Alzheimer’s scourge hangs over ill-prepared Asia

Tags: , , , , , , , , , ,


Asia’s fast-aging population will make up more than half of the world’s dementia patients in 40 years, with China shouldering the biggest chunk.

With very few skilled nursing homes, daycare facilities or plans to build many more, health experts say the region is ill-prepared to cope with the sharp increase 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,” Dr. David Dai, coordinator of the Hong Kong Alzheimer’s Disease Association.

“We are not prepared. The whole of southeast Asia is not prepared,” gerontologist Dai said in an interview.

More than 35 million people suffer from Alzheimer’s disease (AD) and other forms of dementia, a number expected to almost double by 2030 and pass 115 million by 2050, according to Alzheimer’s Disease International (ADI).

Alzheimer’s, the most common form of dementia, robs people of their memory and thought processes and, eventually, bodily functions.

In Asia, 13.7 million people had Alzheimer’s or other forms of dementia in 2005. That is expected 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.

ONE FOR EVERY FAMILY

About 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.

BUT FEW FACILITIES

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,” said Philip Poi, head of Geriatric Medicine at University Malaya.

“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.”

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.

“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.

Cellphones may protect brain from Alzheimer’s

Tags: , , , , , , , ,


A study in mice suggests using cellphones may help prevent some of the brain-wasting effects of Alzheimer’s disease, U.S. researchers said on Wednesday.

After long-term exposure to electromagnetic waves such as those used in cell phones, mice genetically altered to develop Alzheimer’s performed as well on memory and thinking skill tests as healthy mice, the researchers wrote in the Journal of Alzheimer’s Disease.

The results were a major surprise and open the possibility of developing a noninvasive, drug-free treatment for Alzheimer’s, said lead author Gary Arendash of the University of South Florida.

He said he had expected cell phone exposure to increase the effects of dementia.

“Quite to the contrary, those mice were protected if the cell phone exposure was stared in early adulthood. Or if the cellphone exposure was started after they were already memory- impaired, it reversed that impairment,” Arendash said in a telephone interview.

Arendash’s team exposed the mice to electromagnetic waves equivalent to those emitted by a cellphone pressed against a human head for two hours daily over seven to nine months.

At the end of that time, they found cellphone exposure erased a build-up of beta amyloid, a protein that serves as a hallmark of Alzheimer’s disease.

The Alzheimer’s mice showed improvement and had reversal of their brain pathology, he said.

“It (the electromagnetic wave) prevents the aggregation of that bad protein of the brain,” Arendash said. “The findings are intriguing to us because they open up a whole new field in neuroscience, we believe, which is the long-term effects of electromagnetic fields on memory.”

Arendash said his team was modifying the experiment to see if they could produce faster results and begin testing humans.

Despite decades of research, there are few effective treatments and no cure for Alzheimer’s, the most common form of dementia. Many treatments that have shown promise in mice have had little effect on humans.

More than 35 million people globally will suffer from Alzheimer’s disease or other forms of dementia in 2010, according to the Alzheimer’s Association.

There has been recent controversy about whether electromagnetic waves from cellphones cause brain cancer.

Co-author Chuanhai Cao said the mice study is more evidence that long-term cellphone use is not harmful to the brain.

Groups such as the World Health Organization, the American Cancer Society, and the National Institutes of Health, have all concluded that scientific evidence to date does not support any adverse health effects associated with the use of cellphones.

How Low is Your Alzheimer’s IQ? — Research Summary

Tags: , , , , , , , , , ,


BACKGROUND: There are many myths surrounding Alzheimer’s disease, the most common form of dementia. Many think memory loss is a natural part of aging, but according to the Alzheimer’s Association, severe memory loss is now recognized by experts as an indication of a serious illness. Many also don’t realize the disease is fatal. The truth: It will kill you. It robs patients of brain cells, which leads to memory problems, erratic behaviors and the inability of the body to function properly. It also takes away your identity and ability to relate to others.

[ad]

PROTECTING YOURSELF: There is currently no cure for the disease, and in only half of the patients who take the available FDA-approved Alzheimer’s drugs, symptoms slow or stop for six to 12 months. Experts say, however, there are ways to protect yourself. For example, Alzheimer’s disease is directly linked to cardiovascular and metabolic health. Obese people are twice as likely to develop dementia and those with heart disease have a much higher risk of AD. Recent research shows people with high blood pressure, one of the precursors of heart disease, are up to 600 percent more likely to develop dementia. The Alzheimer’s Society of the United Kingdom says treating the condition in midlife can cut the number of deaths from dementia by up to 15,000 people a year. Other studies show having high cholesterol increases someone’s chance of developing dementia by 43 percent and having diabetes increases it by 65 percent.

