Query: Seizure pathways and seizure durations can vary independently within
  individual patients with focal epilepsy   A seizure's electrographic dynamics are characterised by its spatiotemporal
evolution, also termed dynamical "pathway" and the time it takes to complete
that pathway, which results in the seizure's duration. Both seizure pathways
and durations can vary within the same patient, producing seizures with
different dynamics, severity, and clinical implications. However, it is unclear
whether seizures following the same pathway will have the same duration or if
these features can vary independently. We compared within-subject variability
in these seizure features using 1) epilepsy monitoring unit intracranial EEG
(iEEG) recordings of 31 patients (mean 6.7 days, 16.5 seizures/subject), 2)
NeuroVista chronic iEEG recordings of 10 patients (mean 521.2 days, 252.6
seizures/subject), and 3) chronic iEEG recordings of 3 dogs with focal-onset
seizures (mean 324.4 days, 62.3 seizures/subject). While the strength of the
relationship between seizure pathways and durations was highly
subject-specific, in most subjects, changes in seizure pathways were only
weakly to moderately associated with differences in seizure durations. The
relationship between seizure pathways and durations was weakened by seizures
that 1) had a common pathway, but different durations ("elastic pathways"), or
2) had similar durations, but followed different pathways ("duplicate
durations"). Even in subjects with distinct populations of short and long
seizures, seizure durations were not a reliable indicator of different seizure
pathways. These findings suggest that seizure pathways and durations are
modulated by different processes. Uncovering such modulators may reveal novel
therapeutic targets for reducing seizure duration and severity.
