Living with Microangiopathy and leukoencephalopathy, pontine, autosomal dominant

A rare inherited small blood vessel disease of the brain with repeated strokes, usually starting in midlife.

Understanding Microangiopathy and leukoencephalopathy, pontine, autosomal dominant

Microangiopathy and leukoencephalopathy, pontine, autosomal dominant is a rare inherited disease of the small blood vessels of the brain.

It causes repeated strokes, often in the part of the brainstem called the pons, typically starting in the 40s or 50s. People have worsening thinking and movement problems. Brain scans show many small strokes and changes in white matter.

Signs & symptoms

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

  • Poor balance
  • Thinking and memory problems
  • Repeated small strokes
  • Worsening movement problems
  • Dementia

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. Consider genetic testing

    Changes in COL4A1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
