Engel_2001_1.0_Diagnostic_Scheme

Engel 2006 The objective will be to make any new classification adaptable to be used for specific purposes, including exchange of clinical information among physicians, teaching, clinical research activities such as epidemiological studies and drug trials, basic research, and genetic investigations. Table 1: Proposed diagnostic scheme for people with epileptic seizures and with epilepsy Epileptic seizures and epilepsy syndromes are to be described and categorized according to a system that utilizes standardized terminology and that is sufficiently flexible to take into account the following practical and dynamic aspects of epilepsy diagnosis: (1) Some patients cannot be given a recognized syndromic diagnosis. (2) Seizure types and syndromes change as new information is obtained. (3) Complete and detailed descriptions of ictal phenomenology are not always necessary. (4) Multiple classification schemes can, and should, be designed for specific purposes (e.g. communication and teaching; therapeutic trials; epidemiological investigations; selection of surgical candidates; basic research; genetic characterizations). This diagnostic scheme is divided into five parts, or Axes, organized to facilitate a logical clinical approach to the development of hypotheses necessary to determine the diagnostic studies and therapeutic strategies to be undertaken in individual patients: Axis 1: Ictal phenomenology—from the Glossary of Descriptive Ictal Terminology, can be used to describe ictal events with any degree of detail needed. Asix 2: Seizure type: from the List of Epileptic Seizures. Localization within the brain and precipitating stimuli for reflex seizures should be specified when appropriate. Axis 3: Syndrome: from the List of Epilepsy Syndromes, with the understanding that a syndromic diagnosis may not always be possible. Axis 4: Etiology: from a Classification of Diseases Frequently Associated with Epileptic Seizures or Epilepsy Syndromes when possible, genetic defects, or specific pathological substrates for symptomatic focal epilepsies. Axis 5: Impairment: this optional, but often useful, additional diagnostic parameter can be derived from an impairment classification adapted from the WHO ICIDH-2. The diagnostic scheme described here will be made up of flexible and dynamic modules within which the Task Force will make periodic changes and updates as needed, with the approval of the Executive Committee. The Task Force is proposing that this diagnostic scheme include the development of flexible, rather than rigid, classifications, eliminating the need for the General Assembly, which meets only once every 2 years, to agree on every revision. Acceptance of this diagnostic scheme, therefore, does not exclude the creation of various classification systems for seizures and syndromes, or the continued use of some aspects of the current classification. The Task Force will be concerned with the construction of classification systems during the next Executive term, but it is anticipated that seizures and syndromes will not be organized into fixed dichotomous classifications, but rather categorized in various ways for various purposes.
