Thank you for posting your query.
Cavernous malformations can bleed at times, causing headaches
and other symptoms depending on the location of cavernous malformation and bleed.
Whether or not the malformation has bled, can be found out by doing a CT scan
of the brain.
As of now, these symptoms can also occur due to his high blood pressure
I would suggest to control his BP for now. Symptoms should settle down. If not, then, you can see a doctor and get his CT scan of the brain done.
I hope it helps.
