Regional Commissions
Seizure Types:
The 2006 Task force report provided a much more detailed list of seizure types than had been previously considered in common, daily use. The “Common” list presented in the 1981 Commission document is still largely valid. The list presented in the 2006 Task force report is very similar to the original list, however, in some areas, particularly for the focal seizures, it requires more detail than is typically collected or made available (see Table 3). Consequently, the common seizure list can be used for most purposes unless one can adequately ascertain the information needed to classify the seizures more precisely. An important exception to this involves epileptic spasms which should be specifically identified but were not explicitly included in the common list. In addition, there is continued controversy over the terms “simple” and “complex” partial (see foot note to table 3 and Engel, 2001). The relationship between ictal semiology and specific networks involved is at the heart of the matter. No specific changes have been formerly adopted. Those who use the seizure classification are urged to study this history and debate and proceed rationally. The purpose (e.g. research) to which the seizure classification is put to use will largely dictate the degree of detail that is necessary.
