[Diagnosing epileptic seizures and epilepsy].

There are many episodic conditions which may be confused with epileptic seizures. The diagnosis of epileptic seizures is still dependent on a good history and witness report, as well as good knowledge of seizure semiology, and of the symptoms of a variety of differential diagnostic conditions. The principal differential diagnoses in adults and children are outlined in this review. The diagnostic problems do not exist only initially, so it is important to reconsider the diagnosis when deemed relevant. The possibility of home video recordings of recurring attacks may be helpful. Neuroimaging and interictal EEG cannot confirm or exclude epilepsy but can demonstrate relevant pathology and are of prognostic importance.
