For most of human history, what we now call green, or natural, burial was simply considered “burial.” When someone died, the family, community, or other custodians of the dead would dig a shallow hole in the earth and place the shrouded, unembalmed body inside. The process was simple, unintentionally eco-friendly, and meaningful — an integral religious and cultural practice that became marginalized by colonization and modernization.

Today, green burials are an alternative to embalming fluids and concrete vaults, prioritizing decomposition over preservation, which can wreak havoc on the environment. Each year, conventional funerals in the United States require an estimated 20 million board feet of casket wood, 64,500 tons of steel, 1.6 million tons of concrete for burial vaults, and 4 million gallons of embalming fluid, a carcinogen. By eliminating the need for these materials, natural burials are often more eco-friendly and less expensive than conventional ones.

Each year, conventional funerals in the United States require an estimated 20 million board feet of casket wood, 64,500 tons of steel, 1.6 million tons of concrete for burial vaults, and 4 million gallons of embalming fluid, a carcinogen.

Green burials tend to be shallower than most conventional burials, at 3 to 4 feet rather than 5 to 6 feet; the soil closer to the surface is more amenable to decomposition. It can take two to 20 years for the body and bones to fully decompose, depending on factors like soil type and bacterial and moisture content.

Notably, green burials are legal in every state — but not every cemetery allows them. (If a cemetery requires the purchase of a casket and vault, that is their policy rather than the law.)

Green burials can be performed at green cemeteries, legally designated family burial plots, and conservation burial grounds, which are protected via conservation easements that prohibit development of the land and, often, restore the land with native plants and community management.

However, just because green burial is legal throughout the United States doesn’t mean there is a green burial ground established everywhere yet.

Water cremation — also known as aquamation or alkaline hydrolysis — is an alternative to flame, or fire, cremation.

Like flame cremation, water cremation is a process that reduces human remains to bone fragments. But instead of flame, it uses water and an alkali solution of potassium hydroxide that, when heated, dissolves the body, leaving behind bone fragments and a sterile liquid. Alkaline hydrolysis accelerates the natural decomposition process from the decades required of a conventional casket burial to hours.

During the process, the remains are placed in an airtight capsule with alkalized water, and through gentle water flow, all organic material is broken down. When the process is complete, the bone remains are collected, dried, and processed before being returned to the family.

Environmentally speaking, it’s estimated that water cremation can cut energy use by 90 percent and greenhouse-gas emissions by 35 percent. (Flame cremation produces about 1.04 billion pounds of carbon dioxide each year in the United States.) The effluent is returned to wastewater for processing, so the water is not wasted.

Environmentally speaking, it’s estimated that water cremation can cut energy use by 90 percent and greenhouse-gas emissions by 35 percent.

From a financial perspective, water costs about the same or slightly more than flame cremation.

The aquamation process yields about 20 to 30 percent more ashes. These are typically white or tan, while the ashes from flame cremation are grayer in color.

Water cremation is legal in about half the states, and even where it is legal, few facilities offer the service, making access an ongoing issue.

As such, it’s worth noting that alkaline hydrolysis is the greener cremation option, but fire cremation is considered more eco-friendly than conventional burial. Moreover, there are environmentally conscious steps you can take to make fire cremation an even greener option. (Again, “green” exists on a spectrum.)

The Order of the Good Death, a nonprofit dedicated to “building a meaningful, eco-friendly, and equitable end of life,” offers the following tips to green your fire cremation:

• Choose the crematory closest to you that has the newest equipment.
• Buy carbon offsets yourself or find a funeral home that purchases these for every cremation.
• Don’t buy funeral products that insist they are going to make a tree out of the ashes.

Our parents spent years helping us develop from help­less little bundles of need into independent adults — a favor many adult children want to return. We get that chance as our parents reach an age when they need help negotiating life’s challenges.

Yet aiding Mom and Dad when their bodies weaken and, in some cases, when their minds decline is one of the most stressful things we face as adults.

We have to rethink and renegotiate our relationship with those who raised us. We have to find ways to guide them without dominating them. We have to take into account their unique personalities as well as the physical, emotional, and cognitive changes they experience as they age.

Meanwhile, worries loom in the background: Will there be enough money and support? Will I make mistakes that damage my relationship with my parents permanently? Will arguments with siblings about our parents’ care damage those relationships?

Social worker and attorney Jane Wolf Frances, MSW, JD, author of Parenting Our Parents and the founder of the Parenting Our Parents online support community, offers some recommendations for making the profound transition to paren­tal caregiver. By prioritizing practicalities, allowing space for all emotions, and practicing self-care, she believes adult children can support their aging parents in a way that fosters an even deeper relationship.

