common causes of death in old people
Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people. Alzheimerâs is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioningâthinking, remembering, and reasoningâand behavioral abilities to such an extent that it interferes with a personâs daily life and activities.
