An advance decision is a document in which you can specify any medical treatments which you wish to refuse so that doctors and other medical staff are aware of your decision in case you lack the mental capacity to state your refusal at the time (eg because you have advanced dementia, brain damage or are unconscious). An Advance Decision should clarify the circumstances under which you do not wish to receive specified treatments, as far as possible. It only allows you to refuse certain treatments; not request them. Note that it can be used to refuse treatment even if doing so might lead to your death but it cannot be used to ask for your life to be ended. Unlike an Advance Statement (see below), an Advance Decision is legally binding. An advance statement is a separate document, this sets out how you wish you to be cared for if you are unable to state your preferences due to a lack of mental capacity. It can include a range of matters including dietary requirements and whether you would prefer to be at home or in a medical facility. It may also state any religious beliefs you hold which could affect the treatment you receive. It should be noted that an Advance Statement is not legally binding but doctors and others caring for you must take it into account.
