Seizures are neurological events that are alarming and potentially life-threatening if not properly managed. Understanding the nature of seizures, their different types, causes, and appropriate first aid measures is crucial in ensuring the safety and well-being of individuals experiencing them. This article will explore the various aspects of seizures and how to respond effectively to someone having a seizure.
What is a seizure?
A seizure is a sudden, uncontrolled surge of electrical activity in the brain, disrupting its normal functioning. This abnormal electrical discharge causes a wide range of physical and behavioral manifestations, which vary depending on the specific area of the brain affected and the intensity of the seizure.
In a seizure, symptoms like convulsions, muscle rigidity, involuntary movements, consciousness changes, and sensation alterations are common. These manifestations are alarming to witness and often appear as involuntary jerking or shaking movements accompanied by changes in awareness, behavior, or sensations.
Seizures last a few seconds to several minutes and may be followed by confusion, fatigue, or headache. Recognizing these signs and responding appropriately is essential to ensure the person's safety during a seizure.
What are the 2 types of seizures?
The two main types of seizures are focal seizures (also known as partial seizures) and generalized seizures.
Focal seizures or partial seizures originate in a specific area of the brain and affect only part of the brain. The manifestations of focal seizures vary widely depending on the part of the brain involved:
- Simple Focal Seizures: These seizures affect a specific part of the brain and often result in altered sensations, emotions, or movements. The person may remain conscious during these seizures.
- Complex Focal Seizures: These seizures originate in a specific brain area but lead to altered consciousness or awareness. People experiencing complex focal seizures may display unusual behaviors, automatisms (repetitive, involuntary movements), or confusion.
In generalized seizures, the entire brain experiences abnormal electrical disruptions. Unlike focal seizures, generalized seizures affect both sides of the brain from the beginning of the episode. There are different types of generalized seizures, including:
- Tonic-Clonic Seizures: Also known as grand mal seizures, these are the most widely recognized type of generalized seizure. They involve loss of consciousness, stiffening of the body (tonic phase), and rhythmic jerking movements (clonic phase).
- Absence Seizures: These are brief, non-convulsive seizures that primarily affect children. During an absence seizure, the person may appear to be staring blankly into space, with a sudden interruption in their activities. They usually last only a few seconds.
- Atonic Seizures: These seizures lead to a sudden loss of muscle tone, causing a person to collapse or drop their head. They are sometimes referred to as "drop attacks."
- Myoclonic Seizures: These seizures involve sudden, brief muscle jerks or twitches. They can affect a single muscle group or the entire body.
- Clonic Seizures: These seizures are characterized by repetitive, rhythmic jerking movements, similar to the clonic phase of a tonic-clonic seizure.
- Tonic Seizures: Tonic seizures cause sudden muscle stiffening, often leading to falls or postural changes.
- Generalized Tonic-Clonic Seizures: This term is used when a seizure starts as a generalized seizure involving both sides of the brain without any preceding focal seizure activity. It includes the typical features of tonic and clonic phases.
- Infantile Spasms (West Syndrome): These are specific seizures in infants and young children. They involve sudden, symmetric, brief muscle contractions, often with a characteristic head nodding.
What causes seizures?
Seizures are caused by various factors, and identifying the underlying cause is crucial for appropriate treatment and management. Some potential causes of seizures include:
- Epilepsy: Epilepsy is a chronic neurological disorder characterized by recurrent seizures. Genetic factors cause it or occur due to unknown causes.
- Brain Injuries: Traumatic brain injuries resulting from accidents or falls that lead to seizures. The brain's structure and function may be altered, triggering abnormal electrical activity.
- Infections: Infections such as meningitis, encephalitis (brain inflammation), or brain abscesses cause seizures by affecting the brain tissue and its normal functioning.
- Metabolic Disorders: Certain metabolic disorders, including hypoglycemia (low blood sugar), electrolyte imbalances, or kidney failure, disrupt the brain's electrical activity and trigger seizures.
- Brain Tumors: Benign or malignant tumors in the brain cause seizures by putting pressure on brain tissue or interfering with normal electrical signals.
