Which symptom is associated with neonatal abstinence syndrome?

The symptom associated with neonatal abstinence syndrome (NAS) is a high-pitched cry. NAS occurs in newborns who have been exposed to addictive substances, typically opioids, during pregnancy. One of the hallmark signs of this syndrome is a distinct high-pitched or shrill cry, which is often an indicator that the infant is experiencing withdrawal symptoms.

This high-pitched cry can be a reflection of the infant's discomfort and irritation as they adjust to being away from the substances they were exposed to in utero. Other common symptoms of NAS include jitteriness, increased muscle tone, irritability, feeding difficulties, and gastrointestinal issues, but the high-pitched cry is particularly recognized and noted by healthcare providers.

While low birth weight, continuous coughing, and fever can be related to various other neonatal conditions and complications, they are not specific indicators of NAS.
