Do absence seizures have long-term effects?
Absence seizures are most common in children and typically don’t cause any long-term problems. These types of seizures are often set off by a period of hyperventilation.
What are the long-term after effects of a seizure?
Long lasting seizures, or status epilepticus, may also cause brain damage or death. People with epilepsy are eight times more likely than people without it to experience certain other chronic conditions, including dementia, migraine, heart disease, and depression.
How long does it take your brain to recover from a seizure?
As the seizure ends, the postictal phase occurs – this is the recovery period after the seizure. Some people recover immediately while others may take minutes to hours to feel like their usual self.
Can absence seizures return in adulthood?
Absence seizures are most common in children and adolescents. They can also start in adulthood. This is called an adult new-onset seizure.
How do you feel after an absence seizure?

Absence seizures. This kind of seizure will only last a few seconds, and the person experiencing it will typically not realize that they even had it. Absence seizures do not require any intervention. Just stay calm, and once the seizure is over, treat the person as you normally would.
Can Absence seizures cause brain damage?
While absence seizures occur in the brain, they don’t cause brain damage. Absence seizures won’t have any effect on intelligence in most children. Some children may experience learning difficulties because of their lapses in consciousness.
What kind of brain damage can seizures cause?
Seizures, particularly repetitive seizures, cause substantial brain damage in highly susceptible areas, such as parts of the hippocampus, entorhinal cortex, amygdala, thalamus and other limbic structures; however, neuronal death after seizures can be more widespread and is generally quite variable (e.g., [24, 77]).
Is it normal to have memory loss after a seizure?
You may have difficulty remembering information straight after a seizure. This is sometimes called post-ictal confusion and it usually goes away once you have recovered. The length of time it takes for memory to return to normal can vary from person to person.
Do absence seizures cause memory loss?
Furthermore, frequent recurrent seizures, even in the absence of neuronal injury, may lead to the decline of learning and memory. It is also possible that chronic, persistent dysfunction of limbic circuits, which is characteristic of epilepsy, may impair memory even in the absence of neuronal injury and seizures.
How long do absence seizures last in children?
Childhood Absence Epilepsy. Each seizure lasts about 10 to 20 seconds and ends abruptly. These types of seizures account for 1 to 4 out of 50 people with epilepsy (2 to 8\%). The cause is mostly genetic. Two out of 3 children with childhood absence seizures respond to treatment. The seizures usually disappear by mid-adolescence.

The person returns to normal behavior after the seizure. The person usually doesn’t remember the past few moments or the seizure itself. Some absence seizures can last up to 20 seconds. While absence seizures occur in the brain, they don’t cause brain damage.
What are the symptoms of absence status epilepticus?
If you observe prolonged automatic behaviors lasting minutes to hours — activities such as eating or moving without awareness — or prolonged confusion, possible symptoms of a condition called absence status epilepticus Many children appear to have a genetic predisposition to absence seizures.