- Stroke: Strokes, which occur due to disrupted blood flow to the brain, damage brain tissue and lead to seizures.
- Genetic Factors: Some genetic conditions or mutations predispose individuals to seizures, even without any underlying cause.
- Withdrawal from Substances: Seizures occur during withdrawal from drugs, alcohol, or certain medications.
- Neonatal Causes: Seizures occur in newborns due to complications during birth, lack of oxygen, or infections passed from the mother.
- Idiopathic Seizures: In some cases, seizures may occur without an identifiable cause. These are referred to as idiopathic seizures and the underlying reason remains unknown.
How to Identify Signs of a Seizure
Seizures manifest in various ways, and the signs and symptoms differ based on the type of seizure and the area of the brain affected. Here are some common signs and symptoms associated with seizures:
- Convulsions: Convulsions are involuntary, rhythmic body movements, often involving jerking of the arms and legs. This is a characteristic symptom of generalized tonic-clonic seizures, during which the person loses consciousness and experiences both tonic and clonic phases.
- Loss of Consciousness: Many seizures result in a loss of consciousness. The person may suddenly stop what they are doing, stare blankly, and become unresponsive. This occurs in various types of seizures, including complex focal seizures and generalized seizures.
- Altered Awareness: Some seizures, particularly simple focal seizures change a person's awareness without causing a loss of consciousness. Individuals may experience unusual sensations, emotions, or perceptions during these seizures. They might feel detached from reality, experience déjà vu, or have strange tastes or smells.
- Repetitive Movements (Automatisms): Automatisms are repetitive, purposeless movements that occur during certain types of seizures. These movements might include lip-smacking, hand rubbing, or picking at clothes. Automatisms are commonly seen in complex focal seizures.
- Muscle Stiffness or Rigidity: Muscle stiffness, also known as tonic activity, occurs in various types of seizures. During tonic seizures, the muscles suddenly become stiff, leading to rigidity. This causes the person to fall if they are standing or sitting.

What are the 3 stages of seizure?
Seizure is categorized into different stages, each with distinct characteristics. Understanding these 3 stages helps recognize and respond to seizures effectively. Here are the typical stages of a seizure:
1. Aura (Prodrome): Some individuals experience warning signs or auras before a seizure occurs. These include changes in mood, sensation, or perception. Auras vary widely among individuals and are a precursor to an impending seizure.
2. Ictal Phase: The ictal phase is the actual seizure period when abnormal electrical activity occurs in the brain. This phase varies in duration and intensity. During this stage, the person may exhibit various symptoms, such as loss of consciousness, muscle jerking, altered awareness, or repetitive movements.
3. Postictal Phase: Following the ictal phase, there is a recovery period known as the postictal phase. During this stage, the person may appear confused, disoriented, or fatigued. They might experience headaches, muscle aches, or memory difficulties. The duration of the postictal phase varies, ranging from minutes to hours.
First Aid for Seizures
Providing first aid for seizures involves specific steps aimed at ensuring the person's safety and well-being during the episode. Here's a guide on how to respond effectively to someone experiencing a seizure:
Safety Measures for the Person Having a Seizure
Ensuring the safety of someone experiencing a seizure is critical. To ensure safety, clear the immediate area of any potential hazards, such as sharp objects or furniture, to prevent injury during the seizure.
Place a soft cushion or folded clothes under the person's head to protect them from head injuries. It's essential to loosen any tight clothing, especially around the neck, to facilitate proper breathing.
Gently turn the person onto their side to maintain an open airway and prevent choking on saliva or vomit. Avoid restraining their movements unless they are in immediate danger, as this could cause injury. Keep track of the seizure's duration, especially if it lasts longer than 5 minutes, as this warrants close medical attention.
Calling for Professional Help
If the seizure persists for more than 5 minutes or the person experiences another seizure immediately after the first, it is crucial to call emergency services. Additionally, seeking medical assistance is essential if it's the person's first seizure or if they have difficulty breathing or sustain an injury during the seizure. For pregnant individuals with underlying health conditions such as diabetes, it's vital to seek medical help promptly to ensure their well-being and safety.
