Myoclonic status epilepticus following repeated oral ingestion of colloidal silver.

Author information

Department of Clinical Neurological Sciences, University of Western Ontario, London, Ontario, Canada.


The authors report a case of a 71-year-old man who developed myoclonic status epilepticus and coma after daily ingestion of colloidal silver for 4 months resulting in high levels of silver in plasma, erythrocytes, and CSF. Despite plasmapheresis, he remained in a persistent vegetative state until his death 5.5 months later. Silver products can cause irreversible neurologic toxicity associated with poor outcome.
