Is there a Quranic recitation or a Prophetic hadith for healing a child afflicted with Down syndrome?

The Quran is a healing and a mercy. Allah has sent down a cure for every ailment. The entire Quran is a healing and guidance, and Allah guides some of His servants to specific verses for the healing of a particular illness, based on what has been authentically reported from the Prophet (peace and blessings be upon him) and the righteous predecessors. No specific verses or hadiths have been reported for the ruqyah (exorcism/healing recitation) of the mentioned illness. Therefore, the patient's family should seek treatment and recite upon him what is easy from the Quran, such as Al-Fatiha, Ayatul Kursi, the concluding verses of Surat Al-Baqarah, and Al-Ikhlas and the two Mu'awwidhatayn (Al-Falaq and An-Nas).
