New Onset Absence Seizures In Adults


Absence seizures,

or petit mal seizures, are a type of epilepsy. Both sides of the brain are affected. A seizure is an episode of abnormal brain activity. You are not aware that the seizure happened. Absence seizures can happen more than 100 times each day. Absence seizures usually do not cause serious health problems. Some people also develop another type of seizure called a tonic-clonic seizure. This is a seizure that causes convulsions. Absence seizures are most common in children and adolescents. They can also start in adulthood. This is called an adult new-onset seizure.

What are the signs and symptoms of an absence seizure?

  • A sudden stop in talking or doing something for a few seconds
  • Blankly staring ahead without being aware of your surroundings
  • Not responding when spoken to
  • Repeated movements, such as lip-smacking or eyelid fluttering
  • After the seizure ends, suddenly continuing the activity you were doing before the seizure started

Seek care immediately if:

  • You are confused for several minutes after a seizure.
  • You have an absence seizure in water, such as a swimming pool or bath tub.

Contact your healthcare provider if:

  • You are depressed or anxious because of the seizures.
  • Your seizures start to happen more often or last longer.
  • You continue to have absence seizures even with treatment.
  • You have questions or concerns about your condition or care.


Medicines will help control the seizures. You may need medicine daily to prevent seizures. Do not stop taking the medicine unless directed by a healthcare provider.

What you can do to help manage or prevent absence seizures:

  • Take the seizure medicine every day at the same time. This will also help prevent medicine side effects. Set an alarm to help remind you to take the medicine every day. Do not stop this medicine without direction from a healthcare provider. If you are a woman, talk to your provider about family planning while you are taking this medicine.
  • Set a regular sleep schedule. Lack of sleep can trigger an absence seizure. Go to sleep and wake up at the same times every day. Keep your room dark and quiet. Talk to your healthcare provider if you are having trouble sleeping.
  • Keep a seizure diary. Write down the dates of the seizures. Include where you were, and what you were doing. Also include anything that happened during the seizure, such as lip-smacking. Bring the diary with you to follow-up visits with healthcare providers. This may help you and the providers change your treatment.
  • Ask what safety precautions to take. Talk with your healthcare provider about driving. You may not be able to drive until you are seizure-free for a period of time. You may need to check the law where you live. Tell your provider about your workplace. He or she can tell you about any safety risks where you work. An example is operating heavy machinery. Also talk to healthcare providers about swimming and bathing safety. You may drown or develop life-threatening heart or lung damage if a seizure happens in water.
  • Talk to others about the seizures. Tell your family members, friends, and coworkers what to expect with the seizures. Make sure everyone knows not to shake or push you to make you respond. Explain that the episode should only last a few seconds and to be patient.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.
