Living with Lafora disease

An inherited brain disease that starts in late childhood or the teens with seizures, muscle jerks, and a decline in thinking.

Understanding Lafora disease

Lafora disease (Lafora progressive myoclonus epilepsy) is a brain disorder with repeated seizures and a decline in thinking skills.

Symptoms usually start in late childhood or the teen years and worsen with time. Myoclonus, sudden muscle jerks, can happen at rest and gets worse with movement, excitement, or flashing light. Several seizure types occur, and over time seizures become harder to treat. Early signs include behavior changes, depression, confusion, and speech difficulties.

Signs & symptoms

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

  • Sudden muscle jerks (myoclonus)
  • Seizures
  • Decline in thinking skills (dementia)
  • Balance and walking problems
  • Speech difficulties
  • Depression and confusion

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.

InheritanceAutosomal Recessive

GARD says changes in genes (also called variants) cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
