There have been numerous reports documenting the occurrence of self-limiting seizures after carbon monoxide poisoning in the pediatric population. However, the literature has been less informative concerning the adult population. This report documents a 70-year-old female who was found to be in nonconvulsive status epilepticus after acute carbon monoxide poisoning with a carboxyhemoglobin level of 35%. To our knowledge, this is the first report of acute carbon monoxide poisoning inducing nonconvulsive status epilepticus in an adult. This report adds to the growing body of knowledge concerning acute carbon monoxide poisoning by further exploring the very complex symptomatology that presents in the adult population.
