Absence seizure : Question and Answer

An absence seizure, also known as petit mal seizure, is a type of generalized seizure that primarily affects children but can also occur in adults. It is characterized by a sudden and brief loss of consciousness or awareness. Unlike other types of seizures, there is no convulsive activity or significant muscle movement during an absence seizure.

Here are some key characteristics of absence seizures:

  • Sudden Onset: Absence seizures often begin abruptly without warning.

  • Duration: They are typically very brief, lasting only a few seconds, but can last up to 20 seconds in some cases.

  • Lack of Awareness: During an absence seizure, the person appears to be staring blankly into space, and they are unaware of their surroundings. They may not respond to external stimuli, such as calling their name or tapping on their shoulder.

  • Minimal Movements: In most cases, there are no significant body movements during an absence seizure. However, some individuals may exhibit subtle movements like eye blinking or lip smacking.

  • Frequency: Absence seizures can occur multiple times a day, and a person may have many of them in a short period.

  • Postictal State: Unlike some other seizures, there is usually no postictal confusion or exhaustion following an absence seizure. The person typically resumes normal activity immediately after the seizure ends.

  • Triggers: Fatigue, stress, or flashing lights can sometimes trigger absence seizures in susceptible individuals.

How long do absence seizures last?

Absence seizures, also known as petit mal seizures, are a type of epileptic seizure that typically lasts for a short duration, usually just a few seconds. They are characterized by a sudden and brief loss of awareness and responsiveness, during which the person may appear to be staring blankly into space.

The duration of an absence seizure can vary from person to person, but they are generally quite brief, often lasting for 10 to 20 seconds. In some cases, they may be even shorter, lasting just a few seconds. After the seizure ends, the person usually resumes normal activities and may not have a clear memory of the episode.

It's important to note that while absence seizures are short in duration, they can occur frequently throughout the day, and individuals who experience them may require medical evaluation and treatment, often with antiepileptic medications, to manage their condition and prevent further seizures. It's crucial for individuals with epilepsy or suspected seizures to consult with a healthcare professional for proper diagnosis and treatment.

How common are absence seizures?

The exact prevalence of absence seizures can vary depending on the population studied and the geographical region, but they are generally considered relatively common among childhood epilepsy syndromes.

Here are some key points about the prevalence of absence seizures:

  • Childhood Epilepsy: Absence seizures are most commonly associated with childhood epilepsy. They often begin in early childhood, typically between the ages of 4 and 12, but they can start earlier or later.

  • Prevalence in Childhood Epilepsy: In children with epilepsy, absence seizures account for a significant proportion of cases. It is estimated that they make up about 10-15% of all childhood epilepsy cases.

  • Higher in Girls: Absence seizures are more common in girls than in boys. The exact gender ratio can vary, but generally, girls are affected more often.

  • Decrease in Prevalence with Age: As individuals with absence seizures reach adolescence and adulthood, these seizures often decrease in frequency or may even stop altogether. Some individuals may continue to have absence seizures into adulthood, but they are less common in older age groups.

  • Geographical Variations: The prevalence of absence seizures can vary from one region to another. Studies have shown differences in prevalence rates among different countries and ethnic groups.

It's essential to note that while absence seizures are relatively common among childhood epilepsy syndromes, they can vary in severity and may respond well to medication in many cases. Effective management, including the use of antiepileptic drugs, can often control or even eliminate these seizures, allowing individuals to lead normal lives.

What activities should my child with absence seizure avoid?

It's essential to consult with a healthcare professional, ideally a pediatric neurologist, for personalized advice tailored to your child's specific condition and needs. Absence seizures, also known as petit mal seizures, are characterized by brief lapses in consciousness and can occur without warning. Here are some activities and precautions to consider:

  • Contact Sports: High-impact sports like football, boxing, or rugby may pose a risk due to the possibility of head injuries. Instead, consider lower-impact activities such as swimming, cycling, or tennis, which can be safer.

