Which EEG patterns in coma are nonconvulsive status epilepticus?
Nonconvulsive status epilepticus (NCSE) is common in patients with coma with a prevalence between 5% and 48%. Patients in deep coma may exhibit epileptiform EEG patterns, such as generalized periodic spikes, and there is an ongoing debate about the relationship of these patterns and NCSE.

متن کاملEmergency ("stat") EEG in the era of nonconvulsive status epilepticus.
The most widely accepted indication for a stat EEG (stEEG) is the suspicion of nonconvulsive status epilepticus (NCSE). NCSE has been reported with surprising frequency in a wide variety of acute structural and metabolic brain injuries and significantly increases the risk of permanent brain damage and death. This risk rises and the effectiveness of treatment decreases with delays in diagnosis a...
متن کاملNonconvulsive status epilepticus and coma.

In many advanced coma stages, the EEG exhibits continuous or periodic EEG abnormalities, but their causal role in coma remains unclear in many cases. To date there is no consensus on whether to treat NCSE in a comatose patient in order to improve the outcome or to retract from...
