Absence Seizures: What You Need to Know

What are absence seizures?

Absence seizures, also known as petit mal seizures or childhood absence epilepsy, are a type of generalized non-motor seizure. This means that they begin in both sides of the brain at the same time. Absence seizures cause a brief lapse in awareness, typically lasting only 5 to 10 seconds. During a seizure, the person may stare blankly or appear to be daydreaming. They may also stop whatever they are doing and resume it afterwards without any recollection of the seizure.

What are the symptoms of absence seizures?

The most common symptom of an absence seizure is a brief lapse in awareness. Other symptoms may include:

• Staring
• Blank expression
• Eye blinking
• Lip smacking
• Head nodding
• Body stiffening
• Loss of consciousness

What causes absence seizures?

The exact cause of absence seizures is unknown. However, they are thought to be caused by abnormal electrical activity in the brain. Absence seizures are most common in children between the ages of 4 and 12. They tend to run in families, which suggests that there may be a genetic component to the disorder.

How are absence seizures treated?

Absence seizures are typically treated with medication. The most common medications used to treat absence seizures are ethosuximide, valproic acid, and lamotrigine. These medications work by reducing the abnormal electrical activity in the brain. In some cases, surgery may be necessary to treat absence seizures.

What is the prognosis for absence seizures?

The prognosis for absence seizures is generally good. Most children with absence seizures will outgrow the disorder by the time they reach adulthood. However, some people may continue to have seizures throughout their lives. Absence seizures can be effectively managed with medication, and most people with the disorder can live normal, productive lives.

Conclusion

Absence seizures are a common type of childhood seizure. They are typically brief and non-motor, and they do not usually cause any lasting harm. However, absence seizures can be disruptive to a child's education and social life. If you think your child may be having absence seizures, it is important to see a doctor for evaluation and treatment.
