Is Surat Ya-Sin a cure for forgetfulness?

There is no specific virtue for Surat Ya-Sin in treating forgetfulness. However, one can supplicate and ask Allah for all needs through the entire Qur'an, as the Prophet, peace and blessings be upon him, said: "Whoever recites the Qur'an, let him ask Allah by it." There is also a weak hadith stating that reciting Surat Ya-Sin at the beginning of the day fulfills needs.
