Prolonged toxicant-induced seizures may respond differently from early seizures, but the proposed mechanism is supported more strongly by experiments than by controlled human evidence.
The narrative review describes an early cholinergic trigger followed by glutamatergic activity, inflammation and weakening GABA-mediated inhibition during sustained seizures. This framework predicts declining responsiveness to benzodiazepine monotherapy as seizures continue. The authors propose a Stage 1 Plus approach for delayed presentations and nonconvulsive status with coma.
This is an interpretive review, not a trial validating the proposed treatment sequence. Human reports differ in recognition delay, resuscitation and EEG confirmation. Experimental receptor changes do not establish exactly when a particular patient became treatment-resistant.
For a poisoning reconstruction, document exposure, onset, first effective drug delivery and EEG findings separately. Failure after delayed treatment does not necessarily show an inadequate dose or an incorrect diagnosis. Conversely, a mechanistic explanation cannot prove that an earlier intervention would have prevented a specific injury. The timeline and evidence of ongoing seizures remain central.
