Crisis convulsivas de orígen no encefálicas - revisión

Abstract

About 9% of the population will have at least one seizure lifelong. Seizures are the most common neurological manifestation in the departments of emergency, corresponding 1-5% of cases, excluding trauma. The objective of this paper is to discuss differential diagnoses seizure of non-brain origin. Review of the literature using PubMed, MEDLINE, Google Scholar, Clinical Trials, EBSCO, Scielo, and Radiology topics. Selected 60 papers according to inclusion and exclusion criteria due to 1927-2016. Seizures may result from abrupt discontinuation of use of antiepileptic drugs, structural lesions, metabolic disorders, poisoning, the abrupt cessation drugs such as benzodiazepines and barbiturates. There are also cases as, infections systemic or central nervous system such as meningitis, encephalitis and abscesses. Only a small portion has no defined cause. There are several etiologies to consider when we discuss about seizure. It is of utmost importance to keep in mind the differential diagnoses of seizures, because not every seizure is brain origined and do not need always be treated chronically with anti-epileptics.
