Costs of Alzheimer's are high today; will skyrocket tomorrow

Alzheimer’s disease is a form of dementia that is becoming more prevalent as the global population ages. Using multiple epidemiological surveys and mathematical models, biostatisticians at the Johns Hopkins University estimated that in 2006 the worldwide prevalence of Alzheimer’s disease was 26.6 million. They predicted that by 2050, prevalence would quadruple and 43% of prevalent cases would need a high level of care equivalent to that of a nursing home.
