There are just two ways to die, fast (sudden death) or gradual (old age or disease). Fast death just happens, without warning. Gradual death has a process to it. If it didn’t it would be fast death.

The process of a gradual death from disease takes two to four months (old age with no disease takes longer). Three things are the sign posts that say the dying process has begun: decreased eating, increased sleeping, and withdrawal. These three things are on a continuum, gradually beginning in months before death and going right up to the moment of death.

Weeks before a gradual death there are signs we look for that come in addition to decreased eating, increased sleeping, and withdrawal. On this continuum, in the months before death a person looks frail and sick but does not necessarily look like they are dying. In the weeks before death the person now looks like they are dying. (See Gone From My Sight for a description of all the signs of approaching death).

Dementia doesn’t play by these rules. Someone with dementia does not follow the process of a gradual death; they do not show us the signs that death is approaching. Someone with dementia can withdraw from this world’s activities for years, by being not interested, non-interactive, uncomprehending, unfocused. Someone with dementia can begin sleeping more, or even sleep all the time, and not have entered the dying process. Again, they don’t play by the rules.

Their food intake can decrease but it isn’t until they begin forgetting how to swallow or have difficulty swallowing without choking that dying actually begins. If we don’t eat we can’t live. If the decision not to use a feeding tube is made then the dying process starts. ALWAYS, ALWAYS offer food. You don’t just one day stop feeding someone. Generally, at this point the person is struggling against eating. We are the ones that are concerned. The person’s body has already begun to shut down and is probably disliking food. Offer, but don’t plead. Also beware of choking.

When the decision to not use a feeding tube has been made, depending upon the person’s weight and how much they are eating and drinking, death will probably come within weeks. Now you will see all the signs of approaching death that occur from other diseases and old age. Those signs will fit into the normal timeline that affects others as death approaches.
