Signs and Symptoms
Some people — roughly 15 percent — with cavernous malformations may not experience any symptoms at all, while others may suffer from a variety of effects. Symptoms typically depend on the location of the malformation and may include:
- Seizures ranging in severity, duration and intensity
- Neurological deficits, such as weakness in arms and legs as well as problems with vision, balance, memory and attention
- Headaches ranging in severity, duration and intensity
- Bleeding, called a hemorrhage, in the brain that may damage surrounding brain tissue
