Catatonia Associated with Hyperthyroidism: An Illustrative Case and Systematic Review of Published Cases.

Background: Catatonia is a frequently missed diagnosis on medical wards, delaying effective treatment or permitting accidental use of neuroleptics that can exacerbate the condition. Thyroid storm has rarely been associated with catatonia in case reports, with no prior reviews synthesizing this research.

Objective: We present a case of catatonia during thyroid storm following administration of low-dose haloperidol, followed by a review of previously published cases and discussion of their common factors and potential mechanisms.
