Living with Juvenile absence epilepsy

A genetic form of epilepsy that starts around puberty, with brief staring spells and sometimes larger seizures.

Understanding Juvenile absence epilepsy

Juvenile absence epilepsy is a genetic form of epilepsy that starts around puberty.

It causes absence seizures, brief staring spells that happen from time to time. Many people also have generalized tonic-clonic (grand mal) seizures at some point, and some have sudden muscle jerks (myoclonic jerks). It starts in the teen years.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Brief seizures with staring spells (absence seizures)
  • Grand mal seizures (tonic-clonic)
  • Sudden muscle jerks (myoclonus)
  • Seizures affecting the whole brain

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, genetic specialists and seizure and epilepsy specialists.

  3. Consider genetic testing

    Changes in EFHC1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Epilepsy Foundation may keep lists of experts for this condition.
