  https://www.ncbi.nlm.nih.gov/books/NBK499867/

  Absence seizures are classified as a type of generalized onset nonmotor seizure with clinical symptoms, including unresponsiveness and staring spells. Absence seizures are generally seen in children aged 5 to 15 years and occur in multiple genetic generalized epilepsies, including childhood absence epilepsy (CAE), juvenile absence epilepsy (JAE), and juvenile myoclonic epilepsy (JME). […] While primarily affecting children, absence seizures can persist into adulthood, significantly impacting daily functioning and quality of life if left untreated. […] Absence seizures are brief seizures characterized by a behavioral arrest correlating with generalized 3-Hz spike and wave discharges on electroencephalogram (EEG). […] Absence seizures have often been considered „benign” due to their nonconvulsive nature; however, up to 60% of children with absence seizures have severe neuropsychic manifestations, including disturbances in attention, cognition, memory, and mood.

• #2 Absence seizure – Wikipedia

  https://en.wikipedia.org/wiki/Absence_seizure

  Absence seizures are characterized by a brief loss and return of consciousness, generally not followed by a period of lethargy (i.e. without a notable postictal state). […] The clinical manifestations of absence seizures vary significantly among patients. Impairment of consciousness is the essential symptom, and may be the only clinical symptom, but this can be combined with other manifestations. The hallmark of the absence seizures is abrupt and sudden-onset impairment of consciousness, interruption of ongoing activities, a blank stare, possibly a brief upward rotation of the eyes. […] Mixed forms of absence frequently occur. These seizures can happen a few times a day or in some cases, hundreds of times a day, to the point that the person cannot concentrate in school or in other situations requiring sustained, concentrated attention.

• #3 Absence seizure – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/petit-mal-seizure/symptoms-causes/syc-20359683

  Absence seizures involve brief, sudden lapses of consciousness. They’re more common in children than in adults. […] A person having an absence seizure may stare blankly into space for a few seconds. Then the person typically returns quickly to being alert. This type of seizure usually doesn’t lead to physical injury. But injury can happen if someone is driving a car or riding a bike when the seizure happens. […] A simple absence seizure causes a vacant stare, which may be mistaken for a brief lapse in attention. The seizure lasts about 10 seconds, though it may last as long as 30 seconds. There’s no confusion, headache or drowsiness after the seizure. […] Symptoms of absence seizures include: A sudden stop in activity without falling. Lip smacking. Eyelid flutters. Chewing motions. Finger rubbing. Small movements of both hands.

• #4 Absence Seizure – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK499867/

  The age of onset of CAE is usually between 4 and 10 years, with a peak between the ages of 5 and 7. […] Regarding the clinical presentation, family members and teachers usually describe brief spells in which the child has a loss of awareness, is unresponsive, and has a behavioral arrest. Bystanders often describe the patient during these spells as having a blank stare. Episodes frequently occur, often 10 to 30 times throughout the day. […] Spells usually last between 4 and 30 seconds. […] These seizures are not preceded by an aura and do not have a postictal state. […] The first-line treatment for absence epilepsy is ethosuximide. […] Approximately 60% of patients with CAE eventually achieve seizure freedom.

• #5 A Practical Guide to Treatment of Childhood Absence Epilepsy

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6394437/

  Childhood absence epilepsy (CAE) is a common pediatric epilepsy syndrome with distinct seizure semiology, electroencephalography (EEG) features, and treatment. Seizures usually begin between 4 and 10 years of age, with a peak around 6-7 years, in a previously healthy and typically developing child. Seizures occur many times daily and consist of brief staring spells, sometimes with rhythmic eye blinking or motor automatisms, lasting seconds, with immediate return to the baseline level of awareness and activity. On electroencephalography (EEG), seizures are characterized by a highly recognizable pattern of generalized (bilateral, symmetric and synchronous) 3 Hz spike and wave discharges. […] Absence seizures typically cause sudden cessation of activity that is easily recognizable. Elements of history that suggest absence seizures include sudden loss of facial expression; repetitive movements (such as lip smacking or blinking); events occurring regardless of setting (not only while watching television or in the car for example, where staring is more likely behavioral); and events that occur in the midst of an activity such as chewing or playing.

