Dementia Care: Are Less Drugs and More Tender Loving Care the Answer?


Below the fold, you can read a thought provoking article about the use of drugs versus on hands personal care in nursing homes.

By Bob DeMarco Alzheimer's Reading Room

My recent research, conversations with neurologists, and other specialist indicates that there is a growing consensus that the combination of Aricept and Namenda are getting better results in slowing the progression of Alzheimer's than is commonly known.

I first read about the benefits of the combination Aricept and Namenda in July, 2004  It seems neurologists are finally becoming convinced that this is the way to go.

In the article below, the author "puts the knock" on the use of Aricept and Namenda, but he wrote his article before this new consensus was becoming wide spread. I am in agreement with him about the use of antipsychotic drugs.

I must say, I am completely disconcerted by this finding.
A survey released in 2002 by the Kaiser Foundation found that the staffs in a typical nursing home spend a total of about two hours and 20 minutes a day with each resident. For the remaining 21 hours and 40 minutes, residents are left to their own -- mostly medicated -- devices.
The author asks this simple question, Could the thousands of dollars spent annually per patient and the billions overall be better directed?

When it comes to dementia, forget the drugs

By Ira Rosofsky

Pete Townshend of The Who concluded his baby boomer anthem, "My Generation," with these words: "I hope I die before I get old." And my boomer generation may well still wish for that.

I am 62 -- old enough to cash in my 401(k), too young for Medicare -- and standing with my peers on the edge of a dementia precipice.

Alzheimer's and other forms of dementia afflict up to 5 million people in the United States and about 26 million people worldwide. By 2050, there could be 13 million cases of Alzheimer's alone among U.S. baby boomers and the aging Generations X and Y, according to the National Institutes of Health. Some reports have the global prevalence of Alzheimer's growing to as many as 100 million people by midcentury. The U.S. comptroller general estimates that annual long-term care costs for the elderly -- which includes treatment for dementia -- could quadruple by 2050 to $379 billion.

How should President Obama and his healthcare policymakers, who are working to overhaul our system, prepare for my generation's future? Based on my experience, they can begin by finding a way to end the over-dependence on drugs in treating dementia.

As a psychologist who works in nursing homes, I am intimately aware of the large number of residents who take one or both of two FDA-approved drugs for dementia -- known generically as donepezil and memantine, which together account for more than 90% of the anti-dementia drug market. The most popular brand-name versions, Aricept and Namenda, make up 75% of the market.

I'm also aware of the huge and growing expenditures for these medications -- close to $3 billion annually worldwide for Aricept and more than $500 million for Namenda. Big Pharma spends as many billions of dollars on promotion as it does on research and development.

Examine the documents supporting the Food and Drug Administration's approval of Aricept, and you will see upon what a slim reed this drug's empire was built. Those taking the drug scored, on average, three points better on a 70-item cognitive assessment scale. That's about a 4% difference, mostly reflecting a slower decline rather than positive improvement. And the differences disappear when the drug is discontinued -- indicating that the drugs "do not represent a change in the underlying disease." At best, these effects may be only marginally more effective against dementia than garlic was against the Black Death in the 14th century.

What we do know today, from studies and observation, is that donepezil, memantine and drugs like them fall short on cure and comfort.

Even on Aricept's website, the claims are sketchy on the drug's effectiveness when it comes to cognition: "People who took Aricept did better on thinking tests than those who took a sugar pill."

How much better? The company doesn't say.

Many studies of the effects of drugs for dementia also speak about statistical significance, but statistical significance can be highly overrated if the differences aren't meaningful. Take my extremely nearsighted wife, for example. Suppose a drug enabled her to read the giant E at the top of an eye chart without her glasses, but none of the smaller letters. Her eyesight would show statistically significant enhancement, but -- despite her being a much better driver than me -- I'd still refuse to ride in a car she was driving if she wasn't wearing her glasses.

There are similar effects at play with anti-dementia drugs.

In 2004, Richard Gray of the University of Birmingham in Britain compared hundreds of patients with mild to moderate dementia who were taking Aricept or a placebo. The drug did improve mental functioning, but at disappointingly small levels -- about one point on a 60-point scale. More important, there was no delay in the dementia's progression or the rate of patients' institutionalization. And there were no significant differences in mood, behavior or cost of care.

Based on results such as these, the British National Institute for Clinical Excellence -- the functional equivalent of our FDA -- recommended in 2005 that Britain's National Health Service greatly restrict the use of drugs for dementia. Donepezil can be prescribed only by a psychiatrist or a neurologist, and its use is restricted to cases of mild to moderate -- not severe -- dementia. And memantine is restricted to clinical trials.

Could the thousands of dollars spent annually per patient and the billions overall be better directed?

Yes, says Gray: "Doctors and healthcare funders need to question whether it would be better to invest in more doctors and nurses and better social support rather than spending huge sums of money prescribing these expensive drugs."

A survey released in 2002 by the Kaiser Foundation found that the staffs in a typical nursing home spend a total of about two hours and 20 minutes a day with each resident. For the remaining 21 hours and 40 minutes, residents are left to their own -- mostly medicated -- devices.

Where is the comfort in that?

Some proponents of drug therapy argue that despite some disappointing results, the drugs do slow the worsening of symptoms for some people. But in our medicalized institutions for the frail and elderly, drugs are the first recourse for most problems. And often the second and third recourse.

In the United States, those over 65 consume 30% of the prescription drugs, according to a 2004 report. Dementia sufferers in nursing homes are not only taking donepezil and memantine but other similarly questionable drugs for depression, anxiety, psychosis or for simply being ornery. Many of those without dementia are also on a variety of mind- and mood-altering drugs.

It's easier to medicate than to engage. And when the chemical restraints don't work, nursing homes return to a time before modern psychotropics and use physical restraints.

But why not admit the failure of medication and instead spend some of those billions of dollars on more staff to hold the hands of both patients and their families? Beyond nurturance, much of the savings from giving up on cost-ineffective medications could be diverted to basic research that might yield not only statistically significant but meaningful and large improvements -- even a cure.

There is some comfort in believing, as our medieval ancestors did, that a tangible nostrum -- like a pearl-hued donepezil tablet -- will do some good, but it may be more comforting simply to comfort.

Instead of drugs, I'd bet many patients are wishing someone would just say the words of another ancient rock anthem: I want to hold your hand.
