This is not an infectious disease issue, but it is certainly a public health issue that we will all confront sooner or later—probably sooner. As I approach the age of 73, and knowing how quickly my mother slipped into dementia, I take a personal interest. Thanks to Lucie Lecomte for sending the link to this Reuters report: Dementia epidemic looms with 135 million sufferers seen by 2050. Excerpt:
Many governments are woefully unprepared for an epidemic of dementia currently affecting 44 million people worldwide and set to more than treble to 135 million people by 2050, health experts and campaigners said on Thursday.
Fresh estimates from the advocacy group Alzheimer's Disease International (ADI) showed a 17 percent increase in the number of people with the incurable mind-robbing condition compared with 2010, and warned that by 2050 more than 70 percent of dementia sufferers will be living in poorer countries.
"It's a global epidemic and it is only getting worse," said ADI's executive director Marc Wortmann.
"If we look into the future the numbers of elderly people will rise dramatically. It's vital that the World Health Organization makes dementia a priority, so the world is ready to face this condition."
Alzheimer's, the most common form of dementia, is a fatal brain disease that has no cure and few effective treatments.
Like other forms of the disorder, it affects patients' memory, thinking and behavior and is an increasingly overwhelming burden on societies and economies. While there are a few drugs that can ease some symptoms in some people, there is no cure.
Even now, the global cost of dementia care is more than $600 billon, or around 1.0 percent of global gross domestic product (GDP), and that will only increase, the ADI says.
In a policy report published along with the new data, Martin Prince, a professor at King's College London's Institute of Psychiatry, said "most governments are woefully unprepared for the dementia epidemic". His report said only 13 countries have national dementia plans.
