Cortical and thalamic hyper-perfusion in non-convulsive status epilepticus. Relationship between perfusion CT patterns and Salzburg EEG criteria

Status epilepticus (SE) is a common neurological emergency, with an incidence of 10-41 cases per 100 000 population [1,2] and a mortality rate of around 20% [2]. Nonconvulsive seizures, nonconvulsive status epilepticus (NCSE), and the postictal state, in particular, may masquerade as a stroke and often represent a diagnostic challenge [3] [4]. Failure in recognizing SE can have important negative consequences leading to incorrect treatment, diagnostic delay and potential treatment adverse effects [5].
