Zika Attacks and Destroys Parts of Babies’ Brains

The images tell a heartbreaking story: Zika’s calamitous attack on the brains of babies — as seen from the inside.

With a macabre catalog of brain scans and ultrasound pictures, a new study details the devastation done to 45 Brazilian babies whose mothers were infected with Zika during pregnancy. The study, published Tuesday in the journal Radiology, is the most comprehensive collection of such images so far, and it reveals a virus that can launch assaults beyond microcephaly, the condition of unusually small heads that has become the sinister signature of Zika.

Most of the babies in the study were born with microcephaly, but many of them also suffered other impairments, including damage to important parts of the brain: the corpus callosum, which connects the two hemispheres of the brain; the cerebellum, which plays a significant role in movement, balance and speech; the basal ganglia, which are involved in thinking and emotion.

“It’s not just the small brain, it’s that there’s a lot more damage,” said Dr. Deborah Levine, an author of the study and a professor of radiology at Harvard Medical School in Boston. “The abnormalities that we see in the brain suggest a very early disruption of the brain development process.”
