According to Alzheimer’s Disease International, there were an estimated 50 million people with dementia worldwide in 2019, but, by 2050, that number is expected to increase dramatically to 135 million people. In 2018, the United States spent approximately $280 billion to care for people with dementia, which Michael S. Rafii, MD, Ph.D., director of the Memory Disorders Clinic at the University of California, San Diego, says is "greater than the cost of any other disease faced by our society."
