World Parkinson’s Day

by

Don’t know if it’s a cause for celebration or awareness, but here it is. World Parkinson’s Day , April 11, 2023. (If I managed to get my days right – seems I’m correct).

Anyway, to commemorate this day, I shall present some of my songs and “Parkinson’s Parodies©” that I’ve composed and or written lyrics to since having been diagnosed with Parkinson’s Disease in late 2011:

Submitted to the World Parkinson’s Coalition (WPC) this year as an entry in their song contest an original tune;

No Estoy Borracho

Also submitted to the WPC, a “Parkinson’s Parody©” based on Fleetwood Mac’s song “Don’t Stop”:

Don’t Stop Moving To The Music

Previously submitted to the WPC, but not this year,

Parkinson’s Anthem (We Ain’t Givin’ Up Hope”

… And that’s enough for today… I have an appointment with my Movement Disorders Specialist and so I gotta go now.

I’m not sure why the line numbers were included in the PDF, my guess is that it is/was pre-publication. At any rate, it just adds to the body of evidence that rhythm and movement helps get rid of the blues. 

Exploring the Use of Music to Promote Physical Activity Adherence: An Integrated Theoretical Approach. Kyoung Shin Park1*, David M. Williams, Jennifer L. Etnier  

Abstract …

Music can help people make more positive evaluations of acute exercise as an affective and
113 ergogenic stimulant. A recent meta-analysis of 139 studies revealed that listening to music during
114 acute bouts of exercise and sport activities increases positive affective valence (g = 0.48, CI [0.39,
115 0.56]), reduces ratings of perceived exertion (RPE; g = 0.22, CI [0.14, 0.30]), enhances physical
116 performance (g = 0.31, CI [0.25, 0.36]), and improves oxygen consumption (VO2max; g = 0.15, CI
117 [0.02, 0.27]) compared with activities without music (Terry et al., 2020). These findings support the
118 notion that music helps physical activity to be more joyous, less arduous, and more energetic and
119 efficient, arguably motivating the exerciser to join additional bouts. It is noteworthy that the
120 beneficial effects of music on affect and RPE were not moderated by physical activity intensity in the
121 meta-analysis (Terry et al., 2020), which indicates that music provides psychological benefits across
122 the full range of intensities.

Prodromal symptoms, Parkinson’s Disease (PD), and that old song and dance…

by

Here’s a few studies that came up in my news feed from  PubMed Central (PMC) or elsewhere for articles recently published on the topics in which I’m interested – namely, prodromal symptoms related to PD, the relationship of REM sleep disorder and depression to PD, and, of course, the use of singing and dance therapies as complementary approaches to dealing with the symptoms of PD.

Prevalence and duration of non-motor symptoms in prodromal Parkinson’s disease

The prevalence and duration of non-motor symptoms (NMS) in prodromal Parkinson’s disease (PD) has not been extensively studied. The aim of this study was to determine the prevalence and duration of prodromal NMS (pNMS) in a cohort of patients with recently diagnosed PD.

…subtracted the duration of the presence of each individual NMS reported from the duration of the earliest motor symptom. NMS whose duration preceded the duration of motor symptoms were considered a pNMS. Individual pNMS were then grouped into relevant pNMS clusters based on the NMSQuest domains. Motor subtypes were defined as tremor dominant, postural instability gait difficulty (PIGD) and indeterminate type according to the Movement Disorder Society Unified Parkinson’s Disease Rating Scale revision.

Results: Prodromal NMS were experienced by 90.3% of patients with PD. … males reporting more sexual dysfunction, forgetfulness and dream re-enactment, whereas females reported more unexplained weight change and anxiety. There was a significant association between any prodromal gastrointestinal symptoms and urinary symptoms  and the PIGD phenotype.[n.b.: phenotype includes inherent traits or characteristics that are observable]. [Emphases added].

