Dementia Affects Nearly 47 Million Worldwide: Report

Nearly 47 million people worldwide have dementia, compared with 35 million in 2009, according to a report released Tuesday by Alzheimer’s Disease International.

The group said if there are no major medical advances, the number of people with dementia will likely double every 20 years, the Associated Press reported. There is no known cure for the disease.

About 58 percent of people with dementia live in developing nations and by 2050, nearly half of all those with the disease will live in Asia, according to Alzheimer’s Disease International.

The cost of treating dementia could rise to $1 trillion in three years, experts say. They urged governments to take steps to ensure better treatment for people with dementia, the AP reported.
