Living with Bilateral striopallidodentate calcinosis

A condition with calcium deposits in blood vessels of the brain that can cause movement and mood or thinking changes in adulthood.

Understanding Bilateral striopallidodentate calcinosis

Bilateral striopallidodentate calcinosis, also called primary familial brain calcification, is a condition with abnormal calcium deposits in blood vessels of the brain.

Deposits show on medical imaging, mostly in the basal ganglia (deep brain areas that help control movement). Movement and psychiatric or behavior problems usually begin in mid-adulthood and worsen over time. Severity varies, and some people have no symptoms.

Signs & symptoms

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

  • Slow movements (bradykinesia) and stiffness
  • Tremor
  • Uncontrolled limb movements (choreoathetosis)
  • Personality changes, anxiety, or psychosis
  • Memory and thinking decline (dementia)
  • Headache, dizziness (vertigo), or seizures

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 and genetic 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

    Dystonia Medical Research Foundation, Parkinson's Foundation and Parkinson & Movement Disorder Alliance may keep lists of experts for this condition.