Stress Sources

You feel overwhelmed by the pressure, sense of responsibility, and emotions that surface as you watch your parents age. These daunting weights can leave you feeling helpless.

You feel resentful of your parents. All of us have sore points about our upbringing, Frances notes, and some of us carry long-lasting resentments or enduring conflicts with our parents that complicate the prospect of caring for them.

A parent expects more help than you can provide.“Your parent has called you a third time at 3 a.m. wanting you to come over right now, and none of those times was an emergency,” says Frances. Is it OK, or selfish, for you to say, “Mom, I’m not coming over”?

Your parents resist help. “They may be proud of their independence and not recognize how needy they are,” she notes. “So they may balk at your taking the necessary steps for their care.”

Your approach to caring for your parent conflicts with the approach that a care team, siblings, or other family members want to take. “What I’ve discovered from years of leading groups for people whose parents have Alzheimer’s is that dealing with family members, especially siblings, is one of the biggest stressors,” says Frances.

Disagreements can stem from different perceptions of the parents’ situation, she points out. “Those who live close to the parents tend to be pretty realistic about what’s going on and the need for solutions; the siblings who are farther away are often in denial.”

You feel that if you don’t “do it right,” you and your parents will suffer. The parent–child relationship brings up feelings of obligation and guilt, and — especially if you have a tendency toward perfectionism — it’s easy to feel that you’re obliged to handle this important time in their lives without a slip-up.

Success Strategies

1) Do your best to settle past or current relationship issues with your parents.

Working through old grudges or resolving enduring conflicts — potentially using a counselor or neutral third party — can clear the air and prepare all parties to handle future obstacles that could arise during this new phase of your relationship.

When resolving conflict isn’t possible, “at least find a way to make some peace with the things that troubled you earlier on or that you are not peaceful with,” says Frances.

Seeking therapy or joining a support group can be helpful. “If you absolutely can’t resolve these conflicts, and you [or your parents] still harbor resentments, it might be best for you not to take on parenting your parents.”

2) Plan ahead.

As an attorney, Frances was a careful planner when she argued cases; she recommends the same ­approach for supporting a parent. “I think of planning as the exact opposite of worrying,” she says.

The planning should start early — ­ideally, as soon as you or your parents ­notice they need help. It can take multiple forms, including apportioning responsibility among siblings or other family members, checking into and dealing with finances, and learning about what resources are available to your parents.

3) Ask questions.

An important aspect of care planning is a willingness to ask your parents questions that help you understand their situation and wishes for their future, says Frances. “Ask things like, ‘Dad, I understand that you’re thinking about retiring. When do you think you will? Will you and Mom move? How are you going to afford retirement? Is the house paid off? Do you need any help figuring these things out?’”

Making sure you’re on the same page also helps your parents know that you want them to have the future they envision for themselves.

4) Share responsibilities.

“I’m a fan of sharing the responsibilities for caring for parents,” Frances notes. “Share them with your own children or grandchildren, if they’re old enough, and with neighbors and friends of your parents, so the onus doesn’t fall on you alone.”

5) Widen the net of your support system.

You’re likely to know people with skills you don’t possess, and Frances strongly recommends bringing them into the care picture. “If you have a cousin who’s really skillful at accounting, maybe they could help your parents out with the banking,” she says.

If you don’t live near your parents, recruit someone who does and can be a supportive physical presence. “They could take them to the doctor, bringing a phone with so that you, who are at a distance, can ask the doctor questions.”

Frances also encourages communicating with the social workers who do discharge planning after a parent’s hospital stay. “They can be knowledgeable and helpful about resources in the community that you can draw on.”

6) Realize that being present can be enough.

As an antidote to worrying about doing the right thing every time for your parents, Frances reminds us that no one does either parenting or parent-parenting perfectly. You may not be able to answer every call or attend every appointment, but your presence — in whatever form that takes — is more important than you realize.

“So many people feel like they’re not doing enough,” she says. “But caring for a parent isn’t always about doing.” Most of the time, showing up for them as you are able to do so is the best support you can give.

7) Don’t try to manage your parents’ emotions.

Aging and facing mortality generate powerful emotions, she notes. It’s best to allow your parents to feel ­everything that comes up for them. Offer a listening ear when and if you are able, or help connect them with those who can.

8) Seek support for managing your own emotions and boundaries.