• #6 Absence (Petite Mal) Seizures: Symptoms, Risk, and Causes

  https://www.healthline.com/health/epilepsy/absence-petit-mal-seizures

  Petit mal or absence seizures most commonly affect young children younger than 12, but can also affect adults. Absence seizures tend to cause shorter and milder symptoms than grand mal seizures. […] Absence seizures, sometimes called petit mal seizures, are brief, usually lasting less than 20 seconds. They cause symptoms that may be barely noticeable. People having these seizures may appear like theyre daydreaming or zoning out. […] According to the Epilepsy Foundation, an advocacy group, absence seizures generally last less than 10 to 20 seconds. Typical symptoms include: staring off into space, smacking the lips together, fluttering eyelids, stopping speech in the middle of a sentence, making sudden hand movements, leaning forward or backward, appearing suddenly motionless. […] You can often tell if a person is experiencing an absence seizure because they become unaware of their surroundings, touch, and sound. Absence seizures typically occur suddenly and with no warning. This makes taking precautions to protect the person having a seizure important.

• #10 Absence Seizures | Kettering Health

  https://ketteringhealth.org/conditions/absence-seizures/

  The easiest way to spot an absence seizure is to look for a blank stare that lasts for a few seconds. People in the midst of having an absence seizure don’t speak, listen, or appear to understand. An absence seizure doesn’t typically cause you to fall down. You could be in the middle of making dinner, walking across the room, or typing an e-mail when you have the seizure. Then suddenly you snap out of it and continue as you were before the seizure. […] These are other possible symptoms of an absence seizure: Being very still, Smacking the lips or making a chewing motion with the mouth, Fluttering the eyelids, Stopping activity such as suddenly not talking or moving, Suddenly returning to activity when the seizure ends. […] Most absence seizures last less than 15 seconds. It’s rare for an absence seizure to last longer than 15 minutes. They can happen suddenly without any warning signs.

  An absence seizure is a type of generalized seizure. During this type of seizure, the person is not aware of what is going on around them. Someone who is having an absence seizure suddenly stops what they are doing and stares into space. They also might: open and close their lips subtly or make chewing motions […] Someone can have many absence seizures in a day. They dont remember having the seizures, but older kids may realize that they lost time around them. These seizures often may be mistaken for daydreaming or inattention. Absence seizures usually last about 20 seconds. After the seizure, most children return to what they were doing just before the seizure started as if nothing happened. But they won’t recall what just happened, or if someone talked to them during the seizure. Rarely, a child might feel confused or tired, have a headache, or have other symptoms. This is called the postictal (post-IK-tul) phase. It usually lasts just a few minutes, but can be longer. This phase can happen if a child has many absence seizures in one day or they happen too close together.

This type of seizure usually doesn’t lead to physical injury. But injury can happen if someone is driving a car or riding a bike when the seizure happens. […] A simple absence seizure causes a vacant stare, which may be mistaken for a brief lapse in attention. The seizure lasts about 10 seconds, though it may last as long as 30 seconds. There’s no confusion, headache or drowsiness after the seizure. […] Symptoms of absence seizures include: A sudden stop in activity without falling. Lip smacking. Eyelid flutters. Chewing motions. Finger rubbing. Small movements of both hands.

  Absence seizures are short seizures that happen without warning and usually last for a few seconds. They typically start without warning and last between three and 15 seconds. Absence seizure symptoms are temporary but can stop you in your tracks. The symptoms of absence seizures include: Brief sudden staring spell or blank stare. Loss of awareness. Complete stop in activity during the seizure (like talking or walking). Occasional eyelid fluttering or nodding of the head or other automatic hand or mouth movements (like lip smacking). […] After the seizure, you may: Continue doing the activity that you stopped doing during the seizure. Feel that you missed things happening around you. Not notice that anything happened, and feel awake and like you’re thinking clearly. Absence seizure symptoms can happen several times per day or occasionally for weeks to months.

• #39 Absence and Atypical Absence Seizures – LGS Foundation

  https://www.lgsfoundation.org/atypical-absence-seizures/

  Absence Seizures cause lapses in awareness and sometimes involve staring. These used to be called petit mal seizures. They begin abruptly and only last a few seconds. They are common in children and may be mistaken for daydreaming. The person will stare but they may be able to respond a bit. […] Symptoms of absence seizures can be difficult to pick up in a person with other cognitive or behavioral problems. It may be hard to tell what is due to a seizure or other behaviors. These seizures may begin and end gradually. This is different from the sudden start and stop of a typical absence seizure. Falling during a seizure is also more common than it is during typical absence seizures. Atypical absence seizures usually last 5 to 30 seconds and can occur in clusters. […] Absence and atypical absence seizures are very difficult to identify without a video EEG. Pediatric epilepsy specialists who reviewed this video agreed this is a good example of an atypical absence seizure with myoclonic activity. […] An EEG is the only way to determine the exact seizure type.

