One in 10 people over age 65 are likely to develop Alzheimer's disease; for people over age 85 the disease will strike one in two. Molecular biologist John Medina has brought together the information that those affected by the disease most need to know. He provides a detailed overview of the symptoms, explains the underlying biology, includes information about the medications and other treatments used to manage the condition, and offers practical guidance for coping with the hardships of caring for an Alzheimer's patient. Over 150 full colour illustrations help present the complex material in an easy-to-understand format.