Associations of Sleep Disorders With Depressive Symptoms in Early and Prodromal Parkinson’s Disease

Purpose: To explore the effect of sleep disorders, including the probable rapid eye movement (REM) sleep behavior disorder (pRBD) and the daytime sleepiness, on depressive symptoms in patients with early and prodromal PD.

5-year follow-up study showed that sleep disorders, including pRBD and daytime sleepiness, were associated with the increased depressive-related score in individuals with early and prodromal PD.

Conclusion: … Sleep disorders, including pRBD and daytime sleepiness, are associated with depression at baseline and longitudinally, …  partially mediated by the autonomic dysfunction in early and prodromal PD, …  implication that sleep management is of great value for disease surveillance.

Group therapeutic singing improves clinical motor scores in persons with Parkinson’s disease

Abstract
Background Previous reports suggest that group therapeutic singing (GTS) may have a positive effect on motor symptoms in persons with Parkinson’s disease (PD).

Objective To determine the effect of a single session of GTS on clinical motor symptoms.

Methods Clinical motor symptom assessment was completed immediately before and after 1 hour of GTS in 18 participants.

Results A significant decrease in average scores for gait and posture and tremor, but not speech and facial expression or bradykinesia was revealed.

Conclusion These results support the notion that GTS is a beneficial adjuvant therapy for persons with PD that warrants further research.

Sing!

by

What research has found its way into the email inbox recently?

Although singing is a nearly universal human behavior, many adults consider themselves poor singers and avoid singing based on self-assessment of pitch matching accuracy during singing (here referred to as singing accuracy), in contrast to the uninhibited singing exhibited by children. In this article, I report results that shed light on how singing accuracy changes across the lifespan, using data from a large online sample, including participants ranging from 6 to 99 years old. Results suggest that singing accuracy improves dramatically from childhood to young adulthood, unperturbed by voice changes during adolescence, and remain at a similarly high level for the remainder of life, exhibiting no strong tendency toward age-related decline. Vocal or instrumental musical training has significant positive effects on singing accuracy, particularly in childhood, though there was no evidence for gender differences. Finally, pitch discrimination varied with age similarly to singing accuracy, in support of views that singing accuracy reflects sensorimotor learning. Taken together, these results are consistent with the view that singing accuracy is a learned motor skill that benefits from engagement and can remain a fruitful endeavor into old age. (emphasis added).

citation: Singing accuracy across the lifespan
Peter Q. Pfordresher preprint  article accessed 6-19-22 at https://nyaspubs.onlinelibrary.wiley.com/doi/10.1111/nyas.14815

Basically, this says that if you learned how sing accurately when you were young, you can probably sing well into your later years. And, since singing is a learned motor skill, one might assume that it can be learned even as one gets older.

Relevance to folks with Parkinson’s Disease (PD)?

Vocal strength exercises, such as those provided by Power for Parkinson’s as free YouTube video classes, can help with specific Parkinson’s related symptoms:

Many people with PD speak quietly and in one tone; they don’t convey much emotion. Sometimes speech sounds breathy or hoarse. People with Parkinson’s might slur words, mumble or trail off at the end of a sentence. Most people talk slowly, but some speak rapidly, even stuttering or stammering.

Parkinson’s motor symptoms, such as decreased facial expression, slowness and stooped posture, may add to speech problems. These can send incorrect non-verbal cues or impact the ability to show emotion. Source: https://www.michaeljfox.org/news/speech-swallowing-problems accessed June 20, 2022  (emphasis added).

Since our vocal cords are muscles, and singing is a learned motor skill, we can strengthen those muscles and push against the progressive, degenerative symptoms of PD through exercises that:

  • remind us to breathe deeply to sustain vocal volume,
  • improve our posture in order to enable deep breathing,
  • exercise the muscles of the face and mouth
  • to enable crisp diction instead of slurring and mumbling, and that
  • support emotional expression through inflection and singing.

And “Everybody Knows” that if exercise is fun, one is more likely to continue doing it.

