###Human: Following first seizure attack, one should opt immediate treatment or wait for the second one? ###Assistant: Hi. I have gone through the query. A person can develop two seizures without regaining consciousness in between or one episode of status epilepticus lasting for more than five minutes. Seizures occurring for 15 minutes requires treatment, and it needs evaluation like EEG (electroencephalography), MRI brain (magnetic resonance imaging), serum calcium and electrolytes, and blood glucose.
