Epilepsy Action and Epilepsy Action Cyrmru has a  care planning document allowing people to record their goals and treatment. https://www.epilepsy.org.uk/professional/primary-care/care-plan-and-review-template

They have released a short statement on advance care planning:

“Healthcare professionals should adopt a shared decision making style that enables the individual with epilepsy, and their family and/or carers as appropriate, to participate as partners in all decisions about their healthcare as a collaborative partnership. Care planning is a process of goal setting and action planning which helps the person with epilepsy to be confident to say what they need and get the support they choose. The epilepsy action care plan includes space for healthcare professionals and patients to collate information about their conditions. We have both English and Welsh versions.”
