The symptoms of Alzheimer's disease worsen over time, although the rate at which the disease progresses varies. On average, a person with Alzheimer's lives four to eight years after diagnosis, but can live as long as 20 years, depending on other factors.
How long can someone survive with dementia? The answer in part depends on the gender of the person in question. Women have longer life spans than men in general. Men live for about four years and one month after Alzheimerâs disease develops, while women can live for 4 years and six months.
