title: [Acute symptomatic epilepsies].
abstract: OBJECTIVE
  To review the differentiating characteristics of symptomatic acute epilepsies, epidemiology, aetiology and controversies over treatment, and describe our experience with symptomatic acute epilepsy in cerebrovascular disorders.
  
  
  CONCLUSIONS
  The so-called symptomatic acute epilepsies show clearly differentiated characteristics with regard to true epileptic disorders: 1. A clearly identified causal association; 2. Generally tend not to recur; 3. Usually long-term anti-epileptic treatment is not necessary. Therefore the most suitable term for them is symptomatic acute seizures. They make up a large proportion of all newly-diagnosed epilepsies around 40%. The highest incidence occurs during the first year of life (probably because of the high incidence of seizures due to encephalopathies, metabolic disorders and infections) and in elderly patients (especially in relations to cerebrovascular disorders). The commonest causes are: cerebrovascular disorders, head injury, infections of the central nervous system, alcohol and drugs. The risk of subsequent epilepsy is increased in a subgroup of these patients, especially in cases with associated cerebrovascular disorders, head injuries and central nervous system infection. Long-term preventive treatment is rarely indicated in these patients.
