Seizure classification type
SeizClassTyp
The type of seizures present by classification.
Classification of Seizures
Generalized;Focal;Unclassified;
Generalized;Focal;Unclassified seizures are considered unidentifiable due to lack of data and do not fit in to the aforementioned categories for Generalized and Focal Seizures;
Alphanumeric
Choose all that apply. Each seizure type needs to be answered using the permissible values for the "Seizure type or subtype present likelihood type" data element. It is possible for a participant/subject to have more than one seizure type.

Seizure generalized classification type
SeizGenClassTyp
The type of generalized epileptic seizures, considered to originate at some point within, and rapidly engage, bilaterally distributed networks and may include such bilateral networks as ortical and subcortical structures, but do not necessarily include the entire cortex, experienced by the participant/subject.
Generalized Seizure Subtypes
Tonic clonic;Absence;Typical;Atypical;Myoclonic absence;Eyelid myoclonia;Myoclonic;Myoclonic atonic;Myoclonic tonic;Clonic;Tonic;Atonic;

Alphanumeric
Each seizure type needs to be answered using the permissible values for the "Seizure type or subtype present likelihood type" data element. It is possible for a participant/subject to have more than one seizure type. Although individual seizure onsets can appear localized, the location and lateralization are not consistent from one seizure to another. Generalized seizures can be asymmetric.

Seizure focal classification type
SeizFocClassTyp
The type of focal epileptic seizures, considered to originate within networks limited to one hemisphere, which may be discretely localized or more widely distributed, and may originate in subcortical structures, experience by the participant/subject.
Focal Seizure Subtypes
Without impairment of consciousness or responsiveness;With observable motor or autonomic components;Involving subjective sensory or psychic phenomena only;With impairment of consciousness or responsiveness;Evolving to a bilateral, convulsive seizure;
Without impairment of consciousness or responsiveness;Without impairment of consciousness or responsiveness-With observable motor or autonomic components (roughly corresponds to the concept of "simple partial seizure");Without impairment of consciousness or responsiveness-Involving subjective sensory or psychic phenomena only (corresponds to the concept of "aura");With impairment of consciousness or responsiveness (roughly corresponds to the concept of "complex partial seizure");Evolving to a bilateral, convulsive seizure (involving tonic, clonic, or tonic and clonic components replaces the term "secondarily generalized seizure");
Alphanumeric
Each seizure type needs to be answered using the permissible values for the "Seizure type or subtype present likelihood type" data element. It is possible for a participant/subject to have more than one seizure type. For each seizure type, ictal onset is consistent from one seizure to another with preferential propagation patterns, which can involve the contralateral hemisphere. In some cases, however, there is more than one epileptogenic network, and more than one seizure type, but each individual seizure type has a consistent site of onset. Focal seizures do not fall into any recognized set of natural classes based on any current understanding of the mechanisms involved.
