The number of people who have dementia in the U.S. is on the rise, and its the most common mental health problem, with a national average of about 1.5 people per 100,000, according to the American Psychiatric Association.
Many older Americans are getting diagnosed with the condition in their later years, and the rate of diagnosis has grown in recent years.
But there are also signs of a different way to look at the numbers.
In recent years, the number of older Americans diagnosed with dementia has dropped as more and more older adults are taking their own lives, according in the American College of Geriatricians.
But the number in the top 10 countries for dementia in 2015 was up from the number 10 years ago, and in the 10 countries with the highest number of cases last year, it was the highest for the United States, according a study released Monday.
This chart from the World Health Organization shows the number who have a diagnosis of dementia per 100 people in each country in 2015.
