Complications
The most concerning complications of CCMs stem from recurrent bleeding (hemorrhage), which may lead to progressive neurological damage.
Hemorrhages are more likely to recur in people with prior diagnosed hemorrhages. They're also more likely to reoccur with malformations located in the brainstem.
