Hospice care focuses mainly on pain management and comfort. This is not to extend life. Hospice is reserved for people who have less than six months to live. But it doesn't mean that you'll be dying within this given period. You can be a hospice for several years due to ups and down of your condition. And if you recover, you can withdraw from being hospice anytime.
In order to be eligible for hospice care, guidelines require at least one dementia-related medical complications such as: aspiration pneumonia, sepsis or severe infections, Upper urinary tract infection, bedsores and severe weight loss.