  • Swimming Alone: If your child has absence seizures, they should avoid swimming without supervision. Seizures in the water can be extremely dangerous.

  • Bathing: Young children may need supervision during baths to prevent accidents, especially if absence seizures are frequent.

  • Climbing Heights: Activities like rock climbing or tree climbing can be risky due to the potential for falls. Ensure proper safety measures and supervision if your child wants to engage in these activities.

  • Operating Heavy Machinery: Children should not operate heavy machinery or vehicles that require full attention, such as cars or motorcycles, if they have uncontrolled absence seizures.

  • Excessive Screen Time: Prolonged screen time, particularly with flashing or flickering lights, can trigger seizures in some individuals. It's important to monitor your child's screen time and provide breaks.

  • Sleep Deprivation: Lack of sleep can increase the likelihood of seizures. Encourage a consistent sleep schedule and ensure your child gets adequate rest.

  • Stress Management: Stress and anxiety can be seizure triggers for some individuals. Help your child learn stress-reduction techniques like mindfulness, yoga, or deep breathing exercises.

  • Alcohol and Recreational Drugs: Adolescents should avoid alcohol and recreational drugs, as they can lower seizure threshold and interact negatively with seizure medications.

  • Strobe Lights: Avoid environments with flashing or strobe lights, such as certain parties or events, as they can trigger seizures in some individuals with epilepsy.

  • Hot Baths or Showers: Extremely hot baths or showers can lead to overheating, which might trigger seizures. Ensure the water temperature is safe.

  • Overexertion: Prolonged physical activity, especially in hot weather, can lead to overheating and dehydration, potentially triggering seizures. Encourage adequate hydration and rest breaks during physical activities.

It's crucial to work closely with your child's healthcare team, which may include a pediatric neurologist, to develop a seizure management plan tailored to their specific needs. This plan may involve medication, lifestyle modifications, and regular follow-up appointments to monitor their condition. Additionally, ensure that teachers, caregivers, and other relevant individuals are aware of your child's condition and how to respond in case of a seizure.

What can I expect if my child has an absence seizure?

If your child has been diagnosed with absence seizures, it's essential to understand what to expect and how to manage this condition. Absence seizures, also known as petit mal seizures, are a type of epilepsy that primarily affects children. Here are some things you can expect:

  • Sudden Onset and Brief Duration: Absence seizures typically come on suddenly and last for a very short period, usually less than 15 seconds. During this time, your child may appear to be staring into space and become unresponsive.

  • Frequency: The frequency of absence seizures can vary from child to child. Some children may have multiple seizures per day, while others might have them less frequently.

  • No Warning Signs: Absence seizures often occur without any warning signs or auras. They can happen at any time during the day, and your child may not be aware that they are experiencing a seizure.

  • Behavior During Seizure: During an absence seizure, your child may exhibit some of the following behaviors:

    • Staring blankly into space

    • Momentarily stopping activity or speech

    • Eyelid fluttering

    • Lip-smacking or chewing motions

    • Hand movements such as rubbing or fumbling

    • Small, involuntary movements of the head or body

  • Loss of Awareness: Your child will lose awareness of their surroundings during the seizure and will not remember what happened during that time.

  • Duration of Condition: Absence seizures often begin in childhood and may continue into adolescence or resolve on their own as a child gets older. In some cases, they may persist into adulthood.

  • Impact on Learning: Absence seizures can disrupt your child's concentration and learning. They may miss parts of a lesson or conversation during a seizure. As a result, it's essential to communicate with your child's school and teachers to ensure they receive appropriate support.

  • Safety Concerns: Safety is a significant concern during absence seizures. Ensure that your child is not engaged in activities that could be dangerous when a seizure occurs, such as swimming or climbing. Consider discussing this with teachers, caregivers, and other responsible adults.

  • Medication: Absence seizures are often treated with antiepileptic medications prescribed by a neurologist. The choice of medication will depend on your child's specific needs and the neurologist's recommendations. It's crucial to administer the medication as prescribed and to attend follow-up appointments.

