A report released on Tuesday shows in graphic detail the kind of damage Zika infections can do to the developing brain - damage that goes well beyond the devastating birth defect known as microcephaly, in which the baby's head is smaller than normal.
The current Zika outbreak was first detected last year in Brazil, where the virus has been linked to more than 1,800 cases of microcephaly, which can cause severe developmental problems.
Prior research has shown the Zika virus attacks neural progenitor cells - a type of stem cell that develops into different types of nerve or brain cells.
The latest research, published in the journal Radiology, draws from imaging and autopsy findings linked with confirmed Zika infections done on 17 infants and fetuses cared for at the Instituto de Pesquisa, in Campina Grande in the state of Paraiba in northeastern Brazil, where the infection has been especially severe.

Yale team discovers how Zika virus causes fetal brain damage

Infection by the Zika virus diverts a key protein necessary for neural cell division in the developing human fetus, thereby causing the birth defect microcephaly, a team of Yale scientists reported Aug. 24 in the journal Cell Reports.
The findings suggest that Zika virus might be susceptible to existing antiviral drugs that may prevent disruption to the developing nervous system, said the researchers.

In some genetic cases of microcephaly, stem cells fail to launch
scienmag.com - August 24, 2016
In a very severe, genetic form of microcephaly, stem cells in the brain fail to divide, according to a new Columbia University Medical Center study that may provide important clues to understanding how the Zika virus affects the developing brain.
The study was published August 24 in Nature Communications.
