Living with Progressive myoclonic epilepsy

A group of rare inherited brain conditions with muscle jerks and seizures that worsen over time.

Understanding Progressive myoclonic epilepsy

Progressive myoclonic epilepsy is a rare group of diseases of the brain and spinal cord that cause sudden muscle jerks and seizures.

Symptoms get worse over time. Many of these diseases begin in childhood or the teen years. They are passed from parents to children.

Signs & symptoms

Symptoms vary from person to person. GARD describes these features:

  • Sudden muscle jerks (myoclonus)
  • Repeated seizures (epilepsy)
  • Problems with thinking and memory
  • Abnormal muscle movements or posture (dystonia)
  • Difficulty walking
  • Difficulty speaking

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. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Epilepsy Foundation may keep lists of experts for this condition.
