Physicians' perceptions of suffering in people with dementia at the end of life.

Most patients with dementia did not suffer during their final hours of life, according to their physicians. There are a number of factors associated with suffering, among them death with pneumonia and unexpected death. We may not be able to have much influence on death from pneumonia, but quality of care and an unexpected death are reasonable targets for intervention. Earlier identification of the beginning of the dying process would allow time to better prepare for approaching death, which would provide a source of comfort.
