Several religious traditions are widely believed to advocate the use of life-sustaining treatment in all circumstances. Hence, many believe that these faiths would require the use of a feeding tube in patients with advanced dementia who have lost interest in or the capacity to swallow food. This article explores whether one such tradition--halachic Judaism--in fact demands the use of artificial nutrition and hydration in this setting. Traditional (halachic) arguments have been advanced holding that treatment can be withheld in persons who are dying, in individuals whose condition causes great suffering, or in the event that the treatment would produce suffering. Individuals with advanced dementia can be considered to be dying, often suffer as a result of their dementia, and are likely to suffer from the use of a feeding tube. Given these observations and the absence of a compelling case for distinguishing between tube feeding and other forms of medical treatment, traditional Judaism appears compatible with withholding artificial nutrition for individuals with advanced dementia.
