Birth defects and heart problems are showing up not only in the children, but the grandchildren of veterans who served in America's military during the Vietnam War.
The question is whether Agent Orange, a powerful poison sprayed by the military to wipe out vegetation, is a contributing factor.
Emma Ackerson, 9, of Holiday, looks like any other little girl playing her with dog.
But this list of Emma's medical problems keeps growing:
Connective tissue disorder, which is EDS ( Ehlers Danlos syndrome), Hypermobility, Vision problems, Muscle weakness, Sleep apnea, Epilepsy (benign occipital epilepsy), Orthostatic hypotension, Dysautonomia, Long QT syndrome, Joint pain, GI problems, Migraines, Acid reflux, Arrhythmias, Balance problems.
Emma suffers headaches and stomach pain, as well as heart problems.
"All of a sudden she gets pale. She gets dark circles under her eyes and you either have to lay her down on the floor, you have top pick her up, because she'll pass out," explained Emma's mother, Keri Ackerson.
According to her mom, Emma's problems stem from a birth defect called Chiari malformation, a neural tube defect.
"It's a structural defect in the brain where part of the brain is going down in to the spinal column," said Keri.
Chiari malformation is also a condition associated with Agent Orange.