Similarly, it’s essential to allow yourself to feel the fears, anxieties, and other troublesome emotions that come with caring for your parents. But these feelings can be overwhelming, Frances says.

“I strongly recommend that people try to find support groups and therapists who are equipped to deal with the emotions in this process.” Professionals can also help you establish and maintain boundaries with needy or demanding parents, so that drawing a line with them doesn’t trigger guilt or shame.

9) Care for yourself.

Self-care takes forms beyond seeking professional help, she explains. It can entail remembering to do things you enjoy and decompressing with physical activities. It is also useful to remind yourself to be grateful for what you have.

10) Share joy.

As stressful as parent-parenting can be, it’s also a time that can bring real intimacy between adult children and their parents, reminding both parties of their importance to each other. Reminiscing, conveying your ­appreciation for who your parents are and what they do, and expressing your love for them can go a long way toward making these years better for everyone.

One of my most poignant final memories of my grandma before she passed away was sitting in her living room with her and other family members and taking turns tossing a ball into a wastebasket. Surrounded by her children, grandchildren, and great-grandchildren, her eyes lit up as she sank her armchair shot from 10 feet away. At 97 years old, the once-talented tennis player was able to give her youngest family members a glimpse of her youth and athleticism.

In our fast-paced world where generations may struggle to find common ground, movement is universal. “When it comes to movement for mixed abilities, remember that there are many ways to move a body,” notes Bowman. (1) “Gardening, (2) playground time, (3) playful dancing, (4) doing art, or (5) cooking and baking are a few examples of move­ments where everyone can go at their own pace and ability.”

Sports and games that accommodate a wide range of ages include (6) bowling, (7) beanbags/cornhole, (8) mini golf, (9) disc golf, and (10) pickleball, which has exploded over the past few years. “Pickleball is a great equalizer — a 10-year-old can play with an 80-year-old,” says Rivera.

Everyone wins when mixed generations move together. “Youth can learn new physical skills from older members, while the older generation can stay updated with new trends and technologies through the younger ones,” says Sabrena Jo, PhD, director of science and research at the American Council on Exercise. “Intergenerational activities help to break down stereotypes about age, promoting understanding and respect across generations.”

Vicky Stanich is all suited up, her fists poised in Barbie-pink TITLE boxing gloves; she’s ready to throw a punch at Parkinson’s disease. Stanich is in a St. Paul, Minn., gym among hanging punching bags, squat racks stocked with free weights, two boxing rings, and posters of champion fighters. When the coach gives the go, she lets loose with a left jab, then a right cross, followed by a feint and a bit of fancy footwork before a further one-two of punches. The jaunty taunt of a fellow boxer — Muhammad Ali, who also fought Parkinson’s — comes to mind: “Float like a butterfly, sting like a bee.”

Stanich, 65, is part of a Rock Steady Boxing class, along with 20 other boxers on this day. Each one has Parkinson’s and each one is fighting back against the disease.

Rock Steady Boxing is one of several progressive functional therapies for Parkinson’s disease (PD). Such therapies are based on movement as varied as tai chi, tango dancing, and cycling. A growing body of research shows that exercise is one of the best — and simplest — antidotes for this disease that has no cure.

Movement aids mobility, agility, balance, and strength — motor functions affected by PD. This then boosts nonmotor functions like neuroplasticity, cognition, and mood. And the boxers have to remember sequences of punches and footsteps, which aids memory and eye–hand coordination.

In addition, programs like Rock Steady offer socialization and camaraderie, which can suffer when someone has a neurodegenerative disease. Plus, participants have to get up in the morning, round up boxing togs, and get to class — no small matter for some people with PD. These exercise-therapy classes are like support groups without the chairs.

“I get up in the morning and I’m stiff and hunched over. Then I box and I feel wonderful. I’m a lot more flexible and clear in my mind. Boxing got rid of my tripping when I walked. I have way more energy, and it helps me the rest of the day.”

“I never dreamed I’d be a boxer,” Stanich says, but after she was diagnosed in December 2018, she discovered the Rock Steady Boxing classes. She has been throwing punches now for four and a half years.

“I get up in the morning and I’m stiff and hunched over,” she says. “Then I box and I feel wonderful. I’m a lot more flexible and clear in my mind. Boxing got rid of my tripping when I walked. I have way more energy, and it helps me the rest of the day.”

After a moment to hydrate and catch her breath, Stanich is ready to go another round.

Understanding Parkinson’s

Like an earthquake, Parkinson’s often begins with a tiny tremor.

“I used to be an expressive, high-energy person,” recalls John Clayton. “But about seven years ago I found myself tired, exhausted, and trembling.”

