Cerebrovascular Malformations (CVM): Signs and Symptoms

What are the signs and symptoms of cerebrovascular malformations (CVMs)?

Arteriovenous malformations (AVMs), cavernomas, and aneurysms can all cause bleeding in the brain.  This bleeding can cause symptoms such as headachesseizures, sleepiness, and neurological problems like weakness and numbness, and difficulty speaking. These problems can also occur even if a CVM causes no bleeding.

Developmental venous abnormalities (DVAs) do not usuallycause symptoms or neurological problems.
