Case Report: Non-convulsive seizure following traumatic brain injury - a significant occurrence that needs to be considered due to potential long-term sequelae.

NCS may remain undiagnosed in TBI due to a paucity of overt clinical manifestations. Every patient with TBI and altered consciousness at presentation should be evaluated by continuous EEG monitoring immediately, if possible, in the emergency department to avoid long-term sequelae of NCS in such cases.