Full disclosure: The author has attended Power for Parkinson’s ® vocal exercise classes since their inception in 2016, and co-founded a participant organized singing group (with the late Jeff Berke) in 2015.  Therefore, he might be (definitely is) biased in favor of this modality of treatment for vocal and speech related symptoms of PD.

Basic human rights

by

I don’t have access to the content of this book, but I was struck by the abstract to this chapter:

The right to an education is an important human right and is regulated in considerable detail in Articles 13 and 14 of the International Covenant on Economic, Social and Cultural Rights as well as in Articles 28 and 29 of the UN Convention on the Rights of the Child. With the sole exception of the United States, all United Nations member States have accepted the right to education as a legally binding human right that needs to be implemented in their domestic systems. (emphasis added)

What’s wrong with education in the United States? The U.S.A. hasn’t accepted it as a legally binding human right. No wonder that (well, I won’t go there today).

eBook ISBN 9781003043478

Book Description
The Routledge Companion to Music and Human Rights is a collection of case studies spanning a wide range of concerns about music and human rights in response to intensifying challenges to the well-being of individuals, peoples, and the planet. It brings forward the expertise of academic researchers, lawyers, human rights practitioners, and performing musicians who offer critical reflection on how their work might identify, inform, or advance mutual interests in their respective fields. The book is comprised of 28 chapters, interspersed with 23 ‘voices’ – portraits that focus on individuals’ intimate experiences with music in the defence or advancement of human rights – and explores the following four themes: 1) Fundamentals on music and human rights; 2) Music in pursuit of human rights; 3) Music as a means of violating human rights; 4) Human rights and music: intrinsic resonances.

The book is scheduled for publishing on May 31, 2022. $250 for print, under $50.00 USD for ebook format.

I really gotta look into becoming a student or getting associated with an organization or library that would allow me to access research articles, journals, ans books. It’s the one thing I miss most about IBM: access to technical journals through the library. That, and the IBM Club band, aka the Blue Diamonds Jazz Orchestra (BDJO). 

While not exactly fitting in with music, but maybe under basic human rights (free speech, anyone?), here is an open access article reporting on the results of the Parkinson’s Voice initiative:

Conclusion first:

Sustained vowels may provide an objective, robust and streamlined approach towards informing PwP subtype assignment. The current study’s findings corroborate part of the PD research literature indicating the presence of four PD subtypes having been thoroughly validated on a large PwP cohort and externally validated on two additional PwP cohorts. There are important practical implications of defining PD subtypes using data that is easy to self-collect remotely such as speech signals and in particular sustained vowel /a/ phonations: they enable large-scale investigations and may bring us a step closer towards more personalized medicine approaches and targeted clinical management. The key limitation of the study is that we do not have additional clinical labels (e.g. UPDRS) or other self-reported outcome measures to map the resulting PD subtypes onto something that would be more tangible and comparable to related PD subtype studies. Future work could explore the extent subtypes form useful markers of symptom severity progression and conversely how PD progression might affect subtype membership for individual PwP. Similarly, further work could integrate additional modalities to speech to incorporate longitudinal passively collected modalities and self-reports which could be capturing PD-related symptoms, e.g. via using smartphones and wearables along the lines we have explored for mental disorders [64], [67]–[70]. Collecting additional modalities at scale using increasingly affordable technologies may provide new insights towards understanding PD subtypes which may translate into understanding individual PwP similarities, related PwP symptom trajectories, and ultimately lead to better symptom management strategies.

and from the abstract:

Purpose
People diagnosed with Parkinson’s (PwP) exhibit a diverse manifestation of heterogeneous symptoms which likely reflect different subtypes. However, there is no widely accepted consensus on the criteria for subtype membership assignment. We explored clustering PwP using a data-driven approach mining speech signals.
…
Results
We selected 21 dysphonia measures and found four main clusters which provide tentative insights into different dominating speech-associated characteristics (cophenetic coefficient=0.72, silhouette score=0.67). The cluster findings were consistent across the three PVI cohorts, strongly supporting the generalization of the presented methodology towards PwP subtype assignment, and were independently visually verified in 2D projections with t-SNE.

and that’s all I have for today, folks!

