- AD affects more than 4 million
Americans. - One in 10 people over the age of 65 are affected. - Nearly 50% of all people age 85 and older may have symptoms of AD - If nothing changes, AD is likely to affect up to 14 million Americans by 2050. - An intervention that could delay the onset of AD by 5 years would reduce the number of persons with AD by 50% by the year 2050 (Brookmeyer et al. 1998). - The % of non-Caucasians in the US population is growing rapidly. By 2050 the % of Americans >65 year old will have increased from its current 16% to 34%. - African Americans and Hispanic Americans may have higher overall risk of AD than do Caucasians (Tang et al. 1998). Therefore forecasts for AD in the US may be underestimated. |
