Typical cerebral metabolic patterns- PSP, etc.

These Dutch researchers gave FDG-PET scans to nearly 100 patients — 21 with clinical diagnoses of MSA, 17 with PSP, 10 with CBD, 6 with DLB, and some with PD, AD, and FTD.

“Disease-specific patterns of relatively decreased metabolic activity were found in…MSA (bilateral putamen and cerebellar hemispheres), PSP (prefrontal cortex and caudate nucleus, thalamus, and mesencephalon), CBD (contralateral cortical regions), DLB (occipital and parietotemporal regions)…”

“This implies that an early diagnosis in individual patients can be made by comparing each subject’s metabolic findings with a complete database of specific disease related patterns.”

Abstract
The differential diagnosis of neurodegenerative brain diseases on clinical grounds is difficult, especially at an early disease stage.

Several studies have found specific regional differences of brain metabolism applying [(18)F]-fluoro-deoxyglucose positron emission tomography (FDG-PET), suggesting that this method can assist in early differential diagnosis of neurodegenerative brain diseases.

We have studied patients who had an FDG-PET scan on clinical grounds at an early disease stage and included those with a retrospectively confirmed diagnosis according to strictly defined clinical research criteria.

Ninety-six patients could be included of which 20 patients with Parkinson’s disease (PD), 21 multiple system atrophy (MSA), 17 progressive supranuclear palsy (PSP), 10 corticobasal degeneration (CBD), 6 dementia with Lewy bodies (DLB), 15 Alzheimer’s disease (AD), and 7 frontotemporal dementia (FTD).

FDG PET images of each patient group were analyzed and compared to18 healthy controls using Statistical Parametric Mapping (SPM5).

Disease-specific patterns of relatively decreased metabolic activity were found in PD (contralateral parietooccipital and frontal regions), MSA (bilateral putamen and cerebellar hemispheres), PSP (prefrontal cortex and caudate nucleus, thalamus, and mesencephalon), CBD (contralateral cortical regions), DLB (occipital and parietotemporal regions), AD (parietotemporal regions), and FTD (frontotemporal regions).

The integrated method addressing a spectrum of various neurodegenerative brain diseases provided means to discriminate patient groups also at early disease stages. Clinical follow-up enabled appropriate patient inclusion.

This implies that an early diagnosis in individual patients can be made by comparing each subject’s metabolic findings with a complete database of specific disease related patterns. (c) 2010 Movement Disorder Society.

Economist Magazine Report on Human Genome

The Economist magazine has a great report on the human genome. Admittedly, it’s challenging reading much of the time.

Many of us following the PSP/CBD genetics project will be familiar with the term GWAS – genome-wide association study. The genetics project is a GWAS taking place on brain tissue of confirmed PSP and CBD patients. This magazine report has a lot to say about the strengths and limitations of GWAS. One of the recent “discoveries” we learned about was that someone needs multiple genetic mutations to develop PSP or CBD; apparently this isn’t a finding specific to PSP or CBD.

Two other things I learned from this special report with regard to GWAS are:

“GWAS has not been a total failure. It has revealed lots of mutations of small effect. On average, though, these add up to only 10% of the total heritability of any given disease. Mendelian effects add about another 1%. The rest, in a phrase that geneticists have borrowed from physicists, is referred to as ‘dark matter’. These mutations appear to be tremendously important, yet neither Mendelian nor GWAS techniques can detect them. Mendelian mutations are noticed because they are rare and powerful. GWAS mutations are seen because, though puny, they are common. The dark matter lies in the middle: too rare for GWAS but not powerful enough to leave a clear Mendelian signal. Bigger GWAS, with more statistical power, may help a bit, but clearly new methods are needed. One will be to deploy whole-genome sequencing more widely, now that it is becoming so much cheaper.”

“It is one thing to find a gene in the genome; it is quite another to find out what it does; and another still to understand whether that knowledge has any medical value. Until these points are dealt with, the drugmaking machine that genomics once promised to become cannot be built.”

Gastroparesis, Bowel Dysfunction, and Urinary Problems

The Parkinson’s Disease Foundation (pdf.org) recently published a fact sheet on gastrointestinal and urinary dysfunction in Parkinson’s.  Of course many of those in the Brain Support Network are coping with these same symptoms.

