What does a persistent Moro reflex in an infant suggest?

A persistent Moro reflex in an infant suggests potential neurological concerns, such as the possibility of cerebral palsy. The Moro reflex, also known as the startle reflex, is a normal part of infant development, typically observed in newborns and diminishing over the first few months of life. If this reflex persists beyond the expected time frame, it may indicate underlying neurological issues.

In cases of cerebral palsy, the infant may exhibit abnormal muscle tone, motor function difficulties, or other developmental delays. The sustained presence of the reflex beyond six months could signal that the infant’s neurodevelopment is not progressing typically, prompting further examination and possibly indicating a risk for conditions like cerebral palsy.

While the Moro reflex is a normal reflex response in a newborn, its persistence hints at a deviation from normal developmental milestones, which is the reason why it’s an important indicator for pediatricians monitoring an infant’s growth and neurological health.
