    In this parent-observed study, we tested the administration of intranasal OT for 10 weeks (phase 1), followed by a combination of intranasal OT and NAL for 38 weeks (phase 2) in a 13-year-old male with confirmed hypothalamic obesity and hyperphagia post-CP resection.

    In a boy with hypothalamic obesity, hyperphagia was reduced during oxytocin alone (phase 1); the abstract states this jointly for phases 1 and 2.

    In plain wordsIn one boy, excessive eating was reduced while he took oxytocin alone; the report also covers the later phase with naltrexone.