Topics discussed include:  gastroparesis (stomach problems), bowel dysfunction, and bladder and urinary difficulties.

Here’s a link to the fact sheet, written by Dr. Pfeiffer, a neurologist who specializes in non-motor symptoms:

Why brain donation and why Mayo Jax?

Someone emailed me this question today about where a loved one’s brain should be donated:

“Robin – I know you favor the research facility in Florida. How have you reached the conclusion that Mayo Jax is the best?”

Here’s my answer.

There are two key reasons to donate a loved one’s brain — to confirm the diagnosis and to enable research. Brain bank evaluation needs to consider both of these objectives.

With the goal of confirming a diagnosis, these items are important:

* the speed of getting a neuropathology report to families. (Mayo Jax does in 6-8 weeks what it takes 8-16 months for other brain banks to do.)

* the thoroughness of the neuropathology report. (Ask for an idea of how many pages the report will be. Or ask for a sample report for someone diagnosed with the disorder you are interested in. Incredibly, I’ve seen two-sentence neuropath reports!)

* the standing of the neuropathologist, and how many cases he/she has seen of the disorder you are interested in. (I have seen several neuropath reports where the neuropathologist says “this looks like PSP but it also looks like CBD.” In those cases, I’ve suggested that the family order brain tissue be sent to Mayo Jax, and the neuropathologist there comes up with a conclusive diagnosis quite easily. You want someone who has seen lots of cases before such that diagnosis is very straightforward.)

* the financial cost to the family in working with that brain bank. (The disadvantage of Mayo Jax is that the family may pay up to $1500 to accomplish brain donation.)

* the “hassle” to the family in working with that brain bank. This includes how extensive the required paperwork is, the family’s involvement in ordering medical records, and the requirement to find a person to do the brain procurement.

With the goal of utilizing brain tissue for research, these items are important to consider when evaluating a brain bank:

* the quantity of PSP brains they have. If you have a lot of tissue, you can consider brain research. If you have a few dozen brains, it’s probably not enough for a major research article. How do you find this out? Ask the brain bank coordinator how many PSP brains (or whatever the disorder is) they have in their brain bank. Look at the Schellenberg PSP/CBD genetics update to see how many brains were contributed by the various institutions around the world. (See: http://forum.psp.org/viewtopic.php?t=8223)

* the quantity of medical journal articles being published by that brain bank utilizing brain tissue for the disorder of interest. How do you find this out? Ask the brain bank coordinator for a list of all the published journal articles by the neuropathologist on a specific disorder. Or, do a PubMed search (pubmed.gov) with the name of the disorder and the name of the institution (or neuropathologist).

* how long will this brain bank likely be around? Sadly, there is a brain bank located in the LA area that is on the verge of shutting down its freezers, and no longer accepts PD or atypical parkinsonism brain donations! Many major US brain banks are severely cutting back due to the financial situation in the US. (Both UPenn and UCSD no longer accept MSA brain donations though the families/patients were told they could donate brain tissue her upon death. One Southern California woman’s dying wish to donate her brain could not be met by the family because of this problem.)

In the case of PSP/CBD brain donation, Mayo Jax is absolutely the best choice. If you donate a brain here, CurePSP will reimburse part of your brain donation costs. (Lately, the grants have been about $700.)

I mentioned that there are two key reasons to donate a loved one’s brain — to confirm the diagnosis and to enable research. Other reasons our family had or reasons I’ve heard from others include:

* since the diagnostic accuracy of the disorder your loved one was diagnosed with may be less than 55% (this is the case for PSP-parkinsonism, CBD, MSA without early autonomic symptoms, and DLB), the *only* way to in fact discover the diagnosis is upon brain donation. An excellent MD’s best guess is insufficient for most disorders.

* have something hugely positive come out of a bad situation.

* in case something inherited or genetic is ever discovered about PSP or CBD, blood relatives can have certainty in the diagnosis of their loved one.

* many people have said to me that their loved one had a scientific mind and would want to participate in a scientific endeavor.

* many people have said to me that their loved one was a very generous person and would want to make this most generous of donations. Some point to the fact that their loved ones are organ donors.

