Has ever a lunatic locked up in a insane asylum/psych ward converted to Christianity after having their soundness of mind miraculously restored?

Are there any published testimonies of individuals that were sent to [lunatic asylums](https://en.wikipedia.org/wiki/Lunatic_asylum) or [psychiatric wards](https://en.wikipedia.org/wiki/Psychiatric_hospital) as "lost causes" due to severe mental illness, that eventually converted to Christianity after having their soundness of mind miraculously restored? Or in simpler terms: has ever a lunatic in an insane asylum/psych ward had an unexpected spontaneous recovery that led to their conversion to Christianity?
