The startle reflex usually goes away by the time baby is 2 to 4 months old. 1988; 43 (1):35-37. Because it triggers the . The startle response originates from the brainstem and is treated with clonazepam. Neonatal abstinence syndrome resulting from the mother's prescription medication was the underlying etiology. 1. . Although genetic testing can be helpful for elucidating the subtype, it does not affect the management. "When a baby is impacted by the Moro reflex, swaddling is a very effective way to keep the baby calm," Kouri says. Little startle noises made them jumpy, these are the babies. Now, people wouldn't dare because they might get hit. The seizures (or spasms) make muscles in the arms and legs stiff and bend the baby's head forward. The genetic basis is a mutation usually of the arginine residue 271 leading to neuronal hyperexcitability by impairing glycinergic inhibition.