* one woman said to me that donating her loved one’s brain was the last step in caring for him. She felt that brain donation was a natural extension of caregiving.

* many people report peace of mind in knowing the final diagnosis.

What’s your opinion about these things?

“Spouses Face Hurdles When Caring…”

This news article is about the fact that “caring for a sick or disabled elderly relative exacts a toll — physical, emotional, financial — on any family member, but being a spousal caregiver brings particular challenges.” One of the researchers mentioned in the article is co-author of a recent study of LBD caregivers. He says: “Spouses are likely to take on more than they can reasonably do.” Other key excerpts are:

“In an oft-cited study published in the Journal of the American Medical Association in 1999, University of Pittsburgh researchers followed nearly 400 elderly spousal caregivers for four years and reported that those experiencing mental or emotional strain had 63 percent higher mortality rates than non-caregivers. (Caregivers not experiencing emotional or mental strain did not have elevated mortality rates.)”

“And a study published this year by a team from the University of South Florida and the University of Alabama at Birmingham found that high caregiving strain among spouses increased the risk of strokes by 23 percent; the association was particularly strong among husbands caring for wives.”

Spouses Face Hurdles When Caring For Themselves, Ill Loved Ones

By Paula Span
Kaiser Health News
(produced in collaboration with The Washington Post)
May 25, 2010

They met on a blind date in 1949 and married two years later. They lived in the same Cape Cod-style house in Silver Spring for nearly 50 years. So when Leonard Crierie was diagnosed with Alzheimer’s disease in 2005, there was no question that his wife, Betty, would take care of him at home for as long as she could.

Betty led him into the shower, helped him dress each morning and took him everywhere with her because, once he started wandering, as some dementia patients do, she dared not leave him alone. She learned how to change the colostomy bag he wore since he’d survived rectal cancer years earlier. She slept, fitfully, with a monitor by her bed so that she could respond if he needed her at night.

“It was difficult, but I was able to take care of him,” says Betty, now 80. “Because it happens slowly, you don’t realize how bad it’s getting.”

She agreed to have Leonard attend an adult day program at nearby Holy Cross Hospital — he enjoyed socializing there — so that she could get a few hours’ break several times a week; she found a Holy Cross caregivers support group very useful. But she refused the pleas from her three adult children to hire an aide to help at home. “I always felt like I had it under control,” she explains, though her children thought the $18-an-hour cost also troubled a frugal woman who shops at dollar stores.

As the months passed, “we could see the stress level affecting her,” recalls her daughter Linda Fenlon. “The frustrating part was, we wanted her to have some independence, some quality of life. But she saw it as her duty in life to take care of him.”

For four years, Betty Crierie rarely asked for or accepted her family’s help, until a Wednesday last June. As she left her support group meeting, she remembers, “I got this funny feeling in my chest.” It worsened on the 10-minute drive home. She called her daughter and said, “I’m calling 911. I think I’m having a heart attack.”

‘In Sickness And In Health’

Caring for a sick or disabled elderly relative exacts a toll — physical, emotional, financial — on any family member, but being a spousal caregiver brings particular challenges.

“Spouses are older and dealing with their own age-related health limitations,” says Steven H. Zarit, a Pennsylvania State University gerontologist. The tasks they shoulder have grown more demanding: Family caregivers now administer arsenals of medications and undertake procedures, from wound care to dialysis, that were once the province of medical professionals.

Moreover, today’s longer life spans, in which once-fatal conditions such as heart disease have become manageable chronic illnesses, mean that the “sickness” part of “in sickness and in health” can last for many years. Spouses determined to single-handedly honor their vows, says Suzanne Mintz of the National Family Caregivers Association, “are using their old rules to fight a new problem.”

The medical and psychological literature have long reported that caregivers face risks to their own well-being, especially when they’re caring for people with dementia. Caregivers under stress have higher levels of depression and anxiety; their immune systems suffer. A 2005 Commonwealth Fund overview found that caregivers of all ages reported chronic conditions — including heart disease, diabetes, cancer and arthritis — at nearly twice the rate of non-caregivers, 45 percent vs. 24 percent.