  On average, typical absence seizures last between three and 15 seconds. Atypical absence seizures can last longer. […] Even though they’re short, absence seizures can be very distracting. You may not have many or they can be frequent. Some people report having 10 to more than 30 absence seizures a day. The frequency can reach into the hundreds per day, especially among children. They can interfere with your ability to learn and focus on a task. But treatment options are available, and medications are usually successful at managing symptoms.

  https://www.health.harvard.edu/a_to_z/absence-seizures-petit-mal-seizures-a-to-z

  An absence seizure causes a loss of consciousness for 30 seconds or less. It is barely noticeable, if at all. The person simply stops moving or speaking. He or she stares straight ahead blankly, and does not respond to questions. The seizure is short and hard to notice. A person can have 50 or 100 absence seizures a day, without them being detected. […] After the seizure ends, the child has no memory of the episode. He or she usually resumes previous activities as if nothing happened. There usually is no confusion or recovery period after an absence seizure. […] A child with absence epilepsy can have many brief seizures during a school day. As a result, the disorder may interfere seriously with their ability to pay attention and participate in class. […] Outside the classroom, the child’s symptoms may affect the ability to concentrate when he or she plays sports or does homework. Seizures also may interrupt conversations with friends or family members.

• #42 Absence seizure – Wikipedia

  https://en.wikipedia.org/wiki/Absence_seizure

  Absence seizures are characterized by a brief loss and return of consciousness, generally not followed by a period of lethargy (i.e. without a notable postictal state). […] The clinical manifestations of absence seizures vary significantly among patients. Impairment of consciousness is the essential symptom, and may be the only clinical symptom, but this can be combined with other manifestations. The hallmark of the absence seizures is abrupt and sudden-onset impairment of consciousness, interruption of ongoing activities, a blank stare, possibly a brief upward rotation of the eyes. […] Mixed forms of absence frequently occur. These seizures can happen a few times a day or in some cases, hundreds of times a day, to the point that the person cannot concentrate in school or in other situations requiring sustained, concentrated attention.

• #43 Absence Seizures: Overview, Etiology, Epidemiology

  https://emedicine.medscape.com/article/1183858-overview

  The generalized idiopathic epilepsies have age-related onset. Onset of absence seizures in children with symptomatic generalized epilepsies depends on the underlying disorder. While many of these disorders may have their onset at an early (prenatal, perinatal, or postnatal) age, absence seizures do not appear until later in childhood. An example is the Lennox-Gastaut syndrome. The cause may be a genetic disorder or a perinatal insult, but the absence seizures do not present until age 18 years. […] Childhood absence epilepsy onset is at age 48 years, with peak onset at age 67 years. Juvenile absence epilepsy onset is generally around puberty. Actual age of onset may vary, depending on whether pyknoleptic or nonpyknoleptic seizures occur. Juvenile myoclonic epilepsy has a more varied age of onset, but 79% of patients have an onset between the ages of 12 and 18 years. Because the absence and myoclonic seizures are brief, they often go unrecognized, and many patients do not present until they experience a tonic-clonic seizure.

• #44 Absence Seizures: Overview, Etiology, Epidemiology

  https://emedicine.medscape.com/article/1183858-overview

  Absence seizures occur in idiopathic and symptomatic generalized epilepsies. Among the idiopathic generalized epilepsies, absence seizures are seen in childhood absence epilepsy (pyknolepsy), juvenile absence epilepsy, and juvenile myoclonic epilepsy. The seizures in these conditions are called typical absence seizures and are usually associated with generalized 3-4 Hz spike-and-slow-wave complexes on EEG. […] In childhood absence epilepsy, seizures are frequent and brief, lasting just a few seconds (pyknoleptic). Some children can have many such seizures per day. In other epilepsies, particularly those with an older age of onset, the seizures can last several seconds to minutes and may occur only a few times a day; these are called nonpyknoleptic or spanioleptic absence seizures. […] In the cryptogenic or symptomatic generalized epilepsies, absence seizures are often associated with slow spike-wave complexes of 1.5-2.5 Hz; these are also called sharp-and-slow-wave complexes. These seizures may be associated with loss of axial tone and head nodding; a fall may occur. Increased tone, autonomic features, and automatisms may also be seen. Absence seizures associated with slow spike-wave complexes are called atypical absence seizures.

  Absence seizures typically become less frequent over time. Childhood absence epilepsy and other causes of absence seizures rarely continue into adulthood. […] Most absence seizures last a few seconds before the person makes an immediate recovery. Some children will experience as many as 50-100 absence seizures in a day. […] Absence seizures cause a short lapse in consciousness. Experiencing multiple seizures throughout the day can be confusing and cause problems at school or when socializing with friends. […] The outlook for absence seizures varies depending on their frequency and severity. In most cases, the child will stop experiencing absence seizures by adulthood. […] In other cases, children may require long-term medications to treat their absence seizures. Ongoing treatment can help prevent seizures and reduce their impact on the person’s daily life.