His doctor remarked that his face seemed frozen into a mask and wondered aloud whether he might have Parkinson’s disease. Clayton went to a neurologist for the first of a seemingly never-ending battery of tests.

He was also starting to stumble as he walked. He began to have a difficult time swallowing, which led to drooling. He felt mired in sluggishness. He woke from sleep unrested and still weary.

Worse yet, he suddenly found himself without will — apathetic, lethargic, his only desire a lack of desire, as he describes it. “Sometimes I sit at my desk just looking into space while torpor and self-pity fill me.”

Clayton, now in his late 80s, notes on the first page of his memoir, Parkinson’s Blues, that PD settled on him like “a vulture.”

A novelist and professor emeritus of modern literature and fiction writing at the University of Massachusetts Amherst, he began documenting his experience with PD following his diagnosis. In part, it was to explain to himself and the world what he was going through. It was also to inform us all about living with the disease.

“I’m in a place I’ve never heard anyone describe: both alive and not alive. Like a ghost, I can look from a distance upon my children, my wife, our friends — and love those I look upon. . . . But secretly, inwardly, I’ll be separate, taking in the world without acting in it.”

But his writing had another motive as well. “The most painful part of having PD is what it does to my thinking,” Clayton explains. “Say I’m taking part in a discussion and I have an idea. The idea is clear enough when I start to speak, but at once the idea is gone. I try to get it together, but I can’t. I ask the other discussants to wait and I struggle to find the idea. But I can’t bring it back.”

Writing, too, is tough. But it’s also empowering and liberating — a way to step back into a semblance of his old self. “Paradoxically, writing about disorientation helps orient me,” he notes.

“I’m in a place I’ve never heard anyone describe: both alive and not alive. Like a ghost, I can look from a distance upon my children, my wife, our friends — and love those I look upon. . . . But secretly, inwardly, I’ll be separate, taking in the world without acting in it.”

The Parkinson’s Pandemic

Chances are, you know someone with Parkinson’s. Some 1.2 million Americans are living with the disease as of this writing in March 2024; the counter at www.pdclock.org/counter/ updates approximately every seven minutes — the same rate at which a new person is diagnosed with PD in the United States. Ten million people worldwide have PD, according to the Parkinson’s Foundation.

There are a range of what are called “parkinsonian” or “parkinsonism” syndromes that can be caused by a stroke, brain injury, medication use, or infections, resulting in tremors and movement issues. Parkinson’s disease is one of these — and it is the most common cause of parkinsonism. In fact, PD is the second-most common neurodegenerative disease after Alzheimer’s. And no two people with PD exhibit the exact same symptoms, age of onset, rate of progression, or treatment response.

The prevalence of Parkinson’s is “rising exponentially,” says Ray Dorsey, MD, the David M. Levy Professor of Neurology at the University of Rochester and coauthor of Ending Parkinson’s Disease. “Parkinson’s disease is the world’s fastest growing neurological disorder.”

“Parkinson’s disease is the world’s fastest growing neurological disorder.”

This has spurred physicians and scientists to label it a pandemic.

“From 1990 to 2015, the number of people with Parkinson’s disease doubled,” Dorsey and his co-authors noted in a 2018 report in the Journal of Parkinson’s Disease. “Just due to aging, this number is projected to double again by 2040.”

“Today, more than 200 Americans were diagnosed with the disease and another 100 died from it,” Dorsey says.

And a growing aging population means that more people will experience Parkinson’s, he notes.

And sadly, he adds, it’s a largely preventable pandemic.

A Pandemic of Our Own Making

Parkinson’s is a “human-made pandemic,” Dorsey explains. Genetics, family history, and head injuries are among the myriad factors that cause PD. Yet only about 15 percent of all people with the disease have an identifiable genetic risk factor, he says.

The main culprits in Parkinson’s are human-created industrial chemicals, pesticides, herbicides, and solvents that are attacking us via air and water pollution and other chemical contact.

“The evidence for this connection is overwhelming,” Dorsey and his coauthors write. “Countries that have experienced the least industrialization have the lowest rates of the disease, while those that are undergoing the most rapid transformation, such as China, have the highest rates of increase.

“All of the evidence indicates that the full effect of the Parkinson’s pandemic is not inevitable but, to a large extent, preventable.”

“All of the evidence indicates that the full effect of the Parkinson’s pandemic is not inevitable but, to a large extent, preventable.”

