mania transitoria.Hist. Insanity of brief duration, experienced while committing a criminal act.

• In a memorandum opinion, the Supreme Court used the term to mean emotional insanity. See Mutual Life Ins. Co. v. Terry, 82 U.S. 580, 583–84 (1872). But other courts have applied the literal meaning (temporary insanity). See, e.g., Rush v. Megee, 36 Ind. 69 (1871). Cf. emotional insanity, temporary insanity under INSANITY.
