Tonic-clonic seizures, also known as grand mal seizures, are the most dramatic and recognizable type of epileptic seizures. They involve the entire body and can be frightening to witness. These seizures have an impact on both the person experiencing them and those around them, often requiring immediate action and long-term management strategies.
Understanding tonic-clonic seizures is crucial to provide proper care and support. This article aims to explore what these seizures are, how to recognize their signs and symptoms, and the appropriate first aid measures to take. Additionally, it will delve into various treatment options and management techniques available to help individuals living with this condition. By gaining knowledge about tonic-clonic seizures, people can better prepare themselves to handle these medical emergencies and support those affected by them.
What is a Tonic-Clonic Seizure?
A tonic-clonic seizure, formerly known as grand mal seizure, is a type of generalized seizure that involves the entire body and is associated with impaired awareness or complete loss of consciousness. It is the most dramatic and recognizable type of epileptic seizure, often requiring immediate action and long-term management strategies.
Tonic-clonic seizures comprise two distinct stages: the tonic phase and the clonic phase. During the tonic phase, the person loses consciousness and experiences a generalized stiffening of the muscles, which can force air out of the lungs, resulting in a cry or moan. The person may fall to the floor and bite their tongue or cheek, causing saliva to appear bloody.
The clonic phase follows, characterized by rapid and rhythmic jerking movements of the arms and legs, bending and relaxing at the elbows, hips, and knees. These jerking movements typically last for one to three minutes before slowing down and eventually stopping. During this phase, the person’s face may appear dusky or bluish due to difficulty breathing, and they may lose control of their bladder or bowel as the body relaxes.

After the seizure, the person remains unconscious for several minutes as the brain recovers. They may appear to be sleeping or snoring and gradually regain awareness, feeling confused, exhausted, physically sore, sad, or embarrassed for a few hours. Memory loss surrounding the seizure event is common.
Tonic-clonic seizures generally last between one to three minutes. If a seizure lasts longer than five minutes, it is considered a medical emergency, and immediate help should be sought. Prolonged seizures, known as status epilepticus, require emergency treatment in a hospital setting to prevent potentially life-threatening complications.
Recognizing the Signs and Symptoms
Tonic-clonic seizures often have a distinct pattern of signs and symptoms that can be recognized by observers. These seizures may start with an aura, followed by the tonic and clonic phases, and end with a postictal state.
Some individuals may experience an aura before the onset of a tonic-clonic seizure. An aura is a subjective sensation that can serve as a warning sign of an impending seizure. These sensations may include changes in mood, perception, or physical sensations such as nausea or dizziness.
During the tonic phase, the person loses consciousness and their muscles suddenly stiffen, causing them to fall to the ground. They may let out a cry or moan due to the forceful contraction of the chest muscles. The person’s face may appear pale or bluish due to impaired breathing.
The clonic phase follows, characterized by rhythmic jerking movements of the face, arms, and legs. These convulsions typically last for one to three minutes. During this phase, the person may bite their tongue or cheek, resulting in bloody saliva. They may also lose control of their bladder or bowel.
After the seizure, the person enters the postictal state. They may remain unconscious for several minutes as the brain recovers. Gradually, they regain awareness but may feel confused, exhausted, or experience headaches. Memory loss surrounding the seizure event is common. In some cases, individuals may exhibit abnormal or combative behavior during this period.
Recognizing these signs and symptoms is crucial for providing appropriate first aid and seeking medical help when necessary. If a tonic-clonic seizure lasts longer than five minutes or if the person does not regain consciousness after the seizure, it is considered a medical emergency, and immediate assistance should be sought.
First Aid for Tonic-Clonic Seizures
Witnessing a tonic-clonic seizure can be a frightening experience, but it is essential to remain calm and take appropriate actions to ensure the person’s safety. Although these seizures may appear painful, the individual is not conscious during the episode and is unaware of what is happening. Here are some important steps to follow when providing first aid for tonic-clonic seizures:
Do’s during a seizure
- Look around and ensure the person is in a safe place. If not, gently move them away from any potential hazards.
- Cushion their head with something soft to prevent injury.
- Loosen any tight clothing, especially around the neck, to facilitate breathing.
- Time the seizure, as this information can be helpful for medical professionals.
- Once the seizure has stopped, gently place the person in the recovery position and check their breathing.
- Stay with them until they have fully recovered, offering reassurance and support.

Don’ts during a seizure
- Do not attempt to restrain or hold the person down during the seizure.
- Do not put anything in their mouth, as this can cause injury or obstruct their airway.
- Do not give them anything to eat or drink until they have fully recovered.
- Do not try to move the person unless they are in immediate danger.
When to call emergency services
In most cases, a tonic-clonic seizure does not require emergency medical attention. However, it is crucial to call 911 if any of the following situations occur:
- The seizure lasts longer than five minutes or is followed immediately by another seizure without recovery in between.
- The person has difficulty breathing after the seizure has stopped.
- They have sustained a serious injury during the seizure.
- It is the person’s first known seizure.
- You are unsure about the duration of their typical seizures.
Remember, the primary goal of first aid for tonic-clonic seizures is to ensure the person’s safety and provide a supportive environment for recovery. By following these guidelines, you can help minimize the risk of injury and provide essential care during and after the seizure.
Treatment Options and Management
The treatment of tonic-clonic seizures involves a combination of medication, lifestyle modifications, and in some cases, surgical interventions. The primary goal is to control and prevent seizures while minimizing side effects and improving the person’s quality of life.
Anti-epileptic medications are the first line of treatment for tonic-clonic seizures. These drugs work by reducing the abnormal electrical activity in the brain that causes seizures. The choice of medication depends on factors such as the type of seizure, age, overall health, and potential side effects. It may take some trial and error to find the most effective medication and dosage for each individual. Regular follow-up with a neurologist is essential to monitor the effectiveness of the treatment and make adjustments as needed.

In cases where medication alone does not provide adequate seizure control, surgical interventions may be considered. Epilepsy surgery involves removing or altering the area of the brain where seizures originate. The most common type of epilepsy surgery is temporal lobe resection, which involves removing a portion of the temporal lobe. Other surgical options include laser interstitial thermal therapy (LITT), deep brain stimulation (DBS), and corpus callosotomy. The decision to undergo surgery is based on a thorough evaluation of the individual’s seizure history, brain imaging, and other diagnostic tests.
Lifestyle modifications can also play a significant role in managing tonic-clonic seizures. Getting adequate sleep, managing stress, avoiding alcohol and drugs, and maintaining a healthy diet are all important factors in reducing seizure frequency. Some people may also benefit from keeping a seizure diary to identify potential triggers and make necessary lifestyle adjustments. Additionally, engaging in regular exercise and maintaining a consistent sleep schedule can help improve overall brain health and reduce the risk of seizures.
Conclusion
To wrap up, tonic-clonic seizures have a significant impact on individuals and their loved ones, requiring immediate action and long-term management. Understanding the signs, symptoms, and proper first aid measures is crucial to ensure the safety of those experiencing these seizures. The various treatment options, including medications, surgical interventions, and lifestyle modifications, offer hope to improve seizure control and quality of life.
Dealing with tonic-clonic seizures is an ongoing process that involves medical professionals, patients, and their support networks. By staying informed about the latest advancements in epilepsy care and maintaining open communication with healthcare providers, individuals can work towards better seizure management. This holistic approach, combining medical treatments with lifestyle adjustments, paves the way for those affected by tonic-clonic seizures to lead fulfilling lives despite the challenges posed by this condition.
