https://i.ytimg.com/vi/gwTx2SEAFxY/mqdefault.jpg 10/21/2026 10:20:37 A 4½-year-old boy develops sudden, ascending weakness of both lower limbs over 7 days, followed by breathing difficulty. He has hypotonia, absent deep tendon reflexes, power of 2/5 in the lower limbs and 3/5 in the upper limbs, diaphragmatic weakness, and absent superficial reflexes. Over the next 7 days his power improves, his breathing is fine, and he can sit and walk with support. But his reflexes have still not returned, and his nerve conduction study is normal.
