Alzheimer's bane clings over ill-prepared Asia

Asia's rapid-aging population will cover more than half of the world's dementia patients in another 40 years, with China holding the biggest chunk. With very less skilled nursing homes, daycare installations or plans to build many more, health experts predict that the region is ill-prepared to deal with the abrupt growth in patients needing such specialized and intensive care.

"Asia will bear the burden because of the aging population in China ... figures in China will be tremendous. We are not prepared. The whole of southeast Asia is not prepared," said Dr. David Dai, coordinator of the Hong Kong Alzheimer's Disease Association, in an interview.
More than 35 million people have been suffering from Alzheimer's disease (AD) and other forms of dementia, a number anticipated to almost double by 2030 and pass 115 million by 2050, according to Alzheimer's Disease International (ADI). Alzheimer's, the most usual form of mental deterioration, robs people of their memory and thought processes and, finally, bodily functions. In Asia, 13.7 million people had Alzheimer's or other grades of dementia in 2005. This has been anticipated to grow to 23.7 million by 2020 and 64.6 million by 2050.
China alone will have 27 million sufferers by 2050 and India 16 million, according to ADI.


Around 10 percent of those in their 70s can expect to have dementia, and 30 percent of those in their 80s.
"Everyone will experience this, every family. It is now common to live to your 80s," said Peter Yuen, director of the Public Policy Research Institute at the Hong Kong Polytechnic University.
In the United States, the annual amount spent by the government, private insurance and individuals to care for people with AD, is projected to jump more than six-fold to $1.08 trillion by 2050, according to the Alzheimer's Association. The costs are just as substantial elsewhere. Yuen, whose mother has Alzheimer's, told a recent AD symposium in Hong Kong that four years of daycare and two years of residential care in a general nursing home in Hong Kong would cost HK$540,000 (US$69,000) per patient. But, even that is an underestimate for 82-year-old Aw Bek-sum, whose children have had to fork out HK$15,000 (US$1,920) each month to take care of her since she was diagnosed with Alzheimer's four years ago. The sum covers daycare, visits to the doctor, a domestic helper and household expenses.
"It's devastating for families with AD patients. There is just not enough support," Yuen said
He proposes long-term financing or some form of pooled insurance for patients who are chronically ill so that services will be made available once the ability to pay is assured. Dedicated facilities for AD patients are scarce in Asia. Hong Kong has 110,000 patients but only 299 places in four daycare centers, and not a single residential care facility. Many end-stage sufferers are put into general nursing homes where staff are not trained to care for them.
"In nursing homes, their conditions get worse because they are normally tied down and they don't have any social interaction, then they die quickly," Dai said. In Malaysia, an estimated 50,000 people suffer from dementia.
"Very few private nursing homes are dedicated to the care of the AD sufferer, although some homes will accept a few AD sufferers if they are not behaviorally challenged, Malaysia is starting to appreciate there is a problem, but currently, care giving is provided mainly by the informal careers such as the spouse or child." 
said Philip Poi, head of Geriatric Medicine at University Malaya.
"Because of China's aging population, the government sees stronger demand for care and medical facilities for the old. It's possible that in the next few years, China will establish more facilities and organizations for old people and dementia patients," said Zhang Shouzi, deputy manager of the Beijing Geriatric Hospital's dementia unit. 
China has up to 8 million dementia patients, but very few hospitals in the country have independent dementia units. By 2030, one in every four Chinese will be over 60.
