Understanding Generalized Seizures / Tonic-clonic Seizures

Generalized seizures — also called tonic-clonic or grand mal seizures — are episodes where the whole brain is affected, causing a person to lose consciousness, fall, and shake uncontrollably. They can be frightening to witness, but many people recover fully with the right care and treatment. If you or someone you know has had a seizure, it is important to see a doctor so the cause can be found and managed.

Common Symptoms / Concerns for Generalized Seizures / Tonic-clonic Seizures

Sudden loss of consciousness
Stiffening of the whole body
Uncontrollable jerking or shaking of the arms and legs
Falling to the ground without warning
Biting the tongue or inside of the cheek
Loss of bladder or bowel control
Confusion or drowsiness after the episode
Brief cry or shout at the start of the seizure
Temporary difficulty speaking or remembering what happened
Feeling very tired and weak after the seizure

When to Seek Professional Care

Book an evaluation with a healthcare provider immediately if you experience or present with:

  • Seizure lasting more than 5 minutes without stopping
  • A second seizure happens shortly after the first one
  • The person does not wake up or regain consciousness after the seizure
  • This is the person's first-ever seizure
  • The person is injured during the seizure (e.g. head injury or broken bone)
  • The person is pregnant or has diabetes
  • Seizures are happening more often than usual
  • The person has difficulty breathing after the seizure ends

What to Expect During Your Medical Consultation

When you visit the doctor for a seizure, they will ask you questions about what happened before, during, and after the episode — it helps to bring someone who witnessed it. The doctor will examine you and may order tests such as a blood test or a brain scan (EEG or CT scan) to understand the cause. Do not be afraid — the doctor is there to help you find the right treatment so you can live well.

Frequently Asked Questions

What causes generalized (grand mal) seizures?

Seizures can be caused by many things, including epilepsy, high fever, low blood sugar, head injuries, infections like malaria or meningitis, or a lack of sleep. Sometimes the cause is not immediately clear and the doctor will run tests to find out. Knowing the cause helps the doctor choose the best treatment for you.

Can I treat seizures at home with herbs or traditional medicine?

While some people try home or herbal remedies, seizures are a medical condition that needs proper diagnosis and treatment from a trained doctor. Using herbs alone can be dangerous and may delay the care you need. It is best to see a doctor first — they can work with you on a safe treatment plan.

What treatments are available for generalized seizures?

The most common treatment is anti-seizure medication, which helps control or stop seizures in most people. Your doctor will prescribe the right medicine and dose for you, and it is very important to take it every day as directed. With the right treatment, many people with epilepsy live normal, healthy lives.

Can generalized seizures be prevented?

Taking your prescribed medication regularly is the most important way to prevent seizures. You should also avoid known triggers such as missed sleep, alcohol, flashing lights, and skipping meals. Regular follow-up visits with your doctor will help keep your condition under control.

Is epilepsy or having seizures contagious?

No — seizures and epilepsy are not contagious and cannot be passed from one person to another. They are caused by changes in the brain's electrical activity, not by germs or spirits. It is safe to be around, help, and support someone who has seizures.