High glucose levels are also linked to the debilitating disease. A nine-year study of 1,173 diabetes-free people over age 75 showed those with high glucose levels had a 77 percent greater chance of getting AD. Insulin levels decrease with age, making it more difficult for glucose to enter cells, which causes a spike in glucose levels. That results in more waste products like free radicals, in the cells, which can harm blood vessels.

Some experts say Alzheimer’s is a new type of diabetes. In the past few years, researchers at Rhode IslandHospital and Brown Medical School have discovered that insulin and insulin receptors are considerably reduced in the brains of early-stage Alzheimer’s patients. As the disease progresses, insulin levels continue to deplete. They also found that a deficiency in the neurotransmitter acetylcholine, a characteristic of the disease, is associated with insulin loss. They went on to illustrate that potential Alzheimer’s treatments are those that target insulin and its action on the brain. “We have demonstrated that a loss of insulin in the brain triggers the onset of Alzheimer’s, probably because as the brain loses insulin, the cells that require insulin to function and survive also eventually die,” Suzanne M. de la Monte, M.D., senior author of the study, a neuropathologist at Rhode Island Hospital and a professor of pathology at Brown Medical School in Providence, R.I., was quoted as saying. “The consequences are increased oxidative stress, brain deterioration, loss of cognitive function, and a buildup of plaques and tangles in the brain — all hallmarks of Alzheimer’s.”

GIVE YOUR BRAIN A BOOST: GET MOVING! Experts say exercise can protect you from Alzheimer’s disease, but according to the Centers for Disease Control (CDC), only a small number of older adults follow the recommended 30 minutes or more, five days a week guideline. Twenty-eight to 34 percent of adults aged 65 to 74 and 35 to 44 percent of adults over age 75 do not engage in leisure-time physical activity. One reason exercise may prevent AD is by thwarting the buildup of plaque, as shown in mice injected with a gene predisposing them to plaque accumulation. In addition, exercise combats depression. Research by Rush Alzheimer’s Disease Center revealed lonely people are twice as likely to develop AD. According to John J. Ratey, M.D., author of Spark: The Revolutionary New Science of Exercise and the Brain, exercise causes a rush of the neurotransmitter dopamine, which is associated with feelings of pleasure. Dopamine has been shown to slow metabolism in areas of the brain linked to cognition, but with age, dopamine levels taper off.

Alzheimer’s drugs nearly double death risk in elderly: study

Tags: , , , , , , , , , , , , , , , , ,


Anti-psychotic drugs commonly used to treat Alzheimer’s disease may double a patient’s chance of dying within a few years, suggests a new study that adds to concerns already known about such medications.

[ad]

“For the vast majority of Alzheimer’s patients, taking these drugs is probably not a worthwhile risk,” said Clive Ballard of the Wolfson Centre for Age-Related Diseases at King’s College London, the paper’s lead author.

“Would I want to take a drug that slightly reduced my aggression but doubled my risk of dying? I’m not sure I would,” Ballard said.

The research was published Friday in the medical journal Lancet Neurology.

Alzheimer’s disease is the most common cause of dementia and causes symptoms including aggression, delusions and hallucinations.

Previous studies have shown anti-psychotic drugs, which can help control the aggression and hallucinations for a few months, raise the risk of death in older patients with dementia. There are other side-effects, including respiratory problems and stroke.

Ballard and colleagues followed 165 patients aged 67 to 100 years with moderate to severe Alzheimer’s disease from 2001 to 2004 in Britain. Half continued taking their anti-psychotic drugs, which included Risperdal (risperidone), Thorazine (chlorpromazine) and Stelazine (trifluoperazine). The other half got placebos.

Personalize Alzheimer’s treatment

Of the 83 receiving drugs, 39 were dead after a year. Of the 82 taking fake pills, 27 were dead after a year. Most deaths in both groups were due to pneumonia.

After two years, 46 per cent of Alzheimer’s patients taking the anti-psychotics were alive, versus 71 per cent of those not on the drugs. After three years, only 30 per cent of patients on the drugs were alive, versus 59 per cent of those not taking drugs.

In the United Kingdom and the United States, guidelines advise doctors to use anti-psychotic drugs cautiously and temporarily. But in many nursing homes in Europe and North America, up to 60 per cent of patients with dementia are routinely given the drugs for one to two years.