Keep on moving to (and making) music

by

The evidence that rhythm, movement, and making music continues to accumulate as a therapeutic approach to address the symptoms and Quality of Life issues related to Parkinson’s Disease (PD).

Today we look at an article just out in Frontiers of Human Neuroscience, titled

Rhythm and Music-Based Interventions in Motor Rehabilitation: Current Evidence and Future Perspectives  

Over the last quarter of a century, increasing research results point to rhythm and music as effective and useful tools for treatment and rehabilitation of people with neurological disorders. This article reviews the evidence for four different approaches, what the consensus is at the present time, and, of course, suggests future directions.

The authors look at four different approaches:

  1. Rhythmic Auditory Stimulation (RAS)
  2. Music-Supported Therapy (MST)
  3. Therapeutic Instrumental Music Performance therapy (TIMP) and
  4. Patterned Sensory Enhancement (PSE)

The consensus of recent meta-analyses and systematic reviews is that, for Parkinson’s Disease (PD), is that RAS is an effective tool for improving gait, stride, and speed – folks walk faster and with longer steps with RAS. Additionally, evidence is showing that it also reduces freezing of gait (FOG), improves balance and reduces the occurrence of falls.

Neither MST nor TIMP have been studied much beyond the rehabilitation of stroke patients. They involve practicing on a keyboard or drums, beginning with the patient’s comfort level and increasing in difficulty. Some studies have begun to be used to investigate effectiveness as treatments for PD.  Some have shown improvements in motor dexterity. More research is needed, but in the meantime, learning to play drums or keyboards can’t hurt, and may enrich one’s quality of life (QOL).

Growing evidence in neurological and brain imaging have shown increased activity in the auditory and motor areas of the brain, indicating that brain plasticity might be achieved through music and rhythmic interventions. The authors note that RAS has been well studied with stroke and PD populations, but not with other movement disorders and Alzheimer’s populations. In addition MST and TIMP have only begun to be investigated as a means of restoring fine motor coordination.

The authors also call for neuroimaging use in studies, to better understand the physiological basis of the rehabilitation process. They point out the gaps in research and hope to provide a framework for future research – not so much a roadmap, I would think, but a laying out of what we know and what we don’t know, and what kinds of studies are needed to answer the questions about what we don’t know..  They state that “musical rhythm is a powerful tool” for therapy, and our understanding and exploration of how it modulates brain networks is in the initial stages.

 In other words, “We’ve only just begun.”

Meanwhile: Don’t stop moving to the music.

What to do?

by

When it comes to diseases like cancer, the UK medical folks have decided that the “fighting” and “warrior” mentality are counter-productive. For one, this mindset causes people to delay seeking treatment. I don’t have the exact citation at hand, but it is referenced in this blog somewhere, and you’re welcome to search for it. (Thankfully, this is not a dissertation or scholarly article, or I couldn’t have written the previous sentence and gotten away with it).

But when it comes to exercise as a good way to slow, and sometimes reverse the physical or cognitive symptoms of Parkinson’s Disease (PD), there ain’t no doubt in some folks minds that dance is one of the finer things around to combine aerobic exercise, movements, and cognitive challenges to build new connections between neurons in the brain.

From the Digital Commons at Sarah Lawrence College comes this Master’s Thesis:

Rajan, Sneha, “Embodied Medicine: Integrating Dance/Movement Therapy into Physical Medicine & Rehabilitation” (2021). Dance/Movement Therapy Theses. 79. https://digitalcommons.slc.edu/dmt_etd/79

Long story short: “Overall, physiatry and dance/movement therapy have separately helped so many people but developing a synergy between these fields has the potential to transform rehabilitative medicine.”(emphasis added).

