Recherche étiologique lors d'un état de mal épileptique

Because of the wide range of etiologies which may provoke status epilepticus (SE), physical examination, laboratory tests and neuroimaging must be conducted according to a well-designed hierarchical system. While implementing intensive care management, clinicians must of course search for curable causes but also consider the possible interaction of multiple factors and hidden diseases favoring or triggering SE. Causes of SE in idiopathic or cryptogenic epilepsy and new-onset SE do not correlate but careful analysis of serum chemistry and neuroimaging abnormalities must nevertheless be conducted with the specific objective of establishing an etiological diagnosis.