  • Lifestyle and Support: Creating a supportive environment is essential for children with absence seizures. This may involve educating family members, teachers, and caregivers about the condition, ensuring your child gets enough sleep, managing stress, and following a consistent routine.

  • Regular Medical Follow-up: Your child will need regular check-ups with a neurologist to monitor their condition and adjust their medication if necessary. It's important to keep these appointments and communicate any changes in seizure activity or side effects of medication.

Remember that every child is unique, and the experience of absence seizures can vary. It's crucial to work closely with your child's healthcare team to develop an individualized treatment plan and provide the necessary support to help your child manage their condition effectively. With the right care and management, many children with absence seizures lead normal, healthy lives.

Who are the doctors who treat Absence seizures?

They are usually treated by neurologists, epileptologists, and pediatric neurologists. These doctors have specialized training in diagnosing and managing various types of seizures and epilepsy, including absence seizures.

Here are some of the healthcare professionals who may be involved in the treatment of individuals with absence seizures:

  • Neurologist: A neurologist is a medical doctor who specializes in the diagnosis and treatment of disorders of the nervous system, including epilepsy and seizures.

  • Pediatric Neurologist: Pediatric neurologists are neurologists who have additional training in treating children with neurological conditions, including childhood epilepsy and absence seizures.

  • Epileptologist: An epileptologist is a neurologist with specialized expertise in epilepsy. They often work in epilepsy centers and have extensive experience in diagnosing and managing epilepsy, including absence seizures.

  • Neuropsychiatrist: In cases where absence seizures are associated with behavioral or psychiatric issues, a neuropsychiatrist may be involved in the treatment plan. They can help address any comorbid psychiatric conditions.

  • Nurse Practitioner or Physician Assistant: In some healthcare settings, nurse practitioners or physician assistants may work alongside neurologists to help manage epilepsy and seizure disorders. They can assist with medication management and patient education.

  • EEG Technologist: Electroencephalogram (EEG) technologists are trained to perform EEG tests, which are crucial in diagnosing and monitoring epilepsy and absence seizures. They work under the supervision of neurologists or epileptologists.

Treatment for absence seizures typically involves antiepileptic medications, such as ethosuximide, valproic acid, or lamotrigine. The choice of medication and treatment plan will depend on the individual patient's specific condition and medical history. In some cases, other therapies, such as lifestyle modifications or dietary interventions, may also be recommended.

It's essential for individuals with absence seizures to work closely with their healthcare team to receive proper diagnosis and ongoing care to effectively manage their condition and improve their quality of life.

What is the drug of choice for Absence seizures?

The drug of choice for treating absence seizures, also known as petit mal seizures, is generally Ethosuximide or Valproic Acid (valproate). These medications are considered first-line treatments for absence seizures, but the choice between them depends on various factors, including the patient's age, medical history, and individual response to the drugs.

  • Ethosuximide: Ethosuximide is often the preferred initial treatment for absence seizures, especially in children and individuals without other types of seizures. It works by reducing abnormal electrical activity in the brain, which is characteristic of absence seizures. Ethosuximide typically has fewer side effects compared to some other antiepileptic medications.

  • Valproic Acid (Valproate): Valproic acid, also known as valproate, is another effective option for treating absence seizures. It is sometimes preferred when patients have multiple seizure types or when absence seizures are associated with other seizure disorders. Valproate can have a broader spectrum of action against different seizure types but may have more side effects than ethosuximide.

The choice of medication should be made by a healthcare provider after a thorough evaluation of the patient's specific condition and medical history. Factors such as age, gender, the presence of other medical conditions, potential drug interactions, and individual response to the medication all play a role in determining the most appropriate treatment.

It's crucial for individuals with epilepsy, including absence seizures, to work closely with their healthcare provider to find the right medication and dosage to effectively manage their condition while minimizing side effects. Additionally, regular follow-up appointments and monitoring are essential to assess treatment efficacy and make any necessary adjustments.
