Which developmental features are commonly associated with Prader-Willi?

• A. Delayed development, learning disability, delayed puberty
• B. Rapid development and early puberty
• C. Normal development in most areas
• D. No speech delay

Answer: (A)

Prader-Willi syndrome commonly shows developmental delays from infancy, learning difficulties in childhood, and delayed puberty due to hypogonadism. Infants often have low muscle tone and slow motor milestones, which contribute to overall developmental lag. This combination—delayed development, learning challenges, and delayed puberty—fits the typical pattern seen in Prader-Willi. The other possibilities don’t align with this profile: rapid development or early puberty contradicts the known hypotonia and later pubertal issues; normal development isn’t characteristic; and speech delay is a common part of Prader-Willi, so saying there’s no speech delay isn’t accurate.