The disease was first discerned and described as “the shaking palsy” in 1817 by future disease namesake Dr. James Parkinson in Great Britain at a time when industrialization was beginning to boom. But it wasn’t until recent years that scientists made the connection to industrial pollutants.

Our understanding of Parkinson’s as a disease largely of our own making comes thanks substantially to the trailblazing research of Caroline Tanner, MD, PhD, currently the vice chair for clinical research and a professor of neurology at the Weill Institute for Neurosciences at the University of California, San Francisco.

The first clue was uncovered in 1982. J. William Langston, MD, was then the chair of neurology at California’s Santa Clara Valley Medical Center, an affiliate of Stanford, and he was investigating a garage-brewed version of the opiate Demerol that caused parkinsonian symptoms in users. Langston zeroed in on the chemical MPTP, an accidental byproduct of the synthetic heroin, which was found to kill dopamine-producing nerve cells in the brain.

“Dr. Langston and others realized that this drug caused selective injury to the area of the brain that is also damaged in Parkinson’s disease,” Tanner told Neurology Today. “They figured out that it blocked mitochondrial respiration and caused oxidative stress, and when it was observed that MPTP was structurally very similar to pesticides like paraquat and rotenone, that led to the idea that agents like these might be potentially contributing to Parkinson’s.” (Learn more about the importance mitochondria and how to keep these power houses health at “The Care and Feeding of Your Mitochondria.”)

Tipped off by this connection, Tanner began in the mid-1980s to study the effects of pesticides, herbicides, solvents, and other chemicals. In the 40 years since, she has been prolific and tireless in leading the understanding of the environmental factors now linked to Parkinson’s.

Chemicals linked to Parkinson’s include:

• Paraquat and other pesticides and herbicides: Also known by the brand name Gramoxone, paraquat is banned in 32 countries but is one of the most widely used weed killers in the United States.Its use tripled between 2008 and 2018.
• Chlorpyrifos: The most widely used insecticide in the country, it’s sprayed on everything from golf courses to utility poles as well as crops, including almonds, cotton, apples, and other fruits. Other problematic pesticides include rotenone and 2,4-D.
• Trichloroethylene: An industrial solvent also used in dry cleaning, TCE is found in between 4.5 and 18 percent of the U.S. drinking-water-supply sources that are tested on an annual basis, according to the Centers for Disease Control and Prevention (levels are typically below 30 parts per billion). It’s also a carcinogen.
• Other industrial chemicals and metals: Polychlorinated biphenyls (PCBs) were used as coolants and insulators in electrical equipment. Although they’ve been banned for several decades, PCBs continue to exist in the environment because of their long half-life.

Welding work has been associated with a greater risk of PD, possibly due to manganese in fumes; exposure to other metals, such as iron and lead, is also believed to increase the risk of PD. And the exhaust fumes from road traffic has also been associated with an increased risk of the disease.

Parkinson’s Medications and Treatments

“Although Parkinson’s is a progressive disorder, most people can still live long and productive lives,” says Dorsey. While Alzheimer’s sufferers lack medications that make a meaningful difference, Parkinson’s patients are fortunate to have a drug available that helps many people, called levodopa. Below is a survey of current — and some possible future — medications and treatments.

Medications
There is a range of medications to help with Parkinson’s motor symptoms, the most commonly prescribed being levodopa. The drug is absorbed through the intestine and the brain converts it to dopamine. The U.S. Food and Drug Administration (FDA) approved levodopa as a treatment for PD in 1970. And there are other medications, such as carbidopa, that can help support levodopa and alleviate its side effects.

For nonmotor symptoms, a range of medications, supplements, diet, and lifestyle choices can help. The Michael J. Fox Foundation offers a helpful guide at www.michaeljfox.org/medications-treatments. Talk to your healthcare provider for more personalized advice. (For more on natural supplements to boost your mental health, see “8 Key Supplements to Boost Your Mental Health — Naturally.”)

Deep Brain Stimulation
John Foley of Minneapolis was 65 when he was diagnosed with Parkinson’s, although his doctors believe he may have had it for some four years by that time. Soon after his diagnosis, Foley consulted with neurosurgeon Kendall Lee, MD, PhD, at the Mayo Clinic, and opted for deep brain stimulation surgery. DBS involves making small holes in the skull to embed electrodes into the brain. The procedure also includes implanting a pacemaker-like pulse generator under the skin in the chest that is later programmed to send continuous electrical signals to the brain.

In 2019, Johns Hopkins Medicine researchers found that “deep brain stimulation using electrical impulses jump-starts the nerve cells that produce the chemical messenger dopamine to reduce tremors and muscle rigidity that are the hallmark of Parkinson’s disease,” according to a study press release.