“The drug regimen for any person with Alzheimer’s needs to be personalized,” said William Thies of the Alzheimer’s Association in the U.S. Thies was not connected with the study. “At some points, some people will be better off with no medication.”

Simon Lovestone of the Institute of Psychiatry at King’s College in London said psychiatrists should try environmental or behavioural therapies instead of anti-psychotics.

Experts aren’t sure how the anti-psychotics increase patients’ risk of dying. But they think the drugs could be damaging to the brain and their sedative effects make patients less able to exercise and more susceptible to deadly infections.

Three warnings from Health Canada on the risk of death and stroke among seniors taking antipsychotic drugs failed to reduce the prescription rates of those drugs, according to researchers who suggest health warnings are ineffective at protecting patients.

Between October 2002 and June 2005, Health Canada issued three warnings of increased risk of death or stroke in elderly patients with dementia who take atypical antipsychotic drugs such as risperidone. In a study published in August, researchers concluded that the warnings failed to reduce the prescription rates of those drugs.

The latest study was paid for by the U.K. Alzheimer’s Research Trust. Ballard reported receiving grants from pharmaceutical companies which make drugs used to treat Alzheimer’s patients.

When Alzheimer’s Hits at 40

Tags: , , , , , , , , , , , , , , ,


Brian Kammerer, the 45-year-old chief financial officer of a small hedge fund, called his wife one day from a cellphone in the men’s room of his Manhattan office building. A colleague had just asked him for something, he whispered, but he had no idea what it was.

“It clicks and it holds papers together,” he said.

“A stapler?” Kathy Kammerer asked.

“I think that’s what it’s called,” he replied.

[ad]

Soon after that exchange in early 2003, the father of three was diagnosed with Alzheimer’s disease, capping nearly five years of uncertainty and fear about his increasing forgetfulness and difficulty with language.

While most people who get Alzheimer’s are over 65, Mr. Kammerer is one of about 500,000 Americans living with Alzheimer’s or other dementias at an atypically young age. Alzheimer’s takes a long time to develop — usually, it isn’t diagnosed until 10 years after the first symptoms appear — but more Americans are identifying it early, thanks in part to aggressive screening programs pushed in recent years by groups including the Alzheimer’s Foundation of America, a national alliance of caregivers.

The disease can be especially torturous when it creeps up on those in their 30s and 40s. As these patients move through Alzheimer’s early stages, they are forced to cope with the dread of not knowing what is happening to them, often in the years when they’re raising young children and building financial security. As the disease progresses, there are slip-ups to cover, appearances to keep up. When these “early onset” Alzheimer’s sufferers are finally diagnosed, they face hard questions — whom to tell and when, and what these divulgences mean for their jobs and health insurance.

Overall, an estimated 5.2 million Americans have Alzheimer’s, with as many as 10% diagnosed under the age of 65 — the definition of early onset, according to the Alzheimer’s Association, a national research organization. As the population ages, the number of individuals with Alzheimer’s is expected to hit 7.7 million in 2030.

There are no Alzheimer’s cures now on the market. Current medications mitigate some symptoms but don’t slow or halt the disease’s progression. Pharmaceutical companies are working on new therapies that reduce or remove amyloid, a sticky substance in the brain thought to play a role in the disease. There are more medicines in development for Alzheimer’s than any other neurologic disease except pain, according to Pharmaceutical Research and Manufacturers of America, the industry trade group. It will likely be years before a new generation of drugs makes it to market.

Now 51 years old, Mr. Kammerer, like many Alzheimer’s patients, had no history of the disease in his family. He grew up on the north shore of Long Island, where he stood out at school for his talent with numbers. After attending college at the State University of New York-Albany, he got a job on Wall Street.

Mr. Kammerer met his future wife, Kathy, in 1983 at Donaldson, Lufkin & Jenrette, the investment bank where they both worked. Kathy, who had also grown up on Long Island, recalls not quite believing it when the handsome, fun-loving man with thick brown hair she was dating asked her to marry him.

They wed in 1991. Soon they had a son and two daughters, and Mrs. Kammerer stopped working to care for them at their home in Long Island’s Massapequa Park. Mr. Kammerer commuted into Manhattan.

Mr. Kammerer worked long hours in the office, his wife and former colleagues recall. But he also had a lively and self-deprecating sense of humor. Mrs. Kammerer said he was the life of the party. “He always had a cigar hanging out of his mouth,” she says.

He had “a blue-collar mentality in a white-collar job,” says Martin Jaffe, chief operating officer and co-founder of Silvercrest Asset Management Group LLC, who worked with Mr. Kammerer for 15 years.

