The One-Line Truth
The whole disease in one chain
Everything on this page exists to explain this line.
A seizure that lasts longer than 5 minutes, or seizures that come back without the person waking up in between, is status epilepticus (a seizure that will not stop) — a brain emergency that needs medicine right away.
Brain's Electrical Grid in Blackout Mode
Imagine a city's power grid where power plants (neurons) are supposed to send electricity (action potentials) only when the control center says go. Normally, the dispatcher (GABA) sends "stop" signals that flip switches off, and the demand center (glutamate) sends "go" signals that flip switches on — they balance perfectly so lights turn on and off in rhythm. But in status epilepticus (a seizure that will not stop), the dispatcher stops answering calls (GABA receptors vanish from the surface) or someone jams the gas pedal (glutamate floods the system), so every switch flips on at once and stays on. The power lines overheat (calcium toxicity kills neurons), the backup generators burn out trying to keep up (ATP depletion), and the cooling system fails (hyperthermia). By the time someone arrives with the master switch, the control room itself has been damaged by the fire (receptor downregulation makes benzodiazepines less effective), and the longer you wait, the more permanent the damage to the building's wiring (excitotoxicity after 30–60 minutes).