In an oft-cited study published in the Journal of the American Medical Association in 1999, University of Pittsburgh researchers followed nearly 400 elderly spousal caregivers for four years and reported that those experiencing mental or emotional strain had 63 percent higher mortality rates than non-caregivers. (Caregivers not experiencing emotional or mental strain did not have elevated mortality rates.)

And a study published this year by a team from the University of South Florida and the University of Alabama at Birmingham found that high caregiving strain among spouses increased the risk of strokes by 23 percent; the association was particularly strong among husbands caring for wives.

“Spouses are likely to take on more than they can reasonably do,” Zarit says.

Betty Crierie was the classic example: Caring for her increasingly disabled husband, trying to shelter their adult children from the burden, unwilling to bring in a costly home-care aide when she felt she was doing fine on her own — until she had her heart attack. “We didn’t realize how much she was doing until we took turns taking care of Dad ourselves,” Linda Fenlon says. “It was so labor-intensive. We very quickly realized she couldn’t continue.”

While their mother recovered, the children moved their father into a nursing home, a wrenching act for all concerned. Betty visited Leonard there two or three times a week, continuing to do his laundry at home, until he died five months later at age 83.

Depression-Era Values

Why is it so difficult for older caregiving spouses to seek help? Zarit’s research has shown that compared with adult children taking care of an ailing parent, spouses don’t turn to adult day programs until later in the course of illness, and they’re more apt to withdraw the participant after a short time.

Sister Kathy Weber, who leads the Holy Cross support group that Betty Crierie attended, sees a Depression-era-bred reluctance to spend money on care, even when couples can afford it. “They’re supposed to get along somehow and squirrel it away for their kids – who want them to use it now, for their care, which would make the children’s lives easier, too,” Weber says.

Spouses don’t want to lose control of their homes or their relationships. Sometimes they hope to protect their partners’ dignity, not wanting children to see how diminished they’ve become. “There’s a lot of pride there,” Weber says.

What might help, caregiver advocates say, is for health providers to regard older couples as a unit, recognizing that a caregiver’s compromised health could prematurely institutionalize an ailing spouse. Some geriatric practices already do so. “On the intake forms in doctors’ offices, there should be questions to identify whether someone is a family caregiver,” suggests Mintz. “That would alert the physician and the staff to the situation and raise questions about that person’s own health. Is she taking care of herself?”

Meanwhile, President Barack Obama’s proposed 2011 budget would add $102.5 million for family caregiving programs, “a step in the right direction,” Mintz says. The money would boost existing programs that serve family caregivers, including training and counseling, referrals, respite care, transportation, adult day programs and home care. AARP analysts estimate the increased funding could help an additional 200,000 families. Family caregivers can use the help: Medicare pays for doctors and hospitals but provides only very limited post-hospitalization home care, and Medicaid (which covers only the poor) allots most of its dollars to nursing homes. The financial burden of caring for a spouse at home falls mostly to families themselves.

But even with better support, watching a partner decline is difficult. “They are about to lose their lives as they’ve known them,” Weber explains.

That’s what happened to Sheila Fridovich, whose husband, Bernard, developed Pick’s disease, a form of dementia, in his late 60s. Sheila kept him at home in Annapolis, eventually hiring a daytime aide, for nearly six years.

“I couldn’t eat; I couldn’t breathe; I didn’t have a moment’s peace,” she acknowledges. Yet she refused to see a therapist or join a support group. “I needed to iron it out in my own head,” she says.

“We grew up in a generation where getting help from a therapist is not stigmatized,” theorizes her daughter Lauri Fridovich Lee, who joined a support group online. “For the older generation, it is.”

Eventually, consulting with a Veterans Affairs physician about drug coverage, Sheila discovered that Bernard, a Navy veteran, was eligible for admission to a specialized dementia unit at the VA Community Living and Rehabilitation Center in Baltimore. She moved Bernard there in 2006. At 79, he’s still a resident and gets excellent care, she says. But after a stroke, he cannot speak, and she’s not sure, on her Sunday visits, if he knows who she is.

“It’s a traumatic experience for a husband and wife, far more than for their kids,” Fridovich says now. She’s only 71, still working part time as an educational consultant, but “the way I live is not the way I lived before. I’m married but I’m not; I have a husband but I don’t. I’m in no man’s land.”
