Generally, when death near, the person will be sleeping a lot, they may stop eating and drinking (because their internal organs are shutting down) and they may not be responsive to their caregivers. Frequently, they will be bedridden and incontinent. Often, they may have stopped speaking for some time. However, my father-in-law woke up and told his caregiver a joke just moments before he passed away. Sometimes, right before the end, the person will rally some strength for seeing relatives one last time, and may seem to be getting better. That is why it is really helpful to get help from Hospice services to help you prepare for and understand the end stages of your loved one's life.
As soon as you sense your loved one with Alzheimer's is in an advanced stage, I suggest that you contact hospice services. Hospice services vary from city to city but they are generally free, or covered by insurance. The goal of hospice services is to help individuals and families to prepare for the end of life. Because Alzheimer's affects each person's brain differently, it can be hard to know when your relative is nearing the end but a person who has had a great deal of experience and training can see the signs and will not only help you to be prepared, but, even more importantly, be able to make sure your loved one gets every possible help to make this process peaceful, comfortable and painless. Hospice services generally can call a doctor at any time and get a quick response and access to pain medicine or other things that might be needed. Additionally, they can provide people to relieve relatives to sleep or rest.
