Living with Benign adult familial myoclonic epilepsy

An inherited seizure condition with hand tremors and sudden muscle jerks that is slow or non-progressive.

Understanding Benign adult familial myoclonic epilepsy

Benign adult familial myoclonic epilepsy is an inherited seizure condition with hand tremors and sudden muscle jerks (myoclonus).

People may also have occasional seizures that affect the whole brain or one part. The condition does not get worse, or gets worse very slowly. There are no signs of early dementia or of balance and coordination problems (cerebellar ataxia). It can begin at any time in life.

Signs & symptoms

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

  • Hand tremor
  • Sudden muscle jerks (myoclonus)
  • Seizures affecting the whole brain
  • Seizures affecting one half of the 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. Ask which tests can help

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