People with dementia who are no longer competent have limited control over how their lives end. But an advance directive to withhold food and water by mouth could be used to ensure that one does not live for years in severe dementia. Such directives are arguably already legal.
没有能力的痴呆症患者对自己的生命终结方式的控制有限。但是,通过口头拒绝进食和饮水的预先指示可以用来确保一个人不会在严重痴呆症中生活多年。这种指示在法律上可以说是已经存在的。
