'Catatonia' due to disulfiram toxicity.

In an alcoholic patient, catatonia developed while he was receiving disulfiram (Antabuse). Resolution of the question whether his state was classically catatonic required a detailed review of the literature on the subject. The conclusion reached is that the original definition still holds for psychiatric illness, but application of the term to neurological and metabolic states has often been based on imprecise criteria and failure to consider akinetic mutism and extrapyramidal motor disturbances as factors. The action of disulfiram as an inhibitor of dopamine beta hydroxylase provides a possible mechanism for the cerebral toxic effect, but nonetheless the various interpretations remain largely speculative.
