Whether Alzheimer’s patients will be awake before they die should be analyzed on a case-by-case basis, as follows: 1. They will not be awake: If Alzheimer’s disease is slowly progressing, and the disease is relatively long, the symptoms of Alzheimer’s disease will gradually worsen, and the vast majority of patients will have some consciousness impairment before they die, similar to a vegetative state, not recognizing the people around them, the environment, not even knowing who they are, not being able to eat, and They cannot eat, are incontinent, and finally die from complications such as pneumonia. Therefore, generally speaking, these patients will not be awake until they die, and the impairment of consciousness will gradually worsen. 2. will be awake: If the disease of Alzheimer’s disease is relatively short, if it is complicated by other diseases, such as heart problems, they may die of heart disease or blood clots, they may be awake before they die.