Not all people experience this stage. Some common signs can include: Mood changes, Anxiety, Feeling lightheaded, Difficulty sleeping, Difficulty staying focused, Behaviour changes. […] Auras are generally considered an early part of the seizure. Symptoms of an aura may include: D déjà vu (a sense that something has happened before when in fact it hasn’t), Jamais vu (a feeling that you’re seeing something you know well for the first time), Odd smells, sounds or tastes, Dizziness, Vision difficulties, Numbness or ‘pins and needles’ in parts of the body, Nausea, Headache, Panic, Feelings of intense fear. […] The middle (ictal) stage of a seizure is called the ictal phase. It’s the time from the first symptom to the end of the seizure activity. It is during this time that intense electrical activity is occurring in the brain. Some common signs of this phase include: Loss of awareness, Memory lapse, Feeling confused, Difficulty hearing, Odd smells, sounds or tastes, Difficulty speaking or saying strange words, Twitching, Loss of muscle control, Repeated movements (such as lip smacking or chewing), Body convulsions, Racing heart, Trouble breathing.

[…] A blank, vacuous gaze is typical throughout the episode, often accompanied by eye blinking or little movements. […] The person may not recollect the seizure afterward. […] Absence seizures, or petit mal seizures, are short episodes of altered consciousness, frequently manifesting as a blank stare and lack of awareness. […] These seizures, common in epilepsy, can significantly disrupt day-by-day lifestyles, although they appear minor. […] They represent 2-5% of all epilepsy cases and primarily affect children between the ages of 4 and 14. […] Absence seizures are often triggered with the aid of genetic elements, brain abnormalities, or metabolic imbalances including low blood sugar.

[…] Seizures are unlikely to impact upon the development of the affected child. However, children who experience a high frequency of seizures may develop some learning difficulties. […] Good to know: It is possible for children to be affected by atypical absence seizures. This less common type of seizure tends to begin and end more gradually than a typical absence seizure. Generally, they also last longer, though they can last anywhere between 5 and 30 seconds. […] The prognosis for childhood absence epilepsy is very good. Through the use of medication, approximately 70 percent of children with the condition will have their seizures completely controlled by mid-adolescence. In around 10 percent of cases, children with CAE will develop other types of seizures in adolescence, most commonly clonic-tonic seizures.

  https://www.webmd.com/epilepsy/understanding-absence-seizure-basics

  Affecting about two of every 1,000 people, absence seizures (formerly called ”petit mal” seizures) are caused by abnormal and intense electrical activity in the brain. […] Typically, this type of seizure lasts between 10 and 30 seconds. The person, most often a child aged 5 to 15, abruptly stops whatever they’re doing (talking, walking) and appears to „stare into space.” Absence seizures rarely cause a true convulsion in which the person falls down or collapses. Despite briefly losing consciousness, the person recovers fully with no lingering confusion or other ill effects. These „spells” may occur infrequently or several times per hour. In children, absence seizures may interfere with learning and are often misinterpreted as daydreaming or inattention. About a quarter of people who have absence seizures will develop another type of generalized seizure called tonic-clonic seizures (formerly called ”grand mal” seizures). The vast majority of children, however, will outgrow them.

  An absence seizure causes a loss of consciousness for 30 seconds or less. It is barely noticeable, if at all. The person simply stops moving or speaking. He or she stares straight ahead blankly, and does not respond to questions. The seizure is short and hard to notice. A person can have 50 or 100 absence seizures a day, without them being detected. […] After the seizure ends, the child has no memory of the episode. He or she usually resumes previous activities as if nothing happened. There usually is no confusion or recovery period after an absence seizure. […] A child with absence epilepsy can have many brief seizures during a school day. As a result, the disorder may interfere seriously with their ability to pay attention and participate in class. […] Outside the classroom, the child’s symptoms may affect the ability to concentrate when he or she plays sports or does homework. Seizures also may interrupt conversations with friends or family members.

  An absence seizure is a seizure where you lose consciousness and stare blankly for a few seconds. You then regain consciousness and carry on as you were before. You will not be aware that you had a seizure, but may feel confused. […] Absence seizures symptoms include: Blank stares that last a few seconds, before you carry on as before. You usually wont fall down. You will not speak, listen or understand what people are saying to you. You may stop speaking mid sentence. Sometimes you might smack your lips, look like you are chewing something or flutter your eyelids. […] Absence seizures in children can be challenging because they make it harder to pay attention at school. Children with absence seizures sometimes start misbehaving because they are feeling confused or frustrated. Teachers may also misunderstand what is happening and think the child is simply not focusing.

