Seizures can be classified as acute symptomatic (ASS) or unprovoked (US). The first are those that occur during a systemic disorder or with a close temporal association with a documented brain injury. The aim of this study is to determine the frequency of ASS among first seizures within an elderly population, and to determine the etiology, clinical aspects and course with status epilepticus (SE).Also review the mortality in this group of patients, compared with that of US.All patients over 65 years with an initial seizure. They were classified as having presented ASS or US. Outcome was assessed as mortality within 30 days, making a comparison between the ASS and the US, and mortality as patients have developed or not an SE.We identified 181 patients with an initial seizure;30% of them were ASS. The most frequent cause was cerebrovascular disease (41%).50% of patients had an SE in its evolution. Mortality within 30 days of the event was 37% for ASS and 12% for US (p<0.001);in the group of patients with SE was higher than in those who did not suffered it, with 48% in the first and 25% in the second (p=0.15).The most common cause of ASS was cerebrovascular disease, with 41% of the total. The mortality among patients with ASS is higher than in patients with US. This is probably related to the severity of the underlying pathology causing the seizure.
