I would like to know what are the final steps of dementia,when coning close to death, a loved one has it and stop eating,instead of food she eats plastic,can some please explain to what it is

The final stages are like being in a coma, or a persistent vegetative state. You need to take care of your relative and keep anything harmful out of their reach, just like you would childproof your house if you had a toddler. No mouthwash or medicines or cleaning products should be kept unlocked