  Atypical absence seizures, which occur in patients with symptomatic generalized epilepsies, are usually longer than typical absences and often have more gradual onset and resolution. In symptomatic generalized epilepsies, physical and neurologic findings may be abnormal, reflecting the underlying disorder. […] The prognosis for the primary generalized epilepsies depends on the particular epileptic syndrome. Because seizures, particularly generalized tonic-clonic seizures, may occur well after patients appear to achieve good control, a long seizure-free period should be achieved before discontinuation of therapy is considered. […] The remission rate for childhood absence epilepsy is good; 80% of patients respond to medication. Complete remission rates vary widely, perhaps dependent on the length of follow-up. Generalized tonic-clonic seizures may develop in up to 40% of children with childhood absence epilepsy. Persistence of seizures is more likely in those with generalized tonic-clonic seizures. Early onset of absence seizures, quick response to therapy, and normal EEG background are good prognostic signs.

  https://www.cincinnatichildrens.org/health/j/juvenile-absence-epilepsy

  Juvenile absence epilepsy (JAE) is a type of epilepsy that causes absence (ab-SONCE) seizures. During a seizure, the child will stare and stop what they are doing. They may blink quickly or move their hands. They may look like they are daydreaming or not paying attention. These seizures last only a few seconds. Absence epilepsy is sometimes called petit mal epilepsy. […] JAE seizures usually involve staring spells. The child is not aware or responsive during these spells. You may also notice: The child’s eyes may roll up briefly. Each seizure episode lasts seconds. The child goes back to normal right away. The child often doesn’t realize a seizure has happened. […] A small number of children with JAE epilepsy will have one or more episodes of absence status epilepticus. This is when an absence seizure lasts for several hours or even a day or more. Absence status epilepticus is a medical emergency. The child needs rescue medication to stop the seizure. […] Children typically do not grow out of JAE. The condition lasts into adulthood. However, many people can control the seizures with medication.

  Typical absence seizure: behavioral arrest or staring, lasting 5 to 10 seconds, interrupting otherwise normal activity. Can be hyperventilation-induced. […] Atypical absence seizures: less distinct beginning and end, not usually precipitated by hyperventilation. […] Most typical absence seizures are medically responsive, and childhood absence epilepsy (CAE) tends to remit by adulthood. […] Atypical absence seizures tend to be medically refractory and associated with intellectual disability. […] Typical absence seizures are approximately 5 to 10 seconds in duration, have minimal, if any, postictal confusion, and are usually precipitated by hyperventilation and sometimes by photic stimulation. […] Atypical absence seizures have a less distinct beginning and end and are not usually precipitated by hyperventilation or photic stimulation, and the EEG shows generalized slow (2.5 Hz) spike-and-wave with a diffusely slow background. […] The classic epilepsy syndrome with atypical absence seizures is Lennox-Gastaut syndrome, characterized by multiple seizure types (severe tonic seizures, myoclonic-atonic seizures, and absence seizures), intellectual disability, and slow spike-and-wave on EEG.

  https://www.webmd.com/epilepsy/understanding-absence-seizure-basics

  Affecting about two of every 1,000 people, absence seizures (formerly called ”petit mal” seizures) are caused by abnormal and intense electrical activity in the brain. […] Typically, this type of seizure lasts between 10 and 30 seconds. The person, most often a child aged 5 to 15, abruptly stops whatever they’re doing (talking, walking) and appears to „stare into space.” Absence seizures rarely cause a true convulsion in which the person falls down or collapses. Despite briefly losing consciousness, the person recovers fully with no lingering confusion or other ill effects. These „spells” may occur infrequently or several times per hour. In children, absence seizures may interfere with learning and are often misinterpreted as daydreaming or inattention. About a quarter of people who have absence seizures will develop another type of generalized seizure called tonic-clonic seizures (formerly called ”grand mal” seizures). The vast majority of children, however, will outgrow them.

[…] Most absence seizures last a few seconds before the person makes an immediate recovery. Some children will experience as many as 50-100 absence seizures in a day. […] Absence seizures cause a short lapse in consciousness. Experiencing multiple seizures throughout the day can be confusing and cause problems at school or when socializing with friends. […] The outlook for absence seizures varies depending on their frequency and severity. In most cases, the child will stop experiencing absence seizures by adulthood.