Back home, Mr. Kammerer gave his children silly gifts like plastic glasses with fake moustaches and took his wife out dancing on date nights. He whisked the family away on surprise vacations to Florida. In the summers, he loved to barbecue and organized impromptu family slumber parties under the stars, his daughter Kate, now 13, recalls.

In 1998, Mr. Kammerer started complaining of ringing in his ear. He sometimes felt dizzy, Mrs. Kammerer recalls. Other times he gave his wife a look as though he didn’t understand what she had just said. The Kammerers sought out a neurologist, who suggested Mr. Kammerer get a magnetic resonance imaging scan of his brain.

When the MRI results came back, they didn’t look normal, the neurologist told the Kammerers. The doctor was unable to give them a diagnosis, however: He couldn’t say whether there was something wrong, Mrs. Kammerer recalls, or whether Mr. Kammerer’s brain had always looked that way.

Had they even suspected Alzheimer’s, it would have been difficult to diagnose. Doctors look for patients or their families to report a collection of symptoms — such as forgetfulness, social withdrawal and difficulty planning or finishing complex tasks — that worsen over years. (The dizziness and ringing ears Mr. Kammerer experienced aren’t generally considered symptoms.) Currently, Alzheimer’s can be diagnosed conclusively only by autopsy.

Mrs. Kammerer recalls staring at the picture of her husband’s brain. “This is our future,” she thought. She wondered whether she would need to get a job again should her husband be unable to work. The idea of going back to Wall Street terrified her, she says.

The Kammerers agreed that until they knew what was happening, life should go on as usual. They said nothing to the children. Around friends and colleagues, they kept quiet about their concerns, fearing Mr. Kammerer would lose his job if word of his symptoms leaked out. “I lost a lot of sleep,” Mrs. Kammerer says.

One day in 1999, Mrs. Kammerer grew more alarmed: Her husband couldn’t remember the word “sneaker.” Soon after that, he started saying things like “my brain is just not functioning right here,” Mrs. Kammerer recalls.

That year, at age 40, Mr. Kammerer was named a Chief Operating Officer of DLJ Mutual Funds, a Donaldson Lufkin division. His new responsibilities included presentations to the board of a Wall Street firm of 11,300 employees.

Within a year, Mr. Kammerer was struggling more often with words, a symptom of the disease called aphasia. But, always gifted at math, he showed no sign of having trouble with numbers, a key part of his job.

To compensate, he worked into the night, when colleagues weren’t around. He increasingly called his wife from work, reading her memos he had written to make sure they made sense.

Co-workers say they had no idea what he was going through. Debbi Avidon, who worked for Mr. Kammerer from 1993 to 2001 and is now at J.P. Morgan Chase & Co., says she noticed Mr. Kammerer’s longer hours but attributed it to his workaholic tendencies. “He was always very diligent and thorough,” Ms. Avidon says.

Mr. Kammerer also withdrew socially. The cigar-smoking stopped. So did social drinking.

Mr. Jaffe, Mr. Kammerer’s former boss for much of his time at DLJ, says that had he known about Mr. Kammerer’s memory problems, he’s not sure what he’d have done. “I would hope we would take the high road,” he says. He would have been concerned about whether the condition hampered Mr. Kammerer’s command over important numbers, he says, which might have meant a change in job responsibilities. “There probably are many jobs you can do well with that malady,” he says.

In late 2000, Swiss banking giant Credit Suisse Group acquired DLJ. As is often the case in takeovers, Credit Suisse cut some of DLJ’s top executives. Mr. Kammerer lost his job in June 2001. His severance package included two years of salary and a year of health insurance. He took the rest of the summer off and played a lot of golf.

By then, Mrs. Kammerer says, her husband didn’t recognize certain people and couldn’t name some objects. He became good at covering, smiling if he didn’t know what he was being asked or calling people whose names he’d forgotten “sweetie” or “buddy.”

Mr. Kammerer didn’t consider leaving the work force. His kids were all under the age of 12. There were many more years of private-school and college tuition to pay.

But he began to lower his sights. Returning home from a positive interview for a prestigious job — running a European company’s U.S. operations — he told his wife: “You know, Kathy, I don’t think I can do this.”

Instead, he sought out lower-level financial-industry jobs that wouldn’t require him to work closely with others. He wrote out cue cards to take with him on interviews and changed the topic when he didn’t understand what an interviewer had asked.

In 2002, he landed a position as chief financial officer at a small hedge fund, called Clipper Trading Associates, a position that involved managing the fund’s accounting and administration but not making trading decisions.

