Tonic Clonic Seizures
Tonic-clonic seizures, often referred to as grand mal seizures, are among the most dramatic and widely recognized types of seizures. These seizures involve a combination of muscle stiffening (tonic phase) and rhythmic muscle contractions (clonic phase). Let us explore an in-depth understanding of tonic-clonic seizures, covering their symptoms, causes, diagnosis, treatment options, and first aid measures.
What Are Tonic Clonic Seizures?
Tonic-clonic seizures are characterized by a sudden onset of muscle stiffness and convulsions. They are a form of generalized seizure, meaning they affect both hemispheres of the brain. These seizures can last from a few seconds to several minutes and are typically followed by a postictal state, where the individual may experience confusion, drowsiness, and fatigue.

Get A Second OpinionSymptoms of Tonic Clonic Seizures
The symptoms of tonic-clonic seizures can be divided into two phases: the tonic phase and the clonic phase.
Tonic Phase
- Sudden loss of consciousness
- Muscle stiffening, particularly in the back, legs, and arms
- Difficulty breathing or a temporary cessation of breathing
Clonic Phase
- Rhythmic jerking of the limbs and facial muscles
- Possible incontinence
- Biting of the tongue or inside of the cheek
Postictal State
- Drowsiness and confusion
- Headache
- Muscle soreness
- Amnesia regarding the seizure event
Causes of Tonic Clonic Seizures
A variety of factors can trigger tonic-clonic seizures. Understanding these triggers is crucial for effective management and prevention.
Common Triggers
- Sleep deprivation: Lack of adequate sleep can precipitate seizures.
- Stress: High levels of stress and anxiety are common triggers.
- Alcohol and substance abuse: Excessive alcohol consumption or withdrawal, as well as the use of recreational drugs, can induce seizures.
- Flashing lights: Photosensitivity can lead to seizures in some individuals.
- Medication non-compliance: Skipping or discontinuing anti-seizure medications can result in seizure activity.
Underlying Causes
- Genetic factors: A family history of epilepsy can increase the likelihood of tonic-clonic seizures.
- Brain injuries: Traumatic brain injuries or strokes can lead to seizure disorders.
- Infections: Infections like meningitis or encephalitis can cause seizures.
- Metabolic imbalances: Conditions such as hypoglycemia or hyponatremia can trigger seizures.
Diagnosis of Seizures
The diagnosis of seizures involves a comprehensive evaluation to identify the type of seizure and its underlying cause.
Medical History and Physical Examination
The first steps in diagnosing seizures are a detailed medical history and physical examination. This includes reviewing the patient's seizure history, family history, and any potential triggers or underlying conditions.
Electroencephalogram (EEG)
An EEG is a critical diagnostic tool that measures electrical activity in the brain. Abnormalities in brain wave patterns can help confirm the presence of seizures and provide information about their type and origin.
Imaging Studies
Imaging studies such as MRI or CT scans are often used to identify structural abnormalities in the brain that may be causing seizures. These scans can reveal tumours, scar tissue, or other lesions.
Blood Tests
Blood tests can help identify metabolic imbalances, infections, or other conditions that might be contributing to seizure activity.
Treatment for Tonic-Clonic Seizures
Effective treatment for tonic-clonic seizures typically involves a combination of medication, lifestyle changes, and, in some cases, surgery.
Medications
Anti-seizure medications are the cornerstone of treatment for tonic-clonic seizures. These drugs work by stabilizing electrical activity in the brain to prevent seizures. Commonly prescribed medications include:
- Phenytoin (Dilantin)
- Valproate (Depakote)
- Carbamazepine (Tegretol)
- Lamotrigine (Lamictal)
Lifestyle Changes
Lifestyle modifications can play a significant role in managing and reducing the frequency of seizures. These include:
- Ensuring adequate sleep: Maintaining a regular sleep schedule can help prevent seizures.
- Stress management: Techniques such as meditation, yoga, and deep breathing exercises can reduce stress levels.
- Avoiding triggers: Identifying and avoiding known seizure triggers is crucial.
Surgery
In cases where medication and lifestyle changes are not effective, surgical options may be considered. Procedures such as resective surgery, where the part of the brain causing seizures is removed, or vagus nerve stimulation, which involves implanting a device to send electrical impulses to the brain, can be effective.

Book an AppointmentSeizure First Aid
Knowing how to respond during a tonic-clonic seizure is essential for ensuring the safety of the individual experiencing the seizure.
What to Do
- Stay calm: Keep calm and reassure others around you.
- Protect from injury: Move any objects that could cause injury away from the person.
- Time the seizure: Note the start and end time of the seizure.
- Turn them on their side: This helps keep the airway clear and prevents choking.
- Place something soft under the head: A jacket or cushion can protect the head from injury.
- Stay with them: Remain with the person until they are fully awake and alert.
What Not to Do
- Do not restrain them: Holding the person down can cause injury.
- Do not put anything in their mouth: This can lead to choking or injury.
- Do not offer food or drink immediately after Wait until the person is fully alert.
Epilepsy Awareness and Education
Raising awareness about epilepsy and educating the public on seizure first aid can significantly improve the quality of life for individuals with epilepsy. Public education campaigns can dispel myths, reduce stigma, and promote understanding and support for those affected by this condition.
Frequently Asked Questions

Diagnosed through EEGs (electroencephalograms), brain scans, and medical history.
4. How are tonic-clonic seizures treated?
Treatment includes anti-seizure medications, lifestyle changes to avoid triggers, and sometimes surgery.
5. How can seizure first aid and triggers be managed?
Managing involves knowing seizure first aid, avoiding known triggers, and regularly taking prescribed medications.
