The Meds That Impair Decision-Making

Impairment to cognitive function is often comorbid with Parkinson’s disease. That is to say: it’s not a symptom of Parkinson’s, but it often occurs in the same people. This may seem natural: after all, both are strongly associated with aging.

However, recent (last month, at time of writing) research has brought to light a very specific way in which medication for Parkinson’s may impair the ability to make sound decisions.

Obviously, this is a big deal, because it can affect healthcare decisions, financial decisions, and more—greatly impacting quality of life.

(in which older people were found more likely to be influenced by the impulsive financial preferences of others than their younger counterparts, when other factors are controlled for)

As for how this pans out when it comes to Parkinson’s meds…

Pramipexole (PPX)

This drug can, due to an overlap in molecular shape, mimic dopamine in the brains of people who don’t have enough—such as those with Parkinson’s disease. This (as you might expect) helps alleviate Parkinson’s symptoms.

However, researchers found that mice treated with PPX and given a touch-screen based gambling game picked the high-risk, high reward option much more often. In the hopes of winning strawberry milkshake (the reward), they got themselves subjected to a lot of blindingly-bright flashing lights (the risk, to which untreated mice were much more averse, as this is very stressful for a mouse).

You may be wondering: did the mice have Parkinson’s?

The answer: kind of; they had been subjected to injections with 6-hydroxydopamine, which damages dopamine-producing neurons similarly to Parkinson’s.

This result was somewhat surprising, because one would expect that a mouse whose depleted dopamine was being mimicked by a stand-in (thus, doing much of the job of dopamine) would be less swayed by the allure of gambling (a high-dopamine activity), since gambling is typically most attractive to those who are desperate to find a crumb of dopamine somewhere.

They did find out why this happened, by the way, the PPX hyperactivated the external globus pallidus (also called GPe, and notwithstanding the name, this is located deep inside the brain). Chemically inhibiting this area of the brain reduced the risk-taking activity of the mice.

This has important implications for Parkinson’s patients, because:

  • on an individual level, it means this is a side effect of PPX to be aware of
  • on a research-and-development level, it means drugs need to be developed that specifically target the GPe, to avoid/mitigate this side effect.

Don’t want to get Parkinson’s in the first place?

While nothing is a magic bullet, there are things that can greatly increase or decrease Parkinson’s risk. Here’s a big one, as found recently (last week, at the time of writing):

Air Pollution and Parkinson’s Disease in a Population-Based Study

Also: knowing about its onset sooner rather than later is scary, but beneficial. So, with that in mind…

Recognize The Early Symptoms Of Parkinson’s Disease

Finally, because Parkinson’s disease is theorized to be caused by a dysfunction of alpha-synuclein clearance (much like the dysfunction of beta-amyloid clearance, in the case of Alzheimer’s disease), this means that having a healthy glymphatic system (glial cells doing the same clean-up job as the lymphatic system, but in the brain) is critical:

  • America’s Health System Isn’t Ready for the Surge of Seniors With Disabilities

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The number of older adults with disabilities — difficulty with walking, seeing, hearing, memory, cognition, or performing daily tasks such as bathing or using the bathroom — will soar in the decades ahead, as baby boomers enter their 70s, 80s, and 90s.

    But the health care system isn’t ready to address their needs.

    That became painfully obvious during the covid-19 pandemic, when older adults with disabilities had trouble getting treatments and hundreds of thousands died. Now, the Department of Health and Human Services and the National Institutes of Health are targeting some failures that led to those problems.

    One initiative strengthens access to medical treatments, equipment, and web-based programs for people with disabilities. The other recognizes that people with disabilities, including older adults, are a separate population with special health concerns that need more research and attention.

    Lisa Iezzoni, 69, a professor at Harvard Medical School who has lived with multiple sclerosis since her early 20s and is widely considered the godmother of research on disability, called the developments “an important attempt to make health care more equitable for people with disabilities.”

    “For too long, medical providers have failed to address change in society, changes in technology, and changes in the kind of assistance that people need,” she said.

    Among Iezzoni’s notable findings published in recent years:

    Most doctors are biased. In survey results published in 2021, 82% of physicians admitted they believed people with significant disabilities have a worse quality of life than those without impairments. Only 57% said they welcomed disabled patients.

    “It’s shocking that so many physicians say they don’t want to care for these patients,” said Eric Campbell, a co-author of the study and professor of medicine at the University of Colorado.

    While the findings apply to disabled people of all ages, a larger proportion of older adults live with disabilities than younger age groups. About one-third of people 65 and older — nearly 19 million seniors — have a disability, according to the Institute on Disability at the University of New Hampshire.

    Doctors don’t understand their responsibilities. In 2022, Iezzoni, Campbell, and colleagues reported that 36% of physicians had little to no knowledge of their responsibilities under the 1990 Americans With Disabilities Act, indicating a concerning lack of training. The ADA requires medical practices to provide equal access to people with disabilities and accommodate disability-related needs.

