What is Alzheimer’s disease?
Who has Alzheimer’s disease?
- Although not all memory loss indicates Alzheimer’s disease, one in ten people over 65 years of age, and over half of those 85+ have Alzheimer’s disease. Currently, 26 million people worldwide have this dementia, and over 15 million Americans will be affected by the year 2050.
- Early-onset Alzheimer’s effects patients under the age of 65. This relatively rare condition is seen more often when parents or grandparents developed Alzheimer’s disease at a young age, and is generally associated with three genetic markers.
