Understanding Tonic-Clonic Seizures: A Human-Centered Guide
Tonic-clonic seizures, once commonly known as “grand mal seizures,” are one of the most recognized types of seizures. They involve sudden and intense physical symptoms that can be frightening to witness—but with the right understanding and support, people who live with these seizures can lead full and meaningful lives.
What Are Tonic-Clonic Seizures?
Tonic-clonic seizures are a type of generalized seizure, meaning they affect both sides of the brain. They typically occur in two stages:
-
Tonic Phase: This is the first part, where the person’s muscles stiffen. They may suddenly fall if standing, lose consciousness, and the body becomes rigid. Breathing might become difficult, and sometimes a cry or groan is heard as air is forced out of the lungs.
-
Clonic Phase: This is followed by rhythmic jerking of the limbs. The jerking movements can last from a few seconds to a couple of minutes. During this time, the person is unaware of what’s happening and cannot control their body.
What Causes These Seizures?
Tonic-clonic seizures can be caused by a range of conditions, including:
- Epilepsy: The most common cause. Epilepsy is a neurological disorder marked by recurrent seizures.
- Brain injury: Trauma from accidents or falls can lead to seizures.
- Stroke or tumors: These can disrupt normal brain activity.
- High fever (febrile seizures): More common in children.
- Genetic conditions or metabolic disorders.
Sometimes, the exact cause is unknown.
What Happens After the Seizure?
After a tonic-clonic seizure, the person may experience:
- Confusion and fatigue (postictal phase)
- Headache
- Muscle soreness
- Loss of memory about the event
It may take several minutes to hours to feel completely normal again. Each person’s recovery time varies.
How Can You Help Someone Having a Tonic-Clonic Seizure?
Watching someone have a seizure can be alarming, but here’s how you can help:
- Stay calm and keep others away.
- Ease the person to the ground and gently turn them on their side.
- Remove nearby objects to prevent injury.
- Place something soft under their head, like a folded jacket.
- Do NOT put anything in their mouth—they cannot swallow their tongue.
- Time the seizure: If it lasts more than 5 minutes, call emergency services.
- Stay with them until they are fully awake and safe.
Diagnosis and Treatment
If someone experiences a seizure, doctors usually recommend:
- EEG (electroencephalogram) to measure brain activity.
- Brain imaging (MRI or CT scan) to look for structural causes.
- Blood tests to check for infections or chemical imbalances.
Treatment may include:
- Anti-epileptic medications (AEDs) to prevent future seizures.
- Lifestyle adjustments (getting enough sleep, avoiding triggers).
- Surgery or neurostimulation for drug-resistant epilepsy.
- Ketogenic diet in some special cases, especially for children.
Living With Tonic-Clonic Seizures
A diagnosis of epilepsy or recurrent seizures doesn’t define a person’s life. Many people manage their seizures with medication and live full, active lives. Education, support, and understanding from friends, family, and society are vital.
Safety Tips:
- Avoid swimming alone or climbing heights.
- Use helmets during risky activities.
- Let close contacts know how to respond if a seizure happens.
Final Thoughts
Tonic-clonic seizures are dramatic, but with the right care and support, they are manageable. Understanding what happens, how to help, and the options for treatment empowers both those who experience seizures and the people around them. Compassion, awareness, and medical guidance can make a world of difference.