Specifically addressing Parkinson’s Disease issues, she writes:

For individuals with Parkinson’s disease, studies have shown that physical rehabilitation is an effective way to manage motor and non-motor symptoms (Mitra et al., 2020). However, maintaining motivation for treatment is difficult because of progressive difficulties with physical disability and co-existing emotional factors, so as a result not many adults engage with enough physical exercise (Mitra et al., 2020). By incorporating cognitive, emotional, and social components, the exercise environment could become more engaging and multidimensional (Mitra et al., 2020). One experimental study examined the effects of dance/movement therapy sessions on the cognition, quality of life, and motor symptoms of patients with Parkinson’s disease (Mitra et al., 2020). They used a variety of techniques such as targeted body exercises, memory games, movement improvisation, guided imagery, rhythm work, contact improvisation, mirroring, body coordination and movement reflexes (Mitra et al., 2020). Music was also used to incorporate rhythm and sensory motor cues (Mitra et al., 2020).

As a result, participants showed a significant increase in cognitive functioning and a decrease in Parkinson’s related health difficulties. Additionally, patients reported improvements in coordination, mood, and memory (Mitra et al., 2020). Another study analyzed the effectiveness of music-based movement therapy on gait related activities in Parkinson’s patients (Dreu et al., 2011). They examined both individual music-based gait training and partnered-dance interventions. The music provides rhythmic cues that help synchronize movements and also facilitates emotional responses in the participants (Dreu et al., 2011). Participants showed improvements in walking velocity and balance (Dreu et al., 2011). (Emphasis added.)

 If I were to judge this Master’s thesis, I would suggest more sources, and more recent ones than the one she used in material about Parkinson’s in the paragraphs before the ones I quoted above. But I’m not on the faculty of Sarah Lawrence College, so that’s their loss.

And the answer to the question posed in the title of this blog entry “What to do?” is simple: Don’t Stop Moving To The Music!

Cannabis and Parkinson’s Disease (PD)

by

This article popped up in my email alerts. Although I do not have access to the journal in which it appeared, I thought I would post it anyway, along with several article titles that appeared in the same journal. (If my former employer would grant me access to their technical library, I would be most grateful, and might even forego any patent filing awards that I would be eligible for if I hadn’t retired. I come across at least one new Human-Computer Interface issue that could be solved each week, But I digress). (The actual link to the article was in Medscape News).

Despite high interest (no pun intended(?)) in the use of cannabis as a treatment for Parkinson’s Disease symptoms, this study  finds that actual use remains low (at least in Germany). The article appeared in  Journal of Parkinson’s Disease: Yenilmez, Ferhat et al. ‘Cannabis in Parkinson’s Disease: The Patients’ View’. 1 Jan. 2021 : 309 – 321. 11, no. 1, pp. 309-321, 2021.

Sadly, it is not available as open access, but fortunately the methods and results provide adequate data regarding the study.

Abstract:

Background: Little is known about the patients’ view on treatment with medical cannabis (MC) for Parkinson’s disease (PD). Objective: To assess the PD community’s perception of MC and patients’ experience with MC.Abstract:

Methods: Applying a questionnaire-based survey, we evaluated general knowledge and interest in MC as well as the frequency, modalities, efficacy, and tolerability of application. Questionnaires were distributed nationwide via the membership journal of the German Parkinson Association and locally in our clinic to control for report bias.

Results: Overall, 1.348 questionnaires (1.123 nationwide, 225 local) were analysed. 51% of participants were aware of the legality of MC application, 28% of various routes of administration (ROA) and 9% of the difference between delta9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD).