DBS is a complex and “potentially risky procedure,” the Mayo Clinic warns on its website. And it’s not right for all PD patients. Still, it may make a difference for some: “Deep brain stimulation won’t cure your condition, but it may help lessen your symptoms.”

For Foley, DBS has been life-changing. “I just returned from my baseline checkup, and I’m better today than I was two years ago,” he says. He has stopped taking PD medications and he holds his hands out to show that they no longer tremble.

After his PD diagnosis, Foley began doing something he’d never considered before: He started writing poetry. “I began writing poetry as a catharsis for dealing with the disease and treatments,” he explains in the introduction to his collection, No Turning Back, which includes artwork by Mary GrandPré, who illustrated the U.S. editions of the best-selling Harry Potter books.

The book is also his testament to the efficacy of DBS. As he writes in his poem “Aftermath”: “Behind the tremors, behind the verdict, it’s still me. / I’m not lost, just working on a new map.”

Focused Ultrasound
In 2018, the FDA approved MRI-guided focused ultrasound (MRgFUS, or sometimes simply FUS) as a noninvasive treatment that helps some Parkinson’s patients manage tremors. Ultrasound is guided by an MRI to the specific areas in the brain. The high-temperature ultrasound waves destroy brain cells that cause movement problems.

FUS is currently approved for use on only one side of a patient’s brain, so it helps with symptoms on only one side of the body. When done on both sides of the brain, FUS may cause speech, swallowing, or memory issues. Researchers are looking to perfect FUS for both sides of the brain.

Vaccination
Vaccines empower antibodies in the body’s immune system to fight off harmful agents, such as the viruses that cause polio or chicken pox. Vaccines can also be aimed at proteins, which may be the key to developing a PD vaccine: “This is convenient in the case of Parkinson’s because misfolded forms of the alpha-synuclein protein — that major factor in the disease — could be targeted,” explains Dorsey and his coauthors in Ending Parkinson’s Disease.

Vaccine studies began in 2017 and continue today.

Parkinson’s Therapies

In recent years, progressive new therapies are helping those with Parkinson’s like never before. Subramanian calls the new understanding of the benefits of exercise, diet, and social connection “game-changers.” Below is a survey of current therapies.

Exercise and Movement
“The power of exercise for people with Parkinson’s disease is remarkable and represents one of the biggest advances over the past 20 years or so,” says movement scientist Gammon Earhart, PT, PhD, associate dean and director of the Program in Physical Therapy at Washington University School of Medicine in St. Louis. “To date, exercise remains the only approach that may modify disease progression.”

Volumes of studies and trials have validated the benefits of exercise as therapy for PD. And while most research focuses on a specific type of movement, in the end it appears that simply moving is the key.

“Exercise has positive effects on movement, mood, thinking, and quality of life, just to name a few.  And it is never too early, or too late, to start exercising.”

“Exercise has positive effects on movement, mood, thinking, and quality of life, just to name a few,” Earhart explains. “And it is never too early, or too late, to start exercising.”

Earhart led trials on tango dancing as Parkinson’s therapy. “Tango has lots of features that enable people with PD to practice things, within the context of the dance, that are often challenging for them. For example, starting and stopping, moving at different speeds, walking backward, turning, and multitasking,” she says. “It is also a social activity that allows the person with PD and their partner or friend to participate on equal footing, which helps with engagement as well as motivation and desire to continue.”

PD therapy classes featuring tango and myriad other styles of dance — Zumba, ballet, and more, both in person and virtual, and in several languages — are offered around the country.

A recent long-term study in China on the effects of tai chi as PD therapy found numerous benefits. “Tai Chi training reduced the annual changes in the deterioration of the Unified Parkinson’s Disease Rating Scale and delayed the need for increasing antiparkinsonian therapies,” the authors note. “The annual increase in the levodopa equivalent daily dosage was significantly lower in the Tai Chi group [compared with a control group].”

Davis Phinney is a former professional bicycle racer who won an Olympic bronze medal as well as two Tour de France stage wins. In 2000 at age 40, he was diagnosed with early-onset PD. He cofounded the Davis Phinney Foundation for Parkinson’s with his wife, Connie Carpenter Phinney. One of its key programs is Pedaling for Parkinson’s, with in-person classes using stationary bicycles at YMCAs, community centers, and gyms across the country. The program also offers virtual classes.

