Systemic lupus erythematosus
The rate of SLE varies between countries, ethnicity, and sex, and changes over time. In the United States, one estimate of the rate of SLE is 53 per 100,000; other estimates range from 322,000 to over 1 million. In Northern Europe the rate is about 40 per 100,000 people. SLE occurs more frequently and with greater severity among those of non-European descent. That rate has been found to be as high as 159 per 100,000 among those of Afro-Caribbean descent. Childhood-onset systemic lupus erythematosus generally presents between the ages of 3 and 15 and is four times more common in girls.
Alzheimer's Foundation of America
Unless the disease can be effectively treated or prevented, the number of Americans with Alzheimer's disease will increase significantly; projections are that as many as 13.8 million Americans ages 65 and over will be affected by the year 2050.. On January 4, 2011, President Barack Obama signed into law the National Alzheimer's Project Act (NAPA), requiring the Secretary of the U.S. Department of Health and Human Services (HHS) to establish the National Alzheimer's Project to, in part, create and maintain an integrated national plan to overcome Alzheimer's disease; and accelerate the development of treatments that would prevent, halt or reverse the course of Alzheimer's disease. In May 2012, HHS released its historic “National Plan to Address Alzheimer’s Disease.”
