Grand Mal (Tonic-Clonic) Seizures: Symptoms, Aftermath & Prognosis

Tonic-clonic seizure (grand mal) involves loss of consciousness + violent muscle contractions.

Phases

• Tonic: Sudden stiffening, fall, cry (forced air).
• Clonic: Rhythmic jerking (1–3 min).
• Postictal: Confusion, fatigue, headache, amnesia (minutes–hours).

Key Facts

• Typically no permanent brain damage from single seizure.
• Risks: injury from fall, aspiration, status epilepticus (>5 min = emergency).
• Not "loss of sanity"—epilepsy is a neurological condition.

Management

Antiseizure meds control most cases. First-time seizure → urgent evaluation (imaging, EEG, labs).
