In Bowman v. Lemon (1926), 115 Ohio St. 326, 329-330, 4 Ohio Law Abs. 261, 4 Ohio Law Abs. 774, 154 N.E. 317, the Ohio Supreme Court stated that, when a plaintiff alleged that he was "of unsound mind" such that the limitations period should be tolled, a court should consider "whether there is any evidence tending to show any species of mental deficiency or derangement from which the plaintiff was suffering which would prevent him from properly consulting with counsel, preparing and presenting his case, and attending to his affairs, and preclude him from asserting his rights in a court of justice."
