  https://pmc.ncbi.nlm.nih.gov/articles/PMC3867171/

  About 10% of seizures in children with epilepsy are typical absence seizures. Absence seizures have a significant impact on quality of life. […] About 10% of seizures in children with epilepsy are typical absence seizures, with genetic factors considered to be the main cause. Where they are the only manifestation of epilepsy, they generally resolve spontaneously by the age of 12 years. […] Annual incidence has been estimated at 0.7 to 4.6/100,000 people in the general population, and 6 to 8/100,000 in children aged 0 to 15 years. Prevalence is 5 to 50/100,000 people in the general population. Similar figures were found in the US (Connecticut) and in Europe-based (Scandinavia, France) population studies. Age of onset ranges from 3 to 13 years, with a peak at 6 to 7 years. […] In childhood absence epilepsy, in which typical absence seizures are the only type of seizures suffered by the child, seizures generally cease spontaneously by 12 years of age or sooner.

  Childhood absence epilepsy is a common pediatric epilepsy syndrome. The annual incidence rate of childhood absence epilepsy in children less than 15 years of age has been estimated between 6.3/100,000 and 8.0/100,000. Recruitment bias explains that the frequency of childhood absence epilepsy in childhood epilepsies has been differently assessed, ranging from 2.3% to 37.7% of cases. In two prospective community-based studies, prevalence of childhood absence epilepsy was 10% and 12.3% for children younger than 16 years of age with epilepsy. Among all cases of epilepsy in school-aged children, 10% to 17% are due to childhood absence epilepsy.

• #8 Absence seizure – Wikipedia

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

  Absence seizures are most common in children. They affect both sides of the brain. The incidence of absence seizures in the United States is 1.98 cases per 100,000 population. Absence seizures affect between 0.7 and 4.6 per 100,000 in the general population and 6 to 8 per 100,000 in children younger than 15 years. Childhood absence seizures account for 10% to 17% of all absence seizures. Onset is between 4 and 10 years and peaks at 5 to 7 years. It is more common in girls than in boys. […] Educational and behavioral problems are sequelae of frequent, unrecognized seizures. No deaths result directly from absence seizures. However, if an individual suffers an absence seizure while driving or operating dangerous machinery, a fatal accident may occur.

  Childhood absence epilepsy is defined as frequent daily absence seizures (pyknolepsy) in normal school age children. It accounts for 8%15% of all childhood epilepsies1 with an annual incidence of 4.78.0 per 100,000 children between the ages of 1 and 15 years. […] The EEG in CAE shows interictal fragments of generalized spike and wave (GSW) in 92% of sleep-deprived EEGs (41% while awake, 100% in sleep).2,6 These fragments have the morphology of GSW but may not have a generalized distribution. […] Children with CAE have significantly more absence seizures per day than are recognized. These frequent seizures, usually with severe loss of awareness, contribute to learning and behavior difficulties as well as accidents.9,10 Treatment with antiepileptic drugs (AEDs) results in beneficial effects on cognitive functioning in these children and is therefore recommended after an EEG confirms the diagnosis.

[…] Myoclonic absence seizures are very rare, probably accounting for 1% to 2% of absences in children. Though more common in children, typical absences also occur in approximately 10% of adults with epilepsies often combined with other types of generalized seizure. Exact prevalence of juvenile absence epilepsy is uncertain because of variable criteria. In adults older than 20 years, its prevalence may be around 2% to 3% of all epilepsies and around 8% to 10% of idiopathic generalized epilepsies.

  Childhood absence epilepsy (CAE) is a common epilepsy syndrome characterized by absence seizures affecting young children and representing 18% of all diagnosed cases of epilepsy in school-age children. […] CAE incidence is 6.38.0 cases per 100,000 per year, and it represents 18% of epilepsy in school-aged children. In a cohort study of children, the CAE prevalence was estimated between 0.4 and 0.7 per 1000 people. […] CAE, with some exceptions, is more frequent in girls than in boys (75 vs. 60%). Usual CAE onset is between 4 and 10 years of age with a peak at 57 years.

  The incidence of absence seizures in the United States is 1.98 cases per 100,000 population. […] Absence seizures are generally believed to be more common in females than in males. Up to two thirds of children with childhood absence epilepsy are girls. […] Absence epilepsy with myoclonus has a male predominance. […] The generalized idiopathic epilepsies have age-related onset. […] Onset of absence seizures in children with symptomatic generalized epilepsies depends on the underlying disorder. […] Childhood absence epilepsy onset is at age 48 years, with peak onset at age 67 years. […] Juvenile absence epilepsy onset is generally around puberty. […] Juvenile myoclonic epilepsy has a more varied age of onset (826 y), but 79% of patients have an onset between the ages of 12 and 18 years.

Absence status occurs in patients who have idiopathic generalized epilepsy with typical absences, and consists of generalized, nonconvulsive seizures characterized by impairment of awareness. Other intermittent manifestations include automatisms or subtle myoclonic, tonic, atonic, or autonomic phenomena. Persistent confusion or stupor are associated with characteristic 1- to 4-Hz spike-and-wave or polyspike-and-wave discharges on EEG, usually without other typical clinical manifestations of absence seizures. Absence status is rare among children in population-based studies (0% to 3%).

  Childhood absence epilepsy is defined as frequent daily absence seizures (pyknolepsy) in normal school age children. It accounts for 8%15% of all childhood epilepsies1 with an annual incidence of 4.78.0 per 100,000 children between the ages of 1 and 15 years. […] The EEG in CAE shows interictal fragments of generalized spike and wave (GSW) in 92% of sleep-deprived EEGs (41% while awake, 100% in sleep).2,6 These fragments have the morphology of GSW but may not have a generalized distribution. […] Children with CAE have significantly more absence seizures per day than are recognized. These frequent seizures, usually with severe loss of awareness, contribute to learning and behavior difficulties as well as accidents.9,10 Treatment with antiepileptic drugs (AEDs) results in beneficial effects on cognitive functioning in these children and is therefore recommended after an EEG confirms the diagnosis.

  Childhood Absence Epilepsy (CAE) accounts for 10-17% of all cases of epilepsy in school-aged children. In Sweden, the incidence of CAE was estimated at approximately 1 out of 12,500 to 15,873 children per year, being more common in females (50-75% of cases). […] CAE has a genetic polygenic basis. Some recurrent CNVs (e.g. 15q11.2, 15q13.3, and 16p13.11 microdeletions) and variants in some susceptibility genes contribute to polygenic risk/complex inheritance. […] Diagnosis relies on clinical and electroencephalographic features: typical seizure semiology associated with paroxysmal rhythmic 3-Hz (range 2.5-4 Hz) generalized spike-wave discharges (GSWD) with abrupt onset and offset and duration of 3-20s, appearing on a normal background EEG activity. […] Differential diagnosis includes epilepsy with myoclonic absences, epilepsy with eyelid myoclonia, juvenile absence epilepsy, other epilepsies or developmental and epileptic encephalopathies with absence seizures (e.g. GLUT1-DS) and epilepsies with focal impaired awareness behavior arrest seizures. […] Increased risk for first-degree relatives may exist.

• #82 Absence seizures in children

  https://pmc.ncbi.nlm.nih.gov/articles/PMC3867171/

  Absence seizures have a significant impact on quality of life. The episode of unconsciousness may occur at any time, and usually without warning. Affected children need to take precautions to prevent injury during absences, and should refrain from activities that would put them at risk if seizures occurred (e.g., climbing heights, swimming unsupervised, or cycling on busy roads). […] Ethosuximide, lamotrigine, and valproate are widely regarded as first-line drugs used in children with absence seizures.
