NEUROPSYCHOMOTOR AND COGNITIVE DEVELOPMENT OF PRESCHOOLERS BETWEEN 24 MONTHS AND 48 MONTHS OF LIFE EXPOSED TO THE ZIKA VIRUS DURING PREGNANCY
Abstract
This study addresses the neuropsychomotor development of children who suffered the intrauterine exposure
to the Zika vírus, ZIKV, highlighting manifestations, test results, and relevant clinical implications. It aimed to evaluate and describe the neurological manifestations and neuropsychomotor development of children who suffered the intrauterine exposure to ZIKV throughout their lives by a longitudinal observational study that
followed the development of 45 children who were vertically exposed to ZIKV and aged from 24 to 48 months in a tertiary hospital in Niterói, Brazil. This research was registered at CEP under CAE 62992016.9.0000.5243.
These children were divided into 26 confirmed cases with RT-qPCR of the Zika vírus and 19 likely cases. During follow-up, tests such as the Denver II and SON-R were conducted to evaluate neuropsychomotor and cognitive development, respectively. The results were compared with patterns of development typical for age. Moreover, the neurological manifestations observed over time were recorded, especially regarding microcephaly and the history of exanthem during gestation. The analysis of the data found correlations between exposure to the
Zika vírus, neurological manifestations, and neuropsychomotor development of children, providing clinical foundations to the current literature regarding good neurodevelopment prognosis of nonmicrocephalous children exposed to the ZIKV and subsidizing the importance of early diagnosis for care awareness and
long-term clinical follow-up.
