For a patient with cerebrovascular disease who is also being followed by cardiology, how can they communicate in advance what matters most to them in future care?

You can write down the daily abilities you care most about, the types of care you are willing to accept, and who you want involved in discussions, and give this to the medical team at your visit. Ask the doctor to explain, based on your current situation, what options can be discussed, and how these wishes will be documented and later updated. Family members can help express your wishes, but every effort should be made to preserve your own participation and decision-making.