During this period, Mr. Kammerer visited specialist after specialist, his wife recalls. Suspecting stress was behind his symptoms, he sought out a psychotherapist and was prescribed antidepressants. He took antibiotics for six months to treat what doctors thought might be Lyme disease.

His eldest child, Patrick, noticed that his father seemed particularly absent-minded. One day, Patrick says, he prank-called Mr. Kammerer at his new job and told him he was calling from “Clipper Hedge and Grass Trimming.” Though father and son had often teased each other this way, Mr. Kammerer didn’t recognize his son’s voice or realize it was a joke, Patrick recalls.

One evening in 2003, after yet another test, a type of brain scan called a positron emission tomography, Mr. Kammerer’s physician called. Sitting in their bedroom, Mr. and Mrs. Kammerer got on separate phones to listen in.

“Mrs. Kammerer, I have some terrible news,” she remembers the doctor saying. “I believe your husband has Alzheimer’s.”

Mrs. Kammerer dropped to her knees. She recalls that her husband didn’t understand what was going on and told the doctor, “You have to hold on, something’s wrong with my wife.” They locked the bedroom door so the children couldn’t walk in. After Mrs. Kammerer explained to her husband that he had been diagnosed with a form of dementia, they sat quietly. “Your life kind of flashes before your eyes,” she says.

Mr. Kammerer had private disability insurance, but he relied on his job at Clipper for the family’s health insurance. Another significant concern was the cost of the children’s private school education. Mr. Kammerer decided to work as long as possible.

In 2004, Clipper announced it was shutting down.

The fund closed, it said at the time, because its potential risks in the market were outweighing the rewards it was offering its investors. Two of the fund’s partners, David Dahlberg and Scott Simon, say they were aware that Mr. Kammerer had been having health issues, specifically “inner ear” problems. “It wasn’t something that was affecting his job performance,” said Mr. Dahlberg. He added that had the partners known about Mr. Kammerer’s memory difficulties, he’s not sure how the professional relationship would have changed.

“That’s a difficult position for an employer to be in any business, let alone our business, where short-term memory is important,” said Mr. Dahlberg.

By then, Mrs. Kammerer says, it was clear to her and her husband that he had deteriorated too much to try to find another job.

Mrs. Kammerer went back to work as an office assistant in the District Court in Hempstead, N.Y., providing the family with a small income and health insurance. His wife’s return to work distressed Mr. Kammerer, who saw it as his responsibility to support the family, she recalls.

The Kammerers also filed for Social Security disability benefits. The attorney they hired to help them with the massive paperwork told them the process could take up to 18 months, panicking Mrs. Kammerer. But they caught a break: Their application was approved in five weeks. Mr. Kammerer’s private disability insurance policy, which he took out in the ’90s, added several hundred dollars to their monthly Social Security payout and Mrs. Kammerer’s court salary.

The Kammerers organized one last family trip to Ft. Lauderdale, Fla. They told Patrick about his father’s condition before leaving, but waited until later to tell the younger children, Colleen, now 14, and Kate.

At the end of 2006, the Kammerers transferred their assets to Mrs. Kammerer’s name to shield their estate from the treatment costs Mr. Kammerer is likely to face as the disease makes its slow progress. Mrs. Kammerer says her husband’s care costs $5,000 to $6,000 a year in co-payments on top of what their insurance covers. The costs are likely to escalate: Mr. Kammerer stays home while his wife is working and the kids are at school. In-home care, or a nursing home, would cost more. Mrs. Kammerer says she hopes that day is still years away.

Mrs. Kammerer wrestles with when to take responsibilities away from her husband. He still has his driver’s license, though he doesn’t drive anymore. The plan is to have him sit in the passenger seat and supervise Patrick, now 16, as he learns to drive this year.

Ten years after he first complained of a buzzing in his ears and five years after he was diagnosed, Mr. Kammerer spends most of his days sitting in a club chair in his bedroom and working intricate number puzzles. Two days a week, he attends a program for adults in their 30s through 50s who have dementia, where his favorite activity is dancing.

His math skills remain sharp, but he has trouble recognizing neighbors he has known for two decades. Rather than fiddle with objects he no longer understands, such as the stove, he ignores them. Sometimes, he takes a cab to a nearby golf course without telling anyone and hitches a ride back from a stranger, which unnerves Mrs. Kammerer.

Mrs. Kammerer says the most difficult aspect of her husband’s disease is that the couple used to be a team, but now she has to make the decisions on her own.

“We had a partnership and built a life together, and it was just taken away,” she says.