Combining CPR with Seizure First Aid
When the person stops breathing or their heartbeat becomes irregular, combining CPR with seizure first aid is necessary. Start by checking for breathing and a pulse; if absent, begin CPR immediately. Initiate chest compressions at a rate of 100-120 compressions per minute, allowing the chest to fully recoil between compressions. Continue CPR until professional medical help arrives or until the person resumes breathing and has a regular heartbeat. Combining CPR with seizure first aid is be life-saving, especially when swift and efficient actions are taken.
When to Start CPR During a Seizure
Begin CPR if the person stops breathing or you cannot find a pulse, indicating an irregular heartbeat. In these situations, it's essential to start chest compressions immediately, maintaining the correct rate and depth to ensure adequate circulation. Initiating CPR promptly during a seizure significantly improves the person's chances of survival and reduces the risk of complications. Always prioritize the person's safety and well-being, following the appropriate CPR and seizure first aid protocols.
Age-Specific Considerations for Providing Seizure First Aid
There are age-specific considerations for providing seizure first aid. For children, it's crucial to be gentle when guiding them to the ground during a seizure to prevent injuries. Cushioning their head and removing nearby sharp objects is especially important.
In older adults with conditions like osteoporosis, extra care should be taken to prevent fractures during a fall. Additionally, for elderly individuals, post-seizure confusion might be more pronounced, requiring patience and reassurance.
Is it Safe to Put Something in the Mouth of a Person During a Seizure?
No, it is not safe to put anything in a person's mouth during a seizure. This is a common misconception. Placing an object in the mouth causes teeth, jaw, or airway injury. It's essential to ensure the person's safety by clearing the area and turning them on their side to prevent choking. The myth of swallowing the tongue during a seizure is not true; there's no need to put anything in the person's mouth.
Can Seizures be Fatal?
While most seizures are not fatal, they can lead to complications, especially if proper first aid is not administered. For instance, injuries sustained during a seizure, such as falls or accidents, can be serious. Additionally, if a seizure leads to losing consciousness while swimming or driving, it is life-threatening.
In very rare cases, seizures cause sudden unexpected death in epilepsy (SUDEP), which is unexplained death in someone with epilepsy, especially during or after a seizure. However, it's important to note that SUDEP is extremely rare and occurs in a small percentage of individuals with epilepsy. Proper management, medication adherence, and seizure safety precautions significantly reduce the risks associated with seizures.
Medications for seizure control
Antiepileptic medications, also called anticonvulsants, are prescribed to individuals with epilepsy or seizure disorders to reduce the frequency and severity of seizures. The choice of medication depends on the specific type of seizure and the individual's overall health.
Common medications include Carbamazepine (Tegretol), Valproic Acid (Depakote), Phenytoin (Dilantin), Lamotrigine (Lamictal), Levetiracetam (Keppra), and Topiramate (Topamax). Each medication targets specific seizure types and requires careful monitoring for effectiveness and potential side effects. Proper management and adherence to medication regimens are crucial for controlling seizures and improving the quality of life for individuals with epilepsy.
How to assist someone taking seizure medication?
Assisting someone with seizure medication involves ensuring they take their prescribed drugs regularly and on time. Encourage a consistent routine, use pill organizers, and help with medication refills. Monitor for any side effects and support them in communicating concerns to their healthcare provider. Emotional support and understanding are essential in helping them maintain their medication regimen effectively.
Which type of seizure requires the most immediate response?
Status epilepticus is the most critical type of seizure that demands an immediate response. Status epilepticus is a medical emergency where a seizure lasts for more than 5 minutes or when a person experiences consecutive seizures without regaining consciousness in between. This condition requires urgent medical intervention, including administering emergency medications and seeking immediate professional medical help. Status epilepticus is life-threatening, emphasizing the need for a swift and appropriate response to ensure the person's safety and prevent complications.
How does epilepsy relate to seizures?
Epilepsy and seizures are closely related, but they are not the same. Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures. In other words, epilepsy is a condition in which a person experiences a tendency to have seizures due to abnormal electrical activity in the brain. Seizures, on the other hand, are the visible or perceptible signs of this abnormal electrical activity.
