In his response to your question, Sheikh `Abdul-Majeed Subh, a prominent Azhar scholar, states:
The Prophet (peace and blessings be upon him) is reported to have said, “The pen has been raised for three persons [meaning they are not held accountable for what they do]: one who is sleeping until he wakens, a child until he reaches the age of puberty, and an insane person until he becomes sane” (Ahmad, Abu Dawud, At-Tirmidhi, An-Nasa’i, Ibn Majah, and Al-Hakim).
Almighty Allah knows best.