PD-related cannabis use was reported by 8.4% of patients and associated with younger age, living in large cities and better knowledge about the legal and clinical aspects of MC. Reduction of pain and muscle cramps was reported by more than 40% of cannabis users. Stiffness/akinesia, freezing, tremor, depression, anxiety and restless legs syndrome subjectively improved for more than 20% and overall tolerability was good. Improvement of symptoms was reported by 54% of users applying oral CBD and 68% inhaling THC-containing cannabis. Compared to CBD intake, inhalation of THC was more frequently reported to reduce akinesia and stiffness (50.0% vs. 35.4%; p < 0.05). (emphasis added) Interest in using MC was reported by 65% of non-users.

Conclusion: MC is considered as a therapeutic option by many PD patients. Nevertheless, efficacy and different ROA should further be investigated.

The adjusted odds ratios (ORs) in model 2, which was adjusted for all potential confounders, for hypothyroidism and hyperthyroidism in the PD group were 1.25 (95% confidence interval (CI) 1.01–1.55, p  = 0.044) and 1.37 (95% CI 1.13–1.67, p  = 0.002), respectively.

Research on the arts and outcomes related to Parkinson’s – and more related research and hypotheses

by

For our first article, we have a review on group based dance, singing, music, and theatrical treatments on a variety show of outcomes. 

A systematic review of active group-based dance, singing, music therapy and theatrical interventions for quality of life, functional communication, speech, motor function and cognitive status in people with Parkinson’s disease

Basically, they found that the arts seemed to have positive effects for folks with PD – but that not all types of arts were evaluated against all of the outcomes listed. So “More research is needed” to look into all aspects. But it’s a good thing.

Next up is a review of the effects of oxytocin and the effects of music on the human brain. And on social behavior and bonding. While not specifically directed at Parkinson’s disease, it is certainly applicable to treatments for people with Parkinson’s.

Links Between the Neurobiology of Oxytocin and Human Musicality

 It is argued that many of these characteristics of oxytocin biology closely mirror the diverse effects that music has on human cognition and emotion, providing a link to the important role music has played throughout human evolutionary history and helping to explain why music remains a special prosocial human asset. Finally, it is suggested that there is a potential synergy in combining oxytocin- and music-based strategies to improve general health and aid in the treatment of various neurological dysfunctions.

Keywords: oxytocin, music, dance, reward, empathy, trust, therapy

If there is a link between neurobiology and music, then it stands to reason that music played a part in the evolution of modern Homo sapiens. That is the topic of the brief review of:

Music and the Meeting of Human Minds by Alan Harvey

The author addresses

  1. when and why  modern humans evolved musical behaviors,
  2. the evolutionary relationship between music and language, and 
  3. why humans, perhaps unique among all living species, universally
    continue to possess two complementary but distinct communication streams.

He argues that “early in our history, the unique socializing and harmonizing power of music acted as an essential counterweight to the new and evolving sense of self, to an emerging sense of individuality and mortality that was linked to the development of an advanced cognitive capacity and articulate language capability.”

Dopamine is one of the keywords, so it should be of interest to People with Parkinson’s.

Another article along similar lines is Music as a coevolved system for social bonding,  The authors put forth an hypothesis and

make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding (MSB) hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music.

Where it’s at (at this moment )

by

As a person who was diagnosed in late 2011 with Parkinson’s disease after several years of treatment for Essential Tremors that had gotten uncontrollable, I had Deep Brain Stimulation (DBS) shortly thereafter (I had already decided to go for DBS to control the tremors, and in the additional testing, rigidity was observed, allowing the diagnosis).

Since then, thanks to a supportive care partner, a supportive community that provides exercise and dance classes, and now vocal exercises (singing) which I had initiated in 2015 along with a friend, now deceased, I am able to function fairly well. I consider my self ” the luckiest guy” to paraphrase Lou Gehrig.

So instead of my usual posting of an article or a few on a specific topic, I thought I would post this YouTube video documenting my current situation (albeit somewhat exaggerated for dramatic effect) as far as Parkinson’s Disease goes:

I Blame The Parkinson’s