    Among the practical consequences: Few clinics have height-adjustable tables or mechanical lifts that enable people who are frail or use wheelchairs to receive thorough medical examinations. Only a small number have scales to weigh patients in wheelchairs. And most diagnostic imaging equipment can’t be used by people with serious mobility limitations.

    Iezzoni has experienced these issues directly. She relies on a wheelchair and can’t transfer to a fixed-height exam table. She told me she hasn’t been weighed in years.

    Among the medical consequences: People with disabilities receive less preventive care and suffer from poorer health than other people, as well as more coexisting medical conditions. Physicians too often rely on incomplete information in making recommendations. There are more barriers to treatment and patients are less satisfied with the care they do get.

    Egregiously, during the pandemic, when crisis standards of care were developed, people with disabilities and older adults were deemed low priorities. These standards were meant to ration care, when necessary, given shortages of respirators and other potentially lifesaving interventions.

    There’s no starker example of the deleterious confluence of bias against seniors and people with disabilities. Unfortunately, older adults with disabilities routinely encounter these twinned types of discrimination when seeking medical care.

    Such discrimination would be explicitly banned under a rule proposed by HHS in September. For the first time in 50 years, it would update Section 504 of the Rehabilitation Act of 1973, a landmark statute that helped establish civil rights for people with disabilities.

    The new rule sets specific, enforceable standards for accessible equipment, including exam tables, scales, and diagnostic equipment. And it requires that electronic medical records, medical apps, and websites be made usable for people with various impairments and prohibits treatment policies based on stereotypes about people with disabilities, such as covid-era crisis standards of care.

    “This will make a really big difference to disabled people of all ages, especially older adults,” said Alison Barkoff, who heads the HHS Administration for Community Living. She expects the rule to be finalized this year, with provisions related to medical equipment going into effect in 2026. Medical providers will bear extra costs associated with compliance.

    Also in September, NIH designated people with disabilities as a population with health disparities that deserves further attention. This makes a new funding stream available and “should spur data collection that allows us to look with greater precision at the barriers and structural issues that have held people with disabilities back,” said Bonnielin Swenor, director of the Johns Hopkins University Disability Health Research Center.

    One important barrier for older adults: Unlike younger adults with disabilities, many seniors with impairments don’t identify themselves as disabled.

    “Before my mom died in October 2019, she became blind from macular degeneration and deaf from hereditary hearing loss. But she would never say she was disabled,” Iezzoni said.

    Similarly, older adults who can’t walk after a stroke or because of severe osteoarthritis generally think of themselves as having a medical condition, not a disability.

    Meanwhile, seniors haven’t been well integrated into the disability rights movement, which has been led by young and middle-aged adults. They typically don’t join disability-oriented communities that offer support from people with similar experiences. And they don’t ask for accommodations they might be entitled to under the ADA or the 1973 Rehabilitation Act.

    Many seniors don’t even realize they have rights under these laws, Swenor said. “We need to think more inclusively about people with disabilities and ensure that older adults are fully included at this really important moment of change.”

  • Cure – by Dr. Jo Marchant

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The subtitle here, “a journey into the science of mind over body”, prompts an immediate question: is this book actually about science?

    And yes, yes it is. It’s not about “positive energy” or “tapping into your divine essence” or anysuch. It’s about science, and scientific studies.

    The author’s PhD is in genetics and medical microbiology, not metaphysics or something.

    For those of us who read a lot of clinical studies about a lot of things (hi, regular researcher/writer here), we’re very used to placebo being used as a control in medical science.

    “This drug performed no better than placebo” is generally considered a disappointing statement… But what if the placebo was already having a profound effect? Shouldn’t that be worthy of note too?

    Dr. Marchant looks at more than just drugs, though, and also looks into the science (complete with EEGs and such) of hypnosis and virtual reality.

    The writing style here is very accessible without skimping on science. This is to be expected; Dr. Marchant also has an MSc in science communication, and spent a time as senior editor of New Scientist magazine.

    This isn’t a how-to book, but there are some practical takeaways too, specific things we can do to augment (or avoid sabotaging) any medications we take, for example.

    Bottom line: placebo effect (and its evil twin, the nocebo effect) has a profound impact on all of us whether we want it or not, so we might as well learn about how it works and how to leverage it. This book gives a very good, hard science grounding.

  • Women Rowing North – by Dr. Mary Pipher

    Ageism is rife, as is misogyny. And those can be internalized too, and compounded as they intersect.

    Clinical psychologist Dr. Mary Pipher, herself 75, writes for us a guidebook of, as the subtitle goes, “navigating life’s currents and flourishing as we age”.

    The book does assume, by the way, that the reader is…

    • a woman, and
    • getting old (if not already old)

    However, the lessons the book imparts are vital for women of any age, and valuable as a matter of insight and perspective for any reader.

