Mitochondrial Disorders Implicated

health agencies, including the Food and Drug Administration, the Centers for Disease Control and Prevention, and the National Institutes of Health, met in Indianapolis Sunday to discuss whether cellular diseases known as mitochondrial disorders should be considered in research on autism.

Mitochondrial disorder vaccinations could possibly cause autism.At the heart of the issue for many specialists and concerned parents is whether vaccines -- suspected by some people as being a cause of autism -- might trigger mitochondrial disorders, which lead to autism.

One of the people at the meeting in Indianapolis was Jon Poling, father of 9-year old Hannah Poling, who was diagnosed with autism after receiving a series of vaccines.

Poling, who is also a neurologist, said he believes the vaccines may have aggravated a pre-existing condition, called mitochondrial disease, which in turn, led to Hannah's autism.

Some hope that this meeting will generate more research.

"I guess I kind of feel like it's Christmas Eve," Poling said. "Tomorrow is Christmas morning and, hopefully, those presents will be grants in the form of serious federal monies to look into autism and its relationship to mitochondrial disorders."

Doctors said perhaps 5 percent to 10 percent of patients with mitochondrial disorders show symptoms of autism.


"Parents have observed a time association between when their child got vaccinated and when they had a worsening of their clinical state," said Dr. Douglas Wallace, director of the Center for Molecular and Mitochondrial Medicine and Genetics at the University of California-Irvine. "But just because two things occur at the same time, it doesn't mean that one caused the other."

While many mitochondria specialists said they are excited to study this potential link, they also said there is no evidence that vaccines play a major role in causing autism, as many parents of autistic children suspect.

Dr. Bruce Cohen, a neurologist at the Cleveland Clinic, has weighed the possible link and said the issue is complicated.

"I think there is some potential of causing undue concern when one hears about situations such as the Hannah Poling case," Cohen said. "But when we look at all the benefits of the vaccine program in preventing horrible diseases and horrible deaths, I think you have to take it all into consideration."
