role in the brain of children affected by

autism. Vaccine administration was associated with an increase in opioid binding

activity in the amygdala compared with a decrease in the unvaccinated group.

 

The results indicate that multiple vaccine exposures during the previous 3-4

months may have had a significant impact on brain growth and development in ways

that are consistent with the published data on autism. For the amygdala, the

novel findings of abnormal growth and function appear to be a function of more

recent vaccine exposures - the 12-month primary MMR vaccine and the DTaP and Hib

boosters.

 

In an accompanying editorial Dr. Kris Turlejski, the Editor-in-Chief,

described the findings as “alarmingâ€, “support[ing] the possibility that

there

is a link between early immunization and the etiology of autism.â€

 

In the same primate model, the research team has already identified delayed

acquisition of vital brainstem reflexes in infants exposed to the

thimerosal-containi ng hepatitis B vaccine on the first day of life, compared

with unvaccinated animals. A larger, second phase study is currently underway to

see if these findings can be replicated.

 

Dr. Wakefield, who is not a listed author but

whose support in the design of the study is acknowledged, said “I hope

the model will not only provide important insights into the origins of autism,

but also ways of safely testing possible new autism treatments and

vaccines.â€
