Although pseudoseizures are a cause of drug toxicity (as escalating doses are used in an attempt to suppress seemingly intractable spells), in this brief report the exact converse is argued: namely, that a sub-group of pseudoseizures may arise as a reversible idiosyncratic toxic side-effect of GABAergic anticonvulsants. The term "organic pseudoseizures" is used to denote this group of medication related behavioural alterations.
