what is the life expectancy of the elderly with dementia
While life expectancies are increasing around the globe, one side effect of the aging population is a growing incidence of Alzheimerâs 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 Alzheimerâs 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.
