Though the findings did not reach significance, infants in this subgroup tended to have a lower WIDEA mobility z-scores (P = .054) and lower AIMS scores (P = .26) than the Zika-exposed infants with normal cranial ultrasounds.
“Mild nonspecific cranial ultrasound findings may represent a mild injury” related to exposure to their mother’s Zika infection during pregnancy, the researchers suggested. “It may be a risk factor for the lower mobility outcome,” Dr. Mulkey said.
The researchers hope to continue later follow-ups as the children age.
The research was funded by the Thrasher Research Fund. Dr. Mulkey had no conflicts of interest.
