What are the symptoms of brain arteriovenous malformations?

Brain arteriovenous malformations (AVMs) sometimes cause no symptoms and are only found during imaging for other reasons. More commonly, though, AVMs can cause bleeding in the brain, seizures and other neurological problems.

Symptoms can include:

  • seizures
  • persistent headaches
  • weakness or paralysis on one side of the body
  • problems with speaking
  • loss of coordination
  • numbness, tingling or pain

What are the causes of brain arteriovenous malformations?

The cause of AVMs is not known. In most cases, children are born with them. In rare cases, AVMs are associated with conditions that run in families.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
