A new study conducted at Rush University Medical Center in Chicago, IL, USA found that of old adults who died in 2010, 32% suffered Alzheimer's disease.  The rate is expected to be 43% in 2050.  Alzheimer's disease profoundly affects the old adult life.  And the study showed that in 2010, about 600,000 aged 65 or older died with Alzheimer's disease.  In 2050, an estimated 1.6 million Americans are expected to die with Alzheimer's disease.Jennifer Weuveemail, Liesi E.
