Seizures

Relevant information may include witness or video descriptions, emergency findings, medications and substance exposure, laboratory results such as glucose and electrolytes, signs of infection, neurological examination, brain imaging, and EEG findings when obtained. These records can help determine whether the event was an acute symptomatic seizure associated with an underlying medical or neurological condition, an unprovoked seizure requiring further neurological assessment, or another type of episode.

An expert may consider how the event began, the sequence of signs and symptoms, changes in consciousness or responsiveness, movements or sensations, duration, and the person’s condition afterward. Witness accounts, video when available, EEG findings, and neurological history may help classify an epileptic seizure as focal, generalized, unknown whether focal or generalized, or unclassified under current terminology. When available information is limited or conflicting, a more specific classification may not be possible.

Acute symptomatic seizures can occur in close temporal association with conditions such as severe metabolic disturbances, medication or substance effects, alcohol or drug withdrawal, central nervous system infection, stroke, traumatic brain injury, anoxic brain injury, or another acute neurological insult. The timing of the seizure, severity of the underlying condition, laboratory and imaging findings, medication history, and overall clinical course may help identify the most supported explanation.
