Regression and a previously normal visit
A fictional toddler previously used several meaningful words and gestured to communicate interest. The caregivers now report loss of those words, less response to the name and a change in social interaction. The child had a reassuring routine visit several months earlier. A trainee says that the earlier result proves there is no need for further assessment until school age. The supervising clinician explains that development is a trajectory and asks about hearing, vision, illnesses, motor skills and the wider developmental pattern. The case does not provide enough information to diagnose one specific neurodevelopmental disorder. It tests recognition that loss of acquired function differs from a single isolated variation in milestone timing.
1. Why does the earlier visit not settle the case?
Read the worked answer
A previously reassuring assessment does not exclude a subsequent change. Loss of acquired skills is a new finding that needs timely assessment.
2. What should the evaluation avoid?
Read the worked answer
Do not assign a definitive diagnosis from one reported behavior or ignore relevant hearing, neurological, medical and developmental assessment.
