Living with Primary central nervous system vasculitis

A rare condition in which blood vessels in the brain and spinal cord become inflamed, causing headaches, stroke-like events and thinking problems.

Understanding Primary central nervous system vasculitis

Primary central nervous system vasculitis is a rare condition with inflammation of small and medium blood vessels in the brain and spinal cord.

It causes nervous system symptoms in one area or many areas, with no other cause found, such as infection or another disease. Symptoms are non-specific and can include headache, strokes or mini-strokes with thinking problems, and weakness on one side of the body. It can occur at any time in life.

Signs & symptoms

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

  • Headache
  • Stroke or mini-stroke (TIA)
  • Weakness or paralysis on one side of the body
  • Thinking and memory problems
  • Trouble finding words (aphasia)
  • Nausea and vomiting

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 autoimmune and inflammatory disease specialists, 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

    Vasculitis Foundation may keep lists of experts for this condition.
