Seizure epilepsy focal classification type
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.
  
Alphanumeric
Per degree of impairment
Tonic, clonic, atonic and epileptic spasm: When these seizure types occur in patients with combined focal and generalized epilepsy, it is often difficult to determine whether their onset is focal or generalized. Please use the Unknown Onset box in these cases. (e.g., Lennox Gastaut Syndrome).
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.

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 cortical and subcortical structures, but do not necessarily include the entire cortex, experienced by the participant/subject.
  
Alphanumeric
Answer all. If a seizure cannot be adequately classified, it should not be fit into a category to which it does not belong.
Specify type below
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.