“Participants who ride three days a week over eight weeks have shown improvement in their Parkinson’s-related symptoms by as much as 35 percent,” the group’s website states. “Exercise not only improves your general health, but it also has specific physical, mental, and emotional benefits as you live well with Parkinson’s.” (See “The Health Benefits of Cycling” for more about boosting your overall health with a bike ride.)

“The data that physical exercise is beneficial for people with PD is overwhelming,” says Simon, the Harvard Medical School neurology professor. “Some studies suggest more intense physical activity yields the most benefit, but other studies suggest substantial benefits from moderate-intensity exercise. The exact optimal amount is unclear, but generally we recommend aiming for at least 150 minutes per week of at least moderate-intensity exercise. However, even less than this recommended amount likely still has benefits.”

Exercise may even help prevent PD in the first place.

Exercise may even help prevent PD in the first place. Following the publication of a paper in Clinics in Geriatric Medicine on the status of Parkinson’s research, coauthor Tanner, of the Weill Institute for Neurosciences, predicted in the Washington Post that the 90,000 new Parkinson’s cases currently diagnosed annually among Americans age 65 or older could drop by nearly half by 2030 if everyone simply exercised more regularly and vigorously.

One of the next goals in PD treatment is to create guidelines for exercise prescriptions.

“We have long known exercise is good for Parkinson’s patients,” Giselle Petzinger, MD, associate professor of neurology at the University of Southern California’s Keck School of Medicine, tells the Post. “What we are trying to do now is further refine what we already know into practical applications for patients.”

Motor Skills and Speech Therapy
Lee Silverman was an individual with PD whose speech abilities were affected by the disease. This is a common occurrence, as published studies have found that some 70 to 90 percent of people with PD show some type of speech disorder during the course of the disease. Lorraine Ramig, PhD, now a research professor emeritus of speech, language, and hearing sciences at the University of Colorado Boulder, was called in to work with Silverman in 1987. The speech therapy Ramig and her colleagues developed was named in Silverman’s honor as Lee Silverman Voice Treatment (LSVT) LOUD.

LSVT LOUD retrains soft-talking individuals with PD to use their voice at a more conventional volume. “Key to the treatment is helping people ‘recalibrate’ their perceptions so they know how loud or soft they sound to other people and can feel comfortable using a stronger voice at a normal loudness level,” the group’s website explains.

The group subsequently launched LSVT BIG, offering therapy to recalibrate motor skills, including both small-motor tasks like buttoning a shirt and large-motor skills such as maintaining balance while walking.

Nutrition and Psychobiotics
Diet is key to overall health, but certain “neuroprotective” foods may be especially beneficial to those with Parkinson’s. “In PD, there are some foods that may help to ease symptoms and help brain health, while others can affect the way medications work,” states the Parkinson’s Foundation website. “While there are many things about PD that cannot be changed, the informed choice of diet can help people to live better with the disease.”

The foundation offers the following advice:

• Anti-inflammatory foods are important for brain and overall health. These include oily fish, like salmon, tuna, and mackerel; dark leafy green vegetables, like spinach, Swiss chard, kale, and collard greens; as well as soy products and herbs such as rosemary. Fats like medium-chain triglycerides may also tamp down inflammation: Coconut oil is a good source. (See “5 Rules for Anti-Inflammatory Eating” for more.)
• Antioxidants in foods can also protect the brain. They fight free radical molecules that can damage neurons and other healthy cells. Purple and red fruits, like blueberries and raspberries, contain a group of antioxidants called anthocyanins, which, according to one study, can increase blood flow to and activate areas of the brain that control, memory, attention, and language. Studies also find that drinking green tea, which has the antioxidant-like catechin EGCG, has both anti-inflammatory and antioxidant effects.
• Nuts and spices also offer strong neuroprotection. Nuts deliver healthy oils, essential fatty acids, minerals, vitamins, and antioxidants. Among the best are walnuts, pistachios, macadamia nuts, cashews, almonds, and Brazil nuts. Spices include turmeric (which offers the powerful anti-inflammatory curcumin) and Ceylon cinnamon, which in animal studies has shown potential for normalizing neurotransmitter levels and other PD brain changes. (Turmeric is a potent, anti-inflammatory spice with a wide range of promising therapeutic properties. See “The Health Benefits of Turmeric” for more on this healing spice.)

The connection between Parkinson’s and the gut microbiome — the trillions of microbes in your intestines — is one of the newest, most innovative fields of PD research. More research is needed, and ongoing trials are looking at probiotics and prebiotics that may affect PD, including helping with side effects such as constipation.

