Summary: Nondrug treatments such as aromatherapy, bright light therapy and caregiver support can complement drug treatments and benefit people with dementia and their caregivers.
Almost all the presentations at ICAD were about molecular biology. They dealt with proteins like amyloid and tau, with genes like APOE and SORL1, and with the inner workings of brain cells. Sitting in dark conference rooms watching these presentations, it was easy for me to lose sight of the real-life problems of people with dementia and their caregivers.
The last session I went to brought my focus back to these real-life problems. It's too bad these presentations were given when many conference attendees were already on their way home - "Psychosocial Issues and Neuropsychology" was one of the most interesting sessions at ICAD! Four of the six presentations were specifically about nondrug treatment of dementia, and it's those presentations I'll focus on in the next few posts.
First up was Dr. Alistair Burns, a Professor and Deputy Dean of Clinical Affairs at The University of Manchester in the UK. He is involved in trials of both drug and nondrug treatments for people with dementia and their caregivers. Some of the nondrug treatments he has studied include:
- aromatherapy - an ongoing trial of melissa oil (lemon balm oil) compared with Aricept or placebo for behavioral symptoms of dementia. Results are due out late in 2008.
- bright light therapy - a trial of bright light therapy for sleep disturbance and agitation in people with dementia. Bright light therapy was found to be a powerful and cost-effective alternative to drug treatment.
- psychotherapy - a trial of brief psychotherapy for improvement of cognitive function, emotional symptoms or overall well-being. In this study, six sessions of psychotherapy did not improve any of these measures.
- caregiver intervention - a three country trial of the effect of advice, support and education for caregivers in addition to Alzheimer's medicines for the people with dementia they were caring for. The trial found that this support significantly improved quality of life for the caregivers, over and above any effect of the Alzheimer's medicines given to the people they cared for.
Other studies have shown the positive role caregiver interventions and nondrug treatments can have in the management of dementia, said Dr. Burns. Dr. Linda Teri and colleagues conducted a trial comparing an antipsychotic medication, an antidepressant, behavioral management therapy and a placebo for agitation in people with Alzheimer's. [Dr. Teri presented in this session, and I'll write about her talk next.] All of these treatments, including placebo, were mildly effective. "Pretty much whatever they did," Dr. Burns said, "a third got better."
In another trial he was involved in, Aricept was tested as a treatment for agitation in people with dementia who did not respond to psychosocial interventions (standardized social interaction, music therapy or elimination of the factors triggering agitation). The drug was not found to be more effective than placebo at treating agitation. But the important thing to note about this study was that nondrug approaches were tried first, and worked for many patients.
Cochrane Reviews on these nondrug treatments found little or no evidence that they work, because of an insufficient number of large, well-designed trials. But that should not be confused with a lack of clinical effectiveness, Dr. Burns said. In his opinion, there is some evidence that they all work, good evidence that some work, and some conflicting evidence.
"We need to overcome the negative perceptions about nondrug treatments, and combine nondrug and drug approaches," said Dr. Burns. "It's important to emphasize that the two can work together for the benefit of patients and their carers."

So, who is likely to pay for "large well-designed trials?" Not likely drug businesses. It will take lots of hard work -- and collective action -- to get establishment funders to attend to this.

You know, Mona, this post very lightly touches on something I've strongly believed but have been so reluctant to mention that I've only vaguely addressed it in the millions upon millions of words in my journals: My belief that one of the reasons my mother's dementia is stable and remains so is because I am always here, have been since the beginning, and she knows I'll continue to be no matter how her mentality wobbles (not to mention her other physical conditions), as it surely does. Certainly, there are other factors involved: She has vascular dementia and, as of this May, it was noted by CT scan that her brain remains essentially the same as it was in 2002 when the evidence of the suspicious mini-stroke was discovered; when her mentality wobbles, I immediately look for physical reasons, these are usually discovered and I see to it that they are addressed. But, overall, it's hard for me not to notice that care philosophy seems to have a lot to do with my mother's demential stability. I can only imagine the following, but, it has occurred to me that, for instance, if there had been a variety of ever changing caregivers moving in and out of her life, even if she "remained in her own home", surely her confusion would have increased. It seems to me, as well, that if I left her alone while she was awake and aware for long periods of time the same would have happened. If I had subtly resented her condition and insisted on trying to lead her rather than follow her, I believe her dementia would have increased. If, at some point, I had opined into the future, scared the shit out of myself and decided it would be best to institutionalize her because I didn't think I had it in me to handle her future, I'm sure she would be dead and would probably have died much, much more confused than she is now.
You know, Mona, I hate to even print these things. It sounds like I am condemning scores of other caregivers, and this is not what I mean to do. I realize that non-progressive vascular dementia is different than other progressive dementias. I realize that many progressive dementias progress so quickly it is impossible for a loved one who wants desperately to be the demented person's caregiver to not suddenly find herself in an out of control situation and out of control herself. And, of course, I can only guess at how many millions of people would be living in poverty, they AND their care recipients, if lots of people chose to do caregiving the way I do it. As well, I certainly can't fault people for looking ahead to their own futures after caregiving and realizing that if they do it the way I'm doing it they are in for a future of poverty when they would be most likely unable, for a variety of reasons to reverse this. That's certainly what I'm looking at. I totally get NOT doing it the way I do it. TOTALLY. And yet...my mother, a woman who by normal caregiving and medical standards would have been drooling or dead by now, isn't. Not only this, but she remains aware enough to know, when she goes to bed for the night, that she'll be greeting another day when she awakens, and she wants to do this.
I'm not saying that I'm doing it, caregiving, "better" than most people. What I'm saying is that we, as a society, aren't, at this point, set up to allow the kind of caregiving I'm doing. My society is not even set up to allow or support me and others in this endeavor or to credit me and others so that we can go on in relative comfort when our care recipients die. No wonder only crazy people (like me) do it this way. What I suspect is that what I'm doing works, but the cost to the caregiver and the care recipient, at this time, is so great that either it cannot be done or, if it is, society decides that, if the caregiver's future after-care life is sacrificed, it is the caregiver's fault, not society's, as the caregiver could have chosen to sacrifice some of all of the care recipient's quality of life and saved herself. Damned awful decision to have to make. I'm completely in agreement with all those who refuse to make the choice I did.
And yet...as this post of yours seems to assert, if we COULD all do it this way, without the threat of a miserable future awaiting us after-caregiving, everyone would be psychologically and socially better off. Everyone.
I'm looking forward to Part 2.
Thank you for this post, Mona. I needed to read this. I needed to know that, at least in theory, I'm not the only one.
