A woman died of a rare neurological disease whose son had been infected when he was fetal only while pregnant with him decades ago.
The fetus transmitted the rare disease of Creutzfeldt-Jakob to his mother, who took all these years to develop.
The adult is now born with a rare genetic damage that causes the brain, which in turn causes a reduction in functions and mental movements.
He inherited his father's pathology, who died years ago. However, what surprises doctors is that the woman, who died at age 70, did not suffer changes in their genes, but died in a similar way.
The experts concluded that the mother had been infected with the disease due to her son during the pregnancy process since fetal cells went to the placenta and traveled through the body to reach her brain.
The doctor and researcher at the University of Copenahague who are responsible for the case, Ausrine Arekeviciute, explained that when women are pregnant, fetal cells travel through the plaque across the body and can reach different organs of the mother.
Today the son is still alive although the disease is affecting it.
Only the doctor's medical diagnosis did the doctors suspect that his mother, who had no genetic mutation associated with the disorder, could not be infected by his own son .
"There are no treatments and not the prognosis good," said doctor Ausrine Arekeviciute. "It's a sad story," he said. The case was published in the Journal of Neuropathology and Experimental Neurology.
Creutzfeldt-Jakob disease can occur spontaneously, either electronically or transmitted by contacting infected tissue, for example, during a transplant or by eating contaminated meat.
