**Question:** Persistent Moro's reflex at 6–7 months indicates –

**Core Concept:** Moro's reflex is a primitive reflex that occurs in infants during the early developmental stages, characterized by rapid arm and leg extension in response to sudden loss of support. This reflex usually regresses around 6-7 months of age as the child develops more complex motor skills and cognitive abilities.

**Why the Correct Answer is Right:** Persistent Moro's reflex at 6-7 months indicates a delay in the normal developmental progression of motor skills and cognitive abilities in infants. This can be a sign of an underlying neurological condition or developmental delay that requires further evaluation and intervention.

**Why Each Wrong Option is Incorrect:**

A. This option is incorrect because a normal regression of Moro's reflex occurs in the expected age range (6-7 months).
B. This option is incorrect as the correct answer explains the importance of evaluating a persistent reflex at that age.
C. This option is incorrect because it does not address the development issue highlighted by the persistent Moro's reflex.
D. This option is incorrect as it does not focus on the developmental concerns associated with a persistent Moro's reflex at 6-7 months.

**Clinical Pearl:** A persistent Moro's reflex at 6-7 months should raise suspicion for developmental concerns and prompt a thorough developmental and neurological evaluation, including a detailed assessment of the child's motor skills, cognitive abilities, and other possible underlying causes. Early identification and intervention can significantly improve the child's outcomes and overall development.

**Correct Answer:** C. Persistent Moro's reflex at 6-7 months indicates developmental concerns and should prompt further evaluation.
