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.
While life expectancies are increasing around the globe, one side effect of the aging population is a growing incidence of Alzheimerâs disease. Worldwide, more than 80 million people may suffer from dementia by the year 2040. Knowing how long a person with dementia might survive is important for caregivers and health policymakers. People with Alzheimerâs and other forms of dementia have markedly decreased life expectancies. They are two to four times more likely to die than someone of the same age who does not have dementia.
