Ohio Rev. Code § 2305.16
Unless otherwise provided in sections 1302.98, 1304.35, and 2305.04 to 2305.14 of the Revised Code, if a person entitled to bring any action mentioned in those sections, unless for penalty or forfeiture, is, at the time the cause of action accrues, within the age of minority or of unsound mind, the person may bring it within the respective times limited by those sections, after the disability is removed. When the interests of two or more parties are joint and inseparable, the disability of one shall inure to the benefit of all.
After the cause of action accrues, if the person entitled to bring the action becomes of unsound mind and is adjudicated as such by a court of competent jurisdiction or is confined in an institution or hospital under a diagnosed condition or disease which renders the person of unsound mind, the time during which the person is of unsound mind and so adjudicated or so confined shall not be computed as any part of the period within which the action must be brought.