Probiotics are living microorganisms found in fer­mented foods, such as yogurt, kimchi, and sauerkraut, and available in supplement form; they can help create and sustain a diverse microbiome, supporting the intestinal lining and enhancing nutrient absorption, which aids overall digestive health. Prebiotics are types of indigestible, fermentable fiber that help the growth of the beneficial bacteria.

Future therapy may include “psychobiotics” — a combination of beneficial bacteria that can influence your neurological health and mental well-being via the gut–brain axis. (For more on the power of your microbiome to heal and protect your brain, from neurologist David Perlmutter, MD, FACN, ABHIM, see “Healthy Gut, Healthy Brain.”)

Early-Onset Parkinson’s

Actor Michael J. Fox was just 29 in 1990 when he first noticed a tremor in his pinkie. The trembling wouldn’t stop: It was like his littlest finger was possessed. After rounds of tests and doctor’s visits, he was diagnosed with Parkinson’s, although he didn’t share this with the world for seven more years. In his 2002 memoir, he writes on the first page not of his stellar television and movie career but about PD.

The title of Fox’s autobiography? Lucky Man.

In interviews after revealing his diagnosis, Fox referred to his PD as a “gift” — an epithet that did not please others with the disease. As he clarifies in his book, “If it is a gift, it’s the gift that just keeps on taking.”

Instead, the gift Fox was describing was the personal journey Parkinson’s led him on.

“These last 10 years of coming to terms with my disease would turn out to be the best 10 years of my life — not in spite of my illness, but because of it,” he writes.

“Coping with the relentless assault and the accumulating damage is not easy. Nobody would ever choose to have this visited upon them. Still, this unexpected crisis forced a fundamental life decision: adopt a siege mentality — or embark upon a journey. Whatever it was — courage? acceptance? wisdom? — that finally allowed me to go down the second road (after spending a few disastrous years on the first) was unquestionably a gift — and absent this neurophysiological catastrophe, I would never have opened it, or been so profoundly enriched. That’s why I consider myself a lucky man.”

In the years since revealing his diagnosis, Fox used his celebrity status to make himself the face of PD. And in 2000 he launched the Michael J. Fox Foundation for Parkinson’s Research, which remains one of the primary organizations worldwide dedicated to ensuring the development of improved therapies for those living with PD — and to ultimately finding a cure for the disease.

Age may be a key risk factor for Parkinson’s, but it is not just an elderly person’s disease, as Fox’s story shows. An estimated 4 percent of people with PD are diagnosed before age 50.

Ending Parkinson’s

In their book Ending Parkinson’s Disease, four leading experts — Ray Dorsey, MD; Todd Sherer, PhD; Michael Okun, MD; and Bastiaan Bloem, MD, PhD — offer a prescription for curtailing the disease. Their action plan is summarized in the acronym PACT.

Prevent:

• Ban herbicides and pesticides like paraquat and solvents like trichloroethylene. Reduce your risk of exposure if you work with such chemicals by wearing masks, gloves, and protective clothing. Accelerate the cleanup of contaminated sites.
• Eat healthy. Buy organic when possible and avoid foods that may be contaminated with herbicides and pesticides. Wash your produce thoroughly. Eat a Mediterranean or similar low-carb, plant-based diet.
• Drink clean water. Test your water and use water filters to reduce exposure to chemical contaminants.
• Exercise. There is no exact optimal amount of exercise, but David K. Simon, MD, PhD, a neurology professor at Harvard Medical School and director of the Parkinson’s Disease and Movement Disorders Center at Beth Israel Deaconess Medical Center (who was not involved with the book), generally recommends at least 150 minutes per week of at least moderate-intensity exercise. Still, even less than this recommended amount likely has benefits, he says.
• Protect your head. Avoid activities with a high risk of concussion or wear a protective helmet.

Advocate:

• Share your story: Attend a Parkinson’s support group in person or online.
• Call your government representatives and push for more research funding via the National Institutes of Health.
• Donate to Parkinson’s foundations and stay informed.

Care:

• Get the care you want and need by going to a medical center that specializes in Parkinson’s.
• Advocate for training of more specialists and clinicians in PD care.
• Expand access to care. Ask your government representatives to request ongoing Medicare coverage of telemedicine so Parkinson’s care is available to more patients.

Treat:

• Consider genetic testing to assess your family history regarding Parkinson’s.
• Join a clinical study. As Jim Hunt, who has Parkinson’s, explained during a break in a Rock Steady Boxing class, “I’m a research subject volunteer. It’s not going to help me, but it may help the next generation.”