    Dr. Pipher takes us on a tour of aging as a woman, and what parts of it we can make our own, do things our way, and take what joy we can from it.

    Nor is the book given to “toxic positivity” though—it also deals with themes of hardship, frustration, and loss.

    When it comes to those elements, the book is… honest, human, and raw. But also, an exhortation to hope, beauty, and a carpe diem attitude.

    Bottom line: this book is highly recommendable to anyone of any age; life is precious and can be short. And be we blessed with many long years, this book serves as a guide to making each one of them count.

  • Stop Sabotaging Your Weight Loss – by Jennifer Powter, MSc

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This is not a dieting book, and it’s not a motivational pep talk.

    The book starts with the assumption that you do want to lose weight (it also assumes you’re a woman, and probably over 40… that’s just the book’s target market, but the same advice is good even if that’s not you), and that you’ve probably been trying, on and off, for a while. Her position is simple:

    ❝I don’t believe that you have a weight loss problem. I believe that you have a self-sabotage problem❞

    ~ Jennifer Powter, MSc

    As to how this sabotage may be occurring, Powter talks about fears that may be holding you back, including but not limited to:

    • Fear of failure
    • Fear of the unknown
    • Fear of loss
    • Fear of embarrassment
    • Fear of your weight not being the reason your life sucks

    Far from putting the reader down, though, Powter approaches everything with compassion. To this end, her prescription starts with encouraging self-love. Not when you’re down to a certain size, not when you’re conforming perfectly to a certain diet, but now. You don’t have to be perfect to be worthy of love.

    On the topic of perfection: a recurring theme in the book is the danger of perfectionism. In her view, perfectionism is nothing more nor less than the most justifiable way to hold yourself back in life.

    Lastly, she covers mental reframes, with useful questions to ask oneself on a daily basis, to ensure progressing step by step into your best life.

    In short: if you’d like to lose weight and have been trying for a while, maybe on and off, this book could get you out of that cycle and into a much better state of being.

  • Freekeh Tomato Feast

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Fiber-dense freekeh stars in this traditional Palestinian dish, and the whole recipe is very gut-healthy, not to mention delicious and filling, as well as boasting generous amounts of lycopene and other phytonutrients:

    You will need

    • 1 cup dried freekeh (if avoiding gluten, substitute a gluten-free grain, or pseudograin such as buckwheat; if making such a substitution, then also add 1 tbsp nutritional yeast—for the flavor as well as the nutrients)
    • 1 medium onion, thinly sliced
    • 1 2oz can anchovies (if vegan/vegetarian, substitute 1 can kimchi)
    • 1 14oz can cherry tomatoes
    • 1 cup halved cherry tomatoes, fresh
    • ½ cup black olives, pitted
    • 1 5oz jar roasted peppers, chopped
    • ½ bulb garlic, thinly sliced
    • 2 tsp black pepper
    • 1 tsp chili flakes
    • 1 sprig fresh thyme
    • Extra virgin olive oil

    Method

    (we suggest you read everything at least once before doing anything)

    1) Place a heavy-based (cast iron, if you have it) sauté pan over a medium heat. Add some olive oil, then the onion, stirring for about 5 minutes.

    2) Add the anchovies, herbs and spices (including the garlic), and stir well to combine. The anchovies will probably soon melt into the onion; that’s fine.

    3) Add the canned tomatoes (but not the fresh), followed by the freekeh, stirring well again to combine.

    4) Add 2 cups boiling water, and simmer with the lid on for about 40 minutes. Stir occasionally and check the water isn’t getting too low; top it up if it’s getting dry and the freekeh isn’t tender yet.

    5) Add the fresh chopped cherry tomatoes and the chopped peppers from the jar, as well as the olives. Stir for just another 2 minutes, enough to let the latest ingredients warm through.

    6) Serve, adding a garnish if you wish:

    Enjoy!

  • Eyes for Alzheimer’s Diagnosis: New?

    It’s Q&A Time!

    Have something you’d like to ask us, or ask us to look into? Hit reply to any of our emails, or use the feedback widget at the bottom, and a Real Human™ will be glad to read it!

    Q: As I am a retired nurse, I am always interested in new medical technology and new ways of diagnosing. I have recently heard of using the eyes to diagnose Alzheimer’s. When I did some research I didn’t find too much. I am thinking the information may be too new or I wasn’t on the right sites.

    (this is in response to last week’s piece on lutein, eyes, and brain health)

    We’d readily bet that the diagnostic criteria has to do with recording low levels of lutein in the eye (discernible by a visual examination of macular pigment optical density), and relying on the correlation between this and incidence of Alzheimer’s, but we’ve not seen it as a hard diagnostic tool as yet either—we’ll do some digging and let you know what we find! In the meantime, we note that the Journal of Alzheimer’s Disease (which may be of interest to you, if you’re not already subscribed) is onto this:
