Person Currently Having a Seizure

The human cerebral cortex functions through synchronized electrochemical signaling regulated by inhibitory and excitatory neurotransmitters. Occasionally, a sudden hypersynchronous neuronal discharge sweeps across the brain, temporarily overwhelming normal neurochemical regulation.

During a generalized tonic-clonic seizure (formerly known as grand mal), this electrical storm causes simultaneous tonic muscular contraction (causing the person to collapse and stiffen) followed by clonic rhythmic contractions across the entire skeletal musculature.

The Phases of a Tonic-Clonic Seizure

1. Tonic Phase (10–30 seconds): All skeletal muscles contract simultaneously. The vocal cords may spasm, forcing air past the glottis in an involuntary vocalization ("ictal cry"). The chest muscles stiffen, causing temporary shallow breathing and cyanosis (bluish tint around the lips).
2. Clonic Phase (30–90 seconds): The brain attempts to restore inhibitory control, resulting in alternating bursts of contraction and relaxation that manifest as rhythmic jerking of the extremities. Saliva may foam at the mouth, and involuntary tongue biting may produce pink-tinged sputum.
3. Post-Ictal Phase (Several minutes to hours): As normal cerebral electrophysiology resets, the person enters a state of deep muscular flaccidity, heavy breathing, and profound drowsiness, confusion, or headache.

Debunking Dangerous Folk Beliefs

For decades, well-meaning bystanders have inflicted severe harm on seizing individuals due to dangerous misconceptions:

• "Swallowing the Tongue": It is anatomically impossible to swallow one's own tongue. The lingual frenulum firmly anchors the base of the tongue to the floor of the oral cavity. Shoving fingers, wallets, or spoons into a clenched jaw shatters teeth and forces jagged fragments down the larynx.
• Forcible Restraint: Attempting to pin down violently jerking limbs causes tearing of the biceps, pectoral muscles, and shoulder dislocations. First aid consists purely of environmental protection: let the electrical event run its course while guarding the skull against impact trauma.

The 5-Minute Emergency Threshold (Status Epilepticus)

The vast majority of unprovoked seizures terminate spontaneously within 60 to 120 seconds. However, if active generalized convulsions continue beyond 5 minutes, the brain's internal inhibitory mechanisms have failed, entering a life-threatening medical emergency known as Status Epilepticus. Prolonged uninterrupted seizure activity leads to systemic hyperthermia, metabolic acidosis, rhabdomyolysis, and permanent excitotoxic neuronal destruction, requiring immediate intravenous antiepileptic therapy by emergency physicians.
