Ohio Rev. Code § 4731.221
If the state medical board has reason to believe that any person who has been granted a license or certificate under this chapter is mentally ill or mentally incompetent, it may file in the probate court of the county in which such person has a legal residence an affidavit in the form prescribed in section 5122.11 of the Revised Code and signed by the board secretary or a member of the board secretary's staff, whereupon the same proceedings shall be had as provided in Chapter 5122. of the Revised Code. The attorney general may represent the board in any proceeding commenced under this section.
If any person who has been granted a license or certificate under this chapter is adjudged by a probate court to be mentally ill or mentally incompetent, the person's license or certificate shall be automatically suspended until such person has filed with the state medical board a certified copy of an adjudication by a probate court of the person's subsequent restoration to competency or has submitted to such board proof, satisfactory to the board, that the person has been discharged as having a restoration to competency in the manner and form provided in section 5122.38 of the Revised Code. The judge of such court shall forthwith notify the state medical board of an adjudication of mental illness or mental incompetence, and shall note any suspension of a license or certificate in the margin of the court's record of such license or certificate.