Epilepsy is diagnosed when a person experiences two or more unprovoked seizures. Unprovoked means that a specific trigger, such as fever, head injury, or drug withdrawal, does not cause the seizures. It is important to note that not all seizures are due to epilepsy. Specific factors provoke some seizures and may not recur once the underlying cause is treated or removed.
Are there any common triggers for seizures?
Yes, there are several common triggers that provoke seizures in individuals with epilepsy. It's important to note that triggers vary from person to person, and what affects one individual may not affect another. Some common triggers for seizures include:
- Missed Medications: Skipping or missing doses of anti-epileptic medications disrupt the balance of chemicals in the brain, potentially triggering seizures.
- Lack of Sleep: Sleep deprivation or irregular sleep patterns lower the seizure threshold, making a person more susceptible to seizures.
- Stress and Anxiety: Emotional stress, anxiety, and other strong emotions trigger seizures in some individuals.
- Flickering Lights: Intense or flashing lights, such as those from strobe lights or video games, trigger seizures in susceptible individuals. This condition is known as photosensitive epilepsy.
- Alcohol and Drug Use: Excessive alcohol consumption and certain recreational drugs lower the seizure threshold and trigger seizures.
- Hormonal Changes: Hormonal fluctuations, especially in women during menstruation, pregnancy, or menopause, trigger seizures.
- Illness and Fever: High fever, especially in children, sometimes triggers febrile seizures. Other illnesses, particularly those causing high fever and dehydration increase the risk of seizures.
- Low Blood Sugar (Hypoglycemia): Severe blood sugar levels drop, often seen in individuals with diabetes, trigger seizures.
- Certain Medications: Some medications, including certain antidepressants and antipsychotics, lower the seizure threshold and trigger seizures.
- Specific Stimuli: Certain smells, sounds, or tastes trigger seizures in some individuals. This phenomenon is known as reflex epilepsy.
Individuals with epilepsy must identify and avoid their specific triggers whenever possible. This significantly helps manage and reduce the frequency of seizures. Keeping a seizure diary, which records events, activities, sleep patterns, and other factors, helps identify potential triggers and patterns. Additionally, working closely with a healthcare provider or neurologist is essential in managing epilepsy effectively.
What are the most effective seizure prevention strategies?
Managing epilepsy and preventing seizures often involves a combination of strategies tailored to the individual's specific needs and triggers. Here are some of the most effective seizure prevention strategies:
- Medication Adherence: Taking prescribed anti-epileptic medications regularly and as directed by a healthcare provider is fundamental in preventing seizures. Medications help stabilize electrical activity in the brain.
- Identifying Triggers: Identifying and avoiding specific triggers, such as lack of sleep, stress, or flashing lights, reduces the risk of seizures. Keeping a seizure diary to track activities and potential triggers is helpful.
- Healthy Lifestyle: Maintaining a regular sleep schedule, managing stress through relaxation techniques or counseling, and adopting a healthy diet and regular exercise routine contribute to overall well-being and help manage seizures.
- Avoiding Alcohol and Recreational Drugs: Alcohol and certain recreational drugs lower the seizure threshold. Avoiding these substances reduces the risk of seizures.
- Seizure Response Plans: Developing and sharing a seizure response plan with family, friends, and coworkers ensure that people around the individual know how to assist during a seizure, minimizing potential injuries.
- Medication Review: Regularly reviewing medications with a healthcare provider is important to assess their effectiveness and potential side effects. Adjustments in dosage or changes to different medications may be necessary.
- Medical Identification: Wearing a medical alert bracelet or necklace that indicates the individual has epilepsy is essential in emergencies. It provides crucial information to healthcare professionals about the person's condition and medications.
- Vagus Nerve Stimulation (VNS) Therapy: VNS therapy is a treatment option that involves a small device implanted under the skin of the chest. It sends regular, mild pulses of electrical energy to the brain via the vagus nerve, potentially reducing the frequency and severity of seizures.
- Ketogenic Diet: In some cases, following a ketogenic diet, which is high in fats and low in carbohydrates, help control seizures, especially in individuals who do not respond well to medications.
